About the Marketplace Fee Calculator

Marketplace Fee Calculator compares multiple selling channels using manually entered commission, payment, advertising, return-allowance, fixed, fulfillment and shipping costs.

Each channel shows total modeled deductions, effective fee percentage, contribution profit and margin from one common selling price, product cost and packaging cost.

Example channels are editable planning placeholders, not current official fees for Amazon, Flipkart, Etsy, Shopify or any other platform. Confirm rates, taxes, refund rules and category-specific charges in the current seller agreement.

Key features

  • Unlimited editable comparison channels

Frequently asked questions

Are the example fees official?
No. They are editable example values and may not match any platform, category, region or seller plan.
What is effective fee rate?
Total modeled channel deductions divided by the entered selling price.
Does the highest profit channel mean it is best?
No. The comparison excludes demand, customer quality, support workload, payment timing and other strategic factors.
Can I compare a direct store?
Yes. Enter payment, advertising, fulfillment and shipping assumptions with zero marketplace commission where appropriate.
