How to Calculate Markup Percentage for Bookkeeping and Accounting

Markup percentage shows up in accounting and financial reporting slightly differently than in day-to-day pricing conversations — worth knowing so your internal pricing language matches what your books actually show.

The standard accounting calculation

(Sales revenue − Cost of goods sold) ÷ Cost of goods sold, expressed as a percentage — the same markup-on-cost formula used for pricing, just applied at the aggregate revenue level instead of per product.

Where this shows up in your financials

  • Gross profit on your income statement is the dollar version of this calculation, before operating expenses
  • Tracking markup percentage over time at the aggregate level flags pricing or cost drift before it shows up as a bigger problem in overall profitability

A reconciliation worth doing periodically

Compare your target per-product markup against your actual aggregate markup shown in the books — a meaningful gap between the two usually means discounting, returns, or cost creep is eating into margin somewhere that per-product pricing alone won’t reveal.
