Gross profit margin is one of the most important numbers in any business. It tells you how much money you keep from each pound of revenue after paying the direct cost of delivering what you sell. Everything else — salaries, rent, marketing, software, taxes — comes out of that margin. If it's too thin, no amount of growth will save you.
This guide covers the gross margin formula, industry benchmarks, the critical difference between gross and net margin, and the specific levers you can pull to improve your gross margin starting this month.
The Gross Profit Margin Formula
There are two related calculations: gross profit (a pound figure) and gross profit margin (a percentage). You need both.
What counts as COGS? Direct costs only — the materials, direct labour, packaging, shipping, and processing fees tied directly to the product or service being sold. Rent, marketing, and your own salary are NOT included in COGS. They're operating expenses, and they come out of gross profit.
What Is a Good Gross Profit Margin? By Industry
There is no universal answer — 30% can be excellent in one industry and catastrophic in another. Here are the benchmarks that matter.
| Industry | Typical Gross Margin | Why |
|---|---|---|
| SaaS / Software | 70–85% | Near-zero COGS per user; hosting costs scale slowly |
| Consulting / Services | 60–75% | COGS = direct labour only; no materials |
| Digital Products | 80–95% | COGS are near zero after creation |
| E-commerce (branded) | 40–60% | Product cost + fulfilment + returns |
| E-commerce (reseller) | 20–40% | Thin margins; buying vs selling price gap |
| Food & Beverage | 60–70% | Ingredient cost ~30-40% of sale price |
| Restaurant / Hospitality | 30–40% | High ingredient and portion cost |
| Manufacturing | 25–45% | Dependent on automation and volume |
| Construction / Trades | 20–35% | Materials + subcontractor costs are high |
| Retail (physical) | 30–50% | Wholesale-to-retail markup vs occupancy |
The higher the gross margin, the more room you have for mistakes, growth investment, and actual profit. SaaS companies can survive a lot of growth-phase losses because their margin is so high. A restaurant at 30% gross margin has almost no room for anything to go wrong.

These two numbers tell completely different stories about a business. Confusing them is one of the most common financial mistakes founders make.
The same business has a 65% gross margin and a 16.5% net margin. Gross margin tells you how efficient the core product is. Net margin tells you if the whole business is profitable.
A business can have a high gross margin and still be unprofitable if overheads are too high. Conversely, a low gross margin business (like a trade contractor) can be very profitable if fixed costs are lean.
Gross margin is a product problem. Net margin is a business model problem. Fix gross margin first — there's no point cutting overheads if your unit economics are broken.
6 Levers to Improve Your Gross Profit Margin
Gross margin can be improved from either side of the equation: cut COGS, or increase revenue without proportionally increasing COGS. Here are the six most effective levers.
The highest-impact, lowest-effort lever for most businesses. A 10% price increase on a 50% margin product moves gross margin to 55% with no change in volume. Most founders undercharge. The evidence: if nobody ever pushes back on your price, you're priced too low.
If you have volume, use it. Ask for volume discounts, extended payment terms, and annual contracts in exchange for commitment. Even a 5% reduction in materials cost can add 3-4 margin points to a product business running at 40% gross margin.
In manufacturing and food businesses, waste is a direct tax on gross margin. Track yield rates per production run. If 8% of materials are wasted per batch, fixing that is pure margin — no revenue change required.
Not all products or services carry the same margin. Identify your top-margin offerings and actively promote them more. A cleaning company may make 60% on specialist treatments but only 30% on standard cleans — steering customers toward specialist work improves overall margin without a price increase.
Direct labour in COGS is often the biggest cost to attack. Any recurring, rule-based task in your delivery process is a candidate for automation. Even partial automation — reducing a 2-hour task to 45 minutes — directly improves gross margin.
The Pareto principle applies to margin: ~20% of products or customers often generate 80%+ of gross profit. Eliminating or repricing the bottom 20% of margin-destroyers can increase overall gross margin dramatically — and free up capacity for higher-margin work.
Frequently Asked Questions
What is a good gross profit margin for a small business?
It depends heavily on the industry. For service businesses and SaaS, 60-80% is good. For e-commerce, 40-60% is reasonable. For physical retail or manufacturing, 30-50% is typical. The key question is whether your gross margin leaves enough room, after overheads, for meaningful net profit.
Is gross margin the same as markup?
No. Markup is calculated on cost. Margin is calculated on revenue. A 100% markup (doubling your cost) gives you a 50% gross margin. A 67% markup gives you 40% margin. Always use margin for business analysis — markup can be misleading when comparing across different cost bases.
Can gross margin be negative?
Yes, and it means you're losing money on every sale before overheads. This is only sustainable temporarily during a startup phase with a clear path to positive gross margin at scale. If your gross margin is negative and it isn't intentional and time-limited, you have a business model problem, not a growth problem.
Why is my gross margin lower than competitors in the same industry?
Common causes: higher supplier costs (smaller volumes, fewer negotiations), more waste or inefficiency in delivery, lower prices than the market (possibly a positioning problem), or a different product mix. Audit your COGS line by line against your best-performing competitor's public financials if they're available.
