About SellerCalc

SellerCalc is a free hub of calculators for online sellers — built specifically for Shopify, Etsy, Daraz Pakistan, and TikTok Shop. We make it fast to answer the only question that matters: am I actually making money on this product?

Who we are

SellerCalc was built by a small team of ecommerce operators who got tired of recreating the same spreadsheets every time a marketplace changed its fees. We're independent — not affiliated with Shopify, Etsy, Daraz, or TikTok — and we pay our bills through display ads, not data harvesting.

How we keep formulas current

Marketplace fees change every year. We review every calculator at least once per quarter against the platform's published fee schedule, and immediately when a major change is announced. Each calculator shows the last update date at the bottom of the page.

Our commitment

• Always free, no signup, no paywalled features.
• No data collection beyond standard anonymous analytics.
• Formulas published in plain English on our methodology page.
• Updates within 14 days of any platform fee change.
