"Estimated Profit" is a cash figure — total cash fees actually paid, before any VAT recovery. "Estimated economic fees" above nets off potentially reclaimable VAT instead. See methodology.

These results are an estimate based on the transaction details and settings you entered — not a quote, invoice or guarantee. Marketplace fees, thresholds, promotions, VAT treatment and other policies can change at any time. A fee that is variable, unknown or not yet verified is disclosed above as an assumption or exclusion — it is never silently treated as £0. Before making a material decision, verify the relevant marketplace’s current terms and, where appropriate, speak to a qualified adviser. EasyFeezy does not provide personal tax, accounting, financial or legal advice.

What's included

  • 52 selectable categories, every one individually confirmed — 9 given directly in this build's specification, 43 confirmed during a follow-up audit pass.
  • No category is left as an unverified, automatically-pulled figure — none require a manual rate.
  • VAT is applied to the Individual/Professional plan fees (explicitly ex-VAT); VAT on referral fees is not calculated, since it couldn't be confirmed, and is disclosed rather than guessed.
