What is the Debt-to-Income Ratio Calculator?
Calculate your debt-to-income (DTI) ratio, a key number lenders use for mortgages and loans. Money decisions are easier when you can see the numbers. Our finance calculators use the same standard formulas banks and financial planners use — amortization, compound interest and present-value math — so you can compare options before you commit.
How to use the Debt-to-Income Ratio Calculator
- Enter your monthly debt payments, your gross monthly income.
- Results update automatically as you type; you can also press Calculate.
- Read the output: dti ratio, assessment.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With monthly debt payments = $1,800, gross monthly income = $6,500, the Debt-to-Income Ratio Calculator returns dti ratio: 27.69%; assessment: Good — most lenders prefer 36% or less.
Tips for better results
- Compare at least two scenarios (for example, a 15- vs 30-year term) before deciding.
- Small rate differences compound: a 0.5% lower rate can save thousands over a long loan.
- Results are estimates; your lender’s fees, taxes and exact day-count rules may change the final figure.
