How does home loan prepayment save money?

In a standard reducing-balance loan, interest is calculated daily on the outstanding principal. By paying an extra lump sum, you immediately reduce this principal, meaning all future interest calculations are on a smaller amount. This creates a compounding effect that drastically reduces your loan tenure.

Is it better to prepay monthly or annually?

Mathematically, the earlier you pay, the better. Therefore, increasing your monthly EMI by 10% is mathematically slightly more efficient than waiting 12 months to pay a lump sum. However, a yearly bonus lump sum is often more practical for salaried individuals.

Why Prepayment works like Magic

In a standard reducing-balance loan (like an Indian Home Loan), your initial EMIs consist almost entirely of interest payments. By paying even a small extra amount directly towards the principal, you instantly eliminate the compound interest that principal would have generated over the next 20 years. This mathematically causes the loan tenure to collapse exponentially.
