FAQ

Frequently asked questions

How do you calculate profit margin?⌄

Gross profit margin = (Net revenue − Cost of goods) / Net revenue × 100. Net revenue is the selling price excluding VAT. Net margin additionally subtracts shipping and fulfilment costs.

What is the difference between margin and markup?⌄

Margin is profit divided by selling price. Markup is profit divided by cost. A 50% markup equals a 33.3% margin.

How is break-even quantity calculated?⌄

Break-even quantity = Fixed costs / Profit per unit. It is the number of units you must sell to cover your fixed costs at your current margin.

Should I use my selling price including or excluding VAT?⌄

If you are VAT-registered, margins are computed on the price excluding VAT. Our calculator lets you toggle between including and excluding VAT and handles the conversion automatically.
