About this calculator

Bonuses and maturity proceeds often tempt prepayment. Seeing approximate interest saved helps you decide whether to cut the loan or invest the cash.

Confirm foreclosure charges and part-prepayment rules with your financier before transferring funds.

Formula summary

Compare interest on outstanding schedule vs shortened tenure after reducing principal (EMI held constant).

Assumptions

  • Reducing-balance EMI formula; processing fees and insurance add-ons not included unless you add them to the loan.
  • Interest rates vary by bank, credit score and promotional offers.
  • Outputs are estimated / indicative — not a sanction letter.
  • Prepayment fees and lock-in rules are not deducted — check your agreement.

FAQs

Should I reduce EMI or tenure?

This model keeps EMI and shortens tenure, which usually maximises interest saved. Ask your bank which option they offer in-app.

Is prepaying always best?

Compare the interest saved with returns you could earn elsewhere and with your emergency-fund needs. Numbers alone are not advice.
