What Is A Good Debt-To-Income Ratio For A Mortgage?

A total DTI of 36% or less usually gives you the most options. Many buyers still do fine between 36% and 43%. Ratios above 43% can work on some loan programs when the rest of your application is strong. No single number promises an approval.

What Is The Difference Between Housing-Only DTI And Total DTI?

Housing-only DTI uses just your new house payment divided by your monthly income before taxes. Total DTI adds your other required monthly debt payments, like a car loan or credit card minimum, and divides that larger number by the same income.

What Bills Count In A Debt-To-Income Ratio?

Lenders count your new house payment plus required monthly payments such as car loans, student loans, personal loans, minimum credit card payments, and child support or alimony. Everyday costs like groceries, utilities, phone bills, and streaming services are not counted.

Does DTI Use Income Before Or After Taxes?

DTI uses your income before taxes, which lenders call gross monthly income. That includes pay a lender can document, such as salary, steady overtime or bonus pay, and self-employment income shown on your tax returns.

Can I Get A Mortgage With A Higher DTI?

Sometimes, yes. Some programs allow ratios above 43% when other parts of your file are strong, such as extra savings, a higher credit score, or a larger down payment. A higher DTI usually means fewer choices and a closer review, not an automatic no.

How Can I Lower My Debt-To-Income Ratio?

Pay off or pay down a monthly debt, avoid taking on new payments before you apply, increase income a lender can document, put more money down, or look at a lower price so the house payment is smaller.

Do Property Taxes And Home Insurance Count In DTI?

Yes. Lenders use the full house payment, so monthly property taxes, monthly home insurance, HOA dues, and any monthly mortgage insurance or program fee are part of the number.

How To Calculate Debt-To-Income Ratio: A Step-By-Step Guide

Your debt-to-income ratio, or DTI, compares your monthly debt payments to your income before taxes. Lenders use it to help decide how much monthly payment may fit your budget. You do not need to do the math yourself. This guide shows what counts, how lenders look at DTI, and what different DTI ranges can mean.

The DTI Formula

One Simple Formula.

DTI = Monthly Debt Payments ÷ Gross Monthly Income × 100

Housing-Only DTI: your new house payment divided by your income before taxes.
Total DTI: your new house payment plus your other required monthly debts, divided by your income before taxes.

Your house payment can include more than the loan itself. It may include principal and interest, property taxes, home insurance, HOA dues, and monthly mortgage insurance or a program fee when those apply.

How DTI Works

Three Simple Steps.

Start With Your Monthly Income Before Taxes. This is your gross monthly income, which is what you earn each month before taxes come out.
Add Your Monthly House Payment And Other Debts. Other debts are required monthly payments, like a car payment, a student loan, the minimum on a credit card, and child support or alimony if you pay it.
Compare Your Debt To Your Income. The calculator handles the division and turns it into a percentage for you.

A Simple Example

The Same Example Used In The Calculator.

Gross Monthly Income: $7,500
Other Monthly Debt Payments: $600
Purchase Price: $400,000
Down Payment: $40,000
Interest Rate: 6.75%
Loan Term: 30 Years
Property Tax: $5,000 Per Year
Home Insurance: $1,800 Per Year
HOA: $0
Monthly Mortgage Insurance / Program Fee: $0

The Results

Estimated House Payment: $2,902

$2,902 House Payment ÷ $7,500 Gross Monthly Income = 38.7% Housing-Only DTI

$2,902 House Payment + $600 Other Monthly Debts = $3,502 Total Monthly Debt

$3,502 Total Monthly Debt ÷ $7,500 Gross Monthly Income = 46.7% Total DTI

A total DTI of 46.7% means about 47 cents of every pre-tax dollar would go toward the house payment and other required debts. That is higher than many buyers aim for, so this buyer may have fewer loan choices unless they lower a debt, put more money down, or look at a lower price.

What DTI Do Lenders Accept?

There Is No One Number For Every Loan.

36% Or Less
Usually gives you the most flexibility.
Over 36% Through 43%
A common workable range for many buyers.
Over 43% Through 50%
Still possible on some programs when the rest of the file is strong, such as extra savings, a higher credit score, etc.
Above 50%
More limited and usually needs a closer review. Some loan programs may still allow it depending on the full file.

By Loan Type

Conventional: Fannie Mae currently allows a total DTI up to 50% when the loan is approved through its automated system, Desktop Underwriter. When a person reviews the loan by hand instead, the limit is generally 36%, or up to 45% if extra credit score and savings requirements are met.
FHA: FHA does not use one fixed maximum for everyone. FHA loans run through an automated review system, and higher ratios can be approved based on that result and your full application.
VA And USDA: these programs use their own rules and look at more than DTI alone, including income left over each month and your overall credit profile.

A lower DTI usually gives you more options. A higher DTI does not automatically mean no. Credit, savings, down payment, loan type, and the full application also matter.
