Explore why interest rate = risk premium.
In this lesson
Why lenders charge interest 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.
Today’s money mission
Imagine this situation: A bank lends 100000 in local currency to a business.
What you need to know
Interest rate = risk premium. If 1 in 10 high-risk borrowers default, the lender needs the other 9 to pay enough to cover the loss plus profit. Higher risk = higher rate.
Real-life example
Real-life money moment: Inflation is 15% per year. A bank offers savings at 8%. A friend offers to borrow your 20000 in local currency and repay in 1 year.
Progress Penguin connection
Open Requests and look at the gap between when you submit a withdrawal and when it is approved. A lender faces a similar gap — they give you money now and wait for repayment. Interest is the fee the lender charges for that waiting period. The wait is real; so is the fee.
