Study Notes

Interest

Interest is related to savings accounts and is usually expressed as a percentage.
There are two main groups that interest usually falls into: simple interest and compound interest.

Simple Interest

Simple interest is calculated by applying the interest rate to the initial principal amount.
The interest rate is applied to the initial amount, not the accumulated interest.

Compound Interest

Compound interest is calculated by applying the interest rate to both the principal amount and any accrued interest.
Albert Einstein reportedly called compound interest the eighth wonder of the world due to its powerful and rapid growth.
Compound interest earns interest on both the principal and any accrued interest, leading to exponential growth.
