How this works

Every dollar above your minimum EMI goes directly to principal. Since interest is calculated monthly on whatever balance remains, a smaller balance means less interest accrues — and a bigger share of next month's payment goes to principal again. That's the compounding effect of prepayments.

On a 30-year mortgage, your early payments are mostly interest. Strategies like this one accelerate you past the interest-heavy years. Result: $233,217 stays with you instead of the bank, and you finish 15y 0mo sooner.
