What this calculation is for
A product-margin calculation distinguishes the markup on cost from the portion of selling price left after costs. Payment fees and fulfillment can make a seemingly generous markup leave little operating contribution.
How the method works
Selling price minus product cost, percentage selling fees and fulfillment gives unit contribution. Dividing by price gives margin; the target-price equation also accounts for the fee percentage. The displayed model uses: Net contribution = price − cost − selling fees − fulfillment; margin is contribution ÷ price.
A worked example
For an illustrative pricing and profit margin scenario, use Unit cost: 28 $; Selling price: 60 $; Payment and marketplace fee: 8 %; Shipping and fulfillment per unit: 5 $; Target net margin: 25 %; Units sold per month: 250 units. The modeled net contribution margin is 37.0%. These are example assumptions, not current prices, official benefit amounts or personalized advice.
Assumptions and real-world differences
Contribution is not net profit after all overhead. Returns, tax, advertising, fixed expenses and fee minimums may be missing. Some target-margin and fee combinations cannot produce a finite profitable price. Fees and costs are entered by user; taxes, refunds, overhead and channel-specific rules may change profit.
Using the pricing and profit margin estimate
Start with the assumptions that match your situation, then read the headline together with the detailed breakdown. This tool’s baseline calculation uses unit cost, selling price, payment and marketplace fee, shipping and fulfillment per unit, target net margin, units sold per month. Changing an input changes only the modeled consequences of that input; it does not retrieve a quote or validate your eligibility.
Reproduce this tool’s example
These fixed example inputs are independent of edits you make above. Enter them in this tool to reproduce the result, then replace them with your own assumptions.
- Unit cost
- 28 $
- Selling price
- 60 $
- Payment and marketplace fee
- 8 %
- Shipping and fulfillment per unit
- 5 $
- Target net margin
- 25 %
- Units sold per month
- 250 units
Net contribution margin: 37.0%
$22.2 per unit after entered costs.
- Selling price: $60
- Unit cost: $28
- Fees and shipping: $9.8
Frequently asked questions
- Is a 50% markup a 50% margin?
- No. A $10 cost sold for $15 has 50% markup but only about 33.3% margin before other costs.
- Which inputs should I check before using this pricing and profit margin estimate?
- Check unit cost, selling price, payment and marketplace fee, shipping and fulfillment per unit, target net margin, units sold per month. Match each field’s unit and time period, then compare the detailed rows rather than treating the headline alone as the complete answer.
- Do the example defaults represent a recommended plan?
- No. Defaults make the method inspectable. Replace them with relevant assumptions and test a less favorable case before making a decision.
