A lender may compare annual obligations with income when reviewing an application. Enter matching-period figures to see the simple debt ratio, then check which obligations the lender actually counts.
How to use this calculator
- Enter gross annual income, annual debt payments.
- Select Calculate to see the answer and its breakdown.
- Keep a scenario, change an input and compare the results.
Use consistent units and check the assumptions below before applying the result.
How debt ratio is calculated
This combines the two annual amounts and applies one assumed effective rate. It does not model filing status, tax brackets, credits or separate state and local taxes. Formula: Debt-to-income ratio = annual debt payments ÷ gross annual income. Use the displayed details to inspect the intermediate amounts and replace example assumptions with terms from your own quote or records.
Debt-to-income ratio = annual debt payments ÷ gross annual income.Annual debt payments of $24,000 against $80,000 gross income equal 30%.
Assumptions & useful context
The result depends on the values you enter and the method described above. Displayed numbers may be rounded; calculations use the unrounded values. Check that this model matches your situation before relying on it.

No. It applies one assumed effective rate to combined income and is only a broad scenario. Filing status and tax brackets can change the result.
Debt Ratio Calculator: which assumptions matter most?
Use the same effective-rate assumption consistently for a rough comparison, then model credits, deductions and local taxes separately.
