Equated Monthly Installment (EMI) is the fixed payment amount borrowers make to lenders each month to repay a loan. EMIs consist of both the principal and the interest, and the amount remains constant throughout the loan tenure. The formula for calculating EMI is:

where:

• P = Principal amount (loan amount),
• r = Monthly interest rate (annual interest rate divided by 12 and expressed as a decimal),
• n = Number of monthly installments (loan tenure in months).

Components of EMI Calculation:

• Principal (P):

This is the amount initially borrowed from the lender. It’s the base amount on which interest is calculated. Higher principal amounts lead to higher EMIs, as the overall amount owed is greater.

• Interest Rate (r):

The rate of interest applied to the principal impacts the EMI significantly. Interest rate is typically given annually but needs to be converted into a monthly rate for EMI calculations. For instance, a 12% annual rate would be converted to a 1% monthly rate (12% ÷ 12).

• Loan Tenure (n):

The number of months over which the loan is repaid. A longer tenure reduces the monthly EMI amount because the total loan repayment is spread over a greater number of installments, though this may lead to higher total interest paid.

Types of EMI Calculation Methods:

• Flat Rate EMI:

Here, interest is calculated on the original principal amount throughout the tenure. The formula differs from the reducing balance method and generally results in higher EMIs.

• Reducing Balance EMI:

This is the most common method for EMI calculations, where interest is calculated on the outstanding balance. As the principal reduces over time, interest payments decrease, leading to an overall lower cost compared to the flat rate.

Importance of EMI Calculation:

• Assess Affordability:

Borrowers can determine if the EMI amount fits within their monthly budget, ensuring they can make payments consistently.

• Plan Finances:

Knowing the EMI in advance helps in planning for other financial obligations and expenses.

• Compare Loan Options:

Borrowers can evaluate different loan offers by comparing EMIs for similar loan amounts and tenures but with varying interest rates.

Sinking Fund is a financial mechanism used to set aside money over time for the purpose of repaying debt or replacing a significant asset. It acts as a savings plan that allows an organization or individual to accumulate funds for a specific future obligation, ensuring that they have enough resources to meet that obligation without straining their financial situation.

Purpose of a Sinking Fund:

The primary purpose of a sinking fund is to manage debt repayment or asset replacement efficiently.

• Reduce Default Risk:

By setting aside funds regularly, borrowers can reduce the risk of default on their obligations. This practice assures lenders that the borrower is financially responsible and prepared to meet repayment terms.

• Facilitate Large Purchases:

For organizations, sinking funds can help manage significant future expenditures, such as replacing machinery, vehicles, or technology. This ensures that funds are available when needed, mitigating the impact on cash flow.

• Enhance Financial Planning:

Establishing a sinking fund encourages better financial planning and discipline. Organizations can forecast their future cash requirements, making it easier to allocate resources appropriately.

Structure of a Sinking Fund:

• Regular Contributions:

The entity responsible for the sinking fund makes regular contributions, typically monthly or annually. The amount of these contributions can be fixed or variable based on a predetermined plan.

• Interest Earnings:

The contributions are usually invested in low-risk securities or interest-bearing accounts. This investment allows the sinking fund to grow over time through interest earnings, ultimately increasing the amount available for future obligations.

• Target Amount:

The sinking fund is established with a specific target amount that reflects the total debt or asset replacement cost. The time frame for reaching this target is also defined, ensuring that contributions align with the due date for the obligation.

Benefits of a Sinking Fund:

• Financial Stability:

By accumulating funds over time, sinking funds contribute to financial stability, reducing the pressure to secure large amounts of money at once.

• Improved Creditworthiness:

A well-managed sinking fund can enhance an organization’s credit rating. Lenders view sinking funds as a positive indicator of an entity’s ability to manage its debts responsibly.

• Cost Management:

Sinking funds help manage the cost of large purchases or debt repayments by spreading the financial burden over time, reducing the impact on cash flow.

• Flexibility:

The structure of a sinking fund can be adjusted based on changing financial circumstances. Contributions can be increased or decreased as needed, providing flexibility in financial planning.

