Debt Income Ratio

Debt Income Ratio =

Total monthly debt

Gross monthly income


The debt income ratio shows the total debt amount in proportion to net income. It shows what percentage of your income is being paid out in monthly debt payments for credit cards, loans, and mortgages.

Note: expanded calculation

Divide total monthly debt payments by gross monthly income


M&M company’s monthly credit card bills are $1,000, car loan payments are $500, and a monthly mortgage payment of $1,500. Their total monthly debt obligations equal $3,000. M&M’s annual income is $60,000, and their debt to income ratio:

Debt Income Ratio = $3000 / ($60,000/12) = .60 = 60%

This would be considered a high debt to income ratio


Lenders have varying maximum DTI ratios, but a general rule of thumb is to keep your overall debt-to-income ratio at or below 43%.

A low debt-to-income ratio makes it likely that you will be approved for a loan because it indicates that your monthly debt payments are a small percentage of your monthly income.

ROT: Rule of thumb
HA: Historical Average (organization’s historical average)
