Calculator Description
The Debt to Income Ratio Calculator calculates the percent of your gross monthly income that pays for existing recurring monthly debts and expenses. To find your debt-to-income (DTI) ratio, input your gross monthly income and qualified monthly monthly debt payments. You can use the results to measure the size of your debt as against your income while exploring loan options.
Please be advised that DTI is only a part of your overall financial condition, and it does not suggest that you qualify for a loan, special interest rate, specific mortgage, credit product or any other loan offer.
How to Use the Debt to Income Ratio Calculator
Enter your gross monthly income and the monthly debt obligations that should be included in the calculation.
- Enter gross monthly income: Use income before taxes and other payroll deductions. If you receive income weekly, biweekly, or annually, convert it to a monthly amount before entering it if the calculator requires monthly income.
- Enter monthly housing costs: Be sure to add your monthly payment amount to whatever you are using to run the DTI, again, if the calculator uses this. In this situation we are talking about a mortgage, but that would generally involve things such as interest, principal, insurance, property taxes.
- Enter monthly debt payments: Add in any recurring payment debts Auto payments, Student Loans, Credit Card Bills, Personal loan payments, or any other qualifying debt depending on the calculation you are doing.
- Review the calculated DTI: The figure given is presented as a percentage which indicates what fraction of gross monthly income is tied up in paying the debt installments mentioned above.
Provide the same time frame for each entry. Don't mix yearly income and monthly debt payments without first converting the annual income to monthly.
How the Debt to Income Ratio Calculator Works
A Debt to Income Ratio Calculator works by taking your monthly qualified debt payments, adding them together, dividing that number by your gross monthly income and then multiplying that percentage by 100. That results in your total monthly payment amounts towards your included debt obligations as a percentage of your monthly income prior to tax.
For example, if gross monthly income is $8,000 and qualifying monthly debt payments total $2,400, the DTI is 30%.
However the precise debts included in a calculation of your DTI may differ depending on the context of your request and your lender or product for whom calculation it pertains. Personal budget accounting may exclude certain loan varieties from a calculation which are deemed unacceptable to the lending bank's security review.
Debt to Income Ratio Calculator Formula
The basic DTI formula is:
DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100
- Total Monthly Debt Payments = qualifying recurring monthly debt obligations
- Gross Monthly Income = income before taxes and other deductions
- DTI = debt-to-income ratio expressed as a percentage
For example, with $2,400 of monthly debt payments and $8,000 of gross monthly income:
DTI = ($2,400 ÷ $8,000) × 100 = 30%
This is a ratio, not cash on hand for immediate use, after paying all bills, food, taxes etc
Debt to Income Ratio Calculator Example
Assume a U.S. borrower earns $96,000 per year in gross income and has the following recurring monthly debt obligations:
- Auto loan: $450
- Student loan: $300
- Credit card payments: $250
- Personal loan: $200
Gross monthly income: $96,000 ÷ 12 = $8,000
Total monthly debt payments: $450 + $300 + $250 + $200 = $1,200
DTI: ($1,200 ÷ $8,000) × 100 = 15%
In this example, 15% of total gross monthly income is the debt payments incorporated into the debt-to-income calculation. If a possible mortgage payment were to be included, the calculated DTI would be greater.
Understanding Your DTI Result
The DTI percentage indicates the proportion of your gross monthly income that is dedicated to the debt obligations counted in the DTI calculation. The lower your DTI, the less of your gross income is dedicated to debt and the higher your DTI, the more of your gross income is dedicated to debt.
It’s important not to think of DTI as an “all-purpose score.” It can be calculated in multiple ways, with varied methods of defining “debt,” “income,” and varying lending guidelines and underwriting practices.
| DTI Result |
What It Indicates |
| Lower DTI |
A smaller portion of gross monthly income is committed to included debt payments. |
| Moderate DTI |
A meaningful portion of gross income is allocated to debt obligations. |
| Higher DTI |
A larger portion of gross income is committed to recurring debt payments. |
The following table is not a standard borrower qualification policy in the true sense and should just be an interpretative of a lenders understanding rather than exact criteria for qualifying. Your available borrow capacity will vary per individual lender, product type, credit profile, income and assets, etc.
Front-End DTI vs. Back-End DTI
Two terms commonly appear in mortgage discussions: front-end DTI and back-end DTI.
Front-end DTI only includes mortgage-related costs and is then divided by an applicant’s monthly gross income. Alternatively, there's the back end of the DTI formula, which accounts for mortgage costs and any other regular, eligible debts.
Different definitions may apply lenders can apply different underwriting rules from different lenders, and this cannot be taken that it is a precise 100% result what a lender.
What Counts as Monthly Debt for DTI?
Depending on the calculation, commonly considered recurring debt obligations may include:
- Mortgage or proposed housing payments
- Auto loan payments
- Student loan payments
- Credit card obligations
- Personal loan payments
- Other recurring installment debt
- Certain legally required recurring obligations when applicable to the calculation
Though not all bills have a place in the DTI calculation, for instance: some expenditures will fall under everyday living not loans; Utilities Grocery Expenses Household Goods Entertainment Expenses are not included in these calculation of DTI.
