I am creating an application with Visual Basic and I was wondering if anyone had some code that would allow the application to mathmatically calculate two values. I am making a mortgage calculator if you are wondering. It will be composed of several user entered forms: Loan Amount $: Interest Rate %: Length of Loan (Term): The result will be: Monthly Payment = Monthly Rate = here is the math: Monthly Payment: ( interest rate / ( 1 - ( 1 + interest rate) ^ Loan Length or Term)) Principal Monthly Rate: (1+ Interest Rate)^(1/12)-1 I need the user entered forms to do this math. Does anyone know of a code or tutorial that will help?
