Why a $20 Product and a $100 Product Can’t Have the Same TACOS

A $20 product and a $100 product can both end up at 5% TACOS. Nothing stops them. What they can’t do is get there the same way.

If it costs both sellers the same amount to buy a customer through advertising — and it usually does — then the two businesses need completely different mixes of paid and organic sales to arrive at that same 5%. One of them needs almost all its customers to find it on their own. The other doesn’t. That’s the whole article, and everything below is the arithmetic, of which there is less than you’d expect.

01What a sale from advertising actually costs you

Two numbers decide it, and you can find both: what you pay for a click, and how many clicks it takes to make one sale.

That is the entire calculation.

Every example below uses a $1 click and a 10% conversion rate, which gives $10 per advertising sale. That is an illustration, not a law. It sits in the middle of what is published: Ad Badger reports an average click cost of $1.22 for 2026, Skai reports $0.96, Autron $1.13, and Two Minute Reports finds most medians between $0.50 and $0.75 across more than a thousand advertisers. Conversion rates published for Sponsored Products cluster around 10–15%.

Amazon itself doesn’t publish an average, and says plainly that there isn’t a set number, because click costs come out of an auction.

02Now turn that into TACOS

TACOS asks: out of all the money you make, how much went to advertising? A 5% TACOS means $5 of every $100 you sell went to ads.

Here is the piece worth memorising. When a product is brand new, almost nobody finds it on their own, so nearly every sale comes from advertising. Which means launch TACOS is roughly the cost per advertising sale divided by your selling price.

Look carefully at that table, because of what did not happen. The click cost didn’t change. The conversion rate didn’t change. The campaign, the keywords, the bidding, the skill of the person running it — none of it changed.

03The same thing, counted out

If formulas aren’t your thing, count it instead.

You sell 100 units of a $20 product. That’s $2,000. A 5% TACOS gives you $100 to spend on ads. At $10 a sale, ads can buy you 10 sales. The other 90 have to arrive on their own.

Same exercise with a $60 product. 100 units is $6,000. 5% gives you $300. Ads buy 30 sales, so 70 are organic.

A $100 product. 100 units is $10,000. 5% gives you $500. Ads buy 50 sales, and 50 organic is an ordinary, healthy mature listing.

At $200, every single sale can be bought and you still report 5%. At $20, nine in ten must walk in by themselves.

04Two sellers, same TACOS, completely different situations

This is the clearest demonstration that TACOS alone tells you very little.

Both have a 5% TACOS. Identical. But Seller A is spending $5,000 to generate $10,000 of ad sales, an ACOS of 50%. Seller B is spending $5,000 to generate $50,000, an ACOS of 10%. One of them is buying sales at five times the cost of the other, and the TACOS number hides it completely.

05Benchmark is not the same as target

Worth pausing on, because this is where most beginners go wrong.

A benchmark describes what some group of sellers experienced. A target is what your business should aim for. They are different things, and a benchmark from someone else’s business is not a target for yours.

So when you hear “5% TACOS is normal,” the useful response isn’t disagreement. It’s a question: normal for whom? At what selling price, in what category, at what click cost and conversion rate? What share of the sales is organic? How old is the listing? Is that one product or a whole account, before or after promotions?

Until you know those, 5% is just a number.

Helium 10 is interesting on this. Its general explainer says outright that there is no specific example that results in a good TACoS, while another Helium 10 page gives a target of 15–22% for growth-stage brands. Same company, two answers, and the second is three times higher than what the agencies quote.

That disagreement is the real finding. If the experts published a consistent number, you would expect them to agree.

06Amazon takes a smaller cut as your price rises

There is a second effect, and it works in the same direction.

Amazon charges you two things: a referral fee, which is a percentage of your price, and a fulfilment fee, which is based on the size and weight of your box, not on what’s inside it. Imagine a simple version, 15% referral plus about $4 to pick, pack and ship.

The fulfilment fee didn’t go up fivefold when the price went up fivefold. It barely moved.

Here is the same thing with current published figures, for one specific illustrative product: Home & Kitchen category at 15% referral, large standard size, 4–8 oz shipping weight, US marketplace, standard non-peak rates.

07So what can each product actually afford?

One more assumption finishes the picture: what the product costs you to land in Amazon’s warehouse.

Assume a landed cost of one third of the selling price. Many sellers use a rough 3x rule — sell for about three times what the product costs you delivered — and it is borrowed here purely as a worked example. It is a common convention, not a rule of Amazon’s and not a finding from research. Your own number is the one that matters, and Amazon’s own guidance advises pricing on value rather than a fixed markup.

That last row is your ceiling. Spend more than that on advertising and you are paying customers to take the product off your hands. Now put the two tables together.

Under these assumptions the $20 product cannot support advertising on its own at launch. Not because you are bad at PPC. Because $10 doesn’t fit inside $6.38. The $60 and $100 examples can carry their advertising from the first week, before any organic sales exist.

