Frequently asked questions
When is the best time to prepay a home loan?+
Earlier in the tenure, because more of each EMI is interest. A payment in year 2 usually saves far more than the same payment in year 15.
Should I reduce EMI or tenure after home loan prepayment?+
Reduce tenure if you can afford the current EMI. Reduce EMI only when monthly cashflow relief is more important than total savings.
How often should I prepay?+
A common strategy is one extra EMI per year plus a fixed share of bonuses, especially during the first half of the loan.
