Calculation Results

Interest is the cost of borrowing money or the reward for lending/saving it. It is calculated in two primary ways:

Simple Interest: Calculated solely on the initial principal. The interest amount remains constant in each period.
Compound Interest: Calculated on the initial principal and the accumulated interest of prior periods. This causes the investment to grow faster over time.
