Using it at 12%
Explore why 72÷6=12 years at 6%.
In this lesson
Using it at 12% is part of The Rule of 72. This preview shows how interest-growth connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.
Think about this money choice
Imagine this situation: FGN Bonds offer 12% per year.
How it works
72÷6=12 years at 6%. 72÷12=6 years at 12%. Difference: 12−6=6 years faster. Doubling the rate halves the doubling time — a powerful demonstration of why rate matters.
Apply it to a real decision
