<h3>What is simple interest and compound interest?</h3>
Simple interest rate is the interest that is paid only on the principal portion of a loan. This means that the debtor does not pays interest on the interest rate already accrued. This differs from compound interest where the debt holder pays interest on the principal and the interest rate already accrued
<h3>What is the compound interest?</h3>
The formula for calculating future value:
FV = P (1 + r)^n
- FV = Future value
- P = Present value
- R = interest rate
- N = number of years
2000 x (1.06)^12 = $4024.39
Compound interest = $4024.39 - $2000 = $2024.39
<h3>What is the simple interest? </h3>
Simple interest = principal x time x interest rate
2000 x 0.08 x 12 = $1920
