Formula

Maximum housing payment = 28% of gross monthly income, capped so total debt (including housing) stays under 36% of gross monthly income.

Example

An income of $90,000/year allows a housing payment up to about $2,100/month under the 28% rule. Subtracting $400 in other debts, the loan is sized to a payment that keeps total debt near 36% of income.

Frequently Asked Questions

What is the 28/36 rule?

A common lending guideline: housing costs should not exceed 28 percent of gross monthly income, and total debt payments, including housing, should not exceed 36 percent.

Will lenders always use these exact numbers?

No, some loan programs allow higher debt-to-income ratios. This calculator gives a conservative, widely used benchmark, not a loan approval guarantee.
