How accurate is this calculator?
Our calculator uses the latest fee structures from each platform to provide accurate estimates. However, actual fees may vary slightly based on your specific account settings, promotions, or regional differences. We recommend using this as a guide and verifying with your platform's official fee calculator for exact amounts.
Do I need to create an account to use this tool?
No, our calculator is completely free to use without any registration or sign-up required. All calculations happen in your browser, and we don't store any of your data.
How often are the fee structures updated?
We update our fee structures whenever platforms like Amazon, eBay, or Shopify announce changes. Typically, we update within 1-2 business days of any official fee changes being announced.
Can I save my calculations for future reference?
Yes! You can download your results as a PDF or Excel file, or copy the unique URL generated for each calculation to return to it later. The URL contains all your input parameters so you can share or revisit your calculations anytime.
Why are my actual platform fees different from the calculator?
