vatcalc (version 2.0 Windows 95, 98, 2000, XP, Vista, Windows 7, Windows 8, Windows 10 (32bit and 64bit compatible)

vatcalc is a very simple, lean vat calculator. Its powerful though as you can change any value in any of the boxes and the figures update with all the correct values.

You can enter a figure in the vat inclusive box and find the vat component as well as the vat exclusive price, you can even just enter the vat to find what the inclusive and exclusive values are.

Any vat rate you entered will be kept for the next time the program opens (by default it starts at the current rate of 20%, if you do need to work out the lower rate of vat then simply change the value in the vat rate box. You can purchase vatcalc from the shop section of this website.

To use download the zip file from the link in the email sent once you have paid and extract the enclosed folder to your desktop or other place, double clicking on the enclosed vatcalc.exe starts the program.

You should get a standard system security warning box at some point after downloading or before running for the first time, allow the program to be extracted – your antivirus software should warn you if there is a problem. If you wish to keep your desktop tidy you can place the vatcalc folder elsewhere on your system and then drag vatcalc.exe to your START button (bottom left of your screen), this will make a shortcut to the program on your START menu. The file “vatrate.txt” in the same older as the program is a way of saving the last vat rate used without interfering with the windows registry, this program treads lightly. I use it every month when preparing my vat accounts to reverse engineer the vat amounts from retail prices, hope you find it useful too, if you have any comments I would be pleased to hear them.
