A debt-to-income (DTI) ratio calculator shows how much of your monthly income goes to debt payments. Lenders use DTI to decide whether you can afford a new loan, especially a mortgage. Enter your monthly debt payments and your gross monthly income, and it calculates your ratio.
The formula is: DTI = total monthly debt payments ÷ gross monthly income × 100. Debts typically include rent or mortgage, car loans, student loans, credit card minimum payments and personal loans. For example, if your debts total $1,800 a month and you earn $5,000 before taxes, your DTI is 36 percent.
What do lenders look for? Many prefer a DTI around 36 percent or lower, though some loan programs allow higher ratios with strong credit or savings. Lenders often look at two numbers: the front-end ratio, which includes only housing costs, and the back-end ratio, which includes all debts. Requirements vary by lender and loan type.
How to lower your DTI: pay down balances, especially high-interest credit cards; avoid new debt before applying for a loan; and increase income where possible. Refinancing to a lower payment can help too. Remember that DTI uses gross income, not take-home pay, so your actual budget may feel tighter than the ratio suggests.
