Managing personal finances is not just about how much you earn, but also how much of your income goes toward paying off debts. One of the most important financial metrics used by lenders, financial advisors, and individuals is the Debt-to-Income (DTI) Ratio. This ratio provides a clear picture of your ability to manage debt responsibly compared to your income.
To help you evaluate your financial situation easily, we’ve built an interactive Debt-to-Income Calculator. With just two simple inputs—your total monthly debt payments and your gross monthly income—you can quickly calculate your DTI ratio and understand whether your finances are in a healthy range.

What is Debt-to-Income Ratio (DTI)?
The Debt-to-Income ratio (DTI) is a percentage that compares your monthly debt payments to your gross monthly income (income before taxes). It tells lenders how much of your income is already committed to existing debt obligations.
- A low DTI indicates financial stability and makes it easier to qualify for loans.
- A high DTI may signal higher risk for lenders, meaning you might face challenges in getting approved for mortgages, credit cards, or other types of loans.
Why is DTI Important?
Your DTI ratio matters because it’s one of the first things lenders look at when deciding whether to approve you for credit or a loan.
- Mortgage Approval: Most mortgage lenders prefer a DTI ratio of 36% or lower.
- Credit Score Impact: While DTI does not directly affect your credit score, high debt relative to income can lead to missed payments, which do impact your score.
- Financial Planning: Even if you’re not applying for a loan, knowing your DTI helps you stay in control of your debt.

Example of Debt-to-Income Ratio Calculation
Let’s say:
- Total Monthly Debt Payments = $1,200
- Gross Monthly Income = $4,000
Calculation: DTI=(1,2004,000)×100=30%DTI = \left(\frac{1,200}{4,000}\right) \times 100 = 30\%DTI=(4,0001,200)×100=30%
Result:
A 30% DTI falls under the “Good” range, which means you are managing debt well and still have room for additional financial commitments if needed.
Understanding Your DTI Result
The calculator categorizes results into four ranges:
- Excellent (Below 20%) → Strong financial position, highly attractive to lenders.
- Good (20% – 35%) → Acceptable range, manageable debt.
- Fair (36% – 49%) → Risky territory; lenders may hesitate or offer higher interest rates.
- High Risk (50% and above) → Very high debt load; loan approvals become difficult.
