EMI Calculator
Work out the equated monthly instalment on a loan, the total interest you will pay, and see every payment in the schedule.
Please note
How to use the EMI Calculator
- 1Enter the loan amount, the annual interest rate and the tenure.
- 2Switch the tenure between months and years if that is easier.
- 3Read the monthly instalment, total interest and total repayment.
- 4Open the schedule to see how each payment splits between interest and principal.
How it works
An EMI is a level payment: the same amount every month for the whole term. Each payment covers the interest that accrued on the outstanding balance, and whatever is left reduces the principal. Because the balance shrinks, the interest portion falls month by month and the principal portion rises — which is why early payments feel like they barely dent the loan.
The instalment itself comes from the standard annuity formula, using the monthly rate (annual rate ÷ 12) and the number of months.
The schedule is built in whole cents rather than by accumulating rounded floats, and the final instalment absorbs the rounding remainder. That is why the closing balance lands on exactly zero instead of a few cents adrift after 240 rows.
The formula
- P
- principal, the amount borrowed
- r
- monthly interest rate, the annual rate ÷ 12 ÷ 100
- n
- total number of monthly payments
When the rate is zero the formula collapses to P ÷ n, which the calculator handles separately.
Worked example
Borrowing 500,000 over 5 years at 9% a year
- Monthly rate r = 9 ÷ 12 ÷ 100 = 0.0075
- Number of payments n = 60
- EMI = 500000 × 0.0075 × 1.0075⁶⁰ ÷ (1.0075⁶⁰ − 1)
Result: 10,379.18 a month, repaying 622,750.59 in total — of which 122,750.59 is interest.
