The useful move is not to add more lines to the per-order calculation. It is to sort every cost by what it scales with, because that determines which decisions can move it. A cost that scales with units is fixed by pricing or sourcing. A cost that scales with designs is fixed by deleting listings. A cost that scales with months is fixed by cancelling something. Lumping them into one percentage hides which lever applies.
There are six classes. Three of them appear in a per-order margin. Three do not.
Supplier cost
scales with unitsin the marginThe base cost to make the item and the supplier's charge to fulfil and ship it. Straight variable cost: double the units and it doubles exactly. It is also the class with the least room for negotiation at small scale, because you are quoted a rate card rather than a price.
Note that base costs are not published as a single figure — they change with the print provider, garment, size, print area and fulfilment region, and some suppliers only quote inside a logged-in account. Any figure you have not read in your own dashboard today is a guess.
Percentage marketplace fees
scales with revenuein the marginEtsy's US rates as of July 2026: a 6.5% transaction fee, and Etsy Payments processing at 3% plus a fixed component. Offsite Ads, when it attaches, adds 15% of the order total — 12% for shops past $10,000 of sales in the previous 365 days. These scale with price rather than with volume, which is why raising a price is such an efficient lever: you keep 93.5 cents of every extra dollar against the 6.5% transaction fee alone.
Fixed per-order and per-unit fees
scales with ordersin the marginThe fixed slice of payment processing, and Etsy's $0.20 listing fee. The listing fee has a detail that matters for multi-quantity listings: Etsy charges $0.20 to publish and another $0.20 each time an item sells while quantity remains, so a buyer taking five of something costs $1.00 rather than $0.20. A per-order calculator that models one unit will understate a bundle.
Catalogue upkeep
scales with designsoutside itThis is the class that has no equivalent in a physical-inventory business and the one nobody models. An Etsy listing expires after four months and renews for $0.20, so keeping a design live costs about $0.60 a year whether it sells or not — roughly $60 a year per hundred listings.
A catalogue of three hundred designs is therefore a standing bill of around $15 a month before anyone buys anything, and it grows every time you upload. It is trivially small per listing, which is exactly why the strategy of uploading everything and seeing what sticks feels free. It is not free; it is a subscription you took out on your own dead stock.
Subscriptions and tooling
scales with monthsoutside itDesign software, mockup generators, a storefront plan, a supplier's premium tier that lowers base costs. All of it is real and none of it appears in a per-order number until you divide it by the orders you actually shipped. A supplier subscription that shaves a dollar off base cost is worth having at 200 orders a month and is a straight loss at 10.
Failures
scales with orders, unpredictablyoutside itReprints, lost parcels, returns. Custom-printed goods generally cannot be resold, so a return is a total loss on the item rather than a restock. And the fee treatment on a refund is not symmetrical: Etsy credits fees proportionally when you refund an order yourself, but its policy states that where a full refund is covered by Etsy, the processing fee and other applicable fees — transaction, Offsite Ads — are not credited back. A refunded advertised order can therefore lose the sale and keep the fees.
The same shop, counted twice
Here is what the difference looks like on one month. The per-order figures below are the ones the POD profit calculator returns for a t-shirt costing $10.85 to make and $4.50 to ship, listed at $24.99 with free shipping on a marketplace taking 6.5% plus $0.20: a net profit of $7.82 and a margin of 31.3%.
Every number in this month is illustrative. The $10.85 and $4.50 are stand-ins, not quotes — supplier pricing only exists inside your own account. The order count, catalogue size, subscription total, reprint rate and ad spend are invented to make the arithmetic legible. The Etsy fee rates are real. Replace all six of the invented figures with yours before drawing any conclusion about your own shop.
| One month, 40 orders of one unit each | Amount |
|---|---|
| Revenue — 40 × $24.99 | $999.60 |
| Per-order contribution — 40 orders at $7.8157 unrounded | $312.63 |
| Catalogue upkeep — 300 live listings at ~$0.60/year | −$15.00 |
| Subscriptions — design and mockup tooling | −$30.00 |
| Failures — 3% of orders written off at supplier cost | −$20.00 |
| Advertising — total spend for the month | −$120.00 |
| What the month actually produced | $127.63 |
Same shop, same orders, same products. $3.19 of profit per order instead of $7.82, and 12.8% of revenue instead of 31.3%. Nothing in the first calculation was wrong. It was answering a different question.
