How it works

Lenders often cap the share of your income before tax that can go on housing and debt repayments. We take that share of your monthly income, subtract your other debt payments and running costs, and treat what is left as the most you can pay towards a loan each month. We then work out how big a loan that payment repays over your term and add your down payment.

Formula

  • Housing budget = yearly income ÷ 12 × limit % − other debt payments
  • Loan payment = housing budget − other monthly costs
  • Loan = loan payment × (1 − (1 + r)^−n) ÷ r, with r = rate ÷ 12 ÷ 100, n = years × 12
  • Affordable price = loan + down payment

Frequently asked questions

What limit for housing and debts should I use?

Many lenders look for total debt payments of roughly 35% to 45% of income before tax, but rules vary by country and lender. A lower limit leaves more breathing room for savings and surprises. Try a few values to see how sensitive the price is.

Is the affordable price what I should spend?

It is the most the limit allows, not a target. It doesn't count moving costs, repairs, furniture or the purchase taxes and fees that some countries charge. Spending less than the maximum keeps your budget safer if rates or income change.

Why does a higher interest rate lower the price so much?

Your monthly budget stays the same, but at a higher rate more of each payment goes on interest. That leaves less to repay the loan itself, so the loan you can support shrinks, and the home price shrinks with it.

Should I use income before or after tax?

Use income before tax, because lenders usually set these limits against pay before tax. If you prefer to plan from take-home pay, lower the limit to stay on the cautious side.
