Gross margin is the percentage of revenue remaining after deducting the cost of goods sold (COGS). Expressed as a percentage, it measures how efficiently a company converts revenue into profit before accounting for operating expenses, and is a critical metric for pricing strategy and business model viability.
Formula
Gross Margin = (Revenue - COGS) / Revenue x 100In Depth
Gross margin is one of the first metrics investors, analysts, and FP&A teams examine when assessing a business. It reveals how much of each pound of revenue is available to cover operating expenses and generate profit, making it a fundamental indicator of business model health.
The formula is straightforward: Gross Margin = (Revenue - COGS) / Revenue x 100. A company with £1M in revenue and £400K in COGS has a 60% gross margin, meaning 60p of every pound earned is available for operating costs, investment, and profit.
Gross margins vary enormously by industry and business model. UK SaaS companies typically achieve 70-85% gross margins. Professional services firms operate at 30-50%. Retail businesses range from 25-60% depending on the category. Manufacturing margins can be anywhere from 15-45%. Understanding industry benchmarks is essential for FP&A teams setting targets and assessing performance.
Trend analysis is key. A declining gross margin might signal rising input costs, competitive pricing pressure, or a shift in product mix towards lower-margin offerings. An improving gross margin could reflect economies of scale, successful price increases, or operational efficiencies.
FP&A teams should model gross margin at multiple levels — by product line, customer segment, and geography — to understand where value is created and where it is eroded. This granularity enables more informed pricing, product development, and go-to-market decisions.
For UK businesses, gross margin analysis should consider the impact of sterling fluctuations on imported input costs, seasonal variations in pricing power, and the effect of volume discounts on overall margin.
Real-World Example
A UK SaaS company reports 78% gross margin on its core product but only 45% on its managed services offering. The blended gross margin is 71%. The FP&A team models that shifting the revenue mix from 80/20 to 70/30 (more services) would compress the blended margin to 68%, reducing the operating leverage that investors value. This analysis informs the decision to invest in product features that reduce the need for managed services.
