In that case I might use ASP calling a VFP or VB com object. You could probably do the calculation right in the ASP page but then the user could use the view source feature of the browser and see the formula which I assume would defeat the entire purpose.

Well actually- ASP source is not viewable on the client because is it run on the server and translated to HTML before it ever hits the wire.

Running client side Javascript or VBScript would risk exposing the calculation, but client-side processing is different from ASP running on the server.
