Compare markup and gross profit margin, or calculate the VAT-inclusive selling price needed to hit a target gross profit margin.
Markup and margin are not the same thing.
Markup compares profit to cost. Margin compares profit to the selling price excluding VAT.
For VAT-registered hot food businesses, VAT must be removed before calculating true gross profit margin.
Required selling price mode works backwards from your cost and target gross margin to suggest the selling price including VAT.
