About Compounding
Depending on how an investment is compounded it will have a different future value. For example, let's use the example of a $400 investment with a 5% return for 1 year.
Yearly Compounding
In this case, we add 5% to the investment after 1 year. So an investment of $400 will be worth $420 after 1 year.
Monthly Compounding
For monthly compounding, we divide the invest return by 12 and compound after each month. So a 5% interest rate equates to 0.4167% interest per month. This can be calculated by using this formula.
Investment x (1 + 5/12/100)12
The table below shows how monthly compound interest is calculated by month.

Weekly Compounding
For monthly compounding, we divide the invest return by 52 and compound after each week. So a 5% interest rate equates to 0.0962% interest per week. This can be calculated by using this formula.
