DTI Calculator: Debt-to-Income Ratio for Loans & Mortgages
Calculate your debt-to-income ratio, the number lenders use to decide whether you can afford a new loan. Enter your gross monthly income and your monthly debt payments to see your front-end (housing) and back-end (total debt) ratios. Example: $6,000 of monthly income with $1,500 of housing cost and $600 of other debt gives a back-end DTI of 35%, which most lenders consider good.
Before taxes. Include all regular income.
Include property tax, insurance and HOA for a mortgage.
Personal loans, child support, alimony.

How to use the Debt-to-Income (DTI) Ratio Calculator
- Enter your gross (pre-tax) monthly income.
- Add your monthly housing payment: rent, or mortgage principal, interest, taxes and insurance.
- Add your car, student loan, credit card minimum and other monthly debt payments.
- Press Calculate to see your front-end and back-end DTI, a rating, and how much new debt you could add at 36% and 43%.
Formula and method
DTI = Total monthly debt payments ÷ Gross monthly income × 100
Do not count everyday expenses such as groceries, utilities or insurance premiums. Example: $2,100 of debt payments on $6,000 of income = 2,100 / 6,000 = 35%.
Frequently asked questions
What is a good debt-to-income ratio?
Many lenders prefer a back-end DTI of 36% or less, with no more than 28% going to housing. Up to 43% is a common limit for mortgage approval.
What counts as debt in DTI?
Rent or mortgage, auto loans, student loans, credit card minimum payments, personal loans, and court-ordered payments. Utilities, food and insurance are not counted.
How can I lower my DTI?
Pay down balances, avoid new debt, refinance to a lower payment, or increase your income. Paying off a small loan entirely removes its whole monthly payment from the ratio.
Does DTI affect my credit score?
No. Credit bureaus do not see your income, so DTI is not part of your score, but lenders weigh it alongside your score.
