Tips & tricks
- There's no reverse/target-margin mode — to find a selling price that hits a desired margin, calculate it yourself: Selling Price = Cost ÷ (1 − target margin as a decimal), then verify by entering both figures here.
- This calculates gross profit margin only, from Revenue and Cost — it has no fields for operating expenses, taxes, or interest, so it can't compute net profit margin.
- Markup and margin are shown side by side precisely because they're often confused — remember markup is profit ÷ cost, while margin is profit ÷ revenue.
- If Cost is left blank or entered as 0, Markup will show as 0% even though Gross Profit and Margin may still calculate — enter an accurate cost for a meaningful markup figure.
Frequently Asked Questions
What is the difference between profit margin and markup?
Profit margin = profit ÷ revenue × 100 (profit as a % of selling price). Markup = profit ÷ cost × 100 (profit as a % of cost). A 50% markup equals a 33.3% margin. They are NOT the same number — the calculator shows both side by side.
What is a good profit margin for retail businesses?
Grocery stores: 1–3%. Restaurants: 3–9%. Retail clothing: 50–60% gross margin. SaaS software: 70–80%. Margins vary enormously by industry — compare to industry benchmarks, not generic numbers.
How do I calculate profit margin from cost and selling price?
(Selling Price − Cost) ÷ Selling Price × 100 = Gross Margin %. For example, cost $40, sell for $60: ($60 − $40) ÷ $60 × 100 = 33.3% gross margin. Enter both figures and the calculator does this instantly.
What is net profit margin vs gross profit margin?
Gross margin only subtracts the direct cost of goods sold (COGS), which is what this calculator computes from your Revenue and Cost fields. Net margin subtracts ALL expenses including operating costs, taxes, and interest — this tool doesn't have fields for those, so it can't calculate net margin directly.
Can I use this to set pricing for my products by entering a target margin?
Not directly — there's no reverse mode where you enter a target margin % and get a suggested selling price. You can work backwards manually instead: Selling Price = Cost ÷ (1 − target margin as a decimal). For example, for a $40 cost and a 40% target margin: $40 ÷ (1 − 0.40) = $66.67.
