Frequently Asked Questions
How much interest do I save by prepaying my home loan? +
Prepayment savings depend on loan size, rate, and timing. Prepaying 10% of a ₹50L home loan at 8.5% after 1 year can save ₹5–8 lakh in interest and cut 3–5 years off a 20-year loan. The earlier you prepay, the more you save because interest is front-loaded. Use the calculator above for your exact numbers.
Should I reduce tenure or EMI when prepaying? +
Reduce Tenure is almost always better — the same EMI clears debt faster and saves the most interest. Reduce EMI gives immediate cash-flow relief but saves less total interest. Choose Reduce EMI only if your monthly budget is genuinely tight. If you can afford the current EMI, always choose Reduce Tenure.
Is prepayment better than investing the money? +
Compare after-tax returns. Prepaying a home loan at 8.5% = guaranteed 8.5% risk-free return (or higher pre-tax equivalent with Sec 24b benefit in the 30% slab). If you can reliably earn more after-tax elsewhere, invest. Personal loans at 15–20% should always be prepaid first — no investment reliably beats that net return.
When is the best time to make a prepayment? +
The earlier the better. Interest is front-loaded in reducing-balance loans, so prepaying in Year 1–3 saves far more than the same amount in Year 10. Check your loan's lock-in period (typically 6–12 months) and prepayment penalty clause first. After the lock-in, start prepaying whenever you have surplus funds.
