VAT Deluxe can quickly calculate VAT ( Value added Tax ), Net and Incl. amounts. The calculator has big keys which let you type easily.
With VAT Deluxe you just need to know one amount and the other amounts will be calculated.
VAT Deluxe can save two VAT-Amounts as presets. To do this simply type the VAT-Amount that you need into the VAT-Amount field and save the amount by doubletapping one of the V-Symbols. A single tap will recall the amount. Additionally the last used VAT-Amount will be saved, so you don't have to type it again after restarting VAT Deluxe.
