Salary to Debt Ratio

Include all monthly payments on installment debts and revolving credit. This means your mortgage or rent, car loans, student loans, personal loans, minimum credit card payments, and child support or alimony.

Step 1: List every monthly debt payment. Pull your credit report from annualcreditreport.com to catch obligations you might forget.

Step 3: Calculate gross monthly income. Take your annual salary and divide by 12, or if paid hourly, multiply your hourly rate by typical hours per week, then by 4.33.

Step 4: Divide total debt by gross income and multiply by 100. If you earn $7,000 monthly and owe $2,750, the calculation is (2,750 ÷ 7,000) × 100 = 39.3% DTI.

Mortgage lenders typically cap DTI at 43% for qualified mortgages, though FHA loans may allow up to 50% with compensating factors like high credit scores or substantial savings. Conventional conforming loans (Fannie Mae, Freddie Mac) generally prefer 36% front-end (housing only) and 43% back-end (all debts).

These are guidelines, not absolute cutoffs. A 620 credit score with 45% DTI gets rejected where a 760 score with the same DTI might be approved.

Reducing DTI requires either lowering monthly debt payments or increasing income. The fastest route is paying off small debts entirely—eliminating a $150 monthly payment immediately drops your numerator.

Increasing income counts only if it's documentable and recurring. A side gig bringing $800 monthly helps after you've maintained it for 12-24 months and can show tax returns.

DTI becomes critical when applying for major loans. Mortgage pre-approval uses DTI as a primary qualifier—exceed the threshold and you're automatically rejected or offered worse terms.

DTI also guides debt consolidation decisions. If you're at 48% DTI and struggling with payments, consolidation might lower the monthly obligation enough to reach 42%, but won't fundamentally solve overspending.

What's the difference between front-end and back-end DTI?

Front-end DTI includes only housing costs (mortgage, taxes, insurance, HOA fees) divided by gross income. Back-end DTI adds all other debts.

Does rent count in your debt-to-income ratio?

Yes, monthly rent counts as a housing expense in DTI calculations. Lenders include it when evaluating your ability to take on additional debt, though rent doesn't appear on credit reports unless you're applying for a mortgage to replace that rent payment.

Can you get a mortgage with 50% DTI?

Should you include your spouse's income and debts in DTI?

If applying for joint credit, include both incomes and all debts for both applicants. For individual credit applications, include only your income and your individual debts, but debts you co-signed with your spouse count against you regardless of who makes the payment.
