Gross margin is the percentage of revenue remaining after subtracting the direct cost of goods sold. It shows pricing power and production efficiency. A 60% gross margin means you keep $0.60 of every $1 earned after direct costs, before overhead and taxes.
Gross margin reveals the core strength of your business model - can you actually make money on the product or service you're selling? It's independent of how you manage overhead or finance yourself. Two businesses with identical gross margins might have completely different net profits because one has lower overhead, but the gross margin tells you who has the fundamental pricing and cost advantage.
For small business owners, gross margin is the number that drives pricing decisions. If you cut prices to win market share and gross margin drops below what's sustainable, you need to cut production costs or you'll erode profitability no matter how much revenue you drive. Many small business owners cut prices too aggressively and end up with high revenue but negative profit.
For accountants, gross margin is the first thing to analyze when a client's profit is declining. Is the problem the core business (gross margin shrinking), or is it overhead bloat (gross margin fine, but operating expenses growing)? These require different fixes. Accountants also use gross margin to forecast: if next year's revenue grows 20% but gross margin is stable, gross profit grows 20%. If gross margin is declining, net profit can grow slower or even decline despite revenue growth.
Gross margin isolates the cost of producing your product or service, separate from everything else.
The calculation:
Gross Profit = Revenue - Cost of Goods Sold (COGS) Gross Margin (%) = Gross Profit / Revenue x 100
What counts as COGS:
Only direct costs to produce the product or service. Examples:
What does NOT count as COGS:
Real example - product business:
A craft jewelry maker hand-makes necklaces and sells them online:
The maker keeps $0.80 of every $1. But this doesn't account for website hosting ($20/month), marketing ($500/month), or the maker's own time managing the business. Net profit is much lower.
Real example - service business:
A freelance tax accountant:
The accountant keeps $0.88 of each dollar of revenue, before their own salary, marketing, administrative costs.
Common variation - mix and match:
Businesses with both products and services sometimes calculate separate gross margins for each. A tax firm offering software + consulting might have:
This helps identify which part of the business is more profitable and where to invest.

Best practices:
Gross margin is the percentage of each sale that's left over after you pay the direct cost to produce it. If you sell a product for $100 and it costs $40 to make, your gross profit is $60, and your gross margin is 60%. It shows how efficiently you convert sales into profit before overhead and taxes. Higher margin = more breathing room to cover salaries, rent, and taxes.
Gross Margin = (Revenue - Cost of Goods Sold) / Revenue x 100. Example: If you earned $50,000 and your COGS was $15,000, your gross profit is $35,000. Gross margin = $35,000 / $50,000 x 100 = 70%. Every dollar of revenue, you keep $0.70 after direct production costs.
Gross margin is the first profitability metric. It tells you whether your core business model is sound - whether you're charging enough relative to production costs. A declining gross margin is a red flag even if revenue is growing: either you're facing pricing pressure (competitors cutting prices) or production costs are rising (inefficiency, inflation, supply chain). Accountants track it monthly to spot these trends early.
Gross margin excludes overhead (salary, rent, marketing, utilities); net profit margin includes everything. A business can have a strong 70% gross margin but a weak 5% net profit margin if overhead is high. Gross margin shows production efficiency; net margin shows overall profitability. Most accountants look at gross first (can we make money on the product?), then net (can we run the business profitably?).
It depends on industry. Software products often run 70-90% gross margins (low production cost). Manufacturing might be 30-40%. Service businesses (consulting, accounting) often 50-80% depending on labor efficiency. The key is trend: if gross margin is growing, you're gaining pricing power or reducing costs. If it's shrinking, pricing is under pressure or costs are rising. Compare yourself to industry benchmarks, not absolutes.
Because overhead (salaries, rent, marketing, utilities) comes after gross margin. A SaaS company might have 85% gross margin but 8% net margin because it spends 45% of revenue on sales and marketing, and 32% on engineering and operations. High gross margin is necessary but not sufficient for profitability - you also need controlled overhead.
The total income your business earns from selling products or services, before any costs are deducted. It's the top line of your income statement and the starting point for calculating profit.
Net profit is the money remaining after subtracting all expenses, taxes, and costs from total revenue. Also called the 'bottom line,' it's the definitive measure of whether your business is actually making money.
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures your operating profit by stripping out financing costs, tax effects, and non-cash expenses. It shows what your business actually earned from core operations.