• Risk Mitigation:

By setting aside funds in advance, entities can mitigate the risks associated with sudden financial obligations, ensuring they are prepared for unexpected expenses or economic downturns.

Practical Applications of Sinking Funds:

• Corporate Bonds:

Many corporations issue bonds that require a sinking fund to be established. The company sets aside money regularly to repay bondholders at maturity or periodically throughout the life of the bond.

• Municipal Bonds:

Local governments often use sinking funds to repay municipal bonds. This practice ensures that they can meet their obligations without significantly impacting their budgets.

• Asset Replacement:

Businesses may establish sinking funds for replacing equipment or vehicles. By planning ahead, they can avoid large capital outlays and maintain operations without disruption.

• Real Estate:

Property management companies may set up sinking funds for the maintenance and eventual replacement of common areas or amenities within residential complexes.

• Educational Institutions:

Schools and universities may use sinking funds to save for future building projects or major renovations, ensuring they can finance these endeavors without resorting to debt.

Perpetuity refers to a financial instrument or cash flow that continues indefinitely without an end. In simpler terms, it is a stream of cash flows that occurs at regular intervals for an infinite duration. The present value of a perpetuity can be calculated using the formula:

PV = C/ r

Where,

C is the cash flow per period

r is the discount rate.

The concept of perpetuity has several important functions in finance and investment analysis. Here are eight key functions of perpetuity:

• Valuation of Investments:

Perpetuity provides a method for valuing investments that generate constant cash flows over an indefinite period. This is particularly useful in valuing companies, real estate, and other assets that are expected to generate steady income streams indefinitely. By calculating the present value of these cash flows, investors can determine the fair value of such assets.

• Determining Fixed Income Securities:

Perpetuities are often used in valuing fixed income securities like preferred stocks and bonds that pay a constant dividend or interest indefinitely. Investors can assess the attractiveness of these securities by comparing their present value to the market price, thus aiding investment decisions.

• Simplifying Financial Analysis:

The concept of perpetuity simplifies complex financial models by allowing analysts to consider cash flows that extend indefinitely. This simplification is particularly valuable in scenarios where cash flows are expected to remain constant over a long period, providing a clearer picture of an investment’s worth.

• Corporate Valuation:

In corporate finance, perpetuity is a critical component of valuation models, such as the Gordon Growth Model, which estimates the value of a company based on its expected future dividends. By considering dividends as a perpetuity, analysts can derive a more accurate valuation for firms with stable dividend policies.

• Real Estate Investment:

In real estate, perpetuity helps in evaluating properties that generate consistent rental income. Investors can use the perpetuity formula to estimate the present value of future rental cash flows, facilitating better decision-making regarding property purchases or investments.

• Retirement Planning:

Perpetuity can assist individuals in planning for retirement. By understanding how much they can withdraw from their retirement savings while maintaining a sustainable income level indefinitely, retirees can ensure financial security throughout their retirement years.

• Life Insurance Valuation:

Perpetuities play a role in life insurance products that provide lifelong benefits. The present value of future benefits can be calculated using the perpetuity concept, aiding insurers in pricing their products and ensuring they can meet future obligations.

• Evaluating Charitable Donations:

Nonprofit organizations can benefit from the concept of perpetuity when structuring endowments or perpetual funds. These funds are designed to provide a steady stream of income for ongoing operations, scholarships, or charitable initiatives. By understanding the present value of these perpetual cash flows, organizations can make informed decisions about resource allocation and fund management.

Calculating interest rate is not at all a difficult method to understand. Knowing to calculate interest rate can solve a lot of wages problems and save money while taking investment decisions. There is an easy formula to calculate simple interest rates. If you are aware of your loan and interest amount you can pay, you can do the largest interest rate calculation for yourself.

Using the simple interest calculation formula, you can also see your interest payments in a year and calculate your annual percentage rate.

Here is the step by step guide to calculate the interest rate.

How to calculate interest rate?

Know the formula which can help you to calculate your interest rate.

Step 1

To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. Here,

I = Interest amount paid in a specific time period (month, year etc.)

P = Principle amount (the money before interest)

t = Time period involved

r = Interest rate in decimal

You should remember this equation to calculate your basic interest rate.

