Pat's VAT Refund Calculator is what it's called, a simple VAT calculator. Originally built for Germany, this app will work anywhere the price is in Euro.
Ever wonder if the VAT form is worth it? This app will not only calculate your refund but will also tell you if the form is worth it. Enter your total price and click Go. You can even add store discounts, if a price threshold has been reached. The USD to EUR exchange automatically updates from Yahoo Finance, if connected to the web. Give it a go, it's free...for now.
