Is your business making sales but still not seeing real profit? You’re not alone. Many business owners get confused when revenue is coming in, but the numbers still don’t look right. This is where a negative gross profit margin shows up.
In our 6+ years providing bookkeeping services for US small businesses, we often see steady sales but no real profit at the end of the month.
In simple terms, a negative gross prof./it margin means your costs are higher than your sales. You’re spending more to produce or deliver a product than what you’re earning from it. That’s why even steady sales don’t always lead to profit.
This situation is also closely linked to negative profit margin and low profit margin, where businesses find it hard to cover basic expenses. If it’s left unchecked, then it can lead to cash flow problems, poor pricing decisions, and long-term survival issues.
What is a negative gross profit margin?
A negative gross profit margin (sometimes called a negative gross margin) occurs when your cost of goods sold (COGS) is higher than your revenue. In simple terms, you’re spending more to deliver a product or service than what you’re earning from it.
Gross profit margin formula
The gross profit margin is calculated using a simple formula:
Gross Profit Margin = (Total Revenue – Cost of Goods Sold) ÷ Total Revenue × 100%
Gross profit = Revenue − Cost of goods sold (COGS). Gross profit margin is the percentage of profit left after those costs.
The Internal Revenue Service requires accurate reporting of gross receipts and cost of goods sold on Schedule C, since COGS directly reduces the taxable income a business reports each year.
Example of a gross profit margin:
Revenue = $10,000, Cost of Goods Sold (COGS) = $12,000
Gross Profit = 10,000 – 12,000 = -2,000
Gross Profit Margin = (-2,000 ÷ 10,000) × 100 = -20%
This means your business is operating at a negative gross margin. On average, it’s costing you more to deliver your sales than you’re earning from them.
- Positive margin means you are making a profit
- Zero margin means you are just covering costs
- Negative margin means you are losing money
You don’t need fancy tools to start. A simple spreadsheet will show you your gross margin in minutes.
Can gross profit or gross margin be negative?
Yes. If your cost of goods sold is higher than the revenue you’re bringing in from those sales, your gross profit becomes negative. It’s not common for an established business, but it happens more often than owners expect, especially with underpricing or rising supplier costs.
Can profit be negative? Yes, and it’s a related but separate warning sign. Net profit can be negative even when gross profit is positive, if expenses like rent, payroll, and marketing use up the remaining profit. A negative gross profit is a bigger concern because it means your sales, on average, aren’t covering the product or service itself before you even get to operating costs.
What does a negative gross profit margin mean?
A negative gross margin doesn’t just reduce profit. It usually means the business model isn’t working at the most basic level, and in that situation, selling more will only deepen the loss.
When your gross margin ratio is negative, it means your core operations are not profitable. Even before paying rent, salaries, or marketing costs, you’re already in the loss.
Growth doesn't fix it and selling more at a negative average margin increases the total loss.
Cash flow becomes unstable. A low profit margin or negative margin makes it hard to manage daily expenses.
It's hard to scale the business. Growing a business that loses money at the product level just grows the loss.
Investors and lenders lose confidence. A negative profit margin signals risk and poor financial health.
Long-term sustainability is at risk if it isn't fixed.
Can a business have a negative gross profit margin?
Yes, it usually happens because of low pricing, heavy discounts, higher supplier costs, poor pricing strategies, or inefficient operations.
In many cases, businesses don’t even realize they have a negative gross margin until they review their numbers properly.
What causes a negative gross profit margin?
A few causes of negative gross profit margin are:
High Cost of Goods Sold (COGS)
This is one of the biggest reasons. If your production, material, or service delivery costs are too high, your profit gets low. Even small cost increases can turn your gross profit percentage negative.
Underpricing Your Products or Services
Many businesses set prices too low to attract customers. But if your pricing doesn’t cover your costs, then it results in a negative profit margin. Selling more in this case only increases your losses.
Heavy Discounts and Offers
Frequent discounts may increase sales, but they can damage your margins. If you’re constantly reducing prices, your gross margin ratio will decrease, sometimes even becoming negative.
Poor Cost Control
Unmanaged expenses like wastage, overproduction, or inefficient processes can increase your costs without you noticing. This directly affects your gross profit rate, which is one reason regular bank reconciliation matters even when sales look steady.
Higher supplier costs
If you’re paying too much for raw materials or inventory, your margins will suffer. Many businesses don’t negotiate with suppliers, which leads to higher costs and negative margins, meaning ongoing losses.
Inefficient Operations
Slow production, poor workflow, or outdated systems can increase time and cost per unit. This reduces your overall gross profit ratio.
Unexpected cost increases
Sometimes the cause isn't anything you did. Rising supplier costs, inflation increasing material and labor expenses, or a sudden drop in customer demand can turn a healthy margin negative almost overnight. You can't always control these changes, but regularly monitoring your numbers can help you spot problems early and adjust your pricing before they start hurting your profitability.
Why is my gross margin so low in a service business?
Gross margin becomes low due to these reasons:
High labor costs
A low or negative gross margin in a service business usually comes from different issues than in a product-based business. Instead of materials or inventory, your biggest cost of goods sold is often the time and labor required to deliver the work.
Scope creep and unbilled work
This can happen when extra work is completed without billing for it. The margin may seem fine at the start, but it erodes as unbilled hours pile up.
Underpriced fixed-fee projects
A fixed-fee project that takes far more time than expected can end up generating little profit, or even a loss, once the work is actually finished.
Poor job-level cost tracking
It’s important to track the cost and profitability of each project, not just your total revenue. One underpriced client or project can reduce your overall gross margin, even when the rest of the business is performing well.
