About Loan Prepayment Calculator

A free, independent tool for understanding how loan prepayment affects interest, tenure and your payoff date - built to be used, not to collect your data.

Why we built this

Most loan calculators online only answer one question - "what's my EMI?" We wanted something that answers the question people actually struggle with: "if I pay extra towards my loan, how much time and money does that actually save me?" That turned out to need a proper month-by-month amortization simulation, not a quick formula, so that's what we built.

The site started as a single home loan prepayment calculator and has since grown to cover personal, car and education loans, a currency converter, and a set of plain-language guides on how prepayment, charges and lender rules actually work.

How the calculations work

Every result on this site comes from a standard month-by-month amortization calculation - the same underlying method lenders use internally - run entirely in your browser using JavaScript. Nothing you enter is sent to a server, logged, or stored anywhere; if you close the tab, the numbers are gone. We do not use AI or estimation shortcuts for the financial math itself - only ordinary, transparent loan-amortization formulas.

That said, every lender applies small details differently (exact interest-application dates, compounding conventions, fees). We're upfront that this tool gives accurate estimates for planning purposes, not a substitute for your lender's official figures - see our disclaimer for the full wording.

What this site is not

• We are not a bank, lender, broker or financial advisor, and we don't arrange loans or take loan applications.
• We don't require an account, login, or any personal or financial information to use the calculators.
• We don't sell your data, because we don't collect any in the first place - see the privacy policy for details.

How this site is funded

The calculators are, and will remain, free to use. The site is supported by display advertising (Google AdSense) and, in the future, may include clearly-labelled links to relevant financial products - we won't list offers we haven't vetted, and ads never appear inside the calculator's input or results area.
