What Amazon Profit Margin Should You Actually Have? The 30% Floor

The short version

• The number that decides everything is your pre-ad gross margin: what one unit keeps after true landed COGS and Amazon's fees, before a dollar goes to advertising.
• For consumables, 30% is the floor. Durable goods need more, closer to 40% at the bottom and 50% to scale comfortably. Under 20% is the red zone and we decline that work.
• Margin sets your marketing budget, not the other way around. It tells you what you can afford to spend on ads, on an agency, and on discounts, before you commit to any of them.
• Having headroom is not a reason to use it. Margin you don't spend is promotional flexibility for Prime Day, Black Friday and the month you go out of stock.
• Build it per SKU. A blended catalog average hides the loser inside the winner, and the loser is usually the one you're advertising hardest.

What's in here: what pre-ad gross margin means · the floor by product type · why we turn work away below 20% · what margin actually buys you · why headroom should stay unspent · the discount stack that goes negative

A brand manager on my own team once argued that a new client should price below our margin floor, because otherwise the product would be too expensive for Amazon. He'd already said it to the client, after I'd sold them the opposite. His reasoning was the one you hear everywhere, which is that Amazon is a price-driven platform and premium products lose there.

I disagree with him, and the disagreement is the most useful thing I can hand you, because it's the decision that determines whether this channel ever pays you.

Your pre-ad gross margin is what a single unit keeps after true landed COGS and Amazon's fees, before any advertising, and for a consumables brand it needs to clear 30%. Below that, the channel can't carry the cost of competing on it.

What is pre-ad gross margin, and why not just use profit?

Pre-ad gross margin is the sale price minus two things: your true landed cost of goods, and Amazon's fees. Nothing else. No advertising, no agency fee, no overhead.

It's deliberately narrow, because the question it answers is narrow. If you listed this product on Amazon and did nothing at all, no ads, no promotions, just a live listing taking organic orders, what would you keep on each one? That number tells you whether the product can survive on this channel before you start spending to grow it.

Landed is the word doing the work in "true landed COGS." It's the product, the packaging, and the inbound freight to physically get a pallet into Amazon's network. Freight is where most spreadsheets fall down, because it's a cost people carry in their heads instead of on the sheet.

On the fee side, start with the referral fee, which varies by category and sometimes by price point within a category, so pull your own rate instead of assuming one. Then fulfillment, priced on size and weight, which is punishing on anything heavy. Then storage, including long-term storage and aged-inventory surcharges on anything slow moving.

The reason we build this number before anything else is that Amazon can't build it for you. Amazon knows what you sold and what it charged you. It has never seen your manufacturing invoice or your freight bill, so it can't do the subtraction.

What is a good profit margin on Amazon?

It depends on what you sell, and the difference between categories is larger than most brands expect.

Consumables: 30% pre-ad gross margin averaged across the catalog, and per SKU wherever you can hold it. That gives you enough room to advertise, discount, and pay for management while still keeping something.

Durable goods: 40% at the absolute floor, and closer to 50% to scale comfortably. Durables are harder because you can't lean on repeat purchase to rescue a thin first sale. A durable-goods brand running thin margins can't afford to join Amazon's sales events, so its advertising costs climb because it has to buy the traffic it can't earn.

Under 20%, on anything: the red zone. We won't take on a brand that insists on running margins this thin, and it isn't squeamishness. At 10% margin, I can deliver a five-to-one return on ad spend and you are still losing money. There's no marketing performance that rescues economics that broken, so the honest thing is to say no rather than take twelve months of fees on the way to an angry conversation with your CFO.

If you're sitting under 30% today, treat it as a starting position rather than a verdict on the business, because the fixes are usually pricing, pack size, or both. Most of the brands we work with came in below the floor.

What does margin buy you?

Your pre-ad gross margin is the budget for everything that happens next, which turns it from a score into a tool.

Once you know what a unit keeps, you know how much you can put into advertising before the channel stops contributing. You know what you can pay a partner to manage it. You know how deep a promotion can go on Prime Day without going backwards. You know whether a subscription discount is affordable. Every one of those decisions is downstream of one number, which is why we build it first and why we ask for your COGS before we'll run a single ad.

That last part surprises people. We've required knowing a brand's cost of goods before starting marketing for years now, and we adopted the rule after doing a few laps with brands where we got strong marketing results and the brand still made nothing, because the margins were too thin for good results to matter. Asking for COGS isn't diligence theater. It's the only way to know what performance target would even count as success.

