Measure monthly debt payments against income
DTI places mortgages, personal loans, auto loans, and other recurring debt payments against monthly income to show cash-flow pressure.
How to read the result
A higher ratio leaves less room for living costs, saving, and unexpected expenses, but lender thresholds are not universal.
Practical scenario: Run the calculation again after adding the estimated payment of a proposed loan to see the before/after effect.
What the estimate does not include
This is not an underwriting model and does not include credit scoring, collateral, income verification, or lender policy.
Treat the result as a range for further verification, then check the original contract, financial institution, or responsible authority before making a material financial decision.