How a New Loan Can Change Your DTI
New Loan Could Affect DTI Your desired new loan can affect your DTI: The estimated monthly loan payment might be applied toward what’s currently defined as a qualified debt payment. Consider a scenario for a lender with the borrower needing to meet this guideline: A potential buyer has monthly debt payments amounting to $1,500 and a monthly gross income of $7,500 (a current DTI of 20%).
If a proposed loan adds a $1,000 monthly payment, the combined monthly debt becomes $2,500 and the resulting DTI would be approximately 33.3%.
Let's try an example of how calculating a pre-new-debt DTI can useful give us a picture of how adding another monthly payment will alter the ratio of debts to income.
Factors That Can Affect Your DTI
Gross Monthly Income
DTI will decrease, as a percentage, when all the qualifying debt payments stay the same. Apply the same income definition the online DTI calculator use; instead of taking gross income into account for standard DTI calculation, use your take-home pay.
Monthly Debt Payments
An increase in recurring payments on debt results in an increase in the debt-to-income ratio if income stays constant. Paying down or paying off the qualifying debt reduces the amount of monthly debt to be included in the calculation.
New Borrowing
Taking on an additional loan or other qualifying debt can increase DTI if the new monthly obligation is included in the calculation.
Income Changes
A Change in Gross Monthly income affects your DTI, but the only reason it would would affect is the value of your debts (which will stay the same). You must either use or actual number and not an idealized or hopefull estimation.
DTI and Credit Utilization Are Different
Debt-To-Income Versus Credit Utilization Although they seem similar, Debt-to-income ratio and credit utilization are not even close in the slightest in this regard. Debt-to-income relates monthly debt payments to gross monthly income while credit utilization relates the balances to the limit.
One could be one where someone has a relatively low DTI with high utilization and the opposite case, therefore do not use these interchangeably.
Common Mistakes to Avoid
- Using take-home pay: Standard DTI calculations generally use gross income rather than after-tax income.
- Mixing annual and monthly figures: Convert income and debt payments to the same time period.
- Entering debt balances instead of payments: DTI is based on recurring monthly debt obligations, not simply the total amount owed.
- Forgetting a recurring debt: Leaving out an applicable payment can make the calculated DTI lower than the result using all relevant obligations.
- Adding ordinary living expenses as debt: Not every household expense is classified as a debt obligation.
- Assuming every lender calculates DTI identically: Debt definitions and underwriting methods can differ.
- Ignoring a proposed loan payment: When evaluating a new borrowing scenario, include the proposed payment if the calculation is intended to show post-loan DTI.
- Treating DTI as an approval guarantee: A DTI calculation cannot determine whether a lender will approve a loan.

How to Lower Your Debt-to-Income Ratio
A DTI percentage can decrease when qualifying monthly debt payments decrease, gross monthly income increases, or both occur at the same time.
- Reduce recurring debt payments: Paying off a qualifying debt can remove its monthly obligation from the calculation.
- Avoid unnecessary new debt: Additional qualifying monthly payments can increase your DTI.
- Increase income when possible: A higher qualifying gross monthly income can reduce the ratio when debt payments remain unchanged.
- Review your existing obligations: Make sure the calculator includes accurate current payments rather than outdated amounts.
- Test different scenarios: Use the calculator to see how changes in income or monthly debt payments affect the resulting percentage.
DTI for Mortgage Planning
DTI comes up on most conversations about house payment qualification since a presented home payment, once calculated into your overallmonthly debtswill make a house affordabl e,or a purchase transaction unattainable, in the eyes of lenders. To apply for a mortgage, your calculation would be,Using the income and Debt payment definitions for this mortgage simulation:
It is very important for our clients to realize that the DTI for mortgage has to be viewed as only one component of the total affordability for a purchase. Homeowners insurance, property taxes, homeowners maintenance, utilities, closing costs, reserve funds, and any of their other personal household living expenses will impact the total homeownership cost.
Gross Monthly Income Conversion for DTI
Convert your income if it is not given on a monthly basis. For instance, this is what you should use to convert your weekly income to monthly. Choose the period that corresponds to your calculator.
| Income Frequency |
Example Income |
Approximate Monthly Equivalent |
| Annual |
$96,000 |
$8,000 |
| Monthly |
$8,000 |
$8,000 |
| Weekly |
$2,000 |
Approximately $8,667 |
| Biweekly |
$4,000 |
Approximately $8,667 |
This conversion can actually be more than just simple four or two multiplication if you're dealing with a weekly and biweekly income because there are more than just 26 occurrences of biweekly payouts each year and more than 4 weeks each month. To perform accurate conversions, it helps to annualize your pay first and then divide by 12 if it fits your conversion goal.
DTI Calculation With Multiple Debts
Add the qualifying portion for all debts of qualifying type if one is found, prior to division.
For example, suppose gross monthly income is $7,500 and monthly qualifying payments are $350 for an auto loan, $250 for student debt, $150 for a personal loan, and $300 for credit card obligations.
Total monthly debt: $350 + $250 + $150 + $300 = $1,050
DTI: ($1,050 ÷ $7,500) × 100 = 14%
This is, the calculation is based on the date to date and not on the double adding of each bank balances.
