How DTI is Calculated
To use the calculator, enter all your recurring monthly debt payments—such as car loans, student loans, personal loans, minimum credit card payments, and current mortgage or rent. Then, input your gross (pre-tax) monthly income.
The tool divides your total monthly debt by your gross monthly income and multiplies the result by 100 to express your DTI ratio as a percentage.
For example, if your monthly debt is $1,500 and your income is $5,000, your DTI ratio would be 30%. Most lenders prefer a DTI ratio below 36%, with no more than 28% going toward housing expenses alone.
