Debt-to-Income Ratio, Explained Simply

Your debt-to-income ratio is the share of your monthly income that goes toward paying debts, written as a percentage.

The math is simple. Add up your required monthly debt payments, divide by your gross monthly income (that is income before taxes), and turn it into a percentage. If your debts eat $1,500 a month and you make $5,000 a month, your ratio is 30 percent. Lenders lean on this number because it tells them, at a glance, how much room you have left to take on more.

This matters because it can decide whether you get approved for a mortgage, a car loan, or a decent rate. Most mortgage lenders want to see a total ratio at or below 43 percent, and many prefer under 36 percent. Climb higher than that and lenders start to worry you are stretched too thin, so they either say no or charge you more to cover their risk.

Here is a real-dollar example. Say you bring home $6,000 a month gross. You have a $1,200 rent payment, a $400 car loan, and $150 in minimum credit card payments. That is $1,750 in debt payments, which works out to about a 29 percent ratio. Healthy. Add a $500 personal loan and you jump to 37 percent, which starts to make lenders squint. Bringing that number down, either by paying off a debt or earning more, opens more doors.

Bottom line: A lower debt-to-income ratio means more borrowing power and better rates. Aim to keep it under 36 percent if you can.
