What Is a Debt-to-Income Ratio Calculator?
A Debt-to-Income (DTI) Ratio Calculator helps you determine what percentage of your gross monthly income goes toward paying your monthly debt obligations. Lenders use your DTI ratio to evaluate your ability to manage monthly payments and repay new debt.
Your debt-to-income ratio is one of the most important factors considered when applying for a mortgage, auto loan, personal loan, or other types of financing. A lower DTI ratio generally indicates stronger financial health and may improve your chances of qualifying for a loan with favorable terms.
Whether you're preparing to buy a home, refinance an existing loan, or simply improve your finances, our DTI Ratio Calculator provides a quick and accurate estimate of your debt-to-income ratio.

What Counts as Monthly Debt?
Lenders generally include recurring debt obligations such as:
- Mortgage or rent payments
- Auto loans
- Student loans
- Credit card minimum payments
- Personal loans
- Home equity loans or HELOC payments
- Child support or alimony (when applicable)
Expenses such as groceries, utilities, entertainment, insurance premiums, and retirement contributions are generally not included in your DTI calculation.
What Is a Good Debt-to-Income Ratio?
While every lender has different qualification requirements, these general guidelines are commonly used:
35% or Lower
A DTI ratio below 35% is generally considered healthy and indicates that your debt is manageable.
36% to 43%
Many lenders consider this range acceptable for mortgage and other loan approvals, although additional factors such as your credit score and savings may also be evaluated.
44% to 50%
Borrowers in this range may still qualify for certain loans but could face stricter lending requirements or higher interest rates.
Above 50%
A DTI ratio above 50% may make it more difficult to qualify for new financing. Reducing debt before applying for a loan may improve your approval chances.
Tips for Improving Your Debt-to-Income Ratio
- Pay down credit card balances.
- Make extra payments toward loans whenever possible.
- Avoid taking on new debt before applying for financing.
- Increase your income through raises, bonuses, or additional employment if possible.
- Refinance high-interest loans to reduce monthly payments.
- Delay large purchases until your debt ratio improves.

What is considered a good DTI ratio?
