Matte Poster 18×24″ Your own site Profit Calculator

Sold from your own store, the Matte Poster 18×24″ carries no marketplace or listing fee at all — just card processing at 2.9% + $0.30 — so it's the highest-margin channel here, provided you bring your own traffic. 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 Your own site 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 Your own site — 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.

The catch is traffic: your own store has no built-in audience, so budget for ads or content — the margin you save on fees often goes back into acquiring customers.
