How this calculator works
Estimate marketplace fees, ads, refunds, shipping, packaging, and true seller profit for marketplace orders.
Example
A $100 order can look profitable until referral fees, payment fees, packaging, shipping, advertising, and refund allowance are included.
What makes this tool more practical
- Marketplace presets help you start with common fee structures, then adjust the exact percentages for your real account.
- Advertising cost and refund allowance are included because many marketplace sellers overestimate profit when they only subtract product cost and platform fees.
- The break-even sale price is useful when you need to decide whether a product can survive discounts, free shipping, or paid traffic.
When to use it
Use this tool when you need a quick business estimate before setting a price, sending a quote, planning a campaign, comparing fees, or checking whether the numbers still make sense.
Important note
Results are estimates based on the numbers you enter. They do not replace professional accounting, tax, legal, lending, or financial advice.
