Income To Mortgage Ratio Calculator
Buying a home is one of the biggest financial decisions you’ll make. Understanding how your income relates to your mortgage payments is key to managing your finances responsibly. Our Income to Mortgage Ratio Calculator helps you quickly determine if your mortgage payments are affordable and how your total debts affect your financial health.
This calculator evaluates both your front-end ratio (housing costs compared to income) and back-end ratio (all monthly debts compared to income). By using this tool, you’ll gain a clear picture of your financial situation, avoid overborrowing, and make smarter housing decisions.
What is an Income-to-Mortgage Ratio?
The Income-to-Mortgage Ratio measures the portion of your income allocated to mortgage payments and overall debt. There are two key metrics:
- Front-End Ratio (Housing Ratio):
The percentage of your monthly income used for mortgage payments, property taxes, and insurance. Ideally, this should not exceed 28–33% of your income. - Back-End Ratio (Total Debt Ratio):
The percentage of your monthly income that goes toward all debt obligations, including mortgage, credit cards, car loans, and other debts. A healthy back-end ratio is typically below 36–43%.
Calculating these ratios helps lenders assess your ability to repay a mortgage and helps you avoid financial strain.

Example of Using the Calculator
Scenario:
- Annual income: $75,000
- Monthly mortgage: $1,800
- Other debts: $300
Calculations:
- Monthly income = $75,000 ÷ 12 = $6,250
- Front-End Ratio = $1,800 ÷ $6,250 × 100 = 28.8%
- Back-End Ratio = ($1,800 + $300) ÷ $6,250 × 100 = 33.6%
Result:
- Front-End Ratio: 28.8%
- Back-End Ratio: 33.6%
