Mortgage Payment Calculator
Enter the property price, your down payment, the interest rate and the loan term — the calculator shows the monthly payment of an annuity mortgage (the standard structure in most of Europe) and how much interest you pay over the whole loan.
How the payment is calculated
An annuity loan has a fixed monthly payment computed as M = L × r / (1 − (1 + r)−n), where L is the loan amount, r the monthly interest rate and n the number of months. Early payments are mostly interest; over time the balance shifts toward principal.
Fixed or variable rate?
European mortgage markets differ sharply by country: long fixed rates dominate in France, Germany and the Netherlands, while Euribor-linked variable rates are the norm in Finland, Spain and much of Southern Europe. With a variable rate, rerun this calculator at 2–3 percentage points above today's rate — if that payment would break your budget, the loan is too large or you need rate protection (a cap, or fixing part of the loan).
What lenders look at
Banks typically want housing costs below roughly 30–40% of net income and apply their own stress-test rate, which is why the affordable loan is often smaller than this calculator alone suggests. A larger down payment lowers both the rate you're offered and any loan-to-value–based fees. If buying is still years away, our savings goal calculator shows the monthly saving needed for the down payment.
A worked example: what one percentage point costs
Take a €200,000 loan over 25 years. At 3.5% the monthly payment is about €1,001 and lifetime interest about €100,400. At 4.5% the payment rises to €1,112 — €111 more per month, which sounds manageable — but lifetime interest jumps to about €133,500. One percentage point cost €33,000. This is why comparing mortgage offers from several banks, and negotiating the margin on a Euribor-linked loan, is some of the best-paid work you will ever do per hour spent.
Frequently asked questions
Annuity, fixed-equal-principal or interest-only?
This calculator models the annuity loan (fixed total payment), the most common structure in Europe. The equal-principal alternative starts with higher payments that fall over time and costs slightly less in total interest. Interest-only periods lower the payment now but the principal doesn't shrink — the cost simply moves into your future.
How big a down payment do I need?
Typically 5–20% of the price depending on country and lender, and a larger one earns a better rate. Saving toward it is a classic use of the savings goal calculator.
