Step-by-step proofCheck by hand
This is a general DTI estimate, not a lending decision. Lenders calculate DTI differently — some exclude certain debts or include projected housing costs — and use it alongside credit score, assets and other factors. Consult a mortgage or financial professional for how a specific lender will evaluate your application.

How DTI is calculated

Debt-to-income ratio is your total recurring monthly debt payments divided by your gross (pre-tax) monthly income, expressed as a percentage. Lenders use it — alongside credit score and other factors — to judge how much more debt you could reasonably take on.

The bands, in full
Under 36%: good. 36–43%: acceptable for most lenders. 43–50%: risky — above the CFPB's qualified-mortgage backstop. 50% and above: concerning — over half of income already goes to debt.
Gross, not take-home
DTI uses gross (pre-tax) income, not your take-home pay — a common mix-up that makes the ratio look worse than a lender would calculate it.

The formula

DTI = total monthly debt payments ÷ gross monthly income

Worked example

$1,800 in monthly debt payments against $6,000 gross monthly income: 1,800 ÷ 6,000 = 30.0% — in the "Good" band.

Frequently asked questions

What counts as a monthly debt payment for DTI?
Recurring debt obligations: rent or mortgage (including property tax and insurance if escrowed), car loans, student loans, minimum credit card payments, and personal loan payments. It does not include everyday living expenses like groceries, utilities, or insurance premiums that aren't tied to a loan.
What's a good DTI ratio?
Most lenders consider 36% or below healthy, and the Consumer Financial Protection Bureau's "qualified mortgage" rule generally caps DTI at 43% for that loan category (though many lenders offer other products above that). Below 36% typically means the widest range of loan options and the best rates.
Is DTI the same as a credit utilization ratio?
No — credit utilization compares your credit card balances to your credit limits and affects your credit score. DTI compares your monthly debt payments to your income and is used by lenders to judge whether you can take on more debt. They're both about debt, but they measure different things.
