FAQ
What’s the difference between profit margin and markup?
Margin is profit divided by sales. Markup is (price − cost) divided by cost.
Does this calculator include fixed costs?
Yes. Add them in “Fixed costs (total)” to see profit and break-even units.
How are percentage fees calculated?
Fee % is applied to net sales (sales excluding tax/VAT), then added to total costs.
How does tax/VAT affect profit here?
Profit is based on net sales excluding tax. Tax/VAT collected is shown separately as informational.
What if break-even units shows “—”?
Your contribution per unit is zero or negative (e.g., price too low or fees too high), so a break-even point isn’t reachable with those inputs.
Can I calculate profit per unit?
Yes. The tool outputs profit per unit as total profit divided by units sold.
Is ROI the same as profit margin?
No. ROI here is profit divided by total costs; margin is profit divided by total revenue.