If I have margin headroom, should I cut price?

Usually not, and this is where I part company with most advice on the subject.

I audited an account recently with roughly 15% of pricing headroom above the floor on two SKUs. The obvious move is to spend it, drop the price, and buy conversion. I recommended against it on both.

Unspent margin is promotional flexibility, and promotions do more for you than a permanently lower everyday price. Hold the headroom and you can go deep on Prime Day, run Black Friday properly, discount hard when you need to clear aged inventory, and drop price aggressively for a few weeks after a stockout to rebuild ranking. Spend the headroom on everyday price and you have none of those levers when you need them, and you've reset customer expectations at the lower number permanently.

There's a version of this that goes badly wrong, and I saw it on an account where four reasonable-looking decisions stacked. Base pricing set low to match mainstream competitors. Then 20% off one-time purchases. Then a subscribe-and-save discount. Then a coupon on top of the subscription. Nobody made a bad call in isolation, and the account was running at roughly negative 30% margin on some SKUs and closer to negative 37% on subscriptions. Every discount was defensible. The stack was fatal.

Can a premium product win on Amazon?

Yes, and I'll give you the account that settled the argument on my own team.

A brand in a category with mainstream competitors priced well below them came to us after an agency had been dropping prices to chase velocity. We raised prices, respected the pack sizes, cleaned up the Buy Box, and ran advertising that was answerable to the P&L. That brand now holds three of the top five spots in its category in a given month, at a higher price per ounce than the competitors underneath it.

The mechanism isn't clever. Price is one input into a purchase decision, and it stops being the deciding one as soon as the listing gives a shopper a reason to prefer you. That reason has to be visible on the page, in the images and the A+ content, because a shopper comparing two products is comparing two listings rather than two products.

Where premium does fail is when the brand is priced against the wrong shelf. I audited a clean, organic household product priced to compete with conventional mainstream brands, where it looked expensive and undifferentiated. Against other clean products it was underpriced. Same product, same price, and the comparison set decided whether it read as premium or overpriced.

Frequently asked questions

What is a good profit margin for selling on Amazon?

For consumables, 30% pre-ad gross margin across the catalog gives you room to operate. Durable goods need 40% at the floor and closer to 50% to grow comfortably, because they can't rely on repeat purchase. Anything under 20% is the range where we'd tell you the channel can't carry advertising and still come out ahead.

How do I calculate my Amazon profit margin?

Take the sale price for one SKU and subtract true landed COGS, which is product plus packaging plus inbound freight, then subtract Amazon's fees, which are the referral fee, fulfillment by size and weight, and storage. Leave advertising and agency fees out of this first number deliberately, so you can see the baseline before spend muddies it. Amazon publishes a revenue calculator that will give you the fee side once you plug in dimensions and price.

Why does Amazon not show me my profit?

Because it doesn't hold your costs. Amazon knows your sale price and its own fees, but it has never seen what you paid your manufacturer or your freight carrier, so it can't complete the subtraction. The revenue screen is honest, it's just answering a different question than the one you care about.

Should I lower my price to compete on Amazon?

Rarely, and almost never as a first move. Check what you're being compared against before you touch price, because a product priced against the wrong set of competitors can look expensive while being underpriced for the shelf it actually belongs on. If you do have headroom, it's usually worth more as promotional flexibility than as a lower everyday price.

What if my margin is below 30% right now?

That's the position most brands come to us in, and the fixes are ordinary. Reprice off awkward fee thresholds, change pack size so the economics work at a price the market accepts, rebalance a low-margin trial SKU against higher-margin ones, or renegotiate landed costs. What we won't do is run marketing on top of margins that can't support it and call the result a strategy.

Do I need per-SKU margin or is a catalog average fine?

Per SKU. A blended average hides the loser inside the winner, and in most catalogs the thin-margin SKU is the one getting the most ad spend, because it's usually the cheapest and therefore the best converter. The average looks healthy while the money leaks from one product.

The bottom line

Most Amazon strategy arguments that go in circles are margin arguments nobody has run the numbers on. Whether to advertise, whether to discount, whether an agency is affordable, whether the channel is worth the trouble at all, they're the same question asked four ways, and one number answers it.

Send us your COGS and product dimensions and we'll tell you where each SKU lands against the floor. It takes us very little time and you'll have the number whether or not you ever work with us.

You built a product people want. This is just the arithmetic that decides whether Amazon lets you keep any of it.
