THE THINKING BEHIND THE NUMBER
How to use this calculator
Compare selling-channel economics with the same product price and costs. Marketplace fee structures differ by category and programme, so enter your actual seller fees rather than relying on universal rates.
A practical example
Compare the same product selling price on your Shopify store and one marketplace. Add your actual seller fees, fulfilment, acquisition and return costs for each channel. Switch between per-order and monthly contribution without assuming one channel always wins.
How to read your result
This comparison is an estimate, not a channel recommendation. Tax withholding affects settlement cash flow but is not automatically treated as a permanent profit expense.
Use the result alongside your store analytics, product costs and operating context. If the inputs are estimates, treat the output as an estimate too. Change one input at a time to understand what drives the result.
