Use our Debt Optimizer to automatically calculate your DTI and find ways to lower your payments and improve credit score

To calculate your estimated DTI ratio, simply input your income and payments. If estimating what your DTI would be on a future home purchase, don’t include any rent you won’t pay in future. Please note this calculator is for educational purposes only and is not a denial or approval of credit. The accuracy of our DTI calculation is based on the accuracy and completeness of the information you provide. When you apply for credit, your mortgage lender may calculate your debt-to-income (DTI) ratio based on verified income and debt amounts that may differ from what you’d estimate, especialy if you’re self-employed or recently changed jobs. If you feel uncomfortable entering in any information, you can read our guide below and do the math offline at home!
Your debt-to-income ratio (DTI) is the percentage of your income that goes toward debt payments each month.

That’s all, don’t get thrown off by any complicated words lenders use. After your credit score, it’s probably the most important way lenders (especially mortgage lenders) determine how risky it would be to lend to you. Quickly see how your DTI looks with our calculator, or try our debt optimizer that calculates your DTI (along with ways you can quickly lower it).

What is a Debt-to-Income Ratio? And How Do You Calculate Yours?

Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes to any monthly obligations you owe such as debts and rent. Because this ratio takes into account all your debts and obligations, it is sometimes referred to as a “back-end” debt-to-income ratio by mortgage lenders. Lenders evaluate your financial situation with this DTI ratio precisely to figure out how much cushion there is in your monthly budget for emergency expenses and other shocks.


To calculate your debt-to-income ratio, sum up all your monthly debt obligations, plus mortgage payments and housing expenses. This includes personal loans, car loans, child support, student loans, and minimum payments on any revolving debt like credit cards.


Then you need to determine your monthly gross income before taxes. This includes all sources of regular income you and any coborrowers have if you’re figuring out your DTI for a future mortgage.


The final step in calculating your debt-to-income ratio is dividing your total monthly debt payments by your monthly (gross) income. To read this as a percentage, multiply it by 100, e.g. 0.39 is 39%

Sum up your total monthly “debt” payments. Anything fixed that you have to pay, such as:

  • Mortgage payments
  • Car loans
  • Student loans
  • Credit card payments
  • Personal loans
  • Property taxes, and property or mortgage insurance
  • Any child support or alimony

Sum up your monthly (household, pre-tax) income - including any regular and consistent government or pension payments like social security.

DTI = Debt Payments / Income
Example: if you have $2200 from Step 1 and $5000 in income from Step 2, your DTI is $2200/$5000 = 0.45 or 45%

If any of that sounds difficult, you can use our Debt Optimizer for an automated estimate of your debt to income. And if you’d like to dive deeper into an official definition there’s one here.
Other than your credit score, your debt-to-income (DTI) ratio is the most important factor most mortgage lenders consider to qualify for a mortgage. This is because the largest supporters of US mortgage markets: Fannie Mae, Freddie Mac, as well as FHA/VA loans, require certain DTI ratios.

A great debt-to-income ratio is under 36%. You shouldn’t have a problem getting denied for any mortgage with a debt-to-income ratio of 36% or less. Quite a few government loan programs, e.g. for borrowers with high credit scores, allow DTI to go up to 43% or even 50%.

Over 50%, the typically cheapest (government agency-sponsored) mortgages will no longer be available. There are still smaller, niche programs – often called “non-qualifying mortgages” or “Non-QM” because they don’t do as strict a job judging your ability to repay. But lenders for these more innovative products require other risk-reducing factors like a lower loan-to-value (LTV) ratio or higher credit score.

How Can I Lower My Debt-To-Income Ratio?

Your Debt-to-Income Ratio (DTI) is an important reflection of your financial health to lenders - we can easily calculate it for you as well as help you lower it. DTI gives you one view on how much safety cushion you have for unplanned expenses or changes in income. It’s also useful for buying a home, as a low DTI gives you access to the lowest cost sources of financing. Even if you don’t qualify for a standard mortgage today, we can help you qualify for a mortgage in the future by optimizing your debts and use of credit.
