How the numbers are made

Methodology

Every fee our calculator returns is modeled directly from eBay's own published fee schedule — not from third-party summaries. This page shows exactly where the numbers come from, how often we re-check them, one calculation worked end to end, and where an estimate stops and your real invoice begins.

The sources we model

The eBay fee engine encodes the full per-category tier structure, the $0.30/$0.40 per-order fee, Store rates, and the documented surcharges and discounts. Those values are transcribed from these primary pages:

• eBay — Selling fees (standard, no Store)

  Final value fee percentages and per-order fee by category.

• eBay — Store selling fees

  Reduced final value fee rates for Basic Store subscriptions and higher.

• eBay — Managed payments seller fees

  How fees are deducted from the buyer's payment before payout.

Verification cadence

• We re-check the source pages above on a scheduled cadence and whenever eBay announces a fee change, then reconcile them against documented invoice line items.
• When a rate changes, we edit a single data file (the fee engine) and bump the "fees verified" date. The calculator and every on-page fee table read from that one file, so they update together and never drift apart.
• The current verification date is shown on the calculator and in every guide footer. Fees were last verified June 5, 2026.

One calculation, worked

Take a $40 item with $6 shipping in a most-categories listing, standard seller, no Store subscription:

Change any input in the calculator and the same stack re-runs live, with every surcharge and discount wired in. For the step-by-step version, see how eBay fees work.

Limitations

A calculator models the published schedule; it does not see your account. These estimates can differ from your actual invoice because of:

• Account-specific rates, promotional credits, coupons, or fee waivers eBay applies to your account.
• Dispute outcomes, refunds, and partial refunds, which change fees after a sale.
• Fee changes announced between our last verification date and your sale, and regional differences outside the US managed-payments model we cover.
• Optional costs you opt into — Promoted Listings ad rates and shipping labels — which we include only when you enter them.

Bottom line: use FlipFees to plan and price, then confirm the final number against your actual eBay invoice. Spot a fee that looks off? Tell us on the contact page — corrections are how the data stays trustworthy.
