What is a good debt-to-income ratio?

A DTI below 36% is considered excellent. Most lenders approve borrowers up to 43% DTI. Above 50% makes approval very difficult for most loan types.

How do I calculate my debt-to-income ratio?

DTI = Total monthly debt payments ÷ Gross monthly income × 100. For example: $1,500 in monthly debts on a $5,000 gross income = 30% DTI.

Does DTI affect mortgage approval?

Yes, significantly. Most conventional mortgages require DTI below 43–45%. FHA loans may allow up to 50% DTI. The lower your DTI, the better the rate you'll qualify for.

How can I lower my debt-to-income ratio?

Two ways: increase income or decrease debt. Pay down credit cards and small loans first, avoid new debt before applying, and consider increasing income through side work. Don't close old accounts as that can hurt credit.

What is Debt-to-Income Ratio (DTI)? How to Calculate & Improve It

📅 May 7, 2025⏱ 7 min read🏦 Loan Qualification

Before a lender approves your loan application, they look at one number above all others: your debt-to-income ratio. It doesn't matter how high your credit score is or how stable your employment — if your DTI is too high, you won't get approved.

This article explains exactly what DTI is, how to calculate yours, what different lenders require, and the most effective ways to lower it.

What is Debt-to-Income Ratio?

Debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward paying debts. Lenders use it to measure your ability to manage monthly payments and repay new debt.

DTI = Total monthly debt payments ÷ Gross monthly income × 100 Example: Monthly debts: $1,400 (rent/mortgage + car + credit cards) Gross income: $5,000/month DTI: $1,400 ÷ $5,000 × 100 = 28%

What Counts as Debt in DTI?

Lenders include all recurring monthly debt obligations. This typically includes:

Mortgage or rent payment
Car loan payments
Student loan payments
Minimum credit card payments (not the full balance)
Personal loan payments
Child support or alimony
Any other installment loans

What's not included: utilities, groceries, health insurance, phone bills, or other living expenses.

💡 Key point: DTI uses your gross income — before taxes — not your take-home pay. And it uses the minimum payment on credit cards, not your actual payment.

DTI Requirements by Loan Type

Loan type	Maximum DTI	Notes
Conventional mortgage	43–45%	Some lenders allow up to 50% with strong compensating factors
FHA mortgage	50%	More flexible for first-time buyers with lower credit
VA loan	41%	For military veterans, no PMI required
Personal loan	40–50%	Varies by lender; higher risk = higher rate
Auto loan	50%	Generally more lenient than mortgage lenders
Credit card	No hard limit	Income, credit score and existing balances more important

Front-End vs Back-End DTI

Mortgage lenders often distinguish between two DTI types:

Front-end DTI (housing ratio): Only your housing costs ÷ income. Most lenders want this below 28%.
Back-end DTI (total debt ratio): All monthly debt payments ÷ income. This is what most people mean by "DTI."

Example: Is this mortgage affordable?

Income: $7,000/month gross. New mortgage payment: $1,800. Car loan: $350. Student loan: $200. Credit cards: $150 minimum.

Front-end DTI: $1,800 ÷ $7,000 = 25.7% ✅ (under 28%)

Back-end DTI: ($1,800 + $350 + $200 + $150) ÷ $7,000 = $2,500 ÷ $7,000 = 35.7% ✅ (under 43%)

This borrower would likely qualify for a conventional mortgage.

How to Lower Your Debt-to-Income Ratio

There are only two levers: reduce your monthly debt payments or increase your income. Here's the most effective approach for each:

Reduce debt payments

Pay off small balances first — eliminating a $200/month car payment has immediate DTI impact
Pay down credit card balances — lower balances = lower minimum payments
Don't open new accounts before applying for a major loan
Refinance high-payment loans to lower the monthly obligation
Consolidate multiple debts into one loan with a lower total payment

Increase gross income

Ask for a raise or take on overtime
Add a part-time job or freelance work
Add a co-borrower with income (increases the denominator in the DTI calculation)

⚠️ Don't do this: Don't close old credit card accounts to "look better." Closing accounts can hurt your credit score by reducing available credit and shortening your credit history. Lenders look at both DTI and credit score.

Real-World Example: Improving DTI Before a Mortgage Application

Before: 47% DTI — likely rejected

Income: $6,000/month. Debts: Car $500 + Student loans $400 + Credit cards $220 + Proposed mortgage $1,700 = $2,820 total. DTI: 47%.

After paying off car loan: 38.7% DTI — likely approved

Same income. Paid off car ($500/month gone). Debts: Student loans $400 + Credit cards $220 + Mortgage $1,700 = $2,320. DTI: 38.7%.

Paying off one car loan before applying — even if it means delaying the mortgage by 6 months — moved this borrower from likely rejected to likely approved.

Key Takeaways

DTI = total monthly debts ÷ gross monthly income × 100
Under 36% is excellent; 36–43% is acceptable for most loans
Mortgage lenders use front-end (housing only) and back-end (all debts) DTI
The most effective way to lower DTI is paying off small balance loans entirely
Never open new credit before a major loan application