Step 2

Once you put all the values required to calculate your interest rate, you will get your interest rate in decimal. Now, you need to convert the interest rate you got by multiplying it by 100. For example, a decimal like .11 will not help much while figuring out your interest rate. So, if you want to find your interest rate for .11, you have to multiply .11 with 100 (.11 x 100).

For this case, your interest rate will be (.11 x 100 = 11) 11%.

Step 3

Apart from this, you can also calculate your time period involved, principal amount and interest amount paid in a specific time period if you have other inputs available with you.

Calculate interest amount paid in a specific time period, I = Prt.

Calculate the principal amount, P = I/rt.

Calculate time period involved t = I/Pr.

Step 4

Most importantly, you have to make sure that your time period and interest rate are following the same parameter.

For example, on a loan, you want to find your monthly interest rate after one year. In this case, if you put t = 1, you will get the final interest rate as the interest rate per year. Whereas, if you want the monthly interest rate, you have to put the correct amount of time elapsed. Here, you can consider the time period like 12 months.

Please remember, your time period should be the same time amount as the interest paid. For example, if you’re calculating a year’s monthly interest payments then, it can be considered you’ve made 12 payments.

Also, you have to make sure that you check the time period (weekly, monthly, yearly etc.) when your interest is calculated with your bank.

Step 5

You can rely on online calculators to get interest rates for complex loans, such as mortgages. You should also know the interest rate of your loan when you sign up for it.

For fluctuating rates, sometimes it becomes difficult to determine what a certain rate means. So, it is better to use free online calculators by searching “variable APR interest calculator”, “mortgage interest calculator” etc.

Calculation of interest when rate of interest and cash price is given

• Where Cash Price, Interest Rate and Instalment are Given:

Illustration:

On 1st January 2003, A bought a television from a seller under Hire Purchase System, the cash price of which being Rs 10.450 as per the following terms:

(a) Rs 3,000 to be paid on signing the agreement.

(b) Balance to be paid in three equal installments of Rs 3,000 at the end of each year,

(c) The rate of interest charged by the seller is 10% per annum.

You are required to calculate the interest paid by the buyer to the seller each year.

Solution:

Note:

1. there is no time gap between the signing of the agreement and the cash down payment of Rs 3,000 (1.1.2003). Hence no interest is calculated. The entire amount goes to reduce the cash price.
2. The interest in the last installment is taken at the differential figure of Rs 285.50 (3,000 – 2,714.50).

(2) Where Cash Price and Installments are Given but Rate of Interest is Omitted:

Where the rate of interest is not given and only the cash price and the total payments under hire purchase installments are given, then the total interest paid is the difference between the cash price of the asset and the total amount paid as per the agreement. This interest amount is apportioned in the ratio of amount outstanding at the end of each period.

Illustration:

Mr. A bought a machine under hire purchase agreement, the cash price of the machine being Rs 18,000. As per the terms, the buyer has to pay Rs 4,000 on signing the agreement and the balance in four installments of Rs 4,000 each, payable at the end of each year. Calculate the interest chargeable at the end of each year.

(3) Where installments and Rate of Interest are Given but Cash Value of the Asset is Omitted:

In certain problems, the cash price is not given. It is necessary that we must first find out the cash price and interest included in the installments. The asset account is to be debited with the actual price of the asset. Under such situations, i.e. in the absence of cash price, the interest is calculated from the last year.

It may be noted that the amount of interest goes on increasing from 3rd year to 2nd year, 2nd year to 1st year. Since the interest is included in the installments and by knowing the rate of interest, we can find out the cash price.

Thus:

Let the cash price outstanding be: Rs 100

Interest @ 10% on Rs 100 for a year: Rs 10

Installment paid at the end of the year 110

The interest on installment price = 10/110 or 1/11 as a ratio.

Illustration:

I buy a television on Hire Purchase System.

The terms of payment are as follows:

Rs 2,000 to be paid on signing the agreement;

Rs 2,800 at the end of the first year;

Rs 2,600 at the end of the second year;

Rs 2,400 at the end of the third year;

Rs 2,200 at the end of the fourth year.

