About CalcFees

Who we are

CalcFees is maintained by a team of international accountants and legal professionals who spend their working hours managing bookkeeping and compliance for e-commerce businesses across multiple platforms. The fee questions that sellers ask on Reddit and in forums every day are the exact same questions our clients bring to us in meetings -- and we got tired of answering them one conversation at a time. These calculators are the spreadsheets we already had, rebuilt as free tools so anyone can run the numbers without hiring us first.

Why we stay anonymous

We get asked this constantly. Short version: every client engagement comes with a non-disclosure agreement, and those NDAs cover the people doing the work, not just the data.

One client's legal team flagged the overlap between our advisory work and a public-facing tool, which killed the idea of putting names on the site. We picked anonymous and useful over credited and dead.

Every fee on this site still comes from the same official sources we cite in client reports -- that is the part we stake our professional work on.

How we verify fees

Every fee on this site comes directly from the platform's own pricing page -- PayPal's merchant fees page, Stripe's published rate card, Etsy's seller handbook, eBay's fee schedule, and so on. We link to the official source on every calculator and stamp the verification date at the top, because we have seen client invoices come in wrong when someone relied on an outdated rate from a third-party blog. When Depop dropped their entire 10% selling commission in January 2024, we had the calculator updated within two days, and we treat every fee change the same way -- verify against the source, update the math, and push it live.

How we stay updated

Payment platforms change their fee structures more often than most sellers realize -- Etsy bumped their transaction fee from 5% to 6.5%, PayPal restructured their entire rate card, and Depop eliminated their selling commission altogether in the space of roughly two years. We monitor official announcements from every platform we cover and cross-check against NerdWallet's published comparisons before updating any numbers. The goal is to never be the calculator that costs someone money because it was showing a rate that expired three months ago.

Editorial standards

We caught a wrong eBay rate on a competing calculator last year that would have cost a high-volume seller roughly $400 per month. That is why we run the same two-person review process we use on client invoices.

One team member pulls the rate from the official pricing page, a second with professional accounting experience checks it independently. Nothing goes live until both numbers match. Rate changes get confirmed and updated within 48 hours.

Your privacy

All calculations happen in your browser. Your numbers never leave your device. We do not collect your sale prices, do not require signups, and do not store your calculations. The only tracking on this site is anonymous analytics to understand which calculators people use most.

Independence

CalcFees is not affiliated with PayPal, Stripe, Etsy, eBay, Amazon, Shopify, Square, or any other platform listed on this site. Our calculators are independent and unbiased. We do not receive commissions or referral fees from any platform -- the same independence we maintain in our professional advisory work.
