Most pricing questions collapse into three underlying philosophies. None is universally "right" — the mistake is picking one by habit rather than by what the product and market actually support.
1. Cost-plus pricing
Set price by starting from cost and adding a target margin or markup. Formula: Price = Cost ÷ (1 − target margin), or Price = Cost × (1 + target markup). See Understanding Landed Cost, Margin, and Markup for why margin and markup aren't the same number.
Worked example: Landed cost = $8.00. Target margin = 55%. Price = $8.00 ÷ (1 − 0.55) = $8.00 ÷ 0.45 = $17.78.
Cost-plus is fast, protects margin by construction, and requires the least market research — but it ignores what customers will actually pay and what competitors charge. A cost-plus price can be needlessly low (leaving money on the table for a differentiated product) or hopelessly high (if your landed cost is worse than a competitor's).
2. Competitive pricing
Set price relative to what comparable listings already charge — at, above, or below the market, deliberately. See Competitive Pricing for the mechanics.
Competitive pricing is realistic about what buyers will actually pay in a market with visible alternatives (which most marketplace categories are), but taken alone it can walk a seller into a margin they never actually checked was profitable. Always run a competitive price through your own cost stack before committing to it — see The Full Cost Stack of a Marketplace Sale.
3. Value-based pricing
Set price based on what the product is worth to the customer — the problem it solves, the alternative cost of not having it, or genuine differentiation (quality, brand, bundled service) — rather than cost or competitor price alone.
Value-based pricing captures more margin when it's justified, but requires real proof of differentiation (reviews, brand recognition, a feature competitors lack); trying to charge a value premium without that proof usually just looks like an overpriced listing next to cheaper, equivalent-looking alternatives.
Which one should you actually use?
| Situation | Lean toward |
|---|---|
| Commodity product, many near-identical listings | Competitive, with a cost-plus floor |
| Genuinely differentiated product (patented, branded, unique) | Value-based |
| First-time pricing, no market data yet | Cost-plus, then adjust after watching competitor prices and conversion |
| Mature product, thin category, price-sensitive buyers | Competitive, watched closely |
In practice, most experienced sellers run a hybrid: calculate a cost-plus floor (the price below which the sale isn't worth making, from your Product Profitability Calculator numbers), then set the actual listed price using competitive and/or value-based judgment above that floor — never below it just because competitors are cheaper.
A pricing decision walkthrough
- Calculate landed cost and the full cost stack (fees, fulfillment, ad-spend assumption, return-rate assumption).
- Calculate the break-even price at your minimum acceptable contribution margin — this is your floor.
- Check where comparable listings are priced.
- Decide if you have a genuine differentiation story that supports pricing above the competitive median.
- Set price at or above your floor, informed by steps 3-4 — never purely at the floor unless you're intentionally running a low-price strategy.
- Revisit at least quarterly, or sooner if a cost input (freight, a marketplace fee change) shifts materially.
Mistakes
- Pricing purely off a "target markup" without ever checking what the price looks like next to real competing listings.
- Copying a competitor's price without knowing their cost structure — a competitor with a cheaper supplier, owned brand, or higher volume can profitably sustain a price that would lose you money.
- Treating a launch price as permanent instead of a hypothesis to revisit once real sales and conversion data comes in.
Checklist
- Landed cost and full fee/fulfillment stack calculated for this specific marketplace.
- Break-even/floor price calculated at your minimum acceptable contribution margin.
- Reviewed at least 5-10 comparable listings' current pricing.
- Decided explicitly which of the three approaches (or hybrid) you're using, and why.
- Calendar reminder set to revisit pricing at least quarterly.
