Markup vs Margin

Markup and margin both describe the profit built into a price, but they calculate it from opposite directions — and confusing the two is one of the most common financial mistakes agencies make.

Markup is calculated on your cost. If something costs you $100 and you add a 50% markup, you charge $150. Margin is calculated on the selling price. If you charge $150 and your cost is $100, your margin is 33% ($50 profit ÷ $150 price). Same dollars of profit, very different percentages.

Here's where it gets agencies into trouble: a 20% markup is only a 16.7% margin. A 50% markup is a 33% margin. A 100% markup is a 50% margin. If your agency targets a 30% profit margin but your team is applying a 30% markup to costs, you're actually operating at about a 23% margin. At scale, that difference can mean hundreds of thousands of dollars in missing profit.

Getting markup and margin confused doesn't just create accounting headaches — it leads to underpricing. When your project managers quote jobs using a 25% markup thinking it gives them a 25% margin, every project is less profitable than expected. Over a year, across dozens of projects, this compounds into a significant revenue gap.

Pick one system and make sure everyone in your agency speaks the same language. Most agencies default to margin-based thinking because it's how profitability is measured in financial statements. But when communicating markups to clients (especially on pass-throughs), you'll talk in markup terms because that's clearer from their perspective.
