Understanding pricing and profit margin — sensitivity table
Everyday editorial team · GEOINNOVATION CO., LTD · Published · Updated
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.
Reading the unit cost sensitivity table
The tool evaluates the same model across a range of unit cost values while holding other assumptions constant. Choose a realistic low value, high value and number of points. Each row reports the same headline measure; the table is a set of conditional calculations, not a probability distribution or a forecast. Input-step rounding can make nearby rows equal.

Sensitivity analysis: 5 comparison points
Unit cost ranges from $14 to $42.
- Unit cost: $14: 60.3%
- Unit cost: $21: 48.7%
- Unit cost: $28: 37.0%
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.
- Does the most favorable row show the most likely outcome?
- No. The table assigns no likelihood to any row. It shows how the result responds to the chosen assumption, and you remain responsible for selecting a plausible range.
