Understanding Compound Interest

What is Compound Interest?

Compound interest means earning interest on both your original money AND the interest that money has already earned. It's like a snowball rolling downhill - it starts small but picks up more snow (money) as it goes!

Simple vs Compound Interest

Simple: $100 at 10% = $10 per year forever
Compound: $100 at 10% = $10 first year, then $11, then $12.10...

The Magic Formula

A = P(1 + r/n)^(nt)

A = Final amount

P = Principal (starting amount)

r = Interest rate

n = Compounding frequency

t = Time in years
