How is net per unit calculated?
Retail minus base cost minus platform fee, where the fee is a percentage plus a fixed per-order charge. Illustrative $32 tee nets about $15.84.

The margin is fine. The volume is the problem.
Print-on-demand removes inventory risk, which is the thing that kills most clothing brands. What it does not remove is the arithmetic: a good margin on a product nobody has heard of still earns nothing.
Every figure below is an illustrative example of the arithmetic, chosen to be realistic in shape. They are not quotes from any specific supplier and they are not results from any brand. Suppliers price differently by garment, print area, colour count, and region — run your own numbers against a real quote before deciding anything.
The three numbers
Print-on-demand economics reduce to base cost, retail price, and platform fee. Everything else is a variation on those three.
- Base cost — what the supplier charges to print and ship one unit. Rises with garment quality, print area, number of print locations, and colour count.
- Retail price — what you charge. The only lever you fully control, and the one most people set too low out of nerves.
- Platform fee — the storefront's cut plus payment processing. Typically a percentage plus a fixed per-transaction charge.
A worked example on a tee
Illustrative numbers: a mid-weight tee with a single front print, retailing at $32, on a storefront taking 5% plus roughly 3% payment processing and $0.30 per transaction.
| Line | Amount | Note |
|---|---|---|
| Retail | $32.00 | Customer pays this plus shipping |
| Base cost (print + fulfilment) | −$13.30 | Garment, print, pick and pack |
| Platform + processing (~8%) | −$2.56 | Illustrative blended rate |
| Fixed transaction fee | −$0.30 | Per order, not per item |
| Net per unit | $15.84 | About 49% of retail |
The same math on a hoodie
Hoodies carry a much higher base cost, so the percentage margin compresses even though the dollar margin grows.
| Line | Amount | Note |
|---|---|---|
| Retail | $58.00 | |
| Base cost | −$19.20 | Heavier garment, larger print area |
| Platform + processing (~8%) | −$4.64 | |
| Fixed transaction fee | −$0.30 | |
| Net per unit | $33.86 | About 58% of retail |
Read those two tables together and the first real lesson appears: the hoodie earns more than twice the dollars per sale, which matters far more than the percentage. Percentages do not pay rent; dollars per order do. This is why brands push toward higher-ticket items and multi-item carts rather than optimising a tee's margin by a point.
The volume problem
$15.84 a shirt sounds fine until you multiply it.
| Units sold / month | Gross margin at $15.84 | What that actually is |
|---|---|---|
| 10 | $158 | A hobby |
| 50 | $792 | A meaningful side income |
| 200 | $3,168 | A part-time job with real operational load |
| 1,000 | $15,840 | A business, with staffing and support needs |
Selling 200 shirts a month is not a design problem. It is a distribution problem — audience, content cadence, repeat customers, and retention. Print-on-demand solves inventory risk and solves nothing about demand, and demand is the part that is genuinely hard. The people who quit usually quit with a good product and no traffic.
The costs nobody puts in the spreadsheet
| Hidden cost | Typical shape | Effect on net |
|---|---|---|
| Returns and reprints | A few percent of orders, often on you rather than the supplier | Shaves a few percent off net across all units |
| Samples | One unit of each product, at your own cost, plus shipping | A fixed upfront spend before any revenue exists |
| Artwork time | Hours per design, plus mockups and revisions | Free only if your time is worthless |
| Ads | Cost per acquisition frequently exceeds net per unit on a single item | Can turn a positive-margin product into a loss |
| Shipping expectations | Customers expect free or cheap shipping | Either raise retail or absorb it out of net |
| Payment disputes | Chargebacks carry the refund plus a fixed fee | Small in volume, painful per event |
| Platform changes | Base costs and fee rates get revised | Your margin is quietly repriced by someone else |
The one that ends most stores is the ads line. If net per unit is $15.84 and it costs $22 in ads to acquire a customer who buys one item, every sale loses money — and that only becomes visible after you have spent enough to see it. The escape routes are higher average order value, repeat purchases, or acquisition that does not cost money per unit, which is what organic content actually is.
Pricing, briefly
- Start from the net you need, not from what competitors charge. Work backwards to retail.
- Price the bundle, not the item. The fixed transaction fee is per order, so a two-item cart is structurally more profitable.
- Do not compete on price against a supplier that has scale you do not. You will lose, and you will lose on your own margin.
- Recheck after every supplier price change. Base costs move; retail prices usually do not until someone notices.
- Treat free shipping as a price increase, because it is one. Fold it into retail deliberately rather than absorbing it silently.
Why print-on-demand is still the right start
Held against the alternative, the case is strong. Bulk ordering 200 units means several thousand dollars committed before a single customer exists, a size curve guessed in advance, and boxes in a room. Print-on-demand trades roughly a third of the per-unit margin for zero inventory risk, no minimum order, and the ability to kill a design that does not sell without eating the stock.
For testing whether a design has an audience at all, that trade is clearly correct. Move to bulk only once a specific item has demonstrated repeat demand — and at that point the higher margin is earned by evidence rather than assumed. This is the model behind KXNG SEF and HEFT: no inventory, no minimums, designs that do not sell simply stop being printed.

FAQ
Quick answers
What margin is realistic?
Illustratively 45–60% of retail after base cost and fees. Depends entirely on supplier, garment, and print area — get a real quote.
Is it profitable?
Per unit yes, in total only at volume. 10 shirts a month is a hobby, 200 is a part-time job. POD fixes inventory risk, not demand.
What costs get forgotten?
Returns, samples, artwork hours, free shipping, chargebacks, and ads. Ad cost per customer often exceeds net per single item.
Tees or hoodies?
Hoodies. Illustratively $33.86 net against $15.84, and the fixed fee is per order — so higher ticket and bigger carts win.
POD or bulk?
POD to start. Bulk commits thousands and a guessed size curve upfront; POD trades about a third of margin for zero inventory risk.
