How Simple Interest Works
Unlike compound interest which earns return on top of return, simple interest is calculated strictly on the original principal deposit value. The mathematical formula is simple and straightforward:
$$I = P \times r \times t$$
Where $I$ is Interest, $P$ is Principal, $r$ is Annual Interest Rate, and $t$ is Duration in Years.
