Gross Profit
Revenue minus direct cost of goods sold. Measures how profitable the product or service is before overhead.
Definition
Gross profit is revenue minus COGS (direct cost of goods sold). It tells the whole story of the underlying business model: is the thing you sell actually profitable on its own? A business at 20% gross margin needs huge volume to cover overhead, while a 70% margin business can fund team, marketing and infrastructure from the product itself. Compare gross margin within an industry, not across industries. Retail and grocery run 20-30%, professional services 50-80%, SaaS typically 70-90%. A trending-down gross margin signals a problem: rising input costs, price pressure, or worsening product mix. Improving gross margin is usually the single biggest lever on overall profitability.
How to calculate gross profit correctly
Gross profit equals revenue minus cost of goods sold (COGS). For a US LLC or S-Corp selling services, COGS includes direct labor on billable work, subcontractor fees, software licenses tied directly to delivery (e.g., a per-seat tool used only on client accounts), and merchant processing fees on the revenue itself. Exclude founder salary that is not delivery-related, office rent, marketing spend, accounting fees, and general SaaS tools. The biggest mistake US founders make is parking everything under operating expenses to make gross margin look glamorous, then panicking when net profit collapses. A clean P&L in QuickBooks or Xero with a real COGS section tells the truth: are you actually selling a profitable thing, or just selling a lot of an unprofitable thing?
Industry benchmarks in the US market
Gross margin benchmarks vary by sector. US professional services (consulting, agencies, accounting) typically run 50 to 70 percent gross margin once fully loaded labor cost is in COGS. SaaS at scale lands 75 to 85 percent. E-commerce on Shopify with paid acquisition runs 30 to 50 percent. Construction and trades sit at 20 to 35 percent. Restaurants run 60 to 70 percent food margin but very low net margin. Compare yourself to your sector inside US peer benchmarks (BizMiner, IBISWorld, RMA Annual Statement Studies) not to public companies, which carry economies of scale you cannot replicate. If you are 10 points below your peer median, the fix is almost always pricing, not cost cutting.
Levers that move gross margin
Three reliable levers, in order of return: pricing, mix, and delivery efficiency. Pricing is the strongest because every extra dollar lands at 100 percent gross margin. Most service founders are underpriced by 15 to 30 percent and do not realize it until they raise rates on new clients and nothing breaks. Mix means shifting revenue toward higher-margin services and away from low-margin work you only kept out of loyalty. Delivery efficiency means productizing recurring tasks, using AI for first drafts, and standardizing scope so you stop burning unbillable hours. Cost cutting in COGS (cheaper subcontractors, lower-tier tools) almost always hurts quality and shows up in churn within two quarters.
When gross profit lies
Gross profit can look healthy while the business is dying. Three traps. First, revenue recognition: if you book a 12-month annual contract as revenue on day one but only pay COGS as the work happens, early months look great and later months look terrible. Use ASC 606 style recognition to match. Second, unbilled write-offs: hours your team spent that you ate as scope creep are real COGS, even if not invoiced. Track them. Third, founder labor at zero cost. If you do 30 hours per week of delivery and pay yourself nothing, gross margin is inflated. Assign a market salary to your delivery hours before judging margin.
FAQ
Is gross profit the same as gross margin?
No. Gross profit is a dollar amount: revenue minus COGS. Gross margin is the same thing expressed as a percentage of revenue. A business with 500K revenue and 200K COGS has 300K gross profit and a 60 percent gross margin. Investors and operators usually compare margins because dollars hide scale differences. Always state both when reviewing a P&L with a partner or accountant.
Should I include payment processor fees (Stripe, PayPal) in COGS?
Yes. Stripe, PayPal, and Square fees are direct costs of generating revenue. They scale linearly with sales and disappear if the sale disappears, which is the definition of COGS. Most QuickBooks and Xero default charts of accounts park processing fees under operating expenses, which inflates gross margin. Move them. On a 2.9 percent plus 30 cent transaction fee, a 1M revenue business hides about 30K of true COGS if these are mis-categorized.
Why is my gross margin dropping even though prices have not changed?
Three usual suspects. One, input costs rose (subcontractor rate hikes, SaaS price increases, payroll cost-of-living adjustments) and you absorbed them. Two, mix shifted toward lower-margin services without you noticing - run a margin report per service line monthly. Three, scope creep on existing clients is eating delivery hours that are not getting billed. The fastest diagnostic is to compare current month gross margin per service line versus the same month last year.
How often should I review gross margin?
Monthly at minimum, ideally weekly during a turnaround. Set up a simple dashboard in Google Sheets or a BI tool that pulls from QuickBooks or Xero showing trailing 12-week gross margin, broken down by service line and by client. Below 90 days of data, monthly review is enough. Below 6 months runway, weekly review is mandatory because gross margin is the highest-leverage metric you can move quickly.
Does the IRS care about how I categorize gross profit?
The IRS cares about your gross profit calculation on Schedule C (sole proprietor) or Form 1120 (corporation) because COGS is deductible above the line and can affect estimated tax. The IRS does not enforce a strict definition of what belongs in COGS versus operating expenses for service businesses, but you must be consistent year over year. Switching categorization between years to manage tax exposure is a red flag in an audit. Talk to a CPA before reclassifying line items.
