EMI stands for Equated Monthly Instalment. You get this option when you have to pay for something. If you are not eligible to pay a lump sum amount in return for a product or money, then you can go for EMI. 

EMIs are generally fixed for loans with a fixed interest rate. But they can change in the case of floating-rate loans. When the lender revises the applicable interest rate, the EMI amount, the loan tenure, or both can be adjusted according to the loan term. 

Your principal amount, time period, and the interest rate are the key factors that affect your EMI amount. All these factors decide what amount of EMI you are going to pay each month. 

An EMI is used in high-amount cases. Like if you bought a laptop worth 1,00,000, and currently you don't have that much money. You can pay this amount plus interest in the form of EMI every month for a specific time period. 

Similarly, EMI works on a loan. When you get a loan, you have to pay it via EMI every month. Most commonly EMI is used in consumer durable loans, education loans, vehicle loans, and home loans. 

How to Calculate EMI?

You take a loan, in return you need to pay the whole amount of loan as well as interest in it to the lender. If you can't afford paying this much at once you can pay it monthly for a specific time. This amount is Fixed and it is called EMI. Every EMI consists of two parts: principal and Interest. 

Principal is your borrowed money and interest is the percentage that you need to pay to the lender. In starting EMIs, a large portion is towards interest payment. The interest component gradually decreases and the principal repayment portion increases. 

Formula of EMI

EMI =

This formula contains important factors like principal amount, rate of interest, and the number of years/month.

Let's see how EMI is calculated with the example of Ayaan. 

Ayaan takes a personal loan of ₹5,00,000. The bank is charging 12% interest on loan for 5 years. So let's calculate how much EMI Ayaan has to pay. 

EMI =

P = Principal amount = ₹5,00,000

R = Rate of interest = 12% ( 1% month)

N = Number of years = 5 years 

if the annual interest rate is 12%, then R = 12% ÷ 12 = 1% per month (0.01).  A 5-year loan with monthly EMIs will have N = 60.

EMI = [₹5,00,000 × 0.01 × (1+0.01)^60] / [(1+0.01)^60-1]

        = ₹5,000 × [( 1.01)^60 / (1.01)^60-1]

        = ₹5,000 × 1.816696 / 1.816696 - 1

        = ~11,122.

That means, Ayaan has to pay ~11,122 every month until his loan is completed. 

Note: See, the EMI formula works only when the interest rate and repayment period are expressed in the same unit. But Most loans have monthly EMIs, the annual interest rate should be converted into a monthly rate and the tenure must be converted into months.

Conclusion

When you get a loan, you are liable to repay it within a specific time. But many times people do not have that much large amount to repay in one go. That time EMI comes in frame. The things that decide your EMI amount are interest rate, principal amount, and the time period of loan. If your principal or interest is high, your EMI also can increase. You can compare loan options, when you know how EMI is calculated. Plan your finances better, and choose a repayment schedule that suits your budget. So before taking any loan, always check the total interest payable, processing charges, and repayment terms. So that you can avoid financial stress and make informed borrowing decisions.
