What Is a Debt-to-Income (DTI) Ratio?

The Debt-to-Income ratio (DTI) is the percentage of your monthly income that goes toward paying debts. It’s a crucial measure lenders use to determine your ability to handle additional credit.

For example:

  • If your monthly income is $4,000 and your monthly debt payments total $1,200, your DTI ratio is 30%.
  • This means 30% of your income is being used to pay debts, leaving 70% for other expenses and savings.

The lower your DTI ratio, the healthier your financial standing.

Why Is DTI Important?

  1. Loan Approval Chances – Lenders use DTI to decide whether you qualify for mortgages, car loans, or personal loans.
  2. Interest Rates – A lower DTI ratio often leads to better loan terms and lower interest rates.
  3. Financial Planning – Understanding your ratio helps you budget better and avoid financial stress.
  4. Debt Management – Identifying a high DTI ratio alerts you to take action before debt becomes unmanageable.

How Our Debt-to-Income Calculator Works

Our calculator is designed to be fast, accurate, and user-friendly. It only requires two inputs:

  • Monthly Income: Enter your total gross income (before taxes).
  • Monthly Debt Payments: Include all recurring debt payments such as credit cards, student loans, mortgages, and auto loans.

Once you enter the values and click Calculate, the tool instantly displays:

  • Debt-to-Income Ratio (%)
  • Status (Good, Fair, or High Risk)

Status Breakdown:

  • Good (0–36%) – Strong financial health. You’re in a safe zone.
  • Fair (37–50%) – Manageable, but lenders may hesitate. Try reducing debt.
  • High Risk (Above 50%) – Critical level. High chance of loan rejections. Consider debt management strategies.

Step-by-Step: How to Use the Debt-to-Income Calculator

  1. Locate the Calculator on our website.
  2. Enter Monthly Income (for example, $5,000).
  3. Enter Monthly Debt Payments (for example, $2,000).
  4. Click Calculate.
  5. Instantly, your DTI ratio and status will appear.
  6. Use the Reset button to clear entries and start again.

Example Calculation

Imagine John earns $6,000 monthly and spends $1,800 on debts (mortgage, student loan, and credit card payments).

  • Debt ÷ Income × 100 = DTI Ratio
  • $1,800 ÷ $6,000 × 100 = 30%

Result: John’s DTI ratio is 30% (Good). This indicates healthy financial management and higher chances of loan approval.

Now, if John’s debt increased to $3,500, the DTI ratio would rise to 58.3% (High Risk). That’s a warning sign for lenders and for John’s financial security.

2. Can I get a mortgage with a high DTI ratio?
It’s possible, but lenders may require a co-signer, higher down payment, or reject the application.

3. Should I include taxes when calculating DTI?
No. Use gross income (before taxes and deductions).

Ideally, every few months or before making major financial decisions.

It indicates high financial risk. Focus on reducing debt immediately.

9. Is DTI the same as credit score?
No. Credit score measures creditworthiness, while DTI measures affordability.

Yes, if you have no debt obligations, your DTI ratio is 0%.
