What Is a Good Debt-to-Income Ratio?
Your DTI is the first number a mortgage lender checks — often before your credit score. Here's what counts as good, the limits by loan type, and how to lower yours before you apply.
What is a debt-to-income ratio?
Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes to debt payments. If you earn $6,000 a month before tax and pay $2,100 toward debts, your DTI is 35%.
Lenders love this number because it answers the question they care about most: can this person actually afford another payment? A great credit score says you pay on time; a low DTI says you have room to keep doing it.
There are two versions, and mortgage lenders check both:
- Front-end DTI — housing costs only (rent or mortgage, property tax, insurance) divided by gross income.
- Back-end DTI — all monthly debt payments divided by gross income. This is the headline number, and the one people mean when they just say "DTI."
How to calculate it (with example)
Add up your monthly debt payments, divide by gross monthly income, multiply by 100:
DTI = (total monthly debt payments ÷ gross monthly income) × 100
Say you earn $75,000 a year — $6,250 a month before tax — and each month you pay:
- Rent: $1,600
- Car loan: $420
- Student loans: $280
- Credit card minimums: $100
That's $2,400 in debt payments, so your DTI is $2,400 ÷ $6,250 = 38%. Your front-end (housing-only) ratio is $1,600 ÷ $6,250 = 26%.
Don't want to do the math by hand? The free debt-to-income calculator does both ratios instantly and tells you how lenders would rate the result.
What lenders consider good
- Under 28%: excellent. Plenty of borrowing room; you'll sail through affordability checks.
- 28–36%: healthy. This is the range most lenders want to see — the classic guideline is housing under 28% and total debt under 36% (the "28/36 rule").
- 37–43%: manageable, but tight. Many lenders will still approve a mortgage here, but you may get worse rates and less flexibility, and payments are crowding out saving.
- Over 43%: high. This is the traditional cap for a "qualified mortgage" — above it, most mainstream lenders decline, and the loans you can get cost more.
Note the gap between "approvable" and "comfortable." A lender may happily approve you at 43% — that doesn't mean the payment will feel fine alongside groceries, childcare, and saving for retirement. If you're deciding what you can comfortably borrow, run the home affordability calculator, which works backwards from these same ratios.
DTI limits by loan type
Exact ceilings vary by lender and by the rest of your file (credit score, down payment, cash reserves), but these are the typical back-end limits:
- Conventional mortgage: up to 43–45%, occasionally 50% with strong compensating factors.
- FHA loan: more forgiving — commonly up to 43%, and up to ~50% with strong credit or reserves.
- VA loan: guideline of 41%, but flexible if residual income is strong.
- Auto loans and personal loans: many lenders cap total DTI around 40–50%, with the best rates going to borrowers well below that.
The pattern: the lower your DTI, the more options you have and the less you pay. Getting from 44% to 41% can be the difference between a decline and an approval; getting from 38% to 34% can mean a meaningfully better rate.
What counts as debt — and what doesn't
DTI counts obligations on your credit report, not everyday spending.
- Counts: rent or mortgage payment, car loans and leases, student loans, credit card minimum payments, personal loans, child support or alimony, and buy-now-pay-later plans that report.
- Doesn't count: utilities, groceries, phone plans, streaming subscriptions, insurance premiums (except those escrowed in a mortgage payment), gym memberships, and taxes.
Two details that surprise people: lenders use your credit card minimums, not your balances or what you actually pay — and they use gross (pre-tax) income, not take-home pay. If you're not sure what your gross monthly figure is, the paycheck calculator shows the gross-to-net breakdown.
5 ways to lower your DTI
DTI has only two moving parts — debt payments and income — so every fix is a version of shrinking one or growing the other:
- 1. Knock out a whole payment. Eliminating one debt entirely helps more than paying extra on several. A car loan with a $420 payment and a $3,000 balance is the classic target: clearing it drops the example above from 38% to 31%. The debt payoff calculator will show which of your debts dies fastest.
- 2. Pay credit cards down before the statement date. Minimums are usually a percentage of the balance, so lowering the balance lowers the payment that lenders count.
- 3. Consolidate high-rate debt. Rolling several high-interest payments into one lower-rate loan can cut your total monthly obligation — see when consolidation actually helps.
- 4. Don't add new debt before applying. A new car lease or financed furniture in the months before a mortgage application is one of the most common self-inflicted declines.
- 5. Grow the denominator. A raise, documented side income, or adding a co-borrower's income all lower the ratio without touching the debt.
If a mortgage is the goal, start 6–12 months ahead: that's enough time to clear a small loan, let card balances report lower, and let any income increase show up in your documents.
DTI vs credit utilization
These two ratios get mixed up constantly, and the confusion matters because they're improved differently:
- DTI = debt payments ÷ income. It's invisible to your credit score — income isn't on your credit report. Lenders calculate it themselves when you apply.
- Credit utilization = card balances ÷ credit limits. It has nothing to do with income and is a major credit-score factor.
Paying down credit cards is the rare move that improves both at once — which is why it's the standard advice before any big loan application. For the score side of the equation, see how to improve your credit score.

What is a good debt-to-income ratio?
36% or below is what most lenders consider healthy. Between 37% and 43% is manageable but tighter, and above 43% makes qualifying for a mortgage difficult with most lenders.
Is DTI calculated with gross or net income?
Gross (pre-tax) income. Lenders always use your income before taxes and deductions when calculating your debt-to-income ratio.
Do rent and utilities count toward DTI?
Rent or a mortgage payment counts; utilities, groceries, insurance premiums, and subscriptions do not. DTI only counts debt obligations, not everyday living expenses.
Does my DTI affect my credit score?
No — income isn't on your credit report, so DTI never touches your score. Lenders check it separately. The score-related ratio is credit utilization: your card balances versus your credit limits.
