What is Profit Margin Calculator?
How It Works
Choose a calculation mode and enter two values โ the calculator computes the rest. In Cost & Revenue mode, enter your cost and selling price to see profit, margin %, and markup %. In Cost & Margin mode, enter your cost and target margin to find the selling price needed. In Cost & Markup mode, enter cost and markup percentage to find the selling price and equivalent margin. All formulas are shown in the results.
Formula
Profit = Revenue โ Cost Margin (%) = (Profit / Revenue) ร 100 Markup (%) = (Profit / Cost) ร 100 Revenue from margin: Revenue = Cost / (1 โ Margin/100) Revenue from markup: Revenue = Cost ร (1 + Markup/100)
Formula Explained
Margin and markup measure the same profit from different perspectives. Margin asks "what fraction of the selling price is profit?" while markup asks "how much did I add to the cost?" Converting between them: Margin = Markup / (1 + Markup/100) ร 100. For example, a 100% markup gives a 50% margin because the profit equals the cost, but is only half the selling price.
Example
Cost: $20.00, Revenue: $25.00 Profit: $5.00 Margin: ($5 / $25) ร 100 = 20.00% Markup: ($5 / $20) ร 100 = 25.00% To achieve a 30% margin on a $20 cost: Revenue = $20 / (1 โ 0.30) = $28.57 Profit = $8.57, Markup = 42.86%
Tips & Best Practices
- โKnow your break-even point โ the sales volume where total revenue equals total costs.
- โTrack both gross margin (before overhead) and net margin (after all expenses).
- โA 50% markup is NOT the same as a 50% margin โ it is only a 33.3% margin.
- โWhen negotiating discounts, calculate the margin impact, not just the percentage off.
