What Is Debt-to-Income Ratio?

Your debt-to-income (DTI) ratio is the percentage of your gross monthly income that goes toward monthly debt payments. Lenders use it to assess your ability to manage loan repayments.

Front-end DTI (housing ratio): Only your proposed housing payment ÷ gross income. Most lenders want this below 28%.

Back-end DTI (total debt ratio): All monthly debt payments (housing + car + student loans + credit cards + other) ÷ gross income. Most conventional loans require this below 43%.

Why It Matters for Renovation Projects

Planning a kitchen remodel, bathroom renovation, deck, or home addition? If you're financing the project — through a home equity loan, cash-out refinance, or construction loan — lenders will calculate your DTI before approving. Knowing your number in advance helps you:

  • Shop for financing with confidence
  • Know your maximum loan amount
  • Avoid surprises during underwriting
  • Compare offers from multiple lenders
