How EMI is calculated
The monthly installment is calculated using the standard amortization formula, which accounts for the loan principal, the monthly interest rate, and the total number of monthly payments. This produces a fixed monthly payment where the interest portion is highest at the start of the loan and gradually shrinks as the principal is paid down.
Reading the numbers
Total interest shows how much you'll pay on top of the original loan amount over its full term — this is often the number people are most surprised by, especially on longer terms. Comparing the total interest across different loan terms and interest rates before committing can reveal significant savings from a shorter term or a better rate.
Frequently asked questions
Does this include fees or insurance in the monthly payment?
No. This calculates the core principal-and-interest payment only, using the standard amortization formula. Real loan offers often include additional fees, insurance, or taxes that would increase your actual monthly outlay.
What's the difference between total interest and total repayment?
Total repayment is the full amount you'll pay back over the life of the loan (all monthly payments added together). Total interest is just the portion of that which is interest, on top of the original amount borrowed.
How much does loan term length affect total interest?
Significantly. Stretching a loan over more years lowers the monthly payment but usually increases total interest paid, since interest accrues for longer. Shortening the term raises the monthly payment but can save a substantial amount over time.
What if my interest rate is 0%?
The calculator handles a 0% rate correctly by simply dividing the loan amount evenly across the number of payments, with no interest added.
