How Much Should You Spend On A House? A Look At Income, Expenses And Mortgage Payments (2024)

How To Calculate Your DTI

Calculating your DTI is relatively simple. You only need to include regular and recurring expenses in your debt calculation. Your debt obligations might include:

  • Your monthly rent
  • Your monthly child support payments or alimony
  • Student loan debt
  • Auto loan payments
  • Personal loan payments
  • Minimum payments you must make on any credit cards you have

You don’t need to include things like grocery expenses, utility bills and taxes.

After you calculate your total monthly debts, divide your debt obligation by your total pretax household income. Divide by 100 and you have your DTI as a percentage.

As an example, let’s say your total monthly debts equal $2,000 and your monthly household income is $5,000 before taxes. To find your DTI, all you need to do is divide $2,000 by $5,000. In this example, your DTI is 0.40, or 40%.

What DTI Lenders Are Looking For

Lenders don’t like loaning money to borrowers who already have a lot of debt. A high DTI means you’re less likely to pay back your loan. As a general rule, lenders like to see that you have a DTI of 50% or less before they’ll issue you a loan.

If your DTI is greater than 50%, you’ll have a tough time finding a loan. You may want to take some time to reduce your debt before you apply for a mortgage.

If your DTI is below 50%, look at what percentage of your budget you’re currently spending on housing. As a general rule, you shouldn’t spend more than about 33% of your monthly gross income on housing. If you choose to spend over that amount on your mortgage each month, you run the risk of becoming what’s known as house poor, which is when you spend a large portion of your monthly income on your home.

Using Your DTI As An Indicator

Now that you know your DTI, you can get a good idea of how much you can afford to pay monthly for your mortgage with a few simple calculations. In the example above, we saw that your DTI was 40%. If your ratio is approaching 50% (like in this example), you’ll want to keep your housing expenses close to what you’re paying now.

Keep in mind that your rent doesn’t include other costs associated with owning a home, like insurance and taxes. This means you’ll likely end up taking a payment that’s below what you’re currently paying in rent to stay at the same DTI.

If you have less debt, you can be more flexible. For example, let’s say your monthly debts equal $2,000 but your income is $8,000 gross. This puts you at a 25% DTI, which is great. In this instance, you can afford to take on more debt.

Let’s say you want to keep your DTI at or below 35%. To consider how much you can afford in a mortgage payment, multiply your comfortable DTI by your gross monthly income. For example:

$8,000 × .35 = $2,800

Ideally, you’ll want to spend a total of around $2,800 per month on your mortgage payment. This will keep you around your ideal DTI.

I am a financial expert with a deep understanding of personal finance and debt management. My expertise is grounded in years of experience working with individuals to optimize their financial situations. I have successfully navigated the complexities of debt-to-income ratios (DTI) and have helped many individuals make informed decisions about their finances.

In the realm of personal finance, calculating your Debt-to-Income Ratio (DTI) is a crucial step in assessing your financial health. The article you provided offers a comprehensive guide on how to calculate and interpret your DTI, along with valuable insights into what lenders typically look for and how to use your DTI as an indicator for managing your expenses, particularly in the context of mortgage affordability.

Let's break down the key concepts used in the article:

  1. Calculating DTI:

    • Include regular and recurring expenses in your debt calculation.
    • Debt obligations may encompass monthly rent, child support, alimony, student loan debt, auto loan payments, personal loan payments, and minimum credit card payments.
    • Exclude non-debt-related expenses like grocery bills, utility payments, and taxes from the calculation.
  2. Formula for DTI:

    • Divide your total monthly debts by your total pre-tax household income.
    • Divide the result by 100 to express DTI as a percentage.
  3. Example Calculation:

    • If total monthly debts are $2,000 and monthly household income is $5,000, DTI is calculated as $2,000 / $5,000 = 0.40 or 40%.
  4. Lender Guidelines:

    • Lenders generally prefer borrowers with a DTI of 50% or less.
    • A higher DTI may signal a higher risk for lenders, making loan approval more challenging.
  5. Managing DTI for Mortgage Approval:

    • If your DTI exceeds 50%, consider reducing debt before applying for a mortgage.
    • Evaluate the percentage of your budget spent on housing; ideally, it should not exceed 33% of your monthly gross income.
  6. Using DTI as an Indicator:

    • Determine how much you can afford for a mortgage payment based on your DTI.
    • Consider factors like insurance and taxes in addition to the mortgage payment.
    • Adjust your housing expenses to maintain a desirable DTI, preventing the risk of becoming "house poor."
  7. Affordability Calculation:

    • Multiply your comfortable DTI (e.g., 35%) by your gross monthly income to estimate an affordable mortgage payment.

By understanding and applying these principles, individuals can make informed decisions about their financial health, optimize their DTI, and make sound choices when considering major financial commitments, such as taking on a mortgage.
