About Debt-to-Income Ratio Calculator
The Debt-to-Income Ratio Calculator compares entered monthly debt payments with gross monthly income. Annual income can be used to fill the monthly-income field, while rent or mortgage, car payments, student loans, credit-card minimums, and other debts form the total monthly debt.
The calculator produces one combined debt-to-income ratio. It does not calculate a separate front-end housing ratio.
Formula & Mathematical Calculation
Total monthly debt = Rent or mortgage + Car payments + Student loans + Credit-card minimums + Other debts
DTI (%) = Total monthly debt ÷ Gross monthly income × 100
Remaining income = max(0, Gross monthly income − Total monthly debt). Annual salary, when entered, is converted to monthly income by dividing by 12.
Calculation Example
Example: An annual salary of $78,000 fills monthly income as $6,500.00. With $1,500 rent or mortgage, $400 car payments, $250 student loans, $150 credit-card minimums, and $0 other debt, total monthly debt is $2,300. The DTI is 2,300 ÷ 6,500 × 100 = 35.4%, displayed as Good (36% - 43%).
