How to Calculate Your Debt-to-Income Ratio
Your debt-to-income ratio is one simple number that shows how much of your income is already spoken for. Here is how to figure it out and how to move it in the right direction.
The basic formula
Add up your monthly debt payments. Divide that total by your gross monthly income, which is your income before taxes. Multiply by 100 to get a percentage.
Example: if your monthly debt payments total $1,500 and your gross monthly income is $5,000, your debt-to-income ratio is 1,500 ÷ 5,000 = 0.30, or 30%.
What counts as a debt payment
Typically included are housing payments (rent or mortgage), auto loans, student loans, minimum credit card payments, personal loans, and child support or alimony. Everyday expenses like groceries, utilities, and phone bills are usually not included, though they still matter for your own budget.
What lenders look for
A lower ratio means more of your income is free for a new payment. Limits vary by lender and by loan type, so ask the lender you are working with what they require. As a general rule, the lower your ratio, the stronger your position.
How to improve it
- Pay down balances, starting with debts that have high monthly payments relative to what you owe.
- Avoid new debt in the months before you apply.
- Increase documented income where you can, and keep records that prove it.
Use it as a personal check, too
Even if you are not applying for anything, your debt-to-income ratio is a useful health check. Watching it fall over time is one of the clearest signs that you are moving toward financial freedom.
