Start From the Margin You Need

Set the margin requirement before choosing a price. Gross margin asks how much of the selling price remains after product cost. Contribution margin goes further: it measures what remains after the variable costs relevant to the decision, such as advertising. Use gross margin to assess the product’s core economics; use contribution margin to judge whether selling it through a particular channel or campaign is worthwhile.

Work backward with: price = relevant cost ÷ (1 − target margin). If the relevant cost is $30 and the target gross margin is 60%, the price is $30 ÷ 0.40 = $75. The resulting gross profit is $45, or 60% of the $75 price. For a contribution target, use the cost base that includes the variable selling costs you want the price to cover.

Do not substitute markup for margin. Markup divides profit by cost, while margin divides profit by selling price. A $30 cost and $75 price produce a 150% markup but a 60% margin. Use margin when evaluating profitability and setting financial guardrails; use markup when applying a cost-plus rule or comparing price multiples. The product pricing calculator can show both views.

Build the Cost Before You Set the Price

Build a per-unit cost sheet before choosing the retail price. Start with product cost, inbound freight, duties, and packaging. Allocate shared freight and duty by a defensible basis, such as units, weight, or customs value, and document the assumption. For imported goods, check the current treatment rather than assuming a small shipment is duty-free: the White House states that, effective August 29, 2025, imported goods sent by means other than the international postal network, valued at or under $800 and otherwise eligible for de minimis, are subject to all applicable duties (Source: The White House).

Add variable selling costs. Payment fees should be calculated from the amount actually collected, including the effect of discounts. Model the expected discount per order rather than pricing from the full-ticket amount. Returns may require reverse shipping, inspection, repacking, refund processing, and a markdown or write-off if the item cannot be resold. Include acquisition cost when judging paid growth: a $20 customer-acquisition cost is relevant to contribution from that order, but should not automatically be loaded into every SKU if some sales are organic.

Keep rent, salaried payroll, software, and other overhead in a separate operating view unless you have a clear allocation purpose. Loading all overhead into every product can hide which items work before fixed costs. Use the product pricing calculator to test the cost stack, then compare it with ORVX reporting on delivered revenue, returns, and contribution after advertising.

Worked example with sample numbers

This example uses sample numbers for a women's fashion store selling in the US. They are made up to show the method, they are not a benchmark, and your own figures will differ.

Formula: Net price needed = (variable costs + fixed fee) / (1 - target margin - percentage fee).

Sample numbers: price needed for each target margin

Showing the Price in the US

A US store may display a tax-exclusive price, such as “$80 plus applicable sales tax,” then calculate and add tax at checkout. It may instead show a tax-inclusive price and make clear that tax is already included. Neither treatment is universal: your choice can depend on state rules, customer expectations, channel requirements and whether your checkout can calculate the correct state and local rate. Do not add tax a second time to an inclusive price.

State and local obligations depend on where you have sales-tax nexus, whether you must register, the product’s taxability, and any marketplace or filing rules that apply. In South Dakota v. Wayfair, decided June 21, 2018, the Supreme Court upheld a law covering sellers that deliver more than $100,000 of goods or services into the state each year or make 200 or more separate transactions, and overruled the physical presence rule (Cornell Legal Information Institute). That decision does not make one collection method universal across the US; confirm each state and relevant local requirement with a qualified tax adviser (Source: Legal Information Institute, Cornell Law School).

Sales tax collected from the customer is generally money held for the applicable tax authority, not product revenue. Keep it separate from the price used for gross-margin and contribution analysis. ORVX’s realized-revenue reporting can help you assess delivered-order economics, while your tax records should track what was collected and what is owed.

Read the Worked Pricing Example Correctly

Read the worked example as a chain of assumptions, not as a recommended market price. The input cost is the per-unit cost already assembled for the garment: use that figure before margin, discount, or tax. The target margin then determines the required net selling revenue. If the example assumes a discount, the displayed price must be high enough that the discounted amount still delivers that target margin; do not apply the margin to the full ticket price and ignore the reduction.

Check tax separately. Where the example treats the price as tax-exclusive, the calculated result is the amount the store keeps before sales tax, and tax is added at checkout. Where it treats the price as tax-inclusive, the customer-facing total includes tax, so the tax portion must be separated before checking margin. The resulting customer price is therefore the example’s final displayed or checkout amount after applying its discount assumption and tax treatment, not simply cost divided by the margin percentage. You can test the same inputs in the free pricing calculator.

When a Higher Price Is the Wrong Move

A higher price improves unit margin only if enough units still sell. For illustration only, at $80 with $30 product cost, five orders produce $250 gross profit. At $90, four orders produce $240. The higher price raises margin per unit but reduces total profit because conversion fell from 5% to 4% on 100 visits.

Use contribution profit, not price margin alone, to judge the change. Include advertising, payment costs, discounts and refunds, then check sell-through and remaining stock. A higher price may be reasonable for a proven, scarce style; it is riskier for seasonal inventory, where slower sell-through can leave cash tied up and increase markdown exposure.

Reducing product or fulfilment cost is usually more useful when demand is strong but economics are weak. Limiting discounts helps when full-price orders already convert. Changing the offer, such as a bundle, improved fabrication, or clearer value communication, can be preferable when customers do not perceive enough value at the proposed price. Accept a lower margin when clearing aged stock recovers more cash than holding it for a higher theoretical margin.

ORVX compares product and collection contribution after advertising with delivered revenue, return rates, refund value, dead stock and remaining stock value. It can identify where a price experiment is worth running, but it cannot estimate price elasticity or predict how demand will respond.
