Frequently Asked Questions
How does a prepayment save me money? expand_more
A prepayment reduces your outstanding principal directly. Since interest is charged on the remaining balance, a lower balance means less interest accrues every month afterward, and the loan finishes sooner.
Does prepaying reduce my EMI or my tenure? expand_more
This [Loan Prepayment Calculator](/tools/loan-prepayment-calculator/) keeps your monthly EMI the same and shortens the loan tenure, which maximizes interest savings. Some lenders instead lower the EMI and keep the tenure—check your loan terms.
Is it better to prepay earlier or later? expand_more
Earlier prepayments save far more interest because more of the loan term remains for that lower balance to compound against. Try different "prepay after" values to see the effect.
Should I prepay or invest the money instead? expand_more
Compare your loan rate to the after-tax return you could earn investing. If your loan rate is higher than your expected investment return, prepaying usually wins. Use our [Interest Calculator](/tools/interest-calculator/) to estimate investment growth.
Are prepayment penalties included? expand_more
No. Some loans charge a prepayment fee. This calculator shows gross interest savings, so subtract any penalty your lender charges to get your net benefit.
