Repayment Calculator — Calculations & Slabs for FY 2026-27

A repayment calculator helps you determine the exact monthly payment required to fully pay off a loan or credit card balance within a specific target timeframe. By adjusting the target months or years, you can see how different payoff timelines affect your monthly budget and the total interest paid.

A higher interest rate means a larger portion of your monthly payment is spent covering interest charges rather than reducing your principal balance. To pay off the loan in the same timeframe, your monthly payment must increase to offset the interest. Lower interest rates accelerate principal reduction.

For most credit cards and standard personal loans, yes. Making payments above the minimum required amount goes directly toward reducing your principal balance. Since interest is calculated based on this remaining balance, paying it down faster reduces the total interest you accrue. Always check for prepayment penalties on auto or mortgage loans.

Increasing your monthly payment by even 10% has a compounding positive effect. The extra cash goes directly toward principal paydown. This shortens your payoff term and reduces the total interest paid. The earlier you start making extra payments, the greater the interest savings.

A fixed payment (which this calculator determines) stays constant every month until the debt is cleared. A minimum payment (typically 2% to 3% of your remaining balance) decreases as your balance drops. Paying only the minimum results in an extremely long payoff timeline and maximum interest cost.
