Compound interest is a financial calculation method that not only calculates the interest generated by your principal but also adds these interests to the principal to calculate new interest, creating a snowball effect.
FV (Future Value): The expected value of your investment at a future point in time.
PV (Present Value): Your current investment amount or principal.
i: Annual interest rate or expected annual return rate.
n: Investment period, usually in years.
Example: Principal 100, annual interest rate 20%.
First Year | Second Year | Third Year | |
---|---|---|---|
Compound interest | 100 * (1+20%) = 120 | 120 * (1+20%) = 144 | 144 * (1+20%) = 173 |
Simple interest | 100 + (100*20%) = 120 | 120 + (100*20%) = 140 | 140 + (100*20%) = 160 |
From this example, we can see that the effect of compound interest strengthens over time. The investment return in the second year is 4 more than the first year, and the third year is 13 more than the second year. This is the power of compound interest - your investment returns get better and better over time.
