Case study: the $32 mug that was earning $7.94
Every guide on this site explains one calculation. This walks one product through all of them, in order, showing the arithmetic at each step and what changed at the end.
The starting position
Maya throws ceramic mugs and sells them on Etsy. She has been going fourteen months, sells around 45 a month, and cannot work out why a business that looks busy leaves her so little. Her own view of the product is that it costs her "about nine dollars in clay and glaze" and sells for $32, so she assumes she makes something in the low twenties per mug.
Here is what she actually had:
| Item | Amount |
|---|---|
| Mug price | $32.00 |
| Shipping charged to buyer | $6.50 |
| Buyer pays | $38.50 |
| Clay and glaze | $2.90 |
| Kiln firing (share of electricity) | $1.10 |
| Labour — 35 min at $18/hr | $10.50 |
| Overhead per unit (studio, tools, insurance) | $1.20 |
| True unit cost | $15.70 |
| Real postage | $8.20 |
| Packaging (box, wrap, filler, label) | $1.35 |
| Handling — 4 min at $18/hr | $1.20 |
| Real cost of getting it there | $10.75 |
The first finding is already visible and it has nothing to do with fees. Her "about nine dollars" was materials and firing — $4.00 — with labour left out entirely. Her real unit cost is $15.70, because 35 minutes of her own skilled work is a cost whether or not she pays herself for it. This single omission is the most common error in handmade pricing, and everything downstream inherits it.
Step 1 — What Etsy actually takes
Four separate fees, applied to the full $38.50 the buyer paid, not to the $32 mug:
| Fee | Basis | Amount |
|---|---|---|
| Listing fee | Flat | $0.20 |
| Transaction fee | 6.5% of $38.50 | $2.50 |
| Payment processing | 3% of $38.50 + $0.25 | $1.41 |
| Total | $4.11 |
Note the transaction fee basis. Etsy's documentation states the 6.5% applies to the total cost of the item along with shipping when you charge the customer for it — so it lands on $38.50, giving $2.08 on the mug's share plus $0.42 on the postage she collected. Sellers who apply 6.5% to the item price alone under-count every single order that has postage on it.
Running the numbers with the Etsy fee calculator:
| Line | Amount |
|---|---|
| Buyer pays | $38.50 |
| Etsy fees | −$4.11 |
| Unit cost | −$15.70 |
| Shipping, packaging, handling | −$10.75 |
| Net profit per mug | $7.94 |
$7.94, not "low twenties" — a 20.6% net margin. She was overstating her profit by roughly three times. And she was not being careless: every individual number here is small and reasonable. It is the accumulation that does the damage.
Step 2 — The shipping leak
The largest single problem is not the fees. Put her postage through the shipping cost calculator:
| Line | Amount |
|---|---|
| Shipping charged | $6.50 |
| Fees taken on that shipping (9.5% combined) | −$0.62 |
| Actually left towards postage | $5.88 |
| Real cost of the parcel | −$10.75 |
| Shortfall per order | −$4.87 |
She is absorbing $4.87 of every order in shipping she does not recover. At 45 orders a month that is about $219 a month, or $2,628 a year — paid out of a business that nets under $4,300 a year in total. More than half her profit is going into parcels she believes the buyer is paying for.
Two things caused it. Her $6.50 charge was set from a postage rate that has since risen, and packaging and handling were never counted as shipping costs at all — they were invisible, because the boxes were bought in bulk months ago and the four minutes of wrapping felt like part of making the mug.
Step 3 — Repricing
She raises the mug to $38 and the shipping charge to $9. That feels aggressive — an 18.75% increase on a product that is already selling — and it is worth being precise about what it does rather than guessing.
| Line | Before | After |
|---|---|---|
| Mug price | $32.00 | $38.00 |
| Shipping charged | $6.50 | $9.00 |
| Buyer pays | $38.50 | $47.00 |
| Etsy fees | −$4.11 | −$4.92 |
| Her costs (unchanged) | −$26.45 | −$26.45 |
| Net profit per mug | $7.94 | $15.64 |
| Net margin | 20.6% | 33.3% |
Profit per order nearly doubled from a 22% increase in what the buyer pays. This is the leverage that makes repricing the highest-return action available to most small sellers: her costs did not move, so almost the entire increase landed in margin. Across 540 orders a year the difference is about $4,154 — from changing two numbers in Shop Manager.
