Enter cost and revenue to calculate profit, profit margin, and markup. Results are educational estimates.
1. Enter cost (what you paid to produce or buy the item). 2. Enter revenue (selling price or sales total). 3. Click Calculate. 4. Read profit dollars, margin %, and markup % in the results. 5. Compare margin vs markup—25% markup is not the same as 25% margin.
Example: cost $60 and revenue $100 → $40 profit, 40% margin (40 ÷ 100), and 66.67% markup (40 ÷ 60).
Calculates gross profit (revenue minus cost), profit margin percent (profit ÷ revenue), and markup percent (profit ÷ cost). Useful for pricing reviews and P&L checks. Does not include operating expenses, taxes, or channel fees.

Profit = revenue − cost. Margin % = (profit ÷ revenue) × 100. Markup % = (profit ÷ cost) × 100.

Retailers often target a margin percent on selling price. Cost-plus pricing often starts with a markup on cost. Use Margin vs Markup Calculator to convert a target into a selling price.
