What is the compound interest formula for investments in a savings account with yearly compounding of interest?

Compound Interest = P * ([r/100] + 1) t 1

P stands for the original amount or your first deposited amount in the savings account.

r stands for the yearly interest rate of the savings account.

t stands for the period or total time of your investment, usually the number of years you are going to invest.

Now, if I will be investing 2,000 for 3 years with the annual interest rate of 4% how much will I profit if the interest gets compounded once a year?

Using the compound interest formula, we first put the correct inputs to their corresponding places in the formula.

? = 2000 ([4/100] + 1)3 1

? = 2000 ([0.04] + 1)3 1

? = 2000 (1.04)3 1

? = 2000 (1.124864) 1

? = 2249.728 1

? = 2248.728

Using the compound interest formula, you can have a total of $2248.73 with just three years of saving $2,000 and not doing anything.
