Debt-to-Income Ratio Calculator

Calculate your debt-to-income ratio (DTI) to understand your borrowing capacity and financial health.

What is Debt-to-Income Ratio Calculator?

The debt-to-income ratio (DTI) compares your total monthly debt obligations to your gross monthly income. Lenders use it as a key measure of your ability to manage monthly payments and repay new debt. A lower DTI signals financial health; a higher DTI indicates potential overextension that may limit loan approvals.

How to use

  1. 1 Enter your monthly housing payment (rent or mortgage including taxes and insurance).
  2. 2 Enter all other monthly debt payments — car loans, student loans, credit card minimums.
  3. 3 Enter your gross monthly income (before taxes).
  4. 4 Your overall DTI, front-end ratio (housing only), and a status rating appear instantly.
  5. 5 Work toward reducing your DTI before applying for a major loan.

Formula

DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100. Front-End Ratio = (Housing Payment ÷ Gross Monthly Income) × 100.

Example calculation

Monthly debts: mortgage $1,500, car $400, student loans $300, credit cards $200 = $2,400 total. Income: $7,000/month. DTI = 34.3% (Good). Front-end = 21.4%.

Frequently asked questions

What is a good DTI ratio?

Under 36% is generally considered good. 36%–43% is acceptable for most mortgages. 44%–50% is a warning zone — some lenders will decline. Above 50% makes most loans very difficult to obtain.

What is the front-end ratio?

The front-end ratio (or housing ratio) measures only housing costs as a percentage of income. Most mortgage lenders want this under 28%. FHA loans allow up to 31%. Staying under 28% leaves room for other debts.

Does DTI affect my credit score?

DTI itself is not factored into credit scores — credit utilization is. However, high DTI often correlates with high utilization and payment stress. Lenders check both your credit score and DTI independently.

How can I improve my DTI?

Pay down existing debts (especially high-balance installment loans), avoid taking on new debt before applying for a loan, or increase your income. Even paying off one small loan can meaningfully shift your ratio.

What debts are included in DTI?

Recurring monthly obligations: mortgage/rent, car payments, student loans, minimum credit card payments, personal loan payments, child support, and alimony. Utilities, groceries, and insurance are typically excluded.
