Quick Answer & Key Takeaway (TL;DR)

Profit percentage can be calculated either as Profit Margin (Profit ÷ Revenue × 100) or as Markup on Cost (Profit ÷ Cost × 100). For example, buying a product for $60 and selling it for $100 yields a $40 profit, representing a 40.0% profit margin and a 66.7% markup on cost.

Whether operating an e-commerce storefront, manufacturing physical goods, or consulting for clients, an accurate profit percentage calculator is essential for sustainable business profitability.

Profit Margin vs. Markup Formulas

Comparative breakdown: Why a $50 profit yields a 50% markup on cost but a 33.3% profit margin on revenue.
Profit Margin Equation
Margin (%) = [(Revenue - Cost of Goods Sold) ÷ Revenue] × 100
Markup Equation
Markup (%) = [(Selling Price - Cost) ÷ Cost] × 100

How to Price Products for a Target Margin

To achieve a target gross margin percentage $M$, use the pricing formula: Price = Cost ÷ (1 - M). If your cost is $50 and you desire a 30% margin: $50 ÷ 0.70 = $71.43.

Frequently Asked Questions

What is the formula for profit percentage (profit margin)?
Profit Margin (%) = ((Selling Price - Cost) ÷ Selling Price) × 100.
How do you price an item to achieve a 40% margin if it costs $60?
Price = Cost ÷ (1 - Margin) = $60 ÷ (1 - 0.40) = $60 ÷ 0.60 = $100. (Do not multiply $60 by 1.40, which only gives a 28.5% margin!).
