Three lines on that receipt do most of the damage.

Throwing, trimming, glazing35 min at $18/hr−10.50

The biggest line is the one nobody writes down.

Thirty-five minutes of work sits inside every mug. At a modest $18 an hour, that's $10.50, the single largest cost in the piece. A price that skips it pays the maker $0 an hour.

Box, tissue, label−1.75

Packaging leaves with every order.

$1.75 of box, tissue, and label ships out each time. At 50 orders a month, that's $87.50 of costs that rarely appear in a price.

Shopify + Stripe2.9% + 30¢−0.94

The fee is charged before the clay is paid for.

Shopify and Stripe take 2.9% plus 30¢ of every sale. On this mug, 94¢, deducted the moment the order comes in.
