Measure full cost
Purchase, commission, fulfilment, returns and support: every cost must belong to its channel.
E-commerce selling price and margin calculator
Add purchase, commission, fulfilment, returns and support. Calculate profit, margin, markup and the floor price for each channel.
Per-order estimate excluding VAT: use the commission rate actually charged on the sale. VAT, customer-paid shipping and fixed costs still need a per-channel calculation.

Add a product when you need it, then review each guardrail separately.
Costs and price for the selected product
Calculate a selling price, a margin and a floor price
A price that looks profitable can already be losing money. The difference appears when operating costs are removed.
Set the guardrail
The floor price is where real margin reaches 0%. A minimum margin moves it higher.
Automate within the limit
A repricing engine can follow the market without crossing your rules.
Two ways to calculate profitability
A selling price and a margin target answer different questions. Both calculations start from the same full cost.
You already know your price
Enter the listed price. The calculator removes purchase, commission, fulfilment, returns and support, then shows the profit, margin rate and markup.
You know your target
Enter the margin or markup rate you need. The calculator works back to the selling price required to cover variable costs.
From supplier cost to selling price
Move from a spreadsheet to calculated prices on every product
The calculator checks up to 20 products. Across a catalogue, landed cost and selling price must move together when a supplier or channel changes.

1. Build landed cost
Supplier price, freight, customs and extra charges build the landed cost of every SKU.
See procurement and landed costsmyPricing
2. Set your minimum margin
A rule by channel, brand or category turns total cost into a floor price.

3. Adjust without crossing the floor
Repricing follows the market and proposes a price within the profitability limits you set.

FAQ: floor prices, margins and marketplaces
Add purchase price, fulfilment, average returns and support costs. Divide that total by one minus your marketplace commission or payment-fee rate. The result is your floor price: below it, variable costs are no longer covered.
Margin divides profit by variable costs. Markup divides the same profit by the selling price. The calculator shows both so you do not compare percentages built on different bases.
No. Enter amounts excluding VAT: collected VAT is not margin. This calculation compares your costs and selling price before tax.
Yes. Even when they do not affect every order, use their average cost per sale. Ignoring returns or fulfilment creates a theoretical margin that overstates profitability.
Yes. Run the calculation by channel: commission, fulfilment, shipping and return rate vary between Amazon, Fnac, Cdiscount and your own store. One average floor price can hide a loss-making sale.
Marketplaces often charge commission on the VAT-inclusive price and sometimes on customer-paid shipping. For this simplified VAT-exclusive calculation, use the rate seen in your statements: commission charged divided by revenue collected before VAT. That keeps the estimate coherent without recreating each channel’s fee grid.
A floor price covers your costs. A minimum margin adds the level of profitability you want to protect on every sale, even when competitors cut their prices.
Keep your price competitive. Keep your margin protected.
