Understanding Your Debt-to-Income Ratio
Your Debt-to-Income (DTI) ratio is a critical financial metric used by lenders to assess your ability to manage monthly payments and repay debts. It compares how much you owe each month to how much you earn.
How is DTI Calculated?
The formula for calculating DTI is straightforward:
DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100
For example, if your gross monthly income is $5,000 and you have the following debts:
- Mortgage: $1,200
- Car Loan: $350
- Student Loan: $250
- Credit Cards: $200
Your total monthly debt is $2,000. Your DTI would be ($2,000 ÷ $5,000) × 100 = 40%.
What is a Good DTI Ratio?
Lenders generally prefer lower ratios, as they indicate less financial stress. Here is a general breakdown:
- 35% or less: Good. You have manageable debt relative to your income.
- 36% to 49%: Manageable, but lenders may require stricter conditions.
- 50% or higher: High Risk. You may struggle to obtain new loans or mortgages.
How to Lower Your DTI
To improve your ratio, you can either increase your income or decrease your debt. Strategies include paying off high-interest credit cards, refinancing loans to lower monthly payments, or adding a side income stream.

// Get Income
var income = parseFloat(document.getElementById('grossIncome').value);

}
// Calculate Total Debt
