Profit Margin & Markup Calculator
This free profit margin calculator helps business owners, product managers, and pricing analysts instantly compute gross margin, markup percentage, and gross profit from any two known values — cost, revenue, or margin %. The built-in breakeven calculator shows how many units you need to sell to cover your fixed costs.
How to Use the Margin & Markup Calculator
- Select which two values you already know using the radio buttons: Cost + Revenue, Cost + Margin %, or Revenue + Margin %.
- Enter your two known values. The third field is computed automatically and labelled "computed".
- Results update instantly: Gross Profit, Gross Margin %, Markup %, and Revenue are all displayed.
- A formula box shows the exact calculation with your figures — copy it for use in a report or spreadsheet.
- Switch to the Breakeven tab, enter your Fixed Costs, Variable Cost per Unit, and Selling Price to find breakeven units and revenue.
Margin vs Markup — The Key Difference
Margin and markup use a different denominator. Using the same $100 cost and $150 selling price:
Margin % = (Revenue − Cost) ÷ Revenue × 100 = ($150 − $100) ÷ $150 × 100 = 33.3%
Markup % = (Revenue − Cost) ÷ Cost × 100 = ($150 − $100) ÷ $100 × 100 = 50%
A 50% markup only produces a 33.3% margin. Quoting the wrong one to a client or buyer is one of the most common — and costly — pricing errors in business.
The Breakeven Formula
Breakeven Units = Fixed Costs ÷ (Selling Price − Variable Cost per Unit)
The denominator — the contribution margin per unit — is the amount each sale contributes toward fixed costs. Once you have sold enough units to cover all fixed costs, every additional sale is pure profit.
Key Features
- Three input modes: enter any two values and the third is calculated — no manual formula required.
- Gross Profit, Gross Margin %, Markup %, and Revenue all shown simultaneously.
- Step-by-step formula display with your actual numbers substituted in.
- Breakeven tab: units to break even, breakeven revenue, and contribution margin percentage.
- Copy result button sends the full formula text to your clipboard.
Use Cases
Set the Right Selling Price for a New Product
Enter your unit cost (COGS) and your target gross margin percentage in Cost + Margin % mode. The calculator tells you the exact minimum selling price needed to hit that margin — no guessing or backward spreadsheet work.
Audit Pricing Across a Product Catalogue
Enter cost and current selling price for each product to see whether each line item is meeting your target margin threshold. Products with thin margins can be flagged for price adjustment or cost reduction.
Prepare a Business Plan or Investment Pitch
Use the Breakeven tab to calculate the minimum monthly unit sales needed to cover your fixed overhead. A clear breakeven figure is one of the first questions investors and bank managers ask when reviewing a new business proposal. Pair the margin figures with a full return on investment analysis to show the complete financial picture.
Evaluate a Discount Without Eroding Profit
Enter the post-discount selling price and your cost to see what margin a promotional price leaves. A 20% sale discount can easily halve gross margin — knowing the real impact in advance lets you set discount limits that protect profitability. Use the percentage change calculator to verify exactly how large that discount is relative to your original price.
FAQ's
Margin is profit as a percentage of the selling price: (Revenue − Cost) / Revenue × 100. Markup is profit as a percentage of the cost: (Revenue − Cost) / Cost × 100. They use different denominators, so a 50% markup only produces a 33.3% margin — confusing them is one of the most common pricing mistakes.
It varies significantly by industry: Software/SaaS 70–90%; Retail 20–50%; Manufacturing 25–40%; Restaurants 60–70% on food cost (but high fixed overhead leaves thin net margins). Always compare to your industry benchmark rather than an absolute number.
Formula: Markup % = Margin % ÷ (1 − Margin %) × 100. For 40%: 0.40 ÷ 0.60 × 100 = 66.7% markup. Quick reference: 25% margin = 33.3% markup; 33.3% margin = 50% markup; 50% margin = 100% markup.
Formula: Selling Price = Cost ÷ (1 − Target Margin %). For a $100 cost with a 40% target margin: $100 ÷ 0.60 = $166.67. Select "Cost + Margin %" mode in this calculator — it does this automatically.
Contribution margin per unit = Selling Price − Variable Cost per Unit. It is the amount each unit sold contributes toward covering fixed costs. Once total contribution margin across all units sold equals total fixed costs, you have reached breakeven. Every additional unit sold beyond that point is profit.
Breakeven Units = Fixed Costs ÷ (Selling Price − Variable Cost per Unit). Breakeven Revenue = Breakeven Units × Selling Price. The contribution margin % = (Selling Price − Variable Cost) ÷ Selling Price × 100 — the breakeven tab shows all three figures simultaneously.
Gross margin subtracts only cost of goods sold (COGS) from revenue. Net margin subtracts all expenses: COGS, operating expenses (rent, salaries, marketing), interest, and taxes. Gross margin measures pricing and production efficiency; net margin measures overall business profitability. This calculator computes gross margin.
Select "Revenue + Margin %" when you know the selling price and your target margin, but want to find the maximum allowable cost. Formula: Cost = Revenue × (1 − Margin/100). For $150 revenue at a 33.3% margin: Max cost = $150 × 0.667 = $100. Useful for supply chain and procurement decisions.

Pricing is one of the highest-leverage decisions in any business — a 1% improvement in gross margin typically has a larger impact on profit than a 1% increase in sales volume. Toolaroid's free margin and markup calculator gives you instant, accurate numbers for any pricing scenario, plus a breakeven analysis to anchor every business decision in financial reality.
