Debt-to-Income Ratio Calculator — What Is My DTI?
Your debt-to-income ratio (DTI) is one of the most important numbers in mortgage qualifying — and most buyers have no idea what theirs is. Lenders use DTI to determine how much of a mortgage you can qualify for. Too high and you will not qualify. Even slightly elevated and you may qualify for less than you expected.
Our free DTI Calculator shows you your current ratio, what it means for mortgage qualifying, and exactly what you need to do to improve it before you apply.

Excellent ✓
Strong position. You qualify for conventional loans with the best rates. Lenders view this as financially healthy and low risk.
Acceptable ✓
Within conventional loan limits. You qualify for most programs. Higher end of this range may affect your interest rate slightly.
Elevated ⚠
Above conventional limits but may qualify for FHA. Approval depends on compensating factors like credit score and reserves.
Too High ✗
Most loan programs will not approve above 50%. Need to pay down debt or increase income before applying for a mortgage.
Front-End vs. Back-End DTI — What Is the Difference?
There are actually two DTI ratios lenders look at — and it is important to understand both:
Front-End DTI (Housing Ratio)
Your proposed monthly housing payment — principal, interest, taxes, and insurance — divided by your gross monthly income. Conventional loans typically want this under 28%. FHA allows up to 31%. This ratio tells lenders how much of your income goes specifically to housing costs.
Back-End DTI (Total DTI)
All monthly debt payments — housing plus all other debts — divided by gross monthly income. This is the number most people mean when they say DTI. Conventional loans cap this at 43% for most borrowers. FHA allows up to 50% with compensating factors. This is what our calculator computes.
The Single Fastest Way to Improve Your DTI
Pay off your smallest debt entirely before applying. Here is why: every dollar of minimum monthly payment you eliminate directly reduces your DTI. A $250/month car payment that you pay off before applying can increase your mortgage qualification by $40,000 or more at current rates.

Most conventional loans require a back-end DTI of 43% or below. FHA loans allow up to 50% with compensating factors like a high credit score or significant reserves. VA loans prefer 41% but have more flexibility. The lower your DTI, the stronger your application and the better your rate. A DTI below 36% puts you in the strongest possible position.
Does DTI affect my interest rate?
DTI itself does not directly set your rate — credit score and loan-to-value ratio are the primary rate drivers. However, a high DTI can push you toward loan programs with less competitive rates, and lenders may require compensating factors like a larger down payment or higher credit score if your DTI is elevated. Getting your DTI below 36% opens up the full range of conventional loan options at the best available rates.
Does my spouse's debt count toward our DTI if we apply together?
Yes — if you apply jointly, both incomes and both debt obligations are included in the DTI calculation. This can work in your favor (combining incomes increases buying power) or against you (combining debts increases DTI). If one spouse has significantly more debt than income contribution, it may sometimes make sense to apply in only one name — though this reduces the income used for qualification. We will run both scenarios for you and recommend the best approach.
What counts as income for DTI purposes?
Lenders use verifiable, stable gross income — salary, wages, self-employment income (averaged over 2 years), Social Security, pension, rental income (typically 75% of gross rent), and regular documented bonus or commission income. Side hustle income typically needs a 2-year history to count. Overtime income is usually averaged over 2 years. We will tell you exactly which income sources count and how to document them for the strongest application.
