28/36 Rule Calculator
The 28/36 rule is a classic mortgage-lending guideline. Enter your income and existing debts to see your suggested housing and total debt limits.
What is the 28/36 rule?
The 28/36 rule is a widely used guideline lenders reference when evaluating mortgage affordability. It suggests that your monthly housing costs (principal, interest, taxes, and insurance) should not exceed 28% of your gross monthly income, and your total monthly debt payments, including housing, should not exceed 36%.
How this calculator works
Enter your gross monthly income and any other recurring monthly debt payments (car loans, credit cards, student loans). The calculator shows the 28% housing cap, the 36% total debt cap, and how much room remains for housing once your other debts are subtracted from the 36% limit.
This is a general planning guideline, not a lending decision. Actual mortgage approval depends on your lender’s specific criteria, credit profile, and loan program.
