Six tabs, six retypes, six numbers to reconcile by hand — and the reconciliation, not the arithmetic inside any one tab, is where a seller gives up and guesses. This page runs one item through eBay, Etsy, Amazon, Walmart, TikTok Shop, and your own store at once and ranks what each one actually leaves you, free and in your browser.
Every marketplace publishes a calculator scoped to its own fees, and on its own fees each one is the authority. It is maintained by the company that sets the schedule, it knows category exceptions, and it can see account-level terms — a store subscription tier, a promotion — that no outside page can. What it cannot do is rank, because it has no figure for what a different channel would have left you and no reason to produce one.
So a seller holding one unlisted item opens six calculators, types the same price and cost into each, writes six numbers down, and compares them by eye. That last step is the one this page replaces: type the item once, and every channel is ranked on the same model at the same time.
| What you want to know | Where to answer it |
|---|---|
| I have decided to list on this one marketplace. Exactly what will its fees be on my account, in my category? | That marketplace's own calculator — it is the authority on its own schedule, and this page is not. |
| I am holding one item and have not listed it anywhere. Which channel leaves me the most? | This tool — type the item once and every channel is ranked side by side on the same fee model. |
| Is a channel's monthly plan worth it at the volume I actually sell? | This tool — it spreads the subscription over the orders you typed, so a low-volume seller sees the real per-order cost. |
| Does the category I am selling in change which channel wins? | This tool — category is a required input, because two channels can charge very differently on the exact same item. |
| Do I need an account, a subscription, or a sign-in to compare? | This tool: none of the three. It is a static page and the arithmetic runs in your browser. |
Each of these is a difference between channels, and a single-channel calculator has no reason to mention a difference within its own channel it does not have.
Two of the six channels compared here set their referral rate by product category; the rest charge one flat rate regardless of what is being sold. That means the same item can sit at a low rate on one channel and a meaningfully higher rate on another for a reason that has nothing to do with either channel's headline number — and a seller comparing headline rates from memory has no way to catch it, because the headline rate is not what the category-priced channel actually charges. This page asks for the category before ranking anything so that difference is in the comparison rather than hidden behind it.
A flat subscription does not change with the sale, so it cannot be turned into a per-order cost without knowing how many orders the month will hold. At low volume it can be the largest single cost on the item; at high volume it rounds toward nothing. A calculator scoped to one order has no monthly figure to spread it over and either omits the subscription or attributes the whole month to the one item on screen. This page asks for expected monthly orders and amortizes every subscription across them, so a plan is compared as what it actually costs at your volume rather than at an assumed one.
Every channel compared here charges its percentage on the item price plus whatever shipping the buyer was charged, not on the item price alone. Folding postage into the price to advertise free shipping does not avoid the fee — it is still charged on the total the buyer paid. A quick mental estimate against the item price alone therefore understates every channel's fee by the same missed amount, which cancels out only if every channel is estimated the same wrong way and does not cancel out at all once shipping charges differ between listings.
A fourth difference belongs here too, and it is covered on the tool itself rather than repeated in full: your own store almost always tops a fee-only comparison, because it charges no referral fee at all — and it also sends you no buyers, so that figure only holds for a sale you brought yourself.
The honest half of the comparison. On the question it is built for, a marketplace's own calculator beats this page, and a seller who uses only this one is missing things:
So the sequence that gets the most out of both is: rank the channels here while the item is still unlisted, then confirm on the winning channel's own calculator with your own account's rates before you set the price. This page makes no claim about any marketplace calculator's accuracy or current terms, and does not evaluate one — it describes only the shape of what each kind of tool is for.
No account and no sign-in: this is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off. Nothing you type is uploaded.
Each one answers a single channel completely and correctly: what will this item cost me here? None of them can answer where should I list this, because none of them has a figure for what a different channel would have left you, and no reason to produce one. Getting from six correct single-channel answers to a ranking means opening six tabs, retyping the same item six times, and reconciling six numbers by hand — and that reconciliation, not the fee arithmetic inside any one tab, is where a seller gives up and guesses.
Three things, and each is easy to miss when you are eyeballing rate cards rather than running the numbers side by side. Some channels price a category by a flat percentage; others set the referral rate by category, so the same item can sit at a low rate on one channel and a high rate on another for a reason that has nothing to do with the channel's headline number. A monthly subscription is not a per-order fee, so it only becomes comparable to a percentage once it is spread over the orders you actually expect that month — at low volume it can be the largest line item, and a calculator scoped to one order has no volume to spread it over. And every percentage here applies to the whole order the buyer pays, item plus any shipping they were charged, which a quick mental estimate against the item price alone will understate.
No, and on its own fees a marketplace's calculator should be treated as the authority. It is maintained by the company that sets the fees, reflects the schedule currently published, and can see category exceptions and account-level terms this page cannot. The rates here are editable defaults that were current when this page was written, not a live fee schedule. What this page adds is not precision on one channel — it is one consistent model applied to all of them at once, so the numbers being compared were produced the same way.
That is the honest order to use them in. Run the comparison here first, while the item is still unlisted, to see which one or two channels are worth the effort at all. Then open the winning channel's own calculator to confirm against your actual account — your real category, any negotiated or promotional rate, your store subscription tier. The two are sequential, not competing: a ranking across channels, then a confirmation on the one you picked.
No. This site is not affiliated with, endorsed by, or sponsored by any marketplace named on it. Those names are used only to say which channels the comparison covers and to describe the publicly documented shape of each one's fees. No marketplace's calculator is reproduced, quoted, or evaluated here.
Open the marketplace fee comparison to rank your own item, read which marketplace has the lowest fees for a worked example, or see this tool vs. Sellerboard for the difference between a pre-listing ranking and connected seller analytics.
Fee rates change. The defaults in the comparison tool were current when it was written and are inputs, not a fee schedule. Confirm against your own statement, or the marketplace's own calculator, before pricing a catalogue against them.
