Mortgage calculator
Work out the monthly payment on a repayment mortgage, in any country and any currency, from your loan amount, the interest rate you have been offered and the term.
The result is an estimate. It is not an offer of credit and not financial advice. A lender decides what it will lend.
Monthly payment
1,169.18
Total paid: 350,754.02
Total interest: 150,754.02
Totals use the exact monthly payment. The payment shown is rounded to 2 decimal places.
How it is calculated
- You enter:
- the loan amount;
- the annual interest rate (your own rate: we do not supply rates);
- the term in years;
- optionally, a currency. It changes only how amounts are written; nothing is converted.
- Monthly payment M = P x r(1 + r)^n / ((1 + r)^n - 1).
- P is the loan amount.
- r is the annual rate / 12 / 100.
- n is the number of monthly payments (years x 12).
- At a 0% rate, M = P / n.
- The page also shows the total paid and the total interest.
- Not included: taxes, insurance and fees. The rate is assumed fixed for the whole term.
This is the standard annuity formula. We state it as mathematics; it is not quoted from any regulator.
Official lending rules by country (optional boxes)
Choose a country to see what its regulators say. These are rules for LENDERS. They are not a decision on your loan. If your numbers go past a rule, the page shows a flag and the rule. It never shows "approved" or "refused".
United Kingdom
- Interest-rate check (MCOB 11.6.18): if your rate is fixed for less than five years (and not for the whole term), the lender must allow for rates to rise. The FCA rule (MCOB 11.6.18) says that "a mortgage lender must assume that interest rates will rise by a minimum of 1% over that period" (the first five years).
- Loan-to-income: across the market, the FPC recommends that loans "at loan-to-income ratios (LTIs) at or greater than 4.5" should not "exceed 15% of total new residential mortgages" (FPC recommendation 25/Q2/1, 27 June 2025).
- It caps the share of such loans across all lenders, not any one borrower's loan. If you enter your income, the page flags a loan of 4.5 times your income or more.
- What is not there: no official cap on loan-to-value or on debt-to-income.

Germany, Spain, Italy
- No official limit. These countries have no binding limit on loan-to-value, loan-to-income or debt service for home loans.
- In Germany and Spain the law requires lenders to assess the borrower's ability to repay (BGB ss.505a/505b; Ley 5/2019 art. 11), with no numeric threshold.
- For Italy, the general creditworthiness duty was not read for this page.
- Germany's regulator has the power to set limits "bei Bedarf" (when needed) and has not used it. That last point is our reading of the absence of any measure; no page says it in those words.
- Sources:
- Spain's "no limit" rests on the 2024 report: nothing newer was verified.
There is no official limit here, so there is nothing to flag.