The break-even that matters is not the one you were shown
A per-order calculator gives you a break-even price: on the figures above, $16.63 — the point at which the percentage fee swallows exactly what the shirt and the postage left behind. Useful when you are pricing a product.
The monthly view gives you a break-even volume. Strip out advertising, which scales with ambition rather than with the shop existing, and this shop carries $45 a month of costs that arrive whether or not anything sells. At $7.32 of contribution per order after the reprint allowance, it needs about six orders a month to cover them.
Six is a low number, and that is the finding. The fixed stack in print-on-demand is genuinely small — which means when a POD shop is not profitable, it is essentially never because of subscriptions or listing fees. It is the variable stack: supplier cost as a share of price, and the cost of buying traffic.
The unit nobody counts: the design
Forty orders spread across three hundred designs is not forty orders spread across three hundred designs. It is a handful of designs selling repeatedly and a long tail selling nothing, which is the normal shape of a print-on-demand catalogue and the reason the per-design class deserves its own arithmetic.
Give a design forty minutes of your time — research, artwork, mockups, writing the listing — and value that time at $20 an hour. That is $13.33 of labour embedded in a listing that will be live for four months before it needs renewing. At $7.82 of contribution per sale, a design has to sell about twice in its first four months to repay the time that made it, before it has contributed anything at all.
Most will not. That is not a failure of the model; a catalogue business is a portfolio where a minority of items carries the rest. But it does change what “profitable” means: the question is not whether a shirt has a 31% margin, it is whether your hit rate — the share of designs that clear two sales — is high enough that the winners repay the losers. That number is knowable from your own sales history and almost nobody calculates it.
It also gives catalogue hygiene an actual value. A listing that has produced zero sales in twelve months has cost you $0.60 in renewals and whatever your time is worth, and will keep charging the $0.60. Deleting it is not tidying; it is the only cost reduction available in a class where there is no supplier to negotiate with.
Which lever is worth pulling, in order
Ranked by what each does to the month above.
- Price. Moving from $24.99 to $29.99 takes net profit per order from $7.82 to $12.49 — a $5 rise delivers $4.67, because the only thing taking a cut of the increase is the 6.5%. Across 40 orders that is $187 a month, more than the whole non-advertising cost stack. It is also the hardest, because it has to survive contact with what buyers will pay.
- Advertising efficiency. The largest single line in the ledger. Divide spend by the orders it actually produced rather than by all orders, and you get a cost per acquired order you can compare against $7.82 of contribution. If it is above that number, the advertising is buying revenue and selling profit.
- Supplier cost. Every dollar off the base cost is a dollar of profit, with no fee taken — full pass-through, unlike a price rise. Worth revisiting when a provider changes rates or when a different fulfilment region becomes viable.
- Shipping presentation. Neutral on fees and not neutral on conversion. Marketplace fees apply to shipping revenue as well as item revenue, so moving postage inside or outside the price does not change what you pay — only which number the buyer sees.
- Catalogue hygiene. Small in absolute terms and worth doing anyway, because it compounds quietly and because the exercise of finding the dead listings is how you discover your hit rate.
- Subscriptions. Last, and only worth auditing once, unless a tool's cost has grown past what it saves.
Two things this framework still cannot see
Currency, if your supplier bills in one currency and your marketplace pays out in another. Two conversions are happening and neither is at the mid-market rate you see quoted; the spread hides inside the exchange rate rather than appearing as a fee line, which is why it goes unnoticed. Compare a month of payouts and invoices against the mid-market rate for the same dates and treat the gap as a standing reduction.
And timing. A month that produced $127.63 has not necessarily paid you $127.63 — funds sit in a marketplace payment account before they reach a bank, and new shops in particular wait, which the route from sale to bank transfer covers separately. Profit and cash are different problems and the second one is what actually stops small shops from restocking.
For the per-order half of all this, the POD profit calculator handles the supply side and the fee calculator the marketplace side. The monthly half is a spreadsheet, and it is worth twenty minutes a quarter.

Etsy's fee structure — the $0.20 listing fee, the four-month listing expiry, the additional $0.20 charged when an item sells from a multi-quantity listing, the 6.5% transaction fee, Etsy Payments processing, and Offsite Ads at 15% or 12% above $10,000 of sales in the previous 365 days — is from Etsy's Fees & Payments Policy and Fees and Listing Multiple Quantities. The asymmetric treatment of fees on refunds is from Refunds, Returns and Exchanges for Sellers and the Etsy Payments Policy.
