The concept of future value is related to time value of money. For example, if you deposit your money in a bank as a savings account or a fixed deposit account for a certain period of time, you will earn a certain amount of money based on the compound interest computed periodically, and this amount is added to the principal if you continue to keep the money in the bank. Interest for the following period is now computed based on the initial principal plus the interest (the amount which becomes your new principal). Subsequent interests are computed in the same way.
In our Future Value Calculator, we are given a known present value and we want to calculate how much will be the future value after a numbers of years compounded upon a certain interest rate. In that example, we use the formula
FV = PV * (1 + i / 100)n
To calculate the future value. However, in this example, we already has a target future value in mind and we wish to know how much money we need to invest to achieve the target based on a certain interest. Though we still can employ the same basic formula, this time we preferred to use the VB built-in present value function, or PV.
The syntax of the PV function is
Nper=The length of period (Usually number of years)
*Due= 1 if payment due at beginning of a period and Due=0 if payment due at the end of a period.
