You look at your financial statements and see it: your gross margin is low. Maybe it’s been flat for months. Maybe it’s sliding. Either way, it’s a red flag. Gross margin tells you how efficiently you turn revenue into profit after direct costs. A low number means your core business model is leaking money. The good news? You can fix it. Here are the four most common causes and exactly what to do about each one.
Why Your Gross Margin Is Low: The Four Main Causes
Before you can fix low gross margin, you need to know why it’s low. Most businesses fall into one of these four buckets:
- Your prices are too low. You’re leaving money on the table. Your customers would pay more.
- Your cost of goods sold (COGS) is too high. Material costs, labor, or freight are eating your margin.
- Your product mix is dragging you down. You sell too many low-margin items and not enough high-margin ones.
- Your volume discounts or promotions have backfired. You’re selling more but making less per unit.
Each cause has a different fix. Let’s walk through them one by one.
Fix #1: Raise Your Prices (The Most Underused Lever)
Most business owners are shocked by how much they could raise prices without losing customers. If your gross margin is low, check your pricing first. A simple test: raise prices by 5% on a few products or services. Track the reaction. Often, demand stays the same, and margin jumps.
Value-Based Pricing vs. Cost-Plus Pricing
If you’re using cost-plus pricing, you’re probably pricing based on what you need, not what the market will bear. Switch to value-based pricing. Understand what your product is worth to your customer and price accordingly. A better price captures that value. For a deeper look at both approaches, see Value-Based vs Cost-Plus Pricing: Which Strategy Drives More Profit?
One common mistake: across-the-board discounts. If you offer a 10% discount to close a sale, you need roughly 11% more volume to make the same gross profit. Don’t assume volume covers the gap. Run the numbers first.
Fix #2: Cut Your Direct Costs Without Cutting Quality
The second lever is COGS. Start by auditing every line item. Raw materials, direct labor, packaging, shipping. Can you negotiate better rates with suppliers? Can you buy in bulk for a discount? Can you switch to a cheaper material that still meets specs?
Sometimes the biggest savings come from waste reduction. Track scrap rates, rework hours, and returns. Each defect costs you material and labor. Fixing a process that produces 5% scrap can boost margin by a full percentage point.
Also look at your fixed vs variable costs. Some costs you think are fixed might actually be variable and negotiable. If you can convert a fixed monthly fee to a per-unit cost, you lower your break-even point and improve margin.
Fix #3: Optimize Your Product Mix
Not all products are created equal. Some have 60% margin, others 20%. If your sales mix leans toward the low-margin items, your overall gross margin will be low. Calculate the margin for every product or service. Rank them from highest to lowest.
Then do two things: push sales toward high-margin items, and prune low-margin ones that don’t drive other sales. A simple table can help you decide.
| Product | Gross Margin % | % of Sales | Action |
|---|---|---|---|
| Premium Widget | 60% | 20% | Feature more, bundle upsells |
| Basic Widget | 30% | 50% | Raise price or cut costs |
| Loss Leader Widget | 5% | 10% | Eliminate or raise price drastically |
Use this table as a model. Plot your own products. You’ll often find that a small percentage of products generate most of your profit. Focus there.
Fix #4: Stop Leaking Margin with Poor Discounting
Discounts and promotions can be useful, but they destroy margin when used carelessly. Every time you offer a 20% discount, your gross profit on that sale drops by 20% (and sometimes more if the discount pushes you below your break-even point).
Calculate your break-even point for each product. Know the minimum price you can charge and still cover variable costs. Then set a floor. Never discount below that floor without a strategic reason, like moving obsolete inventory.
If you must offer discounts, use non-monetary incentives: free shipping, extended warranty, or bundling. Those affect margin less than a straight price cut.
When Gross Margin Is Low by Design
Sometimes a low gross margin is intentional. If you’re a retailer using a loss leader to get customers in the door, that’s a strategy. But you must track whether those customers buy high-margin items later. If they don’t, the low margin is a problem.
