Live calculation note

DTI uses gross (pre-tax) income, not take-home pay. Include the minimum monthly payment required for each debt, not the full balance. Most mortgage lenders look for DTI under 43%, with under 36% considered ideal. Empty or negative entries are treated as $0.

How a debt-to-income calculator helps you qualify for loans

Your debt-to-income ratio is the single most important number lenders use to decide whether to approve you for a mortgage, auto loan, or personal loan. The formula is simple: add up every minimum monthly debt payment you have, divide that total by your gross monthly income, and multiply by 100. The result is your DTI as a percentage. Lower is better, and most experts consider anything under 36% healthy.

This calculator separates housing from other debts and lets you enter credit cards, student loans, auto loans, personal loans, and other obligations individually. It then calculates your total monthly debt, your DTI percentage, your remaining monthly income after debt payments, and provides a plain-English interpretation. The visual income-vs-debt breakdown shows at a glance how much of your paycheck is spoken for before you even start budgeting for groceries, utilities, savings, or investing.

If your DTI is too high to qualify for the loan you want, you have two levers to pull: lower your debt or raise your income. To plan a debt payoff strategy, try our Debt Payoff Calculator. To see how a new loan would affect your DTI, use our Loan Payment Estimator. To understand credit factors that work alongside DTI, read about how credit scores are calculated and credit utilization. For homebuyers, our Mortgage Calculator can show how your housing payment changes total DTI.

FAQ

Debt-to-income calculator FAQs

What is a debt-to-income ratio?

Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward paying monthly debts. Lenders use DTI to assess your ability to manage payments and repay new credit. The formula is total monthly debt payments divided by gross monthly income, multiplied by 100.

How do I calculate my DTI?

Add up all your minimum monthly debt payments — credit cards, student loans, auto loans, mortgage or rent, personal loans, and any other obligations. Divide that total by your gross (pre-tax) monthly income, then multiply by 100. For example, $1,800 in monthly debt against $6,000 in gross monthly income equals a 30% DTI.

What is a good debt-to-income ratio?

A DTI below 36% is considered good by most lenders, with 20% or less viewed as excellent. Many mortgage lenders set a maximum of 43% DTI for qualified borrowers, and some FHA loans allow up to 50%. The lower your DTI, the more financial flexibility you have and the better the loan rates you will qualify for.

Does DTI affect my credit score?

DTI itself does not appear on your credit report and does not directly impact your credit score. However, the underlying debt balances and your credit utilization ratio do affect your score. A high DTI can also make it harder to qualify for new credit, even if your credit score is strong.

Should I use gross or net income for DTI?

Always use gross (pre-tax) monthly income. Lenders calculate DTI based on gross income because it is consistent and verifiable through W-2 forms, pay stubs, or tax returns. Using net (after-tax) income would produce a higher percentage and is not the standard lender calculation.
