Mortgage calculator: monthly payment and real effort
Estimate your monthly mortgage payment, how much you would finance, roughly how much cash you need and what share of your income would go to the payment. Before locking in a payment, it helps to know how much money you need to buy and to review purchase costs in Madrid if you are buying in the capital.

Compare fixed vs mixed mortgageHow to use this mortgage calculator
Enter the property price, the deposit you have available, the estimated interest rate, the mortgage term and your net monthly income. The calculator estimates the monthly payment, the financed amount and the debt-to-income ratio.
The debt-to-income ratio compares the mortgage payment with your net income. If the payment approaches or exceeds 30–35% of your income, the deal may leave little room for expenses, saving, surprises or future rate rises.
The tool is indicative. The final payment depends on the bank offer, interest rate, fees, insurance, product ties and the specific terms of the deal.

Frequently asked questions
Common questions about calculating a mortgage
How is a monthly mortgage payment calculated?
The payment depends on the financed amount, the annual interest rate and the term. A larger loan, a higher rate or a shorter term raises the monthly payment.
What share of income should go to the mortgage?
As a prudent rule, many buyers aim for the mortgage payment not to exceed roughly 30–35% of the household’s net monthly income.
How much cash do I need saved to buy?
On top of the deposit, you need taxes, notary, land registry, admin fees, valuation and an extra cushion for surprises, renovation or furniture.
Does the calculator replace a bank offer?
No. It is an indicative estimate. The real payment depends on the bank offer, interest rate, fees, insurance, product ties and specific terms.
