Power of Compound Interest
- Compound interest is interest calculated on both the principal and accumulated interest, leading to faster growth than simple interest.
- This causes earnings to increase each period because interest is earned on previously earned interest.
Compound Interest Real Examples
- A 20-year-old investing $10,000 at 7% interest can grow it to almost $150,000 in 40 years without adding more money.
- Adding $200 monthly at 6% over 30 years grows to $200,896, even though only $72,000 was deposited.
Compounding Beyond Finance
- Compound interest impacts economic growth and inflation, causing exponential effects over long periods.
- Small differences in growth or inflation rates lead to huge value differences after many years.
