How this is calculated

Pricing backwards from a desired margin is far safer than marking up cost and hoping. This calculator takes your fully loaded unit cost, the marketplace or platform fee, and your target net margin, and returns the selling price required to achieve it.

Real example: Pricing for 25% margin

COGS $8.40, shipping $2.10, fixed overhead $1.00/unit, platform fee 15%, payment processing 2.9%, target margin 25%.

Result: Required price $18.18 — a 116% markup on cost. Fees and margin consume 66% of the selling price, leaving 34% for costs.

Loaded cost = product cost + shipping + allocated fixed cost
Total deduction rate = platform fee + payment processing + advertising + target margin
Required price = loaded cost ÷ (1 − total deduction rate)
Markup on cost = (required price − product cost) ÷ product cost

What to make of the number

The reason this formula catches people out is that fees are a percentage of price, not of cost. Adding 15% to your cost-based price undercharges you, because the platform takes its 15% from the final number. At a 25% target margin and 26% combined fees, the required price is roughly 1.9× your loaded cost.

Frequently asked questions

Why can't I just add my margin percentage to the cost?

Because fees and ad spend are calculated on the selling price, not on cost. Adding a percentage to cost understates the price you need, and the error grows as fees rise. Working from price downwards avoids it entirely.

What target margin should I use?

It depends on the channel. Marketplace sellers with storage and returns exposure generally need 20–30%; own-store sellers with lower fee loads can work at 15–20% as long as acquisition cost is under control.

Should fixed overhead be allocated per unit?

Yes, if you want the price to actually recover your overhead. Divide expected monthly fixed costs by realistic monthly unit volume — using optimistic volume makes the allocation too small and the price too low.

What if the required price is above what the market pays?

Then the product does not work at that cost base. Your options are to reduce unit cost, reduce dimensions to drop a fulfilment tier, raise the price through bundling or positioning, or drop the product. Cutting your margin to reach a price point just defers the problem.

How does discounting affect this?

A discount comes straight off the margin, not off the cost. A 20% discount on a product priced at a 25% margin removes most of the profit on that unit, which is why discount-led growth needs a much higher starting margin.

Should I price differently across marketplaces?

Yes. Fee structures differ between Amazon, eBay, Etsy, and Shopify. A price that works on one platform may lose money on another. Run each marketplace through its own calculator.

How do I factor in currency conversion?

Currency fluctuation can erase margin overnight. Add a 2–3% buffer to your price if you source in one currency and sell in another. Track the spread monthly.

What role does psychological pricing play?

$29.99 converts better than $30.00 even though the difference is one cent. Use prices ending in .99 or .95 for marketplaces, but only if the margin model still holds at that price point.
