APR — annual percentage rate

Explore why aPR standardises the comparison.

In this lesson

APR — annual percentage rate is part of What Is Interest?. 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: Loan A: 2% per month. Loan B: 20% APR.

How it works

APR standardises the comparison. A monthly rate, weekly rate, or 'flat fee' can all be converted to APR. Always compare APR to APR — it prevents being misled by rates quoted in other periods.

Apply it to a real decision

Real-life money moment: A fintech ad says: 'Borrow at just 1.5% monthly.
