Loan calculator — monthly payment, interest & payoff
Work out your monthly payment, what the loan really costs, and how much sooner you finish if you overpay each month. Includes a full amortisation schedule you can export.
Runs in your browser — your input is not uploaded to ToolsNow.
Optional — see how much faster the loan clears and what that saves.
Currency & fees
Sets the currency, and how numbers you type are read.
Adds an estimated effective APR to the results.
Calculations are estimates. APR/APRC rules vary (US TILA vs EU Consumer Credit Directive) — always check your lender’s own disclosures.
How to use
- Set the country so amounts display in the right currency and number format.
- Enter amount, yearly rate and term. Use the nominal yearly rate — the tool converts it to a monthly rate itself.
- Add an extra monthly payment to see the shortened term and the interest it saves.
- Add upfront fees to get an estimated effective APR for comparing offers fairly.
Questions
How much difference does an extra monthly payment make?
More than most people expect, because every extra euro goes straight against the principal and stops accruing interest for the remaining term. Enter an amount in the extra field and the tool shows both the shortened term and the interest saved against the contractual schedule.
What does the estimated APR include?
It solves for the rate that equates your upfront fees plus the payment stream to the amount you actually received. Add your arrangement or origination fees to see the true annual cost, which is usually higher than the headline interest rate.
Why does my lender quote a different APR?
Disclosure rules differ: US TILA and the EU Consumer Credit Directive include different fees and use different compounding conventions. Treat this figure as a comparison aid, not a regulatory disclosure.
Can I export the schedule?
Yes. Download CSV gives you every period with its payment, principal, interest and remaining balance, ready for a spreadsheet.
