How to use this tool well

Use this Marketplace Fee Comparison Calculator as a quick decision aid, not as a one-time checkbox. Start with conservative inputs, then run a second pass with optimistic and pessimistic assumptions so you can see which variable actually changes the outcome.

A useful workflow is:

1. Enter your current baseline numbers.
2. Change one input at a time so the output stays explainable.
3. Save the result before you compare vendors, channels, or operating plans.
4. Recheck the numbers after real data comes in.

What to watch before acting

The biggest mistake is treating the output as precise when the inputs are guesses. Fees, shipping, returns, conversion rate, timing, and workload can all move the final result. If one assumption changes the answer dramatically, that is the number to validate first.
