Retail & E-Commerce Pricing: Margin vs. Markup Explained

The confusion between margin and markup is one of the most common and costly financial mistakes in business pricing.

The Critical Difference

  • Gross Margin (%): The percentage of the final selling price that is pure profit). Margin can never exceed 100%.
  • Markup (%): The percentage added onto the original cost to arrive at the selling price). Markup can exceed 100% (e.g., a 100% markup on a 50 item is a 100 price, which is a 50% margin!).

Quick Margin-to-Markup Conversion Table

  • 20% Margin = 25.0% Markup
  • 33.3% Margin = 50.0% Markup
  • 50% Margin = 100.0% Markup (Keystone pricing)
  • 75% Margin = 300.0% Markup

Worked Example

For example, purchasing an item for a COGS of 60.00 and selling it for 100.00: . The Gross Margin is . The Markup is . Selling 1,000 units per month generates 100,000.00 in revenue and 40,000.00 in monthly gross profit.

Understanding Your Result

Gross margin and markup are different: 50% markup = 33% gross margin. Pricing strategy varies by industry: SaaS software targets 70–85% gross margins; e-commerce typically 30–50%; professional services 50–70%; retail 25–50%; restaurants 60–75% (gross food cost margin). A gross margin below your industry average signals pricing pressure or high COGS — investigate before scaling. Contribution margin (revenue minus variable costs only) is the more useful metric for short-term pricing and production decisions.

❓ Frequently Asked Questions

What is the difference between profit margin and markup?

Margin is profit divided by revenue (selling price), while markup is profit divided by cost (COGS). For example, buying an item for $50 and selling for $100 yields a 100% markup and a 50% margin.

What is a good gross profit margin for a small business?

A healthy gross profit margin typically ranges between 40% and 60% for retail and e-commerce, 50% to 70% for services, and 75% to 85%+ for software (SaaS).

How do you calculate selling price from a desired profit margin?

Divide the unit cost (COGS) by (1 minus the decimal margin): Selling Price = Cost / (1 - Margin). For a $60 cost and 40% target margin, Price = $60 / 0.60 = $100.

What is Keystone pricing in retail?

Keystone pricing is a retail pricing rule of thumb where merchandise is priced at exactly double the wholesale cost (a 100% markup, resulting in a 50% gross margin).

Why is COGS important in gross margin calculation?

Cost of Goods Sold (COGS) includes all direct expenses required to produce or acquire a product (raw materials, manufacturing labor, packaging, freight shipping). Subtracting COGS from revenue gives the gross profit available to cover overhead and marketing.
