Calculating the VAT

[junied32167]

I need help working out the VAT of my program.

Console.WriteLine(" The total cost of your expenses with VAT is" & FormatCurrency(cost + cost2 * 0.2))

Based on PEMDAS your math is Multiplying 0.2 with "cost2" and then adding "cost".

Assuming you are adding the two costs together and then the VAT is 0.2 you will want to do the following:

Add all costs together:
subtotal = cost+cost2

Find the VAT of subtotal:
vat = subtotal * 0.2

Add VAT to subtotal:
total = subtotal + vat

Apply those steps to your code.

Depending on each country this will operate, vat value must be rounded or trimmed.
Usually you round by 2 decimal places the "liquid total" value.

Could you also explain how I should code the program to allow the user to view details that are calculated later in the program. I have made a menu for my program but I don't know how to show details that are coded later on in the program. Basically the VAT rate has to be shown at the begging of the program if the user selects a certain option from my menu

just write the code to the click event of radio button . if specific condition is achieved show the message at the lable1.caption='what you want to show' that is the way to handle the things .

If RadioButton1.Checked = True Then
 
 Method()
 label1.caption='vat rate according to what you want

ElseIf RadioButton2.Checked = True Then

 Method2()
label2.caption="what you want to display'
End If
