FAQ

What is profit margin?

Profit margin is profit divided by revenue, shown as a percentage.

What’s the difference between margin and markup?

Margin uses revenue in the denominator (profit ÷ revenue), while markup uses cost (profit ÷ cost).

How do I calculate profit margin from price and cost?

Margin % = (Price − Cost) ÷ Price × 100. Add fees to cost if they apply per unit.

Can I include shipping and payment fees?

Yes—put them in “Extra fees (per unit)” so they reduce profit and margin automatically.

How do I find the selling price for a target margin?

Price = Unit cost ÷ (1 − target margin). Use “Find price” to compute it instantly.

What is the break-even price?

It’s the minimum price to avoid a loss, equal to cost per unit plus extra fees per unit.

Should I use gross margin or net margin here?

This tool is as accurate as the costs you include—add all per-unit costs for a net-like view, or only COGS for gross margin.
