Understanding Debt-to-Income Ratio

Your debt-to-income ratio (DTI) is a key factor lenders use to determine how much you can afford to borrow. It compares your monthly debt payments to your monthly gross income.

Front-End vs. Back-End DTI

  • Front-End DTI: Housing costs (mortgage, taxes, insurance) divided by gross income
  • Back-End DTI: All debt payments (housing + other debts) divided by gross income
  • Formula: DTI = (Monthly Debt Payments ÷ Monthly Gross Income) × 100

What Counts as Debt?

  • Housing Costs: Mortgage principal, interest, taxes, insurance, HOA fees
  • Installment Loans: Car loans, student loans, personal loans
  • Revolving Debt: Credit card minimum payments
  • Other Obligations: Alimony, child support

Improving Your DTI

  • Pay Down Debt: Reduce balances on credit cards and loans
  • Increase Income: Additional income can improve your ratio
  • Larger Down Payment: Reduces mortgage amount and monthly payment
  • Shop Around: Different lenders have different DTI requirements
  • Debt Consolidation: May lower monthly payments

Important: DTI is just one factor lenders consider. Your credit score, employment stability, and down payment also play important roles in loan approval.
