Explore why interest is the price of borrowed money.

In this lesson

Loan interest explained is part of Interest Costs Borrowers. 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: You borrow 20000 in local currency at 25% per year for 2 years.

How it works

Interest is the price of borrowed money. Time plus rate equals extra cost. There is no such thing as free borrowing from a regulated lender — interest is always the price.

Apply it to a real decision

Real-life money moment: Loan A: 10000 in local currency at 20% APR for 1 year. Loan B: 10000 in local currency at 15% APR for 2 years.
