How Loan Prepayment Calculator is Calculated

This calculator uses the formula: Interest Saved = Total Interest (before) − Total Interest (after prepayment). Where New Principal = Outstanding − Lump Sum ; EMI remains same, tenure reduces. Lump-sum prepayment reduces principal, saving significant interest over remaining tenure. All calculations run entirely in your browser — no data is transmitted to any server.

Frequently Asked Questions

Is it better to reduce EMI or tenure when prepaying?

Reducing tenure almost always saves more interest in the long run. Reducing EMI gives more monthly cash flow. If you can afford the same EMI, always choose tenure reduction.

Are there prepayment penalties on home loans?

RBI prohibits prepayment penalties on floating-rate home loans. Fixed-rate loans may have 2–3% charges. Personal loans typically charge 2–5% foreclosure fees.

When is the best time to prepay a loan?

Prepay early in the loan tenure when interest component is highest. After the halfway point, most of your EMI goes toward principal and prepayment saves less interest.
