Example inputs: Use the example values shown in the calculator and replace them with one verified case from your own records.. For Marketplace Fee Comparison 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.

Do not change the Marketplace Fee Comparison Calculator formula to fit an expected answer. Recheck the input definition first when the result looks wrong. For Marketplace Fee Comparison Calculator, the output should point to a decision, a check or a follow-up calculation.