If interest is charged at the rate of 10% p.a., what was the cash value of the television?

Solution:

(4) Calculation of Cash Price when Reference to Annuity Table, the Rate of Interest and Installments are Given:

Sometimes in the problem a reference to annuity table wherein present value of the annuity for a number of years at a certain rate of interest is given. In such cases the cash price is calculated by multiplying the amount of installment and adding the product to the initial payment.

Illustration:

A agrees to purchase a machine from a seller under Hire Purchase System by annual installment of Rs 10,000 over a period of 5 years. The seller charges interest at 4% p.a. on yearly balance.

N.B. The present value of Re 1 p.a. for five years at 4% is Rs 4.4518. Find out the cash price of the machine.

Solution:

Installment Re 1 Present value = Rs 4.4518

Installment = Rs 10,000 Present value = Rs 4.4518 x 10,000 = Rs 44,518

Bonds are fixed-income securities that represent a loan from an investor to a borrower, typically a corporation or government. When purchasing a bond, the investor lends money in exchange for periodic interest payments and the return of the bond’s face value at maturity. Bonds are used to finance various projects and operations, providing a predictable income stream for investors.

Valuation of Bonds

The method for valuation of bonds involves three steps as follows:

Step 1: Estimate the expected cash flows

Step 2: Determine the appropriate interest rate that should be used to discount the cash flows.

& Step 3: Calculate the present value of the expected cash flows (step-1) using appropriate interest rate (step- 2) i.e. discounting the expected cash flows

Step 1: Estimating cash flows

Cash flow is the cash that is estimated to be received in future from investment in a bond. There are only two types of cash flows that can be received from investment in bonds i.e. coupon payments and principal payment at maturity.

The usual cash flow cycle of the bond is coupon payments are received at regular intervals as per the bond agreement, and final coupon plus principle payment is received at the maturity. There are some instances when bonds don’t follow these regular patterns. Unusual patterns maybe a result of the different type of bond such as zero-coupon bonds, in which there are no coupon payments. Considering such factors, it is important for an analyst to estimate accurate cash flow for the purpose of bond valuation.

Step 2: Determine the appropriate interest rate to discount the cash flows

Once the cash flow for the bond is estimated, the next step is to determine the appropriate interest rate to discount cash flows. The minimum interest rate that an investor should require is the interest available in the marketplace for default-free cash flow. Default-free cash flows are cash flows from debt security which are completely safe and has zero chances default. Such securities are usually issued by the central bank of a country, for example, in the USA it is bonds by U.S. Treasury Security.

Consider a situation where an investor wants to invest in bonds. If he is considering to invest corporate bonds, he is expecting to earn higher return from these corporate bonds compared to rate of returns of U.S. Treasury Security bonds. This is because chances are that a corporate bond might default, whereas the U.S. Security Treasury bond is never going to default. As he is taking a higher risk by investing in corporate bonds, he expects a higher return.

One may use single interest rate or multiple interest rates for valuation.

Step 3: Discounting the expected cash flows

Now that we already have values of expected future cash flows and interest rate used to discount the cash flow, it is time to find the present value of cash flows. Present Value of a cash flow is the amount of money that must be invested today to generate a specific future value. The present value of a cash flow is more commonly known as discounted value.

The present value of a cash flow depends on two determinants:

• When a cash flow will be received i.e. timing of a cash flow &;
• The required interest rate, more widely known as Discount Rate (rate as per Step-2)

First, we calculate the present value of each expected cash flow. Then we add all the individual present values and the resultant sum is the value of the bond.

The formula to find the present value of one cash flow is:

Present value formula for Bond Valuation

Present Value _n = Expected cash flow in the period n/ (1+i) ⁿ

Here,

i = rate of return/discount rate on bond
n = expected time to receive the cash flow

By this formula, we will get the present value of each individual cash flow t years from now. The next step is to add all individual cash flows.

Bond Value = Present Value ₁ + Present Value ₂ + ……. + Present Value _n

Present Value (PV) concept refers to the current worth of a future sum of money or stream of cash flows, discounted at a specific interest rate. It reflects the principle that a dollar today is worth more than a dollar in the future due to its potential earning capacity.

