Formula Used

Net result = revenue - product cost - platform fees - payment fees - shipping - discounts - taxes. Margin = net result ÷ revenue × 100.

Example Calculation

For example, if you sell an item for $50, pay $22 for the product, $6 in shipping, and $5 in combined fees, the estimated profit is $17 and the margin is 34%.

How to Interpret the Result

The result should answer the user’s main question immediately. After that, explain what the number means in plain language.

If the result is a cost, show whether it is before or after taxes, fees, shipping, labor, or other adjustments.
If the result is a percentage, explain what the numerator and denominator represent.
If the result is a payment, show the payment period and total amount where relevant.
If the result is a quantity, show whether the user should round up to a practical purchase amount.
If the result is an estimate, clearly state the assumptions.

Tips to Improve the Result

Include every cost, not just the marketplace fee.
Test a low-margin and a high-margin scenario before choosing a price.
Use the result with the product pricing and profit margin calculators before publishing a listing.

Common Mistakes to Avoid

Mixing units, such as inches with feet, months with years, or pre-tax with post-tax values.
Leaving out hidden costs that change the real result.
Treating an estimate as a guaranteed outcome.
Comparing two results that use different assumptions.
Forgetting to round quantities up when a real-world purchase requires whole units.
