Calculate profit, margin %, markup %, and optional break-even units from cost and selling price. Free browser profit margin calculator—no login; pure local math for freelancers, product sellers, and service quotes.
Profit margin divides unit profit by the selling price: (sell − cost) ÷ sell × 100. Markup divides the same unit profit by cost: (sell − cost) ÷ cost × 100. A $40 cost and $100 price is 60% margin and 150% markup. Confusing the two underprices or overpromises when talking to suppliers or clients.
Enter unit cost and selling price. The tool shows unit profit (sell − cost), margin % on price, and markup % on cost. Optional fixed costs divide by contribution per unit (default sell − cost, or your own contribution input) to estimate break-even units. All values are calculated in your browser only.
Break-even units = fixed costs ÷ contribution per unit. Contribution defaults to sell − cost. If variable costs differ (packaging, payment fees), enter that contribution explicitly. Example: $2,000 fixed costs and $20 contribution → 100 units before covering fixed costs. This is planning math, not tax advice.
Yes. Treat cost as delivery cost (subcontractors, stock tools, software per job) and sell as quoted price. Pair with Freelance Rate Calculator when you need hourly floors from income goals, then stress-test quotes here for margin targets (many agencies hold 40–60% gross on services).
The calculator rejects sell below cost and shows an error—you cannot report a positive margin when pricing creates a unit loss. Raise price, cut cost, or deliberately run a loss leader outside this tool.
No. Enter cost and price in the same currency. Use Currency Converter on Power Tools when landed cost is in one currency and list price in another, then paste normalized numbers here.
No. Cost, price, and fixed costs never leave your browser tab. Safe for unreleased SKUs and client retainers.
Percentage Calculator offers general % math plus quick margin/markup modes. This dedicated profit margin calculator emphasizes pricing workflows: labeled COGS vs sell, markup, and optional break-even units on fixed costs for side hustles and product lines.
