Home Loan Prepayment Calculator

Compare interest and repayment time using your current loan balance. Start with three loan details; add a prepayment amount to compare.

The example inputs are ready. Select Calculate or replace them with your figures.

How the comparison works

The regular EMI is calculated from your balance, monthly rate and remaining term. The prepayment illustration keeps that EMI unchanged and reduces repayment time. Each month, interest is added and the EMI plus your extra payment is deducted; the final payment is capped at the amount owed.

EMI = P × r × (1+r)n ÷ ((1+r)n − 1), where r is the annual percentage divided by 1,200. At a zero rate, EMI is P ÷ n.

Check these assumptions

The model assumes a constant rate and monthly interest, with no prepayment fees or tax effects. Your lender may use daily accrual, change the rate, restrict prepayments or reduce the EMI instead of the term. Compare with your lender’s statement. The result illustrates arithmetic and does not decide whether prepayment is suitable.
