some help plz

hi,

im currently creating a retirement income forcaster. which will help the user see how they can reach there desired income per month they want after retirment

the user will input the years(start and end) they will work and how much they will earn each month.

and from this information it needs to calculate the monthly investments needed (from thier wage each month) to reach the desired income in retirement.

im creating this in a console application.

i have done the first parts but was stuck on how the program will calculate the investements needed for them to reach their desired income. so how much the user will have to invest eah month so they can reach there desired income.

could anybody help me with this thanks.

The user will have to enter the interest rate of the investment and then you can use a compound interest calculation to determine the required payments.

Excel has a lot of functions that migh be useful.

Note also that the members of the Microsoft.VisualBasic.Financial module might also be useful. This is one of those cases where VB Runtime functions can add value.
