How to use
Debt-to-income ratio compares recurring monthly payments with gross monthly income before tax. This calculator reports housing-only and total modeled ratios without assigning a universal lending cutoff, because underwriting standards vary by lender, product and jurisdiction.
- Enter gross monthly income before tax.
- Enter housing and other recurring monthly debt payments.
- Review housing ratio, total DTI and modeled payment total.
How it is calculated
Example
With gross income 6000, housing 1500 and other debt 600, the housing ratio is 25% and total DTI is 35%.
Important notes
Which obligations count toward DTI can vary. Use this as a general estimate and check the exact lender definition for a real application. The result is not an approval decision or financial advice.
