💡 How It Works

28/36 Rule: Housing costs should not exceed 28% of gross income; total debt (including mortgage) should not exceed 36%.
Formula: Monthly Payment = Loan × r(1+r)ⁿ / ((1+r)ⁿ-1), where r = monthly interest rate, n = total number of payments.
Note: Actual loan approval also considers credit score, employment history, and other factors. This is an estimate only.
