What Is Debt-to-Income Ratio?
Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward paying debts. It is the single most important number lenders look at when deciding whether to give you a loan -- and it is the number you should be watching if you are worried about your financial health.
There are two types of DTI:
- Front-end DTI -- only your housing costs (mortgage/rent, property taxes, insurance, HOA) divided by gross income
- Back-end DTI -- all monthly debt payments (housing + car loans + student loans + credit card minimums + personal loans + child support/alimony) divided by gross income
When people say "DTI ratio" without specifying, they usually mean back-end DTI. That is the number that matters most.
How to Calculate Your DTI
The formula is simple:
DTI = (Total Monthly Debt Payments / Gross Monthly Income) x 100
What Counts as "Monthly Debt Payments"
- Mortgage or rent payment
- Property taxes and homeowner's insurance (if not included in mortgage)
- Car loan or lease payments
- Student loan payments (use actual payment, not deferred amount)
- Credit card minimum payments
- Personal loans
- Child support or alimony
- Any other recurring debt obligation
What Does NOT Count
- Utilities (electric, gas, water, internet, phone)
- Groceries and food
- Health insurance premiums
- Transportation costs (gas, maintenance)
- Subscriptions and entertainment
- Income taxes (already excluded since you use gross income)
Example
Say your gross monthly income is $5,000. Your monthly debts are:
- Rent: $1,200
- Car payment: $400
- Student loans: $300
- Credit card minimums: $150
Total monthly debt: $2,050. DTI = $2,050 / $5,000 = 41%
That puts you in the "stressed" zone. Most conventional mortgage lenders would not approve you for additional credit. Use our calculator to check your own DTI.
DTI Thresholds -- What the Numbers Mean
| DTI Range | Rating | What It Means |
|---|---|---|
| Under 36% | Healthy | Most lenders consider you a good risk. You qualify for the best rates. |
| 36% -- 43% | Manageable | You can still qualify for most loans (FHA accepts up to 43%), but you are stretched. One income disruption could push you into crisis. |
| 43% -- 50% | Stressed | Most new credit applications will be denied. You are one emergency away from missing payments. Consider aggressive debt reduction. |
| Over 50% | Critical | More than half your income goes to debt. This is often unsustainable. Bankruptcy or formal debt relief may be warranted. |
Why DTI Matters
For Mortgages
DTI is the primary gatekeeper for mortgage approval. FHA caps at 43% (sometimes 50% with compensating factors). Conventional loans want under 36% front-end and under 45% back-end. Full mortgage DTI breakdown.
For Credit Cards and Personal Loans
While credit card companies do not publish DTI cutoffs, they absolutely check your income and existing debt. High DTI means higher APRs, lower credit limits, or outright denial.
For Bankruptcy
DTI is not the bankruptcy means test -- that is a separate calculation based on median income by state and household size. But high DTI is often the first sign that the means test will be passed. If your DTI is over 50%, you should seriously evaluate whether the means test would qualify you for Chapter 7.
For Financial Health Generally
DTI is a stress indicator. Research consistently shows that households with DTI over 40% are significantly more likely to miss payments, default on loans, and face collection actions. It is one of the most reliable predictors of financial distress.
Front-End vs. Back-End DTI
Mortgage lenders care about both numbers:
Front-end DTI = Housing costs only / Gross income
The conventional guideline is 28% or less. FHA allows up to 31%.
Back-end DTI = All debt payments / Gross income
The conventional guideline is 36% or less. FHA allows up to 43%.
If your front-end DTI is fine but your back-end DTI is high, that means non-housing debt (credit cards, car loans, student loans) is the problem. That is actually the easier scenario to fix -- those debts are often dischargeable in bankruptcy.
