Profit margin is the percentage of revenue that remains as profit after costs are deducted. Formula: Margin (%) = ((Revenue - Cost) / Revenue) * 100. Markup, on the other hand, is the percentage added to the cost to reach the sales price. Formula: Markup (%) = ((Revenue - Cost) / Cost) * 100.
Find the sweet spot between cost and profit.
Formula:
Margin = (Revenue - Cost) / RevenueBuy for $50, Sell for $100.
Result: 50% Margin. 100% Markup.
Cost $80, Sell $100.
Result: 20% Margin. 25% Markup.
Margin is calculated based on Revenue, while Markup is based on Cost. Margin is used for bottom-line analysis; Markup is used for setting prices.
It varies by industry, but typical ecommerce gross margins range from 30% to 50%.
If you want a 40% margin on a $50 cost, use: Price = Cost / (1 - 0.4). So $50 / 0.6 = $83.33.
Margin is the most critical metric for assessing business health and sustainability. A "High Margin" business (50%+) typically has lower sales volume but high per-unit profitability. Common pricing error: confusing 50% markup (cost + 50%) with 50% margin (cost * 2). Net Profit Margin also accounts for operating expenses, taxes, and interest, unlike Gross Margin.
The Margin Curve (Y-axis) increases at a diminishing rate as Sale Price (X-axis) rises. To double your margin from 10% to 20%, you need a larger price hike than moving from 50% to 60%, assuming fixed costs.
