The 28/36 rule

Understand why the 28/36 rule is a debt stress buffer.

In this lesson

The 28/36 rule 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: 150000 in local currency. Rent: 50000 in local currency (33%). Loan repayments: 30000 in local currency. Total debt: 80000 in local currency (53%).

What you need to know

The 28/36 rule is a debt stress buffer. If housing consumes 28% and all debt 36%, approximately 64% of income remains for food, savings, and emergencies. Exceeding these ratios means any income disruption triggers default — the ratio is a resilience threshold.

Real-life example

Real-life money moment: Monthly income: 150000 in local currency. Rent: 50000 in local currency (33%). Loan repayments: 30000 in local currency. Total debt: 80000 in local currency (53%). Are you within the 28/36 rule? The key lesson is: 28/36 rule: housing ≤28% of income, total debt ≤36%.

Quiz preview

The 28/36 rule says housing costs should not exceed:

10% given the circumstances
28% of gross income
100% in most everyday cases
50% under normal conditions

Monthly income: 150000 in local currency. Rent: 50000 in local currency (33%). Loan repayments: 30000 in local currency. Total debt: 80000 in local currency (53%). Are you within the 28/36 rule?

Yes — both are under 50% in most everyday cases when planning ahead in practical terms
The rule does not apply in your country in most everyday cases in this situation
Partially — housing is borderline in practical terms
No — housing exceeds 28% (33%) and total debt exceeds 36% (53%). Both thresholds breached — significant financial stress risk
