Matte Poster 18×24″ Shopify Profit Calculator

Shopify charges no marketplace commission on the Matte Poster 18×24″; 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 18×24 poster for $5.50 + $4.99 shipping, and Printify from $4.73 + $7.49; most sellers list it between $19.99 and $29.99.

At a $24.99 price with free shipping and Printful fulfillment, that's $1.02 in Shopify fees, leaving $13.48 profit per sale — a 53.9% margin, or roughly 75 sales to clear $1,000 in profit. For the Matte Poster 18×24″, Printful is the more profitable fulfiller on Shopify — about $1.73 more per sale at $24.99 (all-in cost $10.49 on Printful vs $12.22 on Printify). Breakeven — the price where profit hits $0 — is $11.11 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.
