Whether you’re borrowing money or saving it, compounding interest can be your best friend—or your worst nightmare. It all depends on which side of the equation you’re on.
Let’s break down what compounding interest really means, when it applies, and how you can use it to your advantage (or avoid getting burned).
🧊 What Is Compounding Interest?
Compounding interest means you’re paying or earning interest on both the original amount and the interest that’s already been added. It’s like stacking bricks: the taller the stack gets, the faster it grows.
Here’s a simple example:
- You borrow $100, and your interest is 10%.
- After one cycle, you owe $110.
- If you don’t pay it off, the next interest charge applies to the $110, not the original $100.
- You now owe $121, and it keeps growing from there.
🌀 How Often Does Interest Compound?
It varies based on the type of credit account or loan. Common compounding schedules include:
- Daily (most credit cards)
- Monthly (some personal loans)
- Quarterly or Annually (some savings/investment accounts)
The more frequent the compounding, the faster the debt grows. Credit cards are particularly aggressive with daily compounding.
💰 Is Compounding Always a Bad Thing?
Nope. It can work in your favor when you’re saving or investing.
For example, if you invest $1,000 and earn 5% annual interest that compounds yearly:
- Year 1: $1,000 → $1,050
- Year 2: $1,050 → $1,102.50
- Year 3: $1,102.50 → $1,157.63
... and so on.
The longer you leave your money untouched, the more powerful compounding becomes. That’s why starting early is key when it comes to investing or saving.
