Your Complete Guide to Understanding and Calculating Debt-to-Income Ratio
Imagine you're planning your monthly budget and wondering, "Am I carrying too much debt?" That's where the Debt-to-Income Ratio comes in - it's like a financial report card that tells you how well you're managing your money!
This guide will walk you through everything you need to know about this crucial financial metric, complete with real examples, simple formulas, and our interactive calculator that does all the math for you.
What Is Debt-to-Income Ratio?
Debt-to-Income Ratio (DTI) is a simple percentage that compares your monthly debt payments to your monthly income. Think of it as measuring how much of your paycheck goes toward paying off debts each month.
Simple Example:
If you earn $5,000 per month and your total debt payments are $1,500:
- You're spending $1,500 on debt each month
- Your Debt-to-Income Ratio would be 30%
- This means 30% of your income goes to debt payments

The Simple Formula Behind the Calculator
The Magic Formula:
Expressed as a percentage
Let's break this down into simple terms:
What Counts as Monthly Income?
Total Monthly Income includes all the money you receive regularly each month. Typically, this includes:
Income Sources:
- Gross salary (before taxes)
- Part-time job income
- Freelance or side gig income
- Investment income (if regular)
- Rental income
- Child support or alimony (if received)
Important: Use your gross income (before taxes) for consistency with how lenders calculate it.
What Counts as Monthly Debt?
Total Monthly Debt includes all regular debt payments you make each month. Common debts include:
Debt Payments Include:
- Mortgage or rent payments
- Car loan payments
- Student loan payments
- Credit card minimum payments
- Personal loan payments
- Any other regular loan payments
Note: Only include the minimum required payments - not the total balance you owe.
Visualizing Your Debt Ratio
Monthly Income: $5,000
40% for debt payments ($2,000)
60% for other expenses ($3,000)
The pie chart above shows what a 40% debt ratio looks like. The colored section represents debt payments, while the remaining portion is available for other expenses and savings.
Putting It All Together
Complete Calculation Example:
Let's say Sarah has:
Monthly Income:
- Salary: $4,500
- Freelance work: $500
- Total Income: $5,000
Monthly Debt Payments:
- Mortgage: $1,200
- Car loan: $300
- Student loans: $200
- Credit cards: $100
- Total Debt: $1,800
Sarah's debt-to-income ratio is 36%, which means 36% of her monthly income goes toward debt payments.
What Does Your Ratio Mean?
Different ratios tell different stories about your financial health. Here's how lenders and financial experts interpret them:
| Ratio Range | What It Means | Financial Health | Action Needed |
|---|---|---|---|
| Below 36% | Low debt burden - You're managing debt well | ✅ Excellent | Maintain current strategy |
| 36% - 43% | Moderate debt - Manageable but watch carefully | ⚠️ Moderate | Monitor and avoid new debt |
| 44% - 49% | High debt - May struggle with payments | ⚠️ High Risk | Consider debt reduction strategies |
| 50%+ | Very high debt - Financial stress likely | 🚨 Critical | Immediate debt reduction needed |
Pro Tip: The 28/36 Rule
Many lenders use this guideline: Your housing expenses (mortgage/rent) should not exceed 28% of your gross income, and your total debt payments should not exceed 36% of your gross income.
