Calculator
The same product can look healthy on one channel and thin on another. Use this calculator to compare marketplace take-home against direct-to-consumer economics so you can see whether the store stack and acquisition burden really beat the platform.
Enter one selling price and product cost, then model the marketplace fee stack against the DTC store stack. Use the DTC ad cost field when you want to compare the order after acquisition instead of before it.
Three channel comparison scenarios.
Formula
Marketplace orders usually carry heavier fee drag and cleaner demand. DTC orders usually carry lighter checkout fees and heavier acquisition burden. This comparison is useful when you want to know which channel deserves the next unit of effort instead of just the louder revenue number.
Once the channel gap is clear, clean the marketplace path and the store path individually so the comparison rests on real fee stacks, not blended guesses.
