What Is Debt-to-Income Ratio?

The key metric lenders use to assess your borrowing capacity

Your debt-to-income (DTI) ratio compares your total monthly debt payments to your gross monthly income. Lenders use it to evaluate your ability to manage monthly payments and repay borrowed money.

Front-End DTI

Housing expenses only (mortgage, tax, insurance, HOA, PMI/MIP) divided by gross income. Target: under 28%.

Back-End DTI

All monthly debts (housing + credit cards, loans, etc.) divided by gross income. Target: under 36%.

How DTI Is Calculated

The formula and a worked example

Front-End DTI

Front-End DTI (%) = (Housing Expenses ÷ Gross Monthly Income) × 100

Back-End DTI

Back-End DTI (%) = (Total Monthly Debts ÷ Gross Monthly Income) × 100

Example

  • Gross monthly income: $6,000
  • Housing expenses: $1,500 (mortgage + tax + insurance + PMI)
  • Other debts: $800 (credit cards + student loans + auto)
  • Front-End DTI: $1,500 ÷ $6,000 = 25.0%
  • Back-End DTI: $2,300 ÷ $6,000 = 38.3%

Note: DTI uses gross income (before taxes), not take-home pay.

DTI Ranges & What They Mean

How lenders interpret your back-end DTI ratio

0% – 20%Excellent

Very low risk. Strongest approval odds and best interest rates.

21% – 35%Good

Healthy balance. Qualifies for most loan programs.

36% – 43%Manageable

Approaching limits. FHA and VA may still approve.

44% – 50%High

Difficult to qualify. Strong compensating factors needed.

50%+Very High

Most lenders will not approve. Debt reduction critical.

How to Lower Your DTI Ratio

Actionable strategies to improve your borrowing power

Pay down high-payment debts

Eliminating a $300/mo car payment immediately drops your DTI by that amount.

Increase your income

A raise, side income, or adding a co-borrower directly lowers the ratio.

Avoid new debts

Don’t open new credit cards or take loans before a mortgage application.

Consider a smaller home

A lower mortgage payment reduces your front-end DTI immediately.

Refinance existing debts

Extending loan terms lowers monthly payments, though total interest rises.

Add a co-borrower

A co-borrower’s income counts toward the DTI denominator.
