Loan Prepayment Calculator
Compare lower EMI versus shorter tenure after making a lump-sum prepayment.
Estimates assume the same rate throughout and no prepayment charge. Confirm the lender’s recalculation method.
How to compare loan prepayment options
- Enter your loan details. Add the original loan, interest rate, tenure and EMIs already paid.
- Enter the prepayment. Add the proposed lump-sum amount.
- Compare the outcomes. See keeping the tenure with a lower EMI against keeping the EMI with a shorter tenure.
What happens to your data
The comparison runs entirely in your browser using standard amortization formulas — your loan details are never sent to a server.

Frequently asked questions
Is my loan data uploaded anywhere?
No — the comparison runs entirely in your browser.
Which option saves more interest — lower EMI or shorter tenure?
Generally, keeping the EMI the same and shortening the tenure saves more total interest; the comparison shows the actual numbers for your specific loan.
Are these exact figures?
No — check your lender's foreclosure charges, prepayment rules and recalculation method before acting. This tool gives estimates for comparison.
Does it account for prepayment penalties?
No — enter the loan and prepayment figures as-is, and factor in any lender fees or penalties separately.
What does "EMIs already paid" do?
It's used to estimate your current outstanding balance before applying the prepayment.
