How To Calculate Your Debt-To-Income Ratio For A Mortgage

How To Calculate Your Debt-To-Income Ratio For A Mortgage

There’s a lot that goes into the home buying process, especially if you’re a first-time home buyer. One criteria mortgage lenders use to assess your mortgage application is the debt-to-income ratio (DTI). Your debt-to-income ratio is a comparison of how much you owe (your debt) to how much money you earn (your income). The income you make before taxes (your gross income) is used to measure this number.

A lower debt-to-income ratio tells lenders you have a healthy balance between debt and income. However, a higher debt-to-income ratio indicates that too much of your income is dedicated to paying down debt. This could make some lenders see you as a risky borrower. While the DTI isn’t the only factor used to assess how much you can borrow, it’s still important to understand before you begin the home loan process.

What is a good debt-to-income ratio?

A debt-to-income ratio of 20{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550} means that 20{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550} of your income is going toward debt payments. This includes cumulative debt payments, so think credit card payments, car payments, student loans, personal loans and any other debt you may have taken on.

According to a breakdown from The Mortgage Reports, a good debt-to-income ratio is 43{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550} or less. Many lenders may even want to see a DTI that’s closer to 35{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550}, according to LendingTree. A ratio closer to 45{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550} might be acceptable depending on the loan you apply for, but a ratio that’s 50{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550} or higher can raise some eyebrows.

Simply put, having too much debt relative to your income will make it harder to qualify for some home loans. That’s why many common forms of debt — like student loan debt or credit card debt — can be a major barrier to homeownership.

Mortgage lenders want to make sure borrowers haven’t overextended themselves in terms of how much debt they can afford to take on. This is why having a high DTI could cause lenders to decline your mortgage application.

How do you calculate debt-to-income ratio?

The formula for calculating your DTI is actually pretty simple: You’ll just need to add up your total monthly debt payments and divide it by your total gross monthly income.

Let’s say you have a student loan payment, a car payment and a credit card payment that total to $1,000 per month. Your gross monthly income is $5,000. When we divide 1,000 (your debt) by 5,000 (your gross income), we get 0.2, which is 20{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550}. So in this case, your DTI is 20{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550}.

Mortgages and DTI

When applying for a mortgage, you should also consider all the costs that come with purchasing a home, including private mortgage insurance (PMI) (if you put down less than 20{ac23b82de22bd478cde2a3afa9e55fd5f696f5668b46466ac4c8be2ee1b69550}, homeowner’s insurance), property taxes, interest, lender fees, inspections, appraisals, closing costs and more.

Needless to say, it’s an expensive process. But you can make it a little more affordable by choosing a lender that offers ways to help you save. For example, Ally Bank doesn’t charge certain lender fees such as an application fee, origination fee, processing fee or underwriting fee. This can help you save some cash on the upfront process.

Bottom line

Taking on a mortgage is a hefty responsibility, so lenders want to make sure you aren’t biting off more than you can chew when it comes to your current debt responsibilities. This is why they calculate a debt-to-income ratio to judge how much of your income goes toward debt payments.

Of course, the DTI isn’t the only criteria a lender will look at, so don’t feel too discouraged if your DTI is a little higher than most lenders prefer. Calculating your DTI sooner rather than later will allow you ample time to pay down debt or increase your income so you can lower that DTI.
