Interest Rates: Simple vs. Compound
It's important to differentiate between simple and compound interest. Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus any accumulated interest. Compound interest leads to exponential growth over time. You can find tools online to also calculate compound interest.
You should use the simple interest formula A = P(1 + rt) to calculate non-compounded interest plus principal on a savings amount. The interest earned is not added back into the principal balance for subsequent interest calculations. /blog/what-is-simple-interest
