Cost-Plus Pricing: When It’s Enough and When It Isn’t

Cost-plus means: take what the unit cost you, add a percentage, print a price. It is fast, easy to teach a new hire, and good enough for a first shelf tag. It is not a full pricing strategy — and treating it like one is how shops get surprised by fees and rent.

A clean example

Wholesale jar costs \$6. You add 100% (keystone). Shelf price = \$12. Cash sale, no card fee, no marketplace: you keep \$6 before overhead. That is cost-plus doing its job.

When it is enough

Stable wholesale cost, low fee drag (cash or simple card), and a category where peers already sit near the same multiple. Gift shops, small makers selling in person, and short trials of a new SKU often start here without apology.

When it breaks

Same \$6 jar on Etsy at \$12. Listing, transaction, and processing can take a few dollars off the top depending on your fee stack — enough that your “100% markup” is no longer anything like a 50% margin after fees. Ads and returns widen the hole. If contribution after variable cost cannot cover rent at a volume you can actually sell, another turn of cost-plus will not fix the month.

Markup language vs margin language

“Add 50%” is ambiguous. Some owners mean markup on cost; others mean they want a 50% margin on price. Those are different stickers. The cost-plus pricing calculator lets you choose either so the number matches what you meant.

A practical sequence

1) Draft a price with cost-plus or the markup calculator. 2) Run the fee tool that matches how you sell (Etsy, Shopify, FBA, or none). 3) Put fixed costs into break-even and see if the volume is believable. Adjust once. Do not stack three optimistic markups and call it planning.

What this skips

Demand curves, brand positioning, and competitor maps. Cost-plus answers “what sticker from this cost?” — not “will anyone buy it.” Estimates only; not accounting advice.
