Frequently asked questions

How is the debt-to-income ratio calculated?+

It divides your total monthly debt payments, such as rent or mortgage, car loans, student loans, and minimum credit card payments, by your gross monthly income, expressed as a percentage.

Why do lenders care about this ratio so much?+

It's a quick measure of how much of your income is already committed to debt obligations, helping lenders judge whether you can reasonably take on and repay additional debt without becoming financially overextended.

What is considered a healthy debt-to-income ratio?+

Many lenders view a ratio under 36% as healthy, with some allowing up to around 43-50% for mortgages depending on the loan program, while a ratio above that range generally signals reduced borrowing capacity and higher perceived risk.

Does this ratio include expenses like groceries or utilities?+

No, it only includes fixed debt obligations, not general living expenses. This is why a low debt-to-income ratio doesn't automatically mean you have comfortable monthly cash flow once all other bills are factored in.

Should I use gross or net income for this calculation?+

Standard practice, especially for mortgage lending, is to use gross monthly income before taxes and deductions, since that is the convention lenders use, even though your actual spendable income is lower.
