Start with monthly breathing room
This Spain mortgage affordability calculator works backwards from household cash flow. Net monthly income minus living expenses, debt payments, ownership costs and your chosen buffer produces an illustrative mortgage‑payment budget. The tool converts that amount into a loan using the planning rate and selected term, then adds usable deposit funds.
A household example
Suppose monthly net income is €3,400, living expenses €1,450, debt payments €250, ownership costs €300 and the desired buffer €400. That leaves €1,000 for an assessed mortgage payment. Entering a 3% rate plus a two‑percentage‑point stress buffer tests the loan at 5%. Over 25 years, €1,000 a month supports approximately €171,060 of borrowing under those assumptions.
Check completion cash separately
Usable deposit equals savings minus the reserve and entered buying costs, floored at zero. The headline property budget can remain positive even when savings do not cover costs and the reserve. Use the target‑property section to check any cash shortfall rather than relying on the headline alone.
Do not confuse two income measures
The monthly budget uses take‑home income. The debt‑to‑income indicator divides debt balances by gross annual income and displays a multiple. It is not the share of monthly income spent on repayments. Adjusting its marker affects warnings, not the loan calculated from available cash flow. Neither marker represents a universal Spanish approval rule.
Build a Spain‑specific ownership budget
Enter IBI, home insurance, community fees and maintenance as monthly amounts on this page. Add transaction‑specific buying taxes and expenses separately. These costs do not update automatically when the target price changes. Finally, compare the target’s stressed repayment and required cash with your available resources; lender valuation and affordability assessment remain separate steps.
