Debt-to-income ratio

Understand why dTI is a capacity indicator.

In this lesson

Debt-to-income ratio is part of Loan Cost Lab. This preview shows how credit-debt connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Today’s money mission

Imagine this situation: Monthly income: 180000 in local currency. Monthly debt payments: 54000 in local currency.

What you need to know

DTI is a capacity indicator. A 60% DTI means 60% of income is already committed — only 40% remains. A new loan payment reduces this further. Lenders see high DTI as low margin of error — any income disruption triggers cascading default.

Real-life example

Real-life money moment: Monthly income: 180000 in local currency. Monthly debt payments: 54000 in local currency. What is your DTI ratio and how do lenders interpret it? The key lesson is: DTI: 54,000/180,000=30%.
