FAQ
- What is the 28/36 rule?
- A common lending guideline: your housing payment should not exceed 28% of gross monthly income (the front-end ratio), and your total debt payments — housing plus other debts — should not exceed 36% of gross monthly income (the back-end ratio). The calculator uses the lower of the two limits.
- How is the front-end ratio used?
- The front-end ratio caps the mortgage payment at 28% of gross monthly income (annual income ÷ 12 × 0.28), independent of your other debts.
- How is the back-end ratio used?
- The back-end ratio caps total debt at 36% of gross monthly income (annual income ÷ 12 × 0.36). Your existing monthly debts are subtracted from that limit, and the remainder is what is left for the mortgage payment.
