How to calculate debt payment percentage
This calculator finds what percentage of your gross monthly income goes toward debt payments — a version of the debt-to-income ratio lenders use to assess how much additional debt you can reasonably take on, and a useful check on your own budget health.
How the calculation works
Debt payment percentage = (Monthly debt payments ÷ Monthly gross income) × 100. This produces the percentage of your income already committed to debt obligations like loans, credit cards, and other recurring debt payments — rent and utilities are typically not counted as 'debt' in this specific ratio.
Example
With $1,200/month in combined debt payments (car loan, student loan, credit card minimums) against a $6,000/month gross income: debt payment percentage = ($1,200 ÷ $6,000) × 100 = 20%. Many mortgage lenders consider ratios under 36% (including the new mortgage payment) favorable, though specific thresholds vary by loan type and lender.
Frequently asked questions
What debt payment percentage is considered good?
Guidelines vary by lender and loan type, but many conventional mortgage lenders look favorably on a total debt-to-income ratio (including the new mortgage) at or below roughly 36–43%. Lower is generally better for approval odds and interest rate offers.
Should I include rent in my debt payments?
For this standard debt-to-income style calculation, no — rent is typically treated separately, and if you're evaluating a mortgage application, your rent would be replaced by the new mortgage payment in the numerator instead.

Pro Tips for Debt Payment Percentage
- Include all recurring debt obligations — auto loans, student loans, credit card minimum payments, personal loans — but not typically rent, utilities, or insurance, which are usually excluded from this specific ratio.
- If you're preparing to apply for a mortgage, calculate this both with and without the anticipated new mortgage payment to see your current ratio versus your ratio after taking on the loan.
- A lower percentage generally means more flexibility for saving, unexpected expenses, or additional borrowing — it's a useful self-check even outside of loan applications.
Common Debt Payment Percentage Mistakes to Avoid
- Using net (take-home) income instead of gross income — lenders and most standard versions of this ratio use gross monthly income, so mixing the two will produce a ratio that isn't comparable to typical lending thresholds.
- Leaving out a debt payment because it's small — minimum credit card payments and small personal loans still count and can meaningfully shift the ratio when added together.
