How to Calculate Your Debt to Income Ratio
Your debt-to-income ratio is an important measure of your financial health that lenders use to determine your eligibility for loans. If yours is too high, you may have trouble qualifying for loans and credit cards or might get stuck paying a high interest rate.
If you’re not familiar with debt-to-income ratios, read on to learn what they are and how to calculate yours.
What is a debt-to-income (DTI) ratio?
Your debt-to-income ratio is the amount of money you spend on debt payments (like student loans and credit) cards each month compared to your monthly pre-tax income. DTI is expressed as a percentage, and it’s often used by lenders to determine your ability to repay mortgages and other loans.
How do I calculate my debt-to-income ratio?
Calculating your debt-to-income ratio is easier than you think. Here’s how you do it by hand:
Step 1: Add up your monthly debt payments
To calculate your DTI, you’ll need to add up all of your monthly debt payments, including housing costs (rent or mortgage), car payments, student loans, child support, and credit card minimums.
Here’s an example calculation:
Add up your monthly debt payments: $1,000/mo. mortgage, $500/mo. in student loans, and a $250/mo. car payment.
$1,000 + $500+ $250 = $1,750 total debt payments
Step 2: Divide that number by your monthly income to get your DTI
Continuing the example calculation:
Let’s say that before taxes, you make $5,000/mo.
$1,750 / $5,000 = 0.35
Your DTI is 35%
Debt-to-income ratio for mortgage
Your debt-to-income ratio (also known as back-end ratio) is one of the main factors that determine your eligibility for a mortgage. If it’s too high, you may struggle to get approved because lenders see you as a risk. Most lenders prefer to work with borrowers whose DTI is 36% or less, but you may be able to qualify with a debt load as high as 43%.
There’s also a second ratio that lenders consider — your mortgage-to-income ratio (also known as front-end ratio). It compares your total housing costs, including your mortgage payments and property taxes, to your gross monthly income. It’s calculated by dividing your housing costs by your monthly income before taxes. Lenders use your mortgage-to-income ratio to figure out if you’ll be able to afford the home you want to buy. You’re most likely to be approved for a home loan if your mortgage-to-income ratio is less than 28%.
Debt-to-income ratio and credit
Your debt-to-income ratio doesn’t have an effect on your credit score because your income doesn’t show up on your credit report. But your credit utilization ratio, which is a measure of how much debt you owe compared to your current credit limit, is a big factor in determining your score. So if you want to maintain good credit, you should limit how much debt you take on.
Your debt-to-income ratio is also taken into consideration when you apply for personal loans and other forms of credit. If you have a high DTI, you may have trouble getting approved for loans or might receive a higher interest rate because lenders view you as a risk.
What’s considered a good DTI?
The maximum debt-to-income ratio for mortgages is 43%. But generally, debt-to-income ratios over 40% aren’t considered good — they’re viewed as a sign of financial stress. So if you want to maintain your financial health and qualify for loans with the best rates and terms, you should keep your DTI under 36%.
How do I lower my DTI?
There are two main ways to lower your debt-to-income ratio — increasing your income and paying down debt. You can bring in extra money by picking up a side hustle, taking on more hours at work, or asking your boss for a raise.
If you don’t have enough time to devote to a side job, you can try to reduce your debt instead. Take a look at your current expenses and see if there’s anything you can cut out. Use that extra money to pay down your debt, starting with the smallest loans first.
Even if you can’t find extra room in your budget or bring in more money, you may be able to lower your DTI by refinancing your loans. If you’re able to get smaller monthly payments, you’ll be able to lower your DTI without adjusting your budget.
The bottom line
Your debt-to-income ratio can affect your ability to qualify for everything from mortgages to credit cards, so keeping it in check is important. If you’re not sure what yours is, you should calculate it by adding up your debt payments and dividing them by your monthly income. If you discover your debt-to-income ratio is above or approaching 36%, you may want to work on lowering it by increasing your income or paying down some of your debt.
