Debt-to-income (DTI) is the percentage of your gross monthly income that goes toward required monthly debt payments. Mortgage lenders use it to estimate how much monthly debt you can reasonably handle.
DTI = total monthly debt payments / gross monthly income
Use income before taxes and payroll deductions. If you earn a salary, annual salary / 12 gives a simple monthly estimate. A lender decides which income can officially be used.
For homebuying, use the estimated NEW monthly housing payment - not your current rent if that rent will end. Include principal + interest + property taxes + homeowners insurance + HOA when applicable.
Use the monthly payment due, not the total balance owed. Example: if a credit card balance is $3,000 but the minimum due is $90, enter $90.
If you do not know your future mortgage payment yet, that is normal. A loan officer can estimate it using the home price, down payment, interest rate, taxes, insurance and HOA.
Lower DTI generally gives you more room in your budget and can make mortgage qualification easier. There is no single DTI cutoff for every loan. The lender, loan program, credit profile and other factors all matter.
Your future housing payment can change based on the home price, interest rate, property taxes, homeowners insurance and HOA. Even if your other debts stay the same, a higher housing payment can raise your DTI.
This worksheet is an estimate. A lender will calculate the official number under the rules for your loan program.
DTI matters, but buying a home is not based on one percentage alone.
A lender may also review:
Do not assume you cannot buy a home. This calculator is only an estimate, and different loan programs can calculate DTI differently. A loan officer can tell you what matters most in your situation.