Warning signs your gross margin is turning negative
A negative gross margin usually doesn’t show up all at once. Sales may still be coming in and everything can seem fine on the surface while the problem develops quietly as costs rise faster than revenue.
Here are some common warning signs:
- Sales are growing, but cash keeps getting tighter. You may be selling more of something that isn’t generating enough profit to cover its own costs.
- Your costs have increased, but your prices haven’t moved in a year.
- Your gross margin keeps getting smaller month after month, not just a one-time drop.
- You’re relying on discounts as your main way to get new customers.
- You don’t know which products or services are actually profitable.
If two or three of these feel familiar, it’s worth taking a closer look at your numbers. The sooner you spot a margin problem, the easier and less expensive it is to fix.
Business growing but margins getting worse? Here’s why
Growth can increase revenue, but it can also expose margin problems. A few common reasons:
- Rush costs: More orders can mean rush shipping, overtime, or expedited materials. Those extra costs quickly eat into your margins.
- Discount-driven growth: Sales may be increasing because of discounts, but if you're selling at lower prices, your margin on each sale gets smaller.
- Hiring ahead of revenue: Hiring staff before the extra revenue arrives adds costs immediately, while it may take months for sales to catch up.
- Stale supplier pricing: Rates negotiated when the business was smaller often go unreviewed as volume increases, so you may end up paying more than necessary.
None of this means growth is bad. It means you need to check your margins as the business grows instead of waiting until year-end to spot the problem.
Negative gross profit vs negative net profit
Gross profit margin looks at your profit after direct costs, and net profit margin shows what’s left after all expenses. Many people mix these two up, but they show very different things.
| Metric | What it includes | What it shows |
|---|---|---|
| Gross profit margin | Revenue - COGS | Profit from core operations |
| Net profit margin | All expenses (rent, salaries, taxes) | Final profit |
Example: Revenue = $10,000, COGS = $6,000, so Gross profit = $4,000. Other expenses = $5,000. Gross profit margin is positive, but net profit becomes negative. This means the product is profitable, but the overall business is not.
Negative gross profit
A negative gross margin means you’re losing money on the product or service itself, before any other cost is even counted.
Negative operating profit
Operating margin goes further and subtracts running costs like rent and salaries. Your operating margin can be negative even when gross margin is positive. It means day-to-day operations are losing money.
Negative net profit
Net margin includes taxes, interest, all expenses. If net margin is negative, the business lost money overall for that period, even if the product line itself is profitable.
What is a good gross profit margin?
A good gross profit percentage depends on your industry, but there are general numbers you can follow. A good gross profit margin for a software company would be terrible for a grocery store. So don’t compare yourself to the wrong benchmark.
Here’s where real businesses actually land, based on industry margin data compiled by NYU Stern (Damodaran Margins by Sector, US public companies, data as of January 2026):
| Industry | Typical Gross Margin |
|---|---|
| Software/ SaaS | ~70% |
| Healthcare products | ~54% |
| Apparel | ~57% |
| Restaurants/Dining | ~32% |
| General retail | ~33% |
| Construction/engineering | ~15% |
| Auto dealers | ~22% |
| Total market average | ~38% |
These are averages for large public companies. Most small businesses run a bit lower than these, so don’t worry if your number isn’t as high as these.
- A higher gross margin ratio means more room to cover rent, payroll, and marketing.
- A lower one isn’t always bad; grocery and auto run on thin margins but high volume.
- Anything negative means you’re losing money before you even pay the bills.
Compare your own gross profit percentage against your own industry. That’s the only number that tells you the truth.
Your operating margin comes after you subtract running costs like rent and salaries. A good operating margin for most small businesses sits in the 10-15% range. Gross margin shows if your product makes money, and operating margin shows if your whole business does.
How to fix a negative gross profit margin
If you’re dealing with a negative gross profit margin or even a low profit margin, you can fix it. Practical steps are:
1. Review your pricing
- Increase prices carefully.
- Make sure your price covers your costs and gives a profit.
- Test small changes instead of big ones.
2. Reduce Cost of Goods Sold (COGS)
- Find cheaper suppliers.
- Buy in bulk for discounts.
- Reduce material waste.
3. Negotiate supplier costs
- Ask for better rates.
- Find alternative vendors.
- Build long-term supplier relationships.
4. Reduce unprofitable discounts
- Use discounts strategically instead of constantly.
- Focus on value instead of cheap pricing.
5. Improve operational efficiency
- Simplify operations and reduce production time.
- Use better systems or tools.
6. Focus on profitable products, services, and jobs
- Identify products with a better gross profit percentage and promote or scale those.
- Reduce focus on low-margin items.
Look at each job on its own, not just your business overall. In construction and service work, one project can quietly lose money even when the rest are fine. So, check the gross margin job by job because that’s usually where the problem is hiding.

FAQs
Can net profit be negative when gross profit is positive?
Yes, this can happen when a business makes money from its products or services, but other expenses like rent, salaries, and marketing cost more than that profit. So, the product itself is profitable, but the business as a whole is still losing money.
How do you fix a negative profit margin?
You can fix a negative gross margin by increasing prices, reducing costs, improving efficiency, and focusing on high-margin products.
What does a negative gross margin mean?
It means your direct costs are higher than your revenue, so you're losing money on the product or service itself, before any rent, payroll, or other expenses.
Can a service business have a negative gross margin?
Yes. This can happen when a project is priced too low, extra work isn’t billed, or a fixed-price job takes much longer than expected. Because labor is the main cost in a service business, one underpriced client can make the whole margin negative even if other projects are profitable.
Can operating margin be negative?
Yes, a negative operating margin means your day-to-day running costs (rent, salaries, overhead) are higher than your gross profit, so operations are losing money even if individual products sell at a profit.