Similarly, if you’re in a hyper-competitive market with thin margins, you need to make it up on volume and efficiency. But even then, run the math. It’s often better to walk away from unprofitable sales than to stay busy for no profit.
How to Monitor and Sustain a Healthy Gross Margin
Once you’ve raised your gross margin, don’t slip back. Track it monthly. Set a target range and review any drop immediately. Build margin checks into your pricing approvals. Train your sales team on margin targets. And revisit your product mix quarterly.
A healthy gross margin gives you breathing room. It covers your overhead, funds growth, and rewards you for the risk you take. If yours is low, now you know exactly how to fix it. Start with pricing. Then costs. Then mix. Then discounts. Small changes in each area compound into real profit.
How to Prioritize Which Fix to Implement First
You may have multiple issues dragging down your gross margin. Deciding where to start can be the hardest part. Here’s a simple way to prioritize: rank each cause by how much it’s costing you and how easy it is to fix.
Start with pricing. It costs nothing to raise prices and the impact is immediate. If you raise prices by 5% and lose no volume, pure profit. That’s the lowest-hanging fruit. Even a small increase that sticks is a win.
Next, attack COGS. Supplier negotiations can yield quick wins if you have leverage. But if your contracts lock you in, focus on waste reduction first. That’s under your control and doesn’t require outside approval.
Product mix changes take longer because they involve shifting customer behavior. But the payoff is big: a 20% shift in mix from low to high margin can add several points to overall gross margin. Start by training your sales team to upsell and cross-sell high-margin items on every call.
Finally, review discounting policies. Set a margin floor and enforce it. Many businesses leak 2-3 margin points because sales reps give discounts without approval. A simple approval process can plug that leak overnight.
Common Mistakes When Fixing Gross Margin
Even with the right plan, entrepreneurs make avoidable errors. Here are three to watch out for.
First, cutting costs that hurt quality. If you switch to a cheaper material and your defect rate rises, your net margin might actually drop. Always test changes on a small batch before rolling out widely.
Second, raising prices across the board without testing. A 10% hike on your best-selling product could cause a big volume drop. Test on a subset of customers or a single product line first. Measure the reaction before committing.
Third, ignoring customer segmentation. Not all customers have the same price sensitivity. A 5% price increase may work fine for your loyal, repeat buyers but scare away new one-time shoppers. Consider tiered pricing: keep entry-level prices competitive and raise prices on premium tiers or add-ons.
Finally, watch your fixed costs. A common mistake is to cut variable costs so aggressively that you introduce new fixed costs (like expensive automation with a high monthly lease). That can increase your break-even point, making you more vulnerable if sales dip. Always consider the total cost structure, not just COGS in isolation.
Frequently asked questions
What is considered a low gross margin?
It depends on your industry. A low gross margin is generally below the average for your sector. For example, retail may average 30-50%, while software can exceed 70%. Compare your margin to industry benchmarks or your own historical performance. If it's consistently below what you need to cover operating expenses and still earn a profit, it's low.
Can raising prices hurt my sales more than it helps margin?
It can, if demand is very price-sensitive. That's why you test small increases first. Many businesses find that a 5% price increase has little to no impact on volume, but directly flows to profit. Track the effect on unit sales and total revenue before making larger changes.
How do I calculate my gross margin correctly?
Gross margin = (Revenue – Cost of Goods Sold) / Revenue, expressed as a percentage. Revenue is total sales. COGS includes only direct costs: materials, direct labor, and shipping. Do not include rent, marketing, or salaries for non-production staff. Use a consistent method so you can compare over time.
What if my competitors have the same low margins?
That's a red flag for the whole industry. Look for ways to differentiate your product or service so you can charge a premium. If you can't differentiate, focus on being the low-cost producer. Cut waste, automate, and negotiate better supplier deals to push your margin above the pack.
How often should I review my gross margin?
At least once a month. Review it formally as part of your financial close process. Track trends over 3, 6, and 12 months. If you see a sustained decline, investigate the cause immediately. The earlier you catch a margin leak, the easier it is to fix.
