How to use
Step 1
Enter your loan amount, annual interest rate, and repayment tenure in years.
Step 2
Enable any combination of advanced repayment strategies: extra EMI per year, yearly lump-sum prepayment, one-time timed prepayment, or step-up EMI.
Step 3
Adjust each strategy to reflect realistic amounts and timings based on your income or bonus schedule.
Step 4
Review the revised payoff month, total interest, interest saved, and months saved to compare strategies.
Step 5
Use the charts and yearly amortization breakdown to decide the most practical and cost-effective approach.
Formula and method
This calculator uses the shared advanced loan engine to model all major prepayment strategies simultaneously — extra EMI, yearly lump-sum, one-time prepayment, and step-up EMI — so you can compare their combined or individual impact on interest cost and payoff timing.
Example calculation
These examples show how combining multiple prepayment strategies produces greater savings than any single strategy applied alone, and how adjusting timing and amount changes the overall outcome.
Example 1
A home loan of 5,000,000 at 8.5% for 20 years can be paid off several years earlier by combining yearly extra EMI with a one-time mid-tenure lump-sum prepayment.
Example 2
Comparing extra EMI alone versus yearly lump-sum alone helps identify which approach gives more savings for the same total cash outflow.
Example 3
A step-up EMI strategy combined with a single bonus-year prepayment can produce a larger combined reduction in interest than either method on its own.
Loan Prepayment Calculator FAQ
What is the difference between part prepayment and foreclosure?
Part prepayment reduces the outstanding principal while keeping the loan active. Foreclosure means paying off the entire remaining balance at once to close the loan. This calculator focuses on part prepayment strategies.
Which prepayment strategy saves the most interest?
It depends on the timing and amounts. Generally, reducing principal earlier in the loan tenure saves more interest because future EMIs carry more interest on a larger balance. Use this tool to compare strategies side by side.
Should I prepay my loan or invest the surplus instead?
This depends on your loan interest rate versus expected investment returns, tax deductions available, and risk tolerance. This calculator shows the guaranteed savings from prepayment so you can compare that against investment options.
Can I test multiple strategies at once?
Yes. The workspace supports enabling extra EMI, yearly lump-sum, one-time prepayment, and step-up EMI simultaneously so you can model a combined repayment approach in a single run.
What happens to my EMI after a prepayment?
In this model, the EMI stays fixed and the loan closes earlier than the original schedule. Some lenders allow you to reduce EMI instead, but shortening the tenure typically produces more interest savings.
Does this work for home loans, car loans, and personal loans?
Yes. The underlying calculation supports any loan type as long as you know the principal amount, annual interest rate, and repayment tenure. Adjust the inputs to match your specific loan.
