The short answer
Most print-on-demand platforms tell you the royalty rate. Almost none tell you the royalty base — and that single omission is the reason your payout never matches your expectation.
Here is the honest version: on a typical $15 item, a designer earning a "30% royalty" does not receive $4.50. They receive closer to $3.20, because the base is not the retail price. It is the retail price minus the freight baked into it.
Below is a full breakdown using real cost data from a 43-product catalog — the actual manufacturing costs, freight tiers, and margin structure that most platforms treat as a trade secret.
Why the royalty base matters more than the rate
A royalty is always calculated as:
Earnings = (Royalty base) × (Royalty rate)
Platforms compete on the rate, because that is the number designers compare. But the base is where the real money is decided. There are three possible definitions, and they produce wildly different payouts on the same item:
| Base definition | On a $15 item at 30% | What it means for you |
|---|---|---|
| Retail price | $4.50 | Generous, rarely offered |
| Retail − freight | $3.20 | Honest, freight is a real cost |
| Retail − freight − platform fee | $2.40 or less | Common, and often undisclosed |
If a platform advertises "up to 50% royalty" but applies it to a base that has already had freight, payment processing, and a platform fee stripped out, the headline number is close to meaningless. Always ask what the base is.
What things actually cost to make
Here is the real cost structure behind a 43-product catalog spanning apparel, drinkware, wall art, phone cases, stationery and home textiles. These are landed manufacturing costs from Chinese production, before any retail markup.
| Product | Retail price | Weight class | Freight to US/EU |
|---|---|---|---|
| T-shirt | $15.70 | Medium (100–500g) | ¥26 |
| Mug | $9.40 | Heavy (0.5–2kg) | ¥42 |
| Hoodie | $31.25 | Heavy (0.5–2kg) | ¥42 |
| Postcard | $3.55 | Light (<100g) | ¥15 |
| A4 poster | $6.85 | Light (<100g) | ¥15 |
| Phone case | $11.17 | Light (<100g) | ¥15 |
| Blanket | $32.20 | Oversize (>2kg) | ¥68 |
Weighted across the whole catalog with a realistic product mix, the blended figures are:
- Average retail price: $14.88
- Average manufacturing cost: $3.05
- Average freight cost: $4.14
That freight number surprises most designers. On a $15 item, freight is roughly 28% of the retail price — larger than the manufacturing cost itself. This is the single most under-discussed number in print on demand.
How retail prices are actually built
Most platforms use some version of a tiered markup on manufacturing cost, plus freight with a handling buffer:
Retail = (Manufacturing cost × Tiered markup) + (Freight × 1.15)
The tiered markup exists because a flat percentage produces absurd prices at the extremes — a 3× markup on a $0.50 sticker is nothing, while 3× on a $40 blanket is unaffordable.
| Manufacturing cost | Markup multiplier |
|---|---|
| $0 – $1 | 5.5× |
| $1 – $3 | 4.2× |
| $3 – $7 | 3.2× |
| $7 – $15 | 2.6× |
| $15 – $35 | 2.2× |
| $35 and up | 1.8× |
The 1.15 multiplier on freight covers packaging materials and the handling labour that carriers do not itemise.
Why the base is (retail − freight)
Freight is a genuine, unavoidable, per-unit cost. If a platform paid royalties on a base that included freight, it would be paying designers a percentage of a cost it has to pay out to someone else — on every single order. That is not a business; that is a short path to insolvency.
So the defensible base is:
Royalty base = Retail price − Freight
One useful property of this formula: it is destination-independent. A mug shipped to Germany costs more to freight than the same mug shipped to California, but because tax is applied to retail and the royalty base excludes freight, the designer's earnings per item stay identical regardless of where the buyer lives.
What you actually earn
Using the blended catalog figures — $14.88 average retail, $4.14 average freight — the royalty base is $10.74 per item. Here is what that produces at each tier:
| Royalty rate | You earn per item | Your share of retail |
|---|---|---|
| 10% | $1.07 | 7.2% |
| 20% | $2.15 | 14.4% |
| 30% | $3.22 | 21.6% |
| 40% | $4.30 | 28.9% |
| 50% | $5.37 | 36.1% |
Note the gap between the headline rate and the share of retail. A "30% royalty" is really about 21.6% of what the buyer paid. This is not deception — freight is genuinely expensive — but it is the number you should plan around.
For comparison, the platform's own contribution per item at a 30% royalty is about $4.46, or 30% of retail. The remaining cost structure is manufacturing ($3.05), freight ($4.14), payment processing, and refunds.
The costs that quietly eat your margin
The royalty is not your profit. If you are running this as a business, four more things come out of it:
- Payment processing. Typically 2.9% + $0.30 per transaction. On a $15 order that is roughly $0.74.
- Refunds. A 3–5% refund rate is normal for custom goods. Budget for it.
- Design time. If a design takes three hours and sells four units at $3.22, your effective hourly rate is $4.29. Most designers never run this calculation.
- Your own promotion. If you are waiting for the platform's marketplace to surface your work, you are competing with thousands of other listings. The designers who earn meaningfully are the ones who bring their own audience.
That fourth point is the one that separates hobby income from real income.
Multi-item orders work in your favour
Freight does not scale linearly. The first item in an order carries full freight; each additional item carries roughly 35% of full freight, because they ship together.
Because retail prices are built per item with full freight embedded, this means multi-item orders are structurally more profitable than single-item orders. A customer buying three mugs generates more margin than three customers buying one mug each — even at identical royalty rates.
This is why bundled listings, matching sets, and "complete the collection" recommendations are worth more effort than chasing single-unit volume.
What to ask before you commit to a platform
Cut through the marketing with these five questions:
| Ask this | Why it matters |
|---|---|
| What is the royalty base — retail, or retail minus freight? | Changes your payout by 25–30% |
| Are there per-item or monthly platform fees? | Often hidden behind "free to start" |
| Is shipping charged to the buyer on top? | Determines conversion, and therefore your volume |
| What is the real production-to-delivery time? | Anything over 12 days to the US drives chargebacks |
| Can I see my earnings per item before publishing? | If not, you cannot make pricing decisions |
FAQ
Is a 50% royalty realistic? Yes, but understand what it applies to. At 50%, you earn about $5.37 on an average $14.88 item — roughly 36% of what the buyer paid. That is genuinely good, but it is not half the retail price.
Why does freight cost more than manufacturing? Because you are shipping a single, bulky, fragile item internationally, not a container of 500. Per-unit freight for a 300g mug is structurally expensive in a way that bulk retail never is.
Do I earn the same if the buyer is in Europe? Yes, when the base excludes freight. Tax is applied to the retail price at checkout, and the royalty base is defined before tax, so earnings per item are identical regardless of destination.
When do I actually get paid? This varies. Look for platforms that pay out on a defined settlement cycle rather than requiring you to reach a threshold balance, which can leave earnings stranded for months.
The bottom line
If you take one number from this article, take this one: on an average $15 item, expect to earn around $3.20 at a 30% royalty — about 21.6% of retail.
That is a real, honest number, and it is enough to build a meaningful income if you treat it as a volume business rather than a lottery. The designers who do well are not the ones who found the highest royalty rate. They are the ones who understood the base, priced with eyes open, and built an audience they did not have to rent.
