What this diagnostic helps you decide
Best for
Owners comparing a channel after fees and channel-specific costs.
Outputs
Fees, contribution, channel profit and channel margin.
Start here
Include channel COGS, percentage fees, variable costs and fixed costs once each.
Use a different tool when: Do not use this to identify which operating-cost layer changes profit after gross profit; use Gross to Operating Profit Bridge for that decision. Use this tool to diagnose channel profitability after all channel costs.

Channel Profitability: fees
Channel profit shows what remains after channel COGS, percentage fees, other variable costs and channel-specific fixed costs.
Formula summary
- Primary formula
- channel profit = revenue − COGS − fees − variable costs − fixed costs
Data used here
- The estimate uses your inputs and the general business formula documented in the methodology.
Decision checks
Stress-test the decision
Retest channel fee rate as a percentage of channel revenue and channel fixed costs in currency units per period, ex tax.
When this estimate can be misleading
- Results depend on complete, consistently classified inputs.
- Demand, timing, quality and strategic fit remain separate decisions.
- This is educational business decision support, not accounting, tax, legal or financial advice.
- Channel profit shows what remains after channel COGS, percentage fees, other variable costs and channel-specific fixed costs.

Frequently asked questions
How do I diagnose channel profitability after all channel costs?
Use channel profit and channel profit margin to continue, reprice or exit the channel on the entered cost basis.
What should I investigate after the diagnostic?
Use the diagnostic to identify which record or operating driver needs investigation; it does not establish the cause by itself.
