- Principal$10,00080%
- Interest$2,45520%
Add $21 a month and you save $290 in interest, finishing 6 months sooner.
A rate of 8.00% instead of 9% would cost $289 less in interest and $4.82 less a month.Half the loan is repaid in year 3; the first year alone costs $833 in interest.

How EMI is calculated
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of monthly instalments. Every EMI is the same, but early on most of it is interest; over time the principal share grows. The year-by-year table above shows exactly how that shifts.
Why paying a little extra matters so much
Extra money paid with an EMI goes straight to the principal, so every later month charges interest on a smaller balance. On a 20-year loan, adding even 5% to the instalment can remove two or more years of payments. Use the extra payment field to see the exact interest and time saved for your loan, and check whether your lender charges a prepayment fee.
Reducing vs flat interest rate
This calculator uses the reducing-balance method, which is what banks use for home, car and personal loans: interest is charged only on what you still owe. A "flat rate" quoted by some lenders charges interest on the full original amount for the whole term, which works out to roughly 1.8× the reducing rate. Always compare loans on the reducing rate.
