30% margin pricing formula
Required price = non-percentage order costs ÷ (1 − percentage fees − target margin).
Use percentage fees as decimals. For example, use 0.08 for 8% percentage fees and 0.30 for a 30% target margin.

Use this table for a fast planning check. Each cost amount should include every fixed per-order cost. Percentage fees are applied to the selling price.
| Fixed order costs | 0% percentage fees | 5% percentage fees | 10% percentage fees |
|---|---|---|---|
| $10 | $14.29 | $15.38 | $16.67 |
| $20 | $28.57 | $30.77 | $33.33 |
| $30 | $42.86 | $46.15 | $50.00 |
| $40 | $57.14 | $61.54 | $66.67 |
Formula used: costs ÷ (1 − fee rate − 0.30). Round the final price only after calculating with unrounded inputs.
Worked example
Assume a seller has $24 in non-percentage costs for one order: product, packaging, seller-paid shipping, fixed fee components, and allocated overhead. The seller expects 8% percentage fees and wants a 30% margin.
| Step | Calculation | Result |
|---|---|---|
| Set the denominator | 1 − 0.08 − 0.30 | 0.62 |
| Calculate planning price | $24 ÷ 0.62 | $38.71 |
| Estimated percentage fees | $38.71 × 8% | $3.10 |
| Estimated profit | $38.71 − $24 − $3.10 | $11.61 |
| Estimated margin | $11.61 ÷ $38.71 | 30% |
Costs sellers often miss
- Platform and payment fees, including fixed per-order components
- Packaging, labels, fulfillment labor, and seller-paid shipping
- Returns, replacements, refunds, and customer service time
- Advertising, affiliate commissions, and promotional discounts
- Monthly software, plan, and overhead allocation
Check the price before using it
A formula creates a planning price, not a market-tested price. Compare the output with competitor positioning, expected conversion, inventory turnover, and customer willingness to pay. If the price is not viable, change the cost structure, target margin, bundle size, channel, or offer rather than hiding costs from the calculation.
30% margin is not a 30% markup
With $24 of costs and no percentage fee, adding a 30% markup produces a $31.20 price and only a 23.08% margin. A true 30% margin requires $34.29 before percentage fees. This distinction matters because using markup when you mean margin systematically underprices the product.
Verify the fee inputs
Use your own invoices, payout statements, and current platform terms for every input. For common US fee assumptions, review the dated rate and source ledger before relying on a planning price.
Frequently asked questions
Is a 30% profit margin good?
It depends on category, lifecycle, return rate, customer-acquisition cost, working-capital needs, and business goals. Use a target that leaves a buffer for uncertainty.
Should advertising be included in a target price?
Include expected acquisition cost when advertising is required to obtain the order. If it changes by campaign or channel, test a range of scenarios.
Is margin the same as markup?
No. Margin divides profit by revenue, while markup divides profit by cost. Before fee interactions, a 30% margin corresponds to about a 42.86% markup on cost, not a 30% markup.
