What is the Debt-to-Income (DTI) Calculator?

The Debt-to-Income (DTI) Calculator measures what percentage of your gross monthly income goes toward paying debts. This is the exact metric lenders use to approve or deny loans.

It analyzes values such as loan amount, interest rate, term, monthly payment and returns insight through outputs like monthly obligation, total interest, payoff timeline, savings opportunity.

This structure helps you compare alternatives, understand trade-offs, and identify whether your current strategy is aligned with your goals.

Frequently Asked Questions

A DTI below 36% is generally considered excellent. If your DTI goes above 43%, most traditional lenders will not approve you for a mortgage.

DTI calculations strictly use your Gross Income (your income before taxes and deductions are taken out). This is why you must budget carefully, as your actual take-home pay is much lower.
