Etsy and Amazon can add 20% UK VAT on seller fees. If you're not VAT-registered, that fee VAT is usually a cost you cannot reclaim, and many generic spreadsheets do not show it separately. Estimate the fee-VAT cost on one product for free, then use the Studio to model what the £90,000 VAT registration threshold could do to your take-home before it becomes urgent.
Generic calculators and old spreadsheets can feel "good enough" until they skip the fee lines that affect pricing. Two of them matter most for growing marketplace sellers.
Etsy and Amazon can charge 20% UK VAT on seller fees. Not VAT-registered? That fee VAT is usually a cost you cannot get back. Pennies per order can become hundreds a year, and a spreadsheet that ignores it can overstate margin.
Go over £90,000 of VAT-taxable turnover and you must register for VAT. That can change how your marketplace prices, output VAT and input VAT interact. Sellers who model it early can review price rises before the effective registration date.
Transaction fee, payment processing, regulatory fee, Offsite Ads, listing fees — each can sit on a different base. One wrong base can move margin enough to affect pricing, especially on lower-price products.
You set a price, hope it clears, and review it months later. Working backwards from a target margin after fees, fee VAT and costs is tedious by hand, so many sellers do not keep the model current.
No email, no signup, no upload. Type in one product's price and costs and the free check estimates your net profit and seller-fee VAT under editable default assumptions. It runs entirely in your browser; your numbers never leave your device.
A planning aid, not tax advice. Want the £90k threshold simulator and a reviewable breakdown across your catalogue? That's the £29 Studio below.
The free single-product check reveals what one product may be losing. The paid Studio is for the two decisions that actually move money — modelling the £90k threshold and producing a reviewable breakdown — across your catalogue. Every figure is documented, editable and checkable against your own fee statement.
Models the same sale as not-registered vs registered: the profit change under the rates you enter, the output VAT separated from revenue, and the fee VAT you may start reclaiming. Review price rises before you cross £90k.
Export any scenario — every fee line, the VAT-on-fees treatment, output VAT and net profit — to a clean CSV you can review with your accountant. Plus a blank tracking template and a plain-English guide showing how each figure is calculated.
Per-order profit and margin for Etsy or Amazon, every fee line shown, with 20% UK VAT on seller fees treated as a cost if you are not VAT-registered, or netted out as potentially reclaimable input VAT if you are registered.
Solves for your break-even price and a target-margin price using the rates and costs you enter. Includes editable, dated rate defaults you match to your category and country.
Run three of your real products through the Studio. If it does not make your marketplace-fee VAT or £90k threshold decision clearer than it is today, email us within 30 days for a full, no-questions refund, and keep the guide and CSV template.
No. It's a planning and pricing aid that does the fee and VAT maths for you. It doesn't file your VAT return and it doesn't replace an accountant. The fee rates are clearly-labelled, editable defaults you should confirm against your own Etsy/Amazon statement and current HMRC rates.
Every rate is editable, so you can update it yourself in seconds and match your own category and country. We also refresh the built-in defaults when fees change, free — no subscription needed.
No. The whole tool runs in your browser on your own device. There's no account, no login and no tracking — you can even use it offline. Your numbers never leave your computer.
Often, yes. If you are not VAT-registered, VAT charged on marketplace seller fees is usually a cost you cannot reclaim. This tool shows that line separately instead of burying it in a fee total.
It can model a different sale-VAT rate, but it is not a cross-border VAT compliance engine. For digital goods and overseas buyers, check the marketplace rules and GOV.UK guidance before relying on a scenario.
One-time. You pay once and it's yours, including free rate updates. There's an optional £9/year "always-current" tier if you want new tools as they ship, but it's never required.
Separate marketplace fee VAT, model target prices, and compare the same sale before and after VAT registration using assumptions you can check.