The obvious fear is losing sales. Worth quantifying rather than fearing: at $15.64 a mug she could lose a third of her orders and still finish the year ahead of where she was at $7.94. That asymmetry — a large price rise needing only a modest retention rate to win — is what the guide on raising prices covers.
Step 4 — Was Etsy even the right channel?
With a properly priced product, the marketplace comparison calculator can rank her options on the same $47 order:
| Channel | Fees | Net profit | Margin |
|---|---|---|---|
| Her own store (at 45 orders/mo) | $2.53 | $18.02 | 38.3% |
| Amazon FBA | $13.45 | $17.85 | 38.0% |
| Etsy | $4.92 | $15.64 | 33.3% |
| eBay | $6.53 | $14.02 | 29.8% |
| Amazon FBM | $7.05 | $13.50 | 28.7% |
Her own store wins — $2.38 more per order than Etsy, about $1,285 a year. Two results in that table deserve more attention than the ranking, though.
Amazon FBA comes second despite charging by far the highest fees — $13.45 against Etsy's $4.92. It places well because the FBA fee replaces her postage, packaging and handling entirely, and those come to $10.75. The channel with the worst headline fee is nearly the best net outcome, which is precisely why comparing percentages instead of net profit misleads people.
Her own store's advantage is conditional on volume. That $2.53 includes $0.87 of monthly platform subscription spread across 45 orders. At 10 orders a month the same subscription costs $3.90 an order and Etsy wins comfortably. And Etsy brings buyers while her own store does not — a channel that nets $2.38 more per order is worth nothing if it produces no orders.
Her sensible conclusion was not to leave Etsy. It was to keep Etsy for reach and start putting a card in every parcel pointing repeat buyers at her own site — earning the higher margin from customers Etsy had already introduced her to.
Step 5 — The discount she was about to run
She had planned a 20% holiday sale. Through the discount impact calculator, at her new $38 price with $22.36 of variable cost per mug:
- Contribution per mug at full price: $15.64
- At 20% off ($30.40, with fees recalculated on the lower price): $8.76
- Volume increase needed simply to match the profit of not discounting: +79%
A 20% discount cut her contribution by 44%, so she would have needed nearly 80% more unit sales to stand still. Her realistic expectation was a lift somewhere around 30%. The sale would have felt like her best month of the year — more orders, more revenue, constant activity — and finished with less profit than doing nothing.
Note that the percentage fees fall with the price, which softens the blow slightly — a discount does not cost you the full face value, because Etsy's cut shrinks too. It is still nowhere near enough to rescue a 20% cut.
She ran a bundle instead: two mugs for $70 against $76 separately. The $6 discount buys her one parcel rather than two — saving a second lot of postage, packaging and handling — and one payment fixed fee instead of two. That is a larger saving than the discount costs her, so the bundle raised her average order value and her margin at the same time.
Where she ended up
| Measure | Before | After |
|---|---|---|
| Net profit per order | $7.94 | $15.64 |
| Net margin | 20.6% | 33.3% |
| Annual profit at 540 orders | $4,289 | $8,443 |
| Shipping absorbed per year | $2,628 | $0 |
Roughly double the annual profit, with no new customers, no advertising and no new product — from four changes: counting her labour, charging real postage, raising the price, and not running a discount that would have lost money.
None of this is unusual. The specific figures are invented; the shape is what shows up again and again. Sellers who feel their business is busier than it is profitable are almost always carrying some version of these four, and the reason they persist is that each one individually looks too small to matter.
Run it on your own product
In the order she did it — each step's output feeds the next:
- Profit margin calculator — with your labour counted in the unit cost. This is the step people skip.
- Shipping cost calculator — postage, packaging and handling against what you charge.
- Marketplace comparison — once the product is priced properly, not before.
- Discount impact — before committing to any sale.
