Debt-to-Income Ratio: What It Is and How to Lower Yours
6 min read · Personal Loans
Your debt-to-income ratio (DTI) is one of the most important numbers lenders evaluate when you apply for a loan. It can get you approved or denied regardless of your credit score. Here's exactly what it is, how to calculate it, and how to improve it before you apply.
What Is Debt-to-Income Ratio?
DTI is the percentage of your gross monthly income that goes toward debt payments. Lenders use it to measure whether you have enough income left over after current obligations to handle a new loan payment reliably.
There are two versions lenders may look at:
- Front-end DTI: Housing costs only (mortgage/rent) ÷ gross monthly income. Mortgage lenders focus heavily on this. Target: below 28%.
- Back-end DTI: All monthly debt payments ÷ gross monthly income. This is what personal loan lenders care about most. Target: below 36–43%.
How to Calculate Your DTI
Step 1: Add up all monthly debt payments
Include: mortgage or rent, car payments, minimum credit card payments, student loan payments, personal loan payments, child support or alimony, and any other recurring debt obligations. Do not include utilities, groceries, insurance, or subscriptions — these aren't debt.
Step 2: Determine your gross monthly income
This is your income before taxes. If you're salaried, divide your annual salary by 12. If you're hourly, multiply your average weekly hours by your hourly rate, then multiply by 52 and divide by 12. If self-employed, use your average net income from the last 2 years of tax returns.
Step 3: Divide and convert to a percentage
DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100
DTI Example
| Monthly Debt Payment | Amount |
|---|---|
| Rent | $1,400 |
| Car payment | $380 |
| Student loan | $250 |
| Credit card minimums | $120 |
| Total monthly debt | $2,150 |
If gross monthly income = $6,500:
DTI = $2,150 ÷ $6,500 = 33% ✓ (good range)
What DTI Ranges Mean for Loan Approval
| DTI Range | Lender's View |
|---|---|
| Below 20% | Excellent — easily qualifies, best rates |
| 20%–35% | Good — qualifies for most loans, competitive rates |
| 36%–43% | Acceptable — may qualify with strong credit or income |
| 44%–50% | Risky — many lenders decline; some specialty lenders may approve |
| Above 50% | Very difficult — most lenders will decline |
6 Ways to Lower Your DTI Before Applying
1. Pay Down Credit Card Balances
Credit card minimum payments are included in your DTI calculation. Paying down balances reduces your minimum payment — sometimes to zero on smaller cards. Even eliminating one $50/month minimum can meaningfully reduce your DTI.
2. Pay Off Small Debts Entirely
If you have small debts close to being paid off (a personal loan with 4 payments left, a small credit card balance), paying them off entirely removes that monthly payment from your DTI calculation completely.
3. Increase Your Income
A raise, a side income, or documenting income you weren't previously claiming (freelance work, rental income) all increase your denominator. Even a $300/month increase in income can lower a borderline DTI by 2–4 points.
4. Avoid Taking on New Debt Before Applying
Don't finance a car, open new credit cards, or take on any other debt in the months before applying for a loan. Each new payment raises your DTI.
5. Refinance Existing Loans at Lower Rates
Refinancing a car loan or student loan at a lower rate reduces your minimum monthly payment, lowering your DTI. Even a modest reduction per month adds up in the DTI calculation.
6. Request a Credit Limit Increase (Carefully)
If your credit card minimum payments are a function of your balances, getting a limit increase on existing cards doesn't directly lower DTI — but it can lower your credit utilization ratio, improving your credit score, which may unlock better loan terms even at the same DTI.
DTI vs. Credit Score: Which Matters More?
They serve different purposes in a lender's evaluation. Your credit score tells the lender how reliably you've managed debt in the past. Your DTI tells them whether you have the current financial capacity to take on new debt. Both matter — a great credit score can sometimes compensate for a borderline DTI, but a DTI above 50% will often result in denial regardless of credit score.
Frequently Asked Questions
Is rent included in DTI?
Yes — rent is included in your back-end DTI calculation (the one personal loan lenders use). It's one of the largest components for most borrowers. If you're applying for a mortgage, the new proposed housing payment is used instead of your current rent.
Does income type matter for DTI?
Lenders consider different income types differently. Salaried income is most reliable. Hourly income with consistent hours is also straightforward. Variable income (bonuses, commissions, self-employment, gig work) is typically averaged over 2 years from tax returns. Rental income, investment income, and alimony can usually be counted if documented.
Can I get a loan with a high DTI?
Yes, in some cases. Borrowers with high DTI but exceptional credit scores, large assets, or a co-signer may still qualify. Some lenders — particularly online lenders and loan matching networks — are more flexible with DTI than traditional banks. However, a higher DTI will typically mean a higher interest rate and lower loan amount.
