What Is Debt-to-Income Ratio, and Why Does It Matter

1. DTI Measures How Much of Your Income Goes to Debt

Your debt-to-income ratio is the percentage of your gross monthly income (before taxes) that goes toward paying your debts. That includes:

  • Student loans
  • Auto loans
  • Credit card payments
  • Personal loans
  • And your future mortgage payment

So if you earn $5,000 a month and $2,000 goes to debt, your DTI is 40%. The lower your DTI, the stronger your financial position looks to a lender.

2. Lenders Use DTI to Decide How Much You Can Borrow

DTI tells lenders how easily you’ll be able to afford your monthly mortgage payment on top of your existing obligations. A high DTI can raise red flags, even if your credit score is solid. Most mortgage programs require your DTI to be below 43%, though some loans allow exceptions with strong compensating factors.

3. Lowering Your DTI Boosts Your Buying Power

Want to qualify for more home—or just get approved faster? Start by:

  • Paying down credit cards
  • Avoiding new debts before applying
  • Increasing your income (even temporarily) to shift the ratio

Even small changes can make a big difference. And the best part? Knowing your DTI helps you shop smart and stay in control.
