Debt-to-Income Ratio Calculator
Estimate a basic debt-to-income ratio by comparing recurring monthly debt payments with gross monthly income.

Calculate DTI
Formula
Debt-to-income ratio equals total recurring monthly debt payments divided by gross monthly income.
How to read the result
The ratio shows how much of gross monthly income is already assigned to the listed debt payments. A lower ratio can leave more room for taxes, food, transportation, savings, insurance, and irregular expenses. A higher ratio can signal that a budget may be more sensitive to income changes or unexpected costs.
Because this calculator uses gross income, it does not show take-home pay. Compare the remaining income figure with actual net income before drawing conclusions.
What may be counted differently
Different lenders and programs may include or exclude items such as escrow, alimony, student loans in deferment, lease payments, or minimum credit-card payments. Use this page as an educational estimate, then review the rules for any specific application separately.
Worked example
With $6,000 of gross monthly income and $2,100 in listed monthly debt payments, DTI is 35.0%. That does not mean $3,900 is freely spendable, because taxes, insurance, groceries, savings, and irregular costs still need to be covered.

Document-check checklist
Result quality checklist
- Use gross monthly income that matches the underwriting context you care about.
- Include required monthly debt obligations rather than optional living expenses.
- Check whether the relevant lender counts escrow, leases, or deferred student loans differently.
- Compare DTI with actual take-home pay before assuming remaining income is comfortable.
- Recalculate after any payment change, refinance, or debt payoff.
FAQ
Does DTI include groceries or utilities?
Usually no. DTI normally focuses on recurring debt obligations rather than all living expenses.
Is this a loan approval calculator?
No. It is an educational ratio calculator only and does not replace lender underwriting.
Can lenders count debts differently?
Yes. Different programs can treat escrow, student loans, leases, co-signed debt, and deferred obligations differently.
How to read this debt-capacity snapshot
Read listed debt, DTI ratio, and income remaining together. This page is most useful when it shows whether fixed obligations already consume too much gross income before a new payment is added. It is not loan approval result and does not replace lender underwriting.
Before acting, compare result with pay stubs, credit-card statements, student-loan records, auto-loan bills, housing payment records, and program-specific underwriting rules. See How We Calculate and the Disclaimer for more context.
Method and verification trail
- Method used: Total listed recurring monthly debt is divided by gross monthly income to estimate a simplified back-end DTI ratio.
- Primary source type to verify: Pay stubs, W-2 or income records, mortgage or rent statements, auto-loan bills, student-loan statements, and credit-card minimum-payment records.
- What to confirm in real documents: Whether lender uses gross or verified qualifying income, whether escrow or HOA is included, how deferred student loans are counted, and whether co-signed or lease obligations are treated as debt.
- Scope limit: This page does not fully model front-end DTI, underwriting overlays, residual-income tests, or lender-specific treatment of disputed, deferred, or business debt.
