20oz Stainless Tumbler Shopify Profit Calculator

Shopify charges no marketplace commission on the 20oz Stainless Tumbler; the only per-sale cost is Shopify Payments at 2.9% + $0.30, so you keep more of each sale than on a marketplace — in exchange for a monthly plan that isn't in this per-sale math. Right now Printful fulfills the 20oz Stainless Tumbler for $24.97 + $4.99 shipping, and Printify from $21.79 + $6.69; most sellers list it between $24.99 and $34.99.

At a $29.99 price with free shipping and Printful fulfillment, that's $1.17 in Shopify fees, leaving -$1.14 profit per sale — a -3.8% margin, so you'd need to raise the price to turn a profit at all. For the 20oz Stainless Tumbler, Printify is the more profitable fulfiller on Shopify — about $1.48 more per sale at $29.99 (all-in cost $29.96 on Printful vs $28.48 on Printify). Breakeven — the price where profit hits $0 — is $31.16 on Printful; sell below that and you're paying to make the sale.

Remember the subscription: Shopify's lower per-sale fee only beats a marketplace once your volume covers the monthly plan, so it pays off as you scale rather than on your first few orders.
