Loan payoff calculator

Monthly payment, total interest and the real payoff date — plus the part most free calculators hide: every single month of the schedule, laid out in full.

Annuity or linear
Full amortisation table
Extra-payment comparison
Nothing leaves your browser

Loan amount In euros. What you borrowed, before any repayments.

Annual interest rate Per cent per year. Enter 6.9 for 6.9%.

Term in months 1 to 600. Sixty months is five years.

First payment date Used to date each row and work out the payoff month.

Repayment method Annuity is the usual consumer loan. Linear is common for Dutch mortgages.

How the rate is quoted EU consumer credit is advertised as an effective rate. Mortgages are usually quoted nominally.

Extra payment each month (optional) Paid on top of the scheduled amount and applied straight to the principal. Set it to 0 to ignore it.

Nothing you type here is collected or transmitted. The whole calculation runs in this page, in your browser. There is no form submission, no request to a server and no storage of your figures — close the tab and they are gone.

The whole thing

Every month of the schedule.

This is the table most calculators keep behind a sign-up. Watch the interest column shrink and the principal column grow — that crossover is the point of the whole exercise.

A €300,000 annuity at 4.50% over 30 years. Interest (dashed) falls, principal (solid) rises, and they cross at month 176 — the month more of your payment starts going to you than to the bank. A five-year loan never crosses: the maths needs a long term.

Under the bonnet

How the numbers are worked out.

Annuity

Every month you pay the same total. Interest is charged on whatever is still outstanding, and the rest of the payment reduces the balance. Early on, most of the payment is interest; later, most of it is principal. The payment itself comes from the standard annuity formula, solving for the amount that brings the balance to zero in exactly the term you set.

Linear

You repay the same slice of principal every month — the loan amount divided by the term — and pay interest on the balance on top. The first payment is the largest and every payment after it is smaller. You pay less interest overall than with an annuity, but the early months cost more.

Effective versus nominal rates

The same headline percentage can mean two different monthly rates, and the difference is real money. An effective annual rate compounds: the monthly rate is the twelfth root of the year, so 6.9% becomes about 0.5576% a month. A nominal rate is simply divided by twelve, giving 0.575%. EU consumer credit has to be advertised as an effective rate, which is why that is the default here. Mortgages are usually quoted nominally. Check your loan agreement — it says which one applies.

Extra payments

An extra amount is added to each month's payment and goes entirely against the principal. Because interest is charged on a smaller balance from the next month onwards, the saving compounds. The comparison figures above are this schedule measured against the identical loan with no extra payment.

What this calculator does not model

Arrangement fees, insurance bundled into the payment, early-repayment penalties, variable rates and payment holidays are all left out. A balloon or residual payment at the end is left out too — the CroSum app handles residuals, this page does not. Daily interest accrual is not modelled here either; the calculation assumes monthly periods.

Questions

Reasonable things to ask.

Why does my bank's figure differ by a few cents?

Almost always rounding, or the rate convention. Lenders round each instalment to the cent and some round the final one differently; over sixty months that drifts a little. If the gap is euros rather than cents, try switching between the effective and nominal rate settings — that is usually the culprit.

Should I overpay my loan or save the money instead?

That depends on your interest rate, your savings rate, whether your agreement allows penalty-free overpayment, and whether you have an emergency buffer. This page shows you what overpaying does to this loan — it cannot tell you whether that is the right call for you. Read your loan agreement, and speak to someone qualified if the sum is large.

Is my data saved anywhere?

No. The figures live in the page while it is open and nowhere else. There is no analytics on this page, no form submission and no request to any server once the page has loaded.

What if I have several loans?

This page handles one at a time. The CroSum app tracks them together, alongside your income, budgets and savings, so you can see what all of them cost you in a given month rather than one in isolation.

This is the same calculation CroSum runs on your phone.

The formulas on this page are the ones in the app's loan engine, deliberately kept identical so the two never disagree. The difference is that the app remembers the loan. It tracks the payments you actually make, updates the balance, folds the monthly cost into your budget and your Safe to Spend figure, and tells you what is left over — instead of asking you to retype everything each time you wonder.

One loan is free. Premium removes the limit and adds the twelve-month planner, so you can see what taking on another one would do before you sign.