08So how does anyone sell cheap products?

Plenty of people do, and do well. But look at what it takes.

A $20 product only reaches 5% TACOS when about 90% of its sales arrive organically. You don’t get to 90% organic by waiting. You get there through ranking, reviews and sales history, most of which is built while advertising carries the listing.

Say a seller does $120,000 a year: 6,000 units at $20.

In this example, reaching that 5% took about $96,000 of advertising along the way.

Now the same $120,000 of revenue from a $100 product, which is 1,200 units. At 80% of sales from ads, that is 960 ad sales at $10 each: $9,600 a year, roughly 8% TACOS, from the first year.

09The part about money that nobody puts in the video

Here is where this stops being about advertising.

Both sellers above make $120,000 a year. The $20 seller moves 6,000 units at $6.67 landed. The $100 seller moves 1,200 units at $33.33 landed. Both spend exactly $40,000 on inventory.

That is not a coincidence. If landed cost is a roughly fixed share of your price, then the same revenue costs the same to stock, whatever you charge. The price cancels out.

Look at what it takes to place a first order of 500 units.

The advertising line doesn’t move. Selling 500 units costs about the same in ads whatever they are worth: 400 ad sales at $10. And on the $20 product, the advertising to sell your first order costs more than the order did.

Cheap products don’t necessarily need less capital. They need it in a different form, at a different time, and in the form you can’t get back. What happens when the product works and the cash doesn’t is the same arithmetic from the other side.

10So is 5% TACOS real?

Yes. The arithmetic above produces it.

It arrives on a product priced high enough that the cost of buying a customer is a small share of the sale, sold through a listing established enough to bring most of its own traffic, in a business that could fund the stretch in between.

Which is why the honest response isn’t “that’s not true.” It’s “5% of what kind of business?”

11The five questions

When someone tells you 5% TACOS is normal, you don’t need to argue. You need five answers.

1. At what selling price? A $20 and a $200 product have completely different advertising economics.
2. What’s the click cost? There is no universal Amazon CPC, and Amazon says so itself.
3. What’s the conversion rate? Click cost means nothing without it. The two together give cost per sale.
4. How old is the listing? A mature listing with strong organic traffic is a different proposition from one launched last month.
5. What’s left after product cost and Amazon’s fees? This is the one that decides whether any TACOS is affordable.

If they can’t answer those, don’t copy the number.

12About these numbers

Every figure here is public and checkable. Where the evidence is thin, this article says so rather than rounding up to a confident number. The links below go to the sources themselves.

Click costs. Amazon does not publish an average and states there is no set number, since click costs come from an auction. Every other figure is from an advertising software company reporting its own platform data, and each has a commercial interest in it.

• Amazon Ads, What is CPC (cost per click)?
• Ad Badger, Amazon Advertising Benchmarks 2026 — $1.22 average; category cost per sale $6.45–$15.26; 11.7% platform conversion rate

Conversion rates. These are Sponsored Products advertising conversion rates, which differ from Amazon’s own unit session percentage. Amazon publishes no average.

• Trellis, Amazon advertising benchmarks — 10–15% for Sponsored Products
• Sequence Commerce, Amazon advertising benchmarks — 10–12%
• Triple Whale, Amazon benchmarks — 2,800+ brands, August 2025 to July 2026, by category

Amazon fees. Referral fees are published by Amazon at sell.amazon.com/pricing. FBA fulfilment fees changed structure in January 2026, with price bands under $10, $10–50 and over $50, and carry a fuel and logistics surcharge from April 2026. The figures used here are for one specific size and weight: check your own product in Amazon’s Revenue Calculator or the Seller Central Fee Preview.

TACOS targets. All of these are published guidance, not measured averages. I could not find any industry-wide study establishing an average or target TACOS.

• ClearAds, ACOS and TACOS — 5–10% ideal
• Canopy Management, Ultimate guide to ACOS and TACOS — 5–10% mature
• Keywords.am, Amazon TACOS — 5–10% after 18 months
• Trellis, Amazon TACOS — 10–15% typical, 25–40% at launch
• Helium 10, What is Amazon TACoS? — no specific example results in a good TACoS
• Helium 10, How to allocate advertising budget across channels in 2026 — 15–22% for growth-stage brands

Seller economics. Jungle Scout, State of the Amazon Seller 2024: 1,064 active sellers and businesses analysed, surveyed December 2023 to January 2024. Jungle Scout sells seller software.

The 3x rule is a common convention among sellers, not research, and not an Amazon rule. Amazon’s own guidance advises against fixed markups.

Illustrative assumptions. The $1 click cost, 10% conversion rate, one-third landed cost, 500-unit first order and the four-year path from 40% to 5% TACOS are worked examples chosen to make the arithmetic visible. They are not benchmarks, forecasts or recommendations. No published data exists on how the organic share of a listing’s sales changes over time. If you see a confident figure for that anywhere, ask where it came from.
