Debt-to-Income (DTI) Ratio Calculator 2025

Introduction

Your Debt-to-Income (DTI) Ratio is one of the most important factors lenders use to approve mortgages and loans. A DTI Calculator shows where you stand and what you need to improve.


How to Calculate DTI

Formula

DTI = (Total Monthly Debt Payments / Gross Monthly Income) × 100

Example:

  • Gross Income: $6,000/month
  • Debts: $1,200 car loan + $300 student loan + $500 credit cards = $2,000
  • DTI: ($2,000 / $6,000) × 100 = 33%

What's a Good DTI?

DTI RangeStatus
\u003c 20%Excellent
20-35%Good
36-42%Acceptable (harder to qualify)
43%+High risk (many lenders won't approve)

Note: For most mortgages, lenders prefer DTI below 43%.


Front-End vs. Back-End Ratios

Front-End Ratio

Housing expenses only (mortgage, taxes, insurance).

  • Target: ≤ 28%

Back-End Ratio

All debt payments (housing + car + student loans + credit cards).

  • Target: ≤ 36%

How to Improve Your DTI

  1. Pay off small debts to reduce monthly obligations.
  2. Increase income through side hustles or raises.
  3. Avoid new debt before applying for a mortgage.
  4. Refinance existing loans to lower payments.

FAQ

Q: Does rent count toward DTI? A: Only if you're applying for a mortgage. Lenders replace rent with the new mortgage payment in their calculation.

Q: Do utilities count? A: No. Only debts reported to credit bureaus (loans, credit cards) count.
