A debt-to-income (DTI) ratio calculator shows how much of your gross monthly income goes to debt payments. Lenders use DTI to assess affordability for mortgages, auto loans, and credit cards. The lower your DTI, the easier it is to qualify and the more breathing room you have in your budget.
What DTI includes
DTI is typically calculated as total monthly debt payments divided by gross monthly income. Debt payments include minimum credit card payments, loan payments, and housing costs like mortgage or rent. The calculator helps you see the exact percentage so you can plan improvements.
How to use the calculator
Gather your monthly debt payments and your gross monthly income, then enter them into the calculator. Test scenarios by reducing a payment or increasing income to see how much DTI shifts. If credit cards are a major driver, run the credit card payoff calculator to see how quickly you can reduce those minimums.
What lenders typically look for
Many lenders prefer a DTI below the mid-30 percent range, though exact limits vary by product and lender. A lower DTI can mean better interest rates and higher approval odds. If your DTI is high, focus on the highest-rate debts first using the debt avalanche calculator to reduce payments efficiently.
Next steps
Calculate your current DTI, then create a targeted payoff plan to drop it over the next 6 to 12 months. Even a small reduction can improve your loan options, and the calculator helps you track the impact as your balances fall.
