Scenario guidance
When to use this
Use this when estimating how much of gross monthly income is already committed to debt payments.
Example scenario
A borrower is preparing for a loan conversation and wants a quick estimate of their current debt-to-income ratio.
Inputs that usually matter most
- Monthly debt payments, because they represent required recurring debt obligations.
- Gross monthly income, because the ratio uses income before taxes and deductions.
Common mistake to avoid
Do not mix net income with gross income if you are comparing the result with lender-style DTI calculations.
How to interpret the result
Use the percentage as a planning estimate, then verify which debts, income sources, and rules a lender or program actually uses.
Results are estimates for planning and education. They are not financial advice and lender rules can vary.
Formula
The calculator divides monthly debt payments by gross monthly income and converts the result to a percentage.
Example DTI
$1,800 in monthly debt payments and $6,500 in gross monthly income gives an estimated debt-to-income ratio of about 27.69%.
Frequently Asked Questions
Should rent be included in debt payments?
For a simple DTI estimate, include required debt payments. Housing treatment can vary by lender, product, and purpose.
What happens if income is zero?
The calculator shows the ratio as undefined because DTI cannot be calculated without positive gross monthly income.
