Arc 1 • The Numbers That Run Your Business • Week 1 of 3
Gross Margin vs. Net Margin
A business can have a healthy gross margin and still lose money. The gap between the two is where the real story of your profitability lives.
Two businesses can report the same revenue and the same gross margin, and one can be thriving while the other is quietly going broke. The difference does not show up in either of those numbers. It shows up in the gap between gross margin and net margin — the space where rent, salaries, marketing, interest, and taxes all take their cut.
Monday's post covered break-even analysis: the revenue you need to cover your costs. Today is about what happens to each dollar after it comes in. Gross margin and net margin are two of the most important profitability metrics a Virginia small business owner can track, and understanding the relationship between them is what separates owners who react to their bank balance from owners who understand their business.
“A company can have a high gross margin but a low net margin if its operating, administrative, financing, or tax expenses are significant.”
Two Numbers, Two Different Questions
Gross margin and net margin answer fundamentally different questions about your business. Reading them together tells a story neither one tells alone.
Gross Margin
What is left after you subtract only the direct cost of delivering your product or service — the cost of goods sold. It answers: is my core offering priced correctly relative to what it costs to deliver?
Measures pricing & delivery efficiencyNet Margin
What is left after you subtract every expense — COGS plus rent, salaries, marketing, insurance, interest, depreciation, and taxes. It answers: is the business as a whole actually profitable?
Measures overall profitabilityBecause net margin subtracts every expense while gross margin subtracts only COGS, net margin is almost always the lower of the two. As Shopify notes, the only realistic exception is a rare one-time windfall, such as damages awarded in a lawsuit. In normal operations, net margin sits below gross margin — and the distance between them is the most revealing part of the picture.
Where the Money Goes: The Margin Ladder
The clearest way to see the relationship is to follow a single month of revenue down the income statement. Here is a simplified example for a Virginia service business with $100,000 in monthly revenue.
The business kept 65 cents of every revenue dollar after delivering its service — a strong gross margin. But by the time rent, salaries, marketing, interest, and taxes were paid, only 8 cents of each dollar remained as profit. That 57-point gap between gross and net is not a problem in itself. It is simply the story of where the money went. The question is whether each piece of that gap is justified.
Reading the Gap as a Diagnostic
The relationship between your two margins is one of the fastest diagnostics in small business finance. Britannica Money frames the three-tier view cleanly: gross margin shows whether the market lets you charge enough to cover the cost of what you sell; operating margin shows what is left after the costs of running the business; and net margin shows what remains for the owner after interest and taxes. Each tier narrows the picture.
Strong gross, weak net
Your pricing and delivery are efficient, but overhead is consuming the profit. The fix is on the operating expense side: rent, headcount, software subscriptions, marketing spend. This is the most common pattern for growing service businesses that added overhead faster than revenue.
Weak gross, any net
The problem is upstream, in your pricing or your direct delivery costs. Cutting overhead will not solve a gross margin problem. You need to raise prices, reduce direct costs, or change your service mix. Overhead discipline alone cannot rescue a business that is underpricing its core offering.
What Is a Good Margin? It Depends on Your Industry
There is no universal “good” margin. What is healthy for a software company would be catastrophic for a grocery store, and vice versa. The table below shows average margins by sector from the NYU Stern Damodaran dataset, one of the most widely cited margin datasets in finance, last updated January 2026. These reflect US public company averages — private and small business margins typically run somewhat lower — but they show the scale of variation across industries.
| Sector | Gross Margin | Net Margin |
|---|---|---|
| Software / Internet | 60%+ | Highly variable |
| Business & Consumer Services | ~33% | ~5% |
| Beverage (Soft) | ~55% | ~14% |
| Advertising | ~28% | ~1% |
The practical lesson is not to memorize any specific number. It is to benchmark against your own industry and, more importantly, against your own trend line. As AccountingTools notes, both margins are watched most closely as trends: a drop in either one relative to your own past performance is the signal worth investigating, regardless of how you compare to a national average.
A Virginia service business doing $1.5 million in revenue at a 3% net margin earns $45,000 — while an owner doing $180,000 at a 25% net margin earns the same, with far less complexity and risk. The revenue number alone tells you almost nothing about the health of the business. The margin tells you the truth.
You cannot calculate either margin accurately if your bookkeeping does not cleanly separate COGS from operating expenses.
The single most common bookkeeping issue we see in Virginia small businesses is direct costs and overhead lumped into the same categories, which makes gross margin impossible to calculate correctly. A chart of accounts that separates cost of goods sold from operating expenses at the category level means both margins can be read straight off your monthly financials. EveryCentCounts builds this separation into the bookkeeping we do for clients — so the story behind your profitability is always legible. Book a consultation to review your margin structure.
