GP Calculator Pro
The industry-standard tool for hospitality operators to calculate perfect margins, forecast price hikes, and protect their profit.
Rule #1: Net Figures
All cost prices must be entered EX-VAT (Invoice price). The calculator handles all VAT logic for your sell prices automatically.
Rule #2: Smart Rounding
Sell prices are automatically rounded up to the nearest 10p. This subtle shift helps protect your GP against minor fluctuations.
