If you invest $10,000 today and earn 7% per year, how much total interest will you make in 20 years? How much is simple interest and how much is due to compounding?
Simple Interest:
Simple interest earned for 20 years = Investment * Rate * 20
= 10000 * 7% * 20
= 14000
Compound interest:
Compound interest earned over 20 years = Investment * (1+ Rate)^20 - Investment
= 10000 * (1+7%)^20 - 10000
= 38696.84 - 10000
= 28696.84
Interest earned due to compounding = Total compound interest - SImple interest
= 28696.84 - 14000
= 14696.84
