About Profivexa

What Profivexa is

Profivexa helps sellers quickly estimate marketplace fees, profit, pricing, margin, ROAS, ACOS, break-even points and unit economics. The tools are designed to make everyday selling decisions easier to understand.

Who it is for

• Amazon sellers
• Etsy sellers
• eBay sellers
• Shopify merchants
• DTC and independent ecommerce sellers

Why Profivexa exists

Sellers need clear, quick and transparent calculators—not a complicated spreadsheet or an account before they can start. Profivexa keeps the important inputs and results visible, so you can explore a decision when you need it.

How calculations work

Calculators use the values you enter. Where relevant, marketplace tools use maintained fee rules to help form an estimate. Results are estimates only: fee policies can change, and important decisions should be checked against the relevant marketplace's public sources.

Free to use

Independence

Profivexa is not affiliated with Amazon, Etsy, eBay or Shopify. Their names and marks belong to their respective owners.

Accuracy and transparency

We aim to keep marketplace fee logic clear and review fee data against public sources. We present the assumptions used by each calculator so you can assess whether they fit your situation.
