EMI Calculator with Prepayment

This calculator leads with the prepayment field, because that is the number most people come here for: how much interest does an extra ₹5,000 or ₹10,000 a month actually save? It opens on a ₹30 lakh loan at 9% for 20 years — replace it with your own numbers and watch the savings banner update as you type.

Extra paid every month on top of the EMI — it goes straight to principal and closes the loan early.

From a free tool to your own software

Software for lenders, NBFCs and loan distributors

Loan officers and DSAs often quote EMIs from spreadsheets that stop matching the lender's own system once processing fees, broken-period interest or a part-prepayment enter the picture. NBFCs, co-operative banks and dealer finance teams need one calculation engine behind the quote, the sanction letter and the repayment schedule, so a borrower hears the same number at every step.

  • Loan origination systems

    Capture applications, collect documents, run eligibility checks and generate sanction letters whose EMI and amortisation schedule come from the same engine that services the loan.

  • Loan management and collections software

    Track disbursals, due dates, part-prepayments and overdues, recalculate schedules when the rate or tenure changes, and send borrowers reminders before each instalment.

  • Borrower self-service apps

    Let customers check their outstanding principal, download statements, request foreclosure figures and see the effect of a prepayment before they call your branch.

  • EMI quote tools for dealers and DSAs

    Give showroom staff and loan agents a branded quote tool that uses your current loan products and charges, and sends each enquiry straight into your lead pipeline.

Who we build this for: NBFCs, co-operative banks, housing finance companies, loan DSAs and vehicle or consumer-durable dealers.

Questions people ask

How does prepayment reduce EMI or tenure?

Two options exist in principle: keep the EMI the same and finish early (reduce tenure), or keep the tenure the same and lower the EMI (reduce EMI). This calculator always applies your extra payment to reduce tenure, because rupee for rupee it saves far more total interest than reducing the EMI does.

Why does reducing tenure save more interest than reducing EMI?

Reducing tenure keeps your extra payment working against the principal every month for the rest of the loan, cutting interest for every remaining period. Reducing EMI instead spreads the same extra amount thinly over a longer remaining term, so less of it goes toward principal early — the compounding math favours tenure reduction.

How much does ₹5,000/month extra save on a ₹30 lakh loan?

It depends on your rate and remaining tenure, but on a 9%, 20-year loan an extra ₹5,000 every month typically closes the loan several years early and saves well over ₹5 lakh in interest. Enter your exact numbers — the savings banner computes it precisely.

Is there a penalty for prepaying my loan?

Floating-rate loans to individuals carry no prepayment penalty under RBI rules — this applies to home loans and most personal/car loans on floating rates. Fixed-rate loans can have charges; check your loan agreement before committing to a plan.

Can I add a one-time lump sum instead of a monthly extra?

This calculator models a fixed monthly extra, which is the more common and more powerful habit — a bonus or maturity payout can be approximated by averaging it into a temporary monthly top-up for the months you have it.

Is my loan and prepayment data private?

Yes — everything is computed in your browser, nothing is uploaded, and the page keeps working offline once loaded.
