What Is Markup?

The three numbers sit in one simple relationship: bill rate equals pay rate plus markup. A client negotiating on bill rate alone is really negotiating on markup, since pay rate is largely fixed by what it takes to keep the worker on assignment. Markup expressed as a percentage of pay rate and markup expressed as a percentage of bill rate (margin) describe the same dollar spread against two different base numbers, which is the single most common source of confusion when an agency compares its own rate quote against a competitor's.

Every currently-ranking article on this exact topic, including pieces from altLINE, HCMWorks, and Rely Workforce, walks through the bill rate, pay rate, and markup relationship as a static, hand-calculated explainer. None of them is an interactive tool: a prospect or a new agent still has to do the arithmetic themselves, row by row, for every candidate and every client scenario.

Markup is not pure profit. Burden costs, the employer-side payroll taxes, workers' comp premiums, and benefits an agency carries on every W-2 placement, come out of markup before what is left counts as real margin, which is why two agencies quoting the same headline markup percentage can be running very different actual profitability depending on their burden rate.
