Mortgage calculator

Calculate your monthly mortgage payment from the home price, the down payment you'll put in, the interest rate and the term. Add your income and we'll also show what share of your salary the payment would take.

How the payment is calculated

The monthly payment uses the standard amortizing-loan formula: you pay the same amount every month, but early on most of it is interest, and over time more of it goes to principal. This calculator applies the nominal annual interest rate divided by 12 to get the monthly rate.

What each result means

The financed amount is the home price minus your down payment — what you're actually borrowing from the bank. Total interest is what you'll pay on top of that over the life of the loan, and the total paid is principal plus interest over the whole term.

How much should the payment be relative to my income?

Most lenders and advisors recommend that your mortgage payment, combined with other debts, stay under 30-35% of your net monthly income. If you enter your income, we'll flag it when your ratio goes above that — it's a general guideline, not a fixed rule, since your own situation may differ.

A simple example

For a €250,000 home with a €50,000 down payment, you'd finance €200,000. At 3% interest over 25 years, the monthly payment is around €948, and you'd pay about €84,500 in interest over the life of the loan.

Frequently asked questions

Should I use the nominal rate or the APR?

Use the nominal interest rate (TIN in Spain), which is what's directly applied to calculate the monthly payment. The APR also folds in fees and costs, so it's usually higher and isn't the figure this formula needs.

What if my mortgage has a variable or mixed rate?

This calculator assumes a fixed rate for the whole term. If your mortgage is variable or mixed, you can still use it to estimate the payment at today's rate, but keep in mind it can change at each review (usually tied to an index like Euribor).

Does this include purchase costs (taxes, notary...)?

No — this calculator covers only the loan itself: payment, interest and principal. If you also want to see taxes, notary costs and whether your savings cover the upfront cost, use the "What home can we afford?" calculator.

Why do I pay so much interest early on?

That's how a standard amortizing loan works: the payment stays constant, but early on most of it is interest on the still-high outstanding balance. As the years go by, that proportion flips toward principal.
