What's the difference between margin and markup?

Margin is profit ÷ selling price. Markup is profit ÷ cost. A 50% markup is only a 33% margin — confusing them will systematically underprice you.

Does this include VAT/sales tax?

No — enter net figures (ex-tax) throughout. Add VAT/GST on top of the selling price separately.

What margin should I aim for?

Physical products often target 40–60% gross margin to cover fulfilment and overheads; digital products 80%+; food service 60–70% food margin.
