About Us

Platform Fee Calculator was built with a single mission: to provide the reseller community with the fastest, most accurate, and most private tool for calculating selling costs.

Why We Built This

As sellers ourselves, we were tired of slow, ad-cluttered fee calculators that tracked every move. We wanted a tool that felt modern, respected user privacy, and stayed up-to-date with the latest platform fee structures—including the major 2026 updates.

Our Principles

• Privacy First: We don't collect your data. All calculations happen locally in your browser.
• Speed Matters: Built with Astro and Tailwind 4 for instant load times and zero-lag interactions.
• No Ads: We believe a calculator should be a clean tool, not an advertising platform.
• Accuracy: We manually verify all rates against official platform documentation.

Built for 2026

The selling landscape changed significantly in 2026. From new eBay category tiers to adjusted PayPal international rates, we ensure every calculation reflects the current reality of online selling.
