Calculateur de Capacité d'Achat Immobilier

Le logement le plus cher que vos revenus peuvent financer.

Introduction

Home Affordability Calculator — The most expensive home your income can support. Enter Gross annual income (before tax), Other monthly debt payments (cards, car, student loans), Mortgage interest rate (% per year), Term (years), Down payment to get an instant, accurate result.

Formule

Rule-of-thumb estimate. Maximum principal-and-interest payment = the smaller of (a) 28% of gross monthly income and (b) 36% of gross monthly income minus your other monthly debt payments. The maximum loan is that payment converted with the standard annuity factor (1 − (1+r)⁻ⁿ) / r, and the estimated maximum home price adds your down payment. If your other debts already use the whole 36%, no payment is available and the calculator says so.

Questions Fréquentes

Is 28% / 36% a lender rule?
No. It is a commonly cited guideline (housing at most 28% of gross income, housing plus other debts at most 36%). Lenders and loan programs use different limits and also look at credit, savings and the property, so treat the result as a rough estimate, not a loan decision.
Does this include taxes and insurance?
No. The payment is principal and interest only. Property tax, home insurance, PMI and HOA dues are excluded, and they would reduce the price you can truly afford.
What inputs does the Home Affordability Calculator need?
You'll need to provide: Gross annual income (before tax), Other monthly debt payments (cards, car, student loans), Mortgage interest rate (% per year), Term (years), Down payment. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
