Introducing the Mortgage Prepayment Calculator — See What Paying Extra Saves

Paying extra on a home loan is one of the highest-return, lowest-risk uses of spare cash — but the size of the benefit is hard to picture. The new Mortgage Prepayment Calculator makes it concrete: a modest extra each month can cut years off your loan and save lakhs in interest.

What it does

• Interest saved and months reduced — the headline benefit, instantly.
• Two modes — a fixed monthly extra, or a one-time lump sum at a month you choose.
• Reduce-tenure strategy — keeps your EMI fixed for maximum interest savings.
• Before-and-after comparison — see interest with and without prepayment side by side.
• Accurate simulation — a true month-by-month amortisation, no shortcuts.

Why it matters

Loan interest is front-loaded, so prepaying early removes the most future interest. The big question — prepay or invest? — comes down to comparing your loan rate against expected returns. Our guide to mortgage prepayment walks through the trade-offs, and the mortgage calculator helps you size the original loan first.

Free, and private

The Mortgage Prepayment Calculator is free and runs entirely in your browser — nothing you enter is uploaded or stored. A future Pro tier is planned for full prepayment scheduling and export, but the core calculator stays free forever.
