Calculators
Work the number out on the page, then take the Excel version away.
Start hereeBay Fee CalculatorFinal value fee, the per-order fee, the regulatory fee and promoted listings, down to what actually stays with you. eBay charges VAT on its fees, so the same headline rate costs a registered seller a sixth less than an unregistered one.All four eBay fees, gross and net of the VAT you reclaimWhy free postage is not free, demonstrated rather than assertedFifteen listings ranked by what each one actually leavesCalculator plus Excel
VAT Margin Scheme CalculatorVAT on your margin instead of the whole price. The saving is the VAT fraction of what you paid, whatever you sell it for.Calculator plus Excel
Break-Even Promoted Listings RateThe ad rate above which a listing stops paying, and the extra sales the promotion has to bring in before it has covered the ones you had anyway.Calculator plus Excel
Am I Trading? CheckerSix questions on HMRC's badges of trade, and a straight answer about whether your selling is a hobby or a business.Checker
VAT CalculatorAdd it, take it off, and see the fraction behind both. The one everybody needs and nobody bookmarks.Calculator
VAT Threshold TrackerWhere you stand against the £90,000 rolling threshold, measured on the twelve months that actually count.Calculator plus Excel
Profit Margin CalculatorMarkup and margin are different numbers and confusing them is how sellers price themselves out of a profit.Calculator
Workbooks and trackers
Excel files that keep working after you close the tab.
