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.