PV = FV / (1+r)^n

where

FV is the future value,

r is the discount rate,

n is the number of periods until payment.

This concept is essential in finance for assessing investment opportunities and financial planning.

Functions of Present Value:

• Valuation of Cash Flows:

PV allows investors and analysts to evaluate the worth of future cash flows generated by an investment. By discounting future cash flows to their present value, stakeholders can determine if the investment is financially viable compared to its cost.

• Investment Decision Making:

In capital budgeting, PV is crucial for assessing whether to proceed with projects or investments. By comparing the present value of expected cash inflows to the initial investment (cost), decision-makers can prioritize projects that offer the highest returns relative to their costs.

• Comparison of Investment Alternatives:

PV provides a standardized method for comparing different investment opportunities. By converting future cash flows into their present values, investors can effectively evaluate and contrast various investments, regardless of their cash flow patterns or timing.

• Financial Planning:

Individuals and businesses use PV for financial planning and retirement savings. By calculating the present value of future financial goals (like retirement funds), individuals can determine how much they need to save and invest today to achieve those goals.

• Debt Valuation:

PV is essential for valuing bonds and other debt instruments. The present value of future interest payments and the principal repayment is calculated to determine the fair market value of the bond. This valuation helps investors make informed decisions about purchasing or selling bonds.

• Risk Assessment:

Present Value helps in assessing the risk associated with investments. Higher discount rates, which account for risk and uncertainty, lower the present value of future cash flows. This relationship allows investors to gauge the risk-return trade-off of different investments effectively.

Future Value (FV) is the value of a current asset at a future date based on an assumed rate of growth. The future value (FV) is important to investors and financial planners as they use it to estimate how much an investment made today will be worth in the future. Knowing the future value enables investors to make sound investment decisions based on their anticipated needs.

FV calculation allows investors to predict, with varying degrees of accuracy, the amount of profit that can be generated by different investments. The amount of growth generated by holding a given amount in cash will likely be different than if that same amount were invested in stocks; so, the FV equation is used to compare multiple options.

Determining the FV of an asset can become complicated, depending on the type of asset. Also, the FV calculation is based on the assumption of a stable growth rate. If money is placed in a savings account with a guaranteed interest rate, then the FV is easy to determine accurately. However, investments in the stock market or other securities with a more volatile rate of return can present greater difficulty.

Future Value (FV) formula assumes a constant rate of growth and a single upfront payment left untouched for the duration of the investment. The FV calculation can be done one of two ways depending on the type of interest being earned. If an investment earns simple interest, then the Future Value (FV) formula is:

• Future value (FV) is the value of a current asset at some point in the future based on an assumed growth rate.
• Investors are able to reasonably assume an investment’s profit using the future value (FV) calculation.
• Determining the future value (FV) of a market investment can be challenging because of the market’s volatility.
• There are two ways of calculating the future value (FV) of an asset: FV using simple interest and FV using compound interest.

Functions of Future Value:

• Investment Growth Measurement:

FV is used to calculate how much an investment will grow over time. By applying a specified interest rate, investors can estimate the future worth of their initial investments or savings, helping them understand the potential returns.

• Retirement Planning:

FV plays a critical role in retirement planning. Individuals can determine how much they need to save today to achieve a desired retirement income. By calculating the future value of regular contributions to retirement accounts, they can set realistic savings goals.

• Loan Repayment Calculations:

For borrowers, FV is crucial in understanding the total amount owed on loans over time. It helps them visualize the long-term cost of borrowing, including interest payments, aiding in budgeting and financial decision-making.

• Comparison of Investment Opportunities:

FV provides a standardized way to compare different investment options. By calculating the future value of various investment opportunities, investors can evaluate which options offer the highest potential returns over a specified period.

• Education Funding:

Parents can use FV to plan for their children’s education expenses. By estimating future tuition costs and calculating how much they need to save now, parents can ensure they accumulate sufficient funds by the time their children enter college.

• Inflation Adjustment:

FV helps investors account for inflation when planning for future expenses. By incorporating an expected inflation rate into future value calculations, individuals and businesses can better estimate the amount needed to maintain purchasing power over time.
