Your debt-to-income ratio is one of the most important numbers in mortgage qualification — and most people have no idea what theirs is. DTI is the percentage of your gross monthly income that goes toward monthly debt payments. Lenders use it to determine how much mortgage you can qualify for.
Use our free interactive DTI Calculator below to see your ratio instantly, find out which loan programs you qualify for, and get specific tips to improve your DTI before you apply. No download required — results update instantly.

Here is how lenders view your DTI — and what it means for your mortgage options:
| DTI Range | Rating | What It Means for Your Mortgage |
|---|---|---|
| Below 36% | ✓ Excellent | Strong qualifying position — access to the best rates and all loan programs |
| 36–43% | ✓ Good | Qualifies for conventional, FHA, and VA — standard underwriting |
| 43–50% | ⚠ Moderate | May qualify with compensating factors — strong credit, reserves, or down payment |
| 50%+ | ✕ High | Difficult to qualify — focus on paying down debt before applying |
Front-End vs. Back-End DTI — What Lenders Actually Look At
Front-end DTI is just your housing payment (mortgage, taxes, insurance, HOA) divided by your gross monthly income. Most programs want this below 28–31%.
Back-end DTI is all your monthly debt payments — including the new mortgage — divided by gross monthly income. This is the number lenders focus on most. Most programs want this below 43–50% depending on loan type and compensating factors.
The calculator above calculates your back-end DTI — the number that matters most for mortgage qualification.
How to Improve Your DTI Before Applying
Pay Off a High-Minimum Debt
Paying off a credit card or small loan completely removes that minimum payment from your DTI calculation. Even eliminating a $100/month payment can meaningfully change your qualifying power — potentially adding $15,000–$20,000 to your purchase price.
Don't Take On New Debt Before Applying
A new car loan, a new credit card, or any new monthly obligation added before your mortgage application raises your DTI immediately. Hold off on any major purchases until after closing day.
Increase Your Income
A side income, raise, or adding a co-borrower increases your gross monthly income — which directly lowers your DTI ratio. Lenders count documented income consistently — part-time, freelance, and rental income all count if properly documented.
Look at a Lower Purchase Price
A lower mortgage payment reduces your back-end DTI. If your DTI is borderline at one price point, running the numbers at a lower price — or a different loan term — might open up your qualifying options significantly.
Frequently Asked Questions
What debts count toward my DTI for a mortgage?
Lenders count monthly minimum payments on installment debt (car loans, student loans, personal loans) and revolving debt (credit card minimums). They also count child support and alimony. They do NOT count utilities, groceries, insurance premiums, subscriptions, or most living expenses. The new mortgage payment is included in the back-end DTI calculation.
What is the maximum DTI for a mortgage?
It depends on the loan type. Conventional loans typically allow up to 45–50% with strong compensating factors. FHA loans can go up to 50–57% in some cases. VA loans generally want DTI below 41% but allow higher with compensating factors. USDA loans typically cap at 41%. These are guidelines — individual lenders and loan scenarios vary. We work with multiple wholesale lenders and can often find options at higher DTI ratios than a single bank might allow.
Does student loan debt affect my DTI?
Yes — student loan payments count toward your back-end DTI. If your loans are in deferment or income-based repayment, lenders typically use either the actual payment or a calculated percentage of the balance — which can vary by loan type. We can walk you through how your specific student loan situation affects your DTI calculation during the pre-approval process.
Can I get a mortgage with a high DTI?
Sometimes yes — with strong compensating factors. A large down payment, high credit score, significant cash reserves, or stable long-term employment can allow lenders to approve higher DTI ratios than standard guidelines. As an independent broker we work with multiple wholesale lenders — some are more flexible on DTI than others for the right borrower profile. Call us and we will tell you honestly what your options look like.
Should I pay down debt or save for a down payment?
It depends on your specific numbers. If your DTI is borderline, paying down debt may do more for your qualifying power than adding to your down payment. If your DTI is already comfortable, building your down payment may be the better move. Use our Purchase Power Calculator and Debt Reduction Calculator together to model both scenarios — then talk to us about your specific situation.
