Daily Interest Calculations based on days user as signed up.

[tasmontique]

Hi,

I am very green to asp and I am currently struggling with basic tasks in a starter kit that I am using.

Please help.

Here goes,
1.I want to calculate interest for users on a daily basis based on the date that they become a member.
2. I want to check when it is the 15 of the month and give an admin user the option to withdraw total earned for any given member.

3. Also if the user decides to withdraw principal on any given day of the month I want to be able to calculate the interest earned so far and withdraw accordingly.

4. Finally I want the interest calculation to be compounded every month.

eg Month (1) Principal $1000 plus 10% =1100(Principal = interest for first month)

Month (2) Principal $1100 plus 10% =1210(Month A total 1100 + 10% Interest) etc until user withdraws or cancels membership . I am assuming that it will be the reverse for a month when a loss occurs for interest.

I know that I will have to factor in 30 day months 31 day months feb 28 and feb 29.

Can someone please point me in the right direction of how to accomplish this with asp.net 2.0 visual basic

Thanks.
