Debt-to-Income Calculator
Educational estimate · Not financial advice
Estimate your debt-to-income ratio using monthly debt payments and gross monthly income. Use this tool to compare scenarios, understand assumptions, and decide what questions to ask before choosing an account, loan, or financial strategy.
How to use this calculator
Enter realistic numbers and compare more than one scenario. Small changes in rates, fees, time, income, or payment amounts can meaningfully change the result.
Formula and assumptions
DTI equals monthly debt payments divided by gross monthly income.
Example
If monthly debts are $1,200 and gross income is $6,000, estimated DTI is 20%.
Common mistakes
- Using optimistic rates or returns without testing conservative scenarios.
- Ignoring fees, taxes, insurance, or timing differences.
- Treating an estimate as a guaranteed outcome.

Inputs to double-check
- Use current rates, balances, income, and monthly costs.

- Include fees, taxes, insurance, or closing costs when they affect the decision.
How to interpret the result

How to interpret your debt-to-income result
Debt-to-income ratio compares recurring monthly debt payments with gross monthly income. It helps show how much income is already committed before another payment.
Worked example
Example: $1,800 of monthly debt divided by $6,000 of gross monthly income equals an estimated 30% DTI.
Important limitations
- Lenders may count obligations differently.
- DTI does not include credit score, assets, reserves, or payment history.
- A lower ratio does not guarantee approval.
Before relying on the result
Recheck your inputs, compare more than one scenario, and verify current lender, issuer, provider, tax, or program terms that apply.
