About Fee Calculator Pro
Fee Calculator Pro is a free, independent tool built for online sellers, gig workers, real estate professionals, and anyone who needs accurate, up-to-date fee estimates before making financial decisions. We cover over 30 platforms — from eBay and PayPal to USCIS immigration fees and DMV registration costs.
Our Mission
Hidden fees cost people real money. Our mission is simple: give everyone access to accurate, transparent fee calculations — for free — so you always know your true costs before you list, transfer, file, or sell.
How We Maintain Accuracy
Every calculator on Fee Calculator Pro is built directly from official platform fee schedules, government rate tables, and published regulatory documents. We monitor fee changes continuously and update our calculators whenever a platform announces new rates. Each calculator page displays a “Last Verified” date so you always know how current the data is.
Our primary sources include:
- Official platform seller centres and fee pages (eBay, Etsy, PayPal, Stripe, Square, etc.)
- U.S. Customs and Immigration Services (USCIS) official fee schedules
- State DMV websites and vehicle registration rate tables
- IRS publications for gig economy and self-employment tax rates
- HM Land Registry fee order (England and Wales)
- State revenue department publications for transfer and estate taxes
Who We Are
Fee Calculator Pro is operated by a small team of finance-focused developers and researchers based in the United States. Our team has backgrounds in e-commerce, tax preparation, and financial software development. We are not affiliated with any of the platforms our calculators cover — our goal is to provide objective, unbiased fee information.

The calculators and guides on Fee Calculator Pro are provided for informational and estimation purposes only. They are not a substitute for professional financial, tax, or legal advice. For decisions involving significant sums — such as estate planning, immigration filings, or large real estate transactions — we strongly recommend consulting a qualified professional.
