FBA True Profit Calculator uses Units sold, Selling price per unit, Product cost per unit, FBA/marketplace fees (%), Shipping per unit, Advertising spend, Other costs. Treat each value as part of a definition, not just a box to fill. The period, unit and source should match the question you are trying to answer.
Units sold: Treat “Units sold” as a defined input for FBA True Profit Calculator. Check where the figure came from before using it in a second scenario.
Selling price per unit: Use the price definition that matches the result (list price, net price, invoice price or another stated basis).
Product cost per unit: Treat “Product cost per unit” as a defined input for FBA True Profit Calculator. Check where the figure came from before using it in a second scenario.
FBA/marketplace fees (%): Treat “FBA/marketplace fees (%)” as a defined input for FBA True Profit Calculator. Check where the figure came from before using it in a second scenario.

- Record the source or assumption that could materially change the FBA True Profit Calculator result.
Formula and calculation logic
Seller profit = revenue − product cost − fees − shipping − ads − other costs. The formula behind FBA True Profit Calculator is shown so the relationship between its inputs and output is clear. That is useful for review when the result later appears in a quote, budget or operating report.
For FBA True Profit Calculator, formula alone does not settle definition questions. Timing, exclusions, attribution rules and technical or accounting requirements can change what belongs in an input.
Worked example
Example inputs: Use the example values shown in the calculator and replace them with one verified case from your own records.. For FBA True Profit Calculator, change one meaningful assumption and run the calculation again. The comparison is more useful than changing several numbers at once because you can see which variable moved the output.
What to do with the result
If one FBA True Profit Calculator input is uncertain, test that assumption separately rather than presenting the final figure as more precise than the data allows. For FBA True Profit Calculator, the output should point to a decision, a check or a follow-up calculation. It should not become a number that is copied into another document without its definition.
