- Flat Rate Category %
Calculation method and formula
The tool's registered calculation explanation is:
Standard Scheme: 20% Output VAT collected minus Input VAT reclaimed on stock/fees. Flat Rate Scheme: Pay fixed % on gross turnover without reclaiming input VAT.
The result depends on the values you enter and the assumptions built into the tool. Where marketplace fees, carrier prices or tax rules apply, confirm the latest official figures before relying on the estimate.
Practical tips before you use the result
- Use current figures from your Seller Central reports, supplier quotation, invoice or other primary records.
- Keep the units consistent. Do not mix inches with centimetres, kilograms with pounds, or one currency with another.
- Test more than one realistic scenario when comparing prices, costs or campaign settings.
- Save or record the result you need before closing or refreshing the page.
- Be aware of HMRC's 'Limited Cost Trader' rules: if your relevant goods expenditure is below 2% of turnover, your Flat Rate VAT percentage jumps to 16.5%.
- Non-UK established sellers holding FBA inventory in the UK cannot use the Flat Rate Scheme and must register for standard 20% VAT immediately.
Use this tool for preliminary planning only. Tax thresholds, rates, filing duties and eligibility depend on jurisdiction and current rules. Verify figures with the relevant authority or a qualified tax professional.
Worked example: UK 20% VAT Calculator
Sample inputs:
- Annual Amazon UK Sales (£): £120000.00
- Annual UK Inventory COGS (£): £42000.00
- Flat Rate Category %: 7.5
Calculation:
- Standard Scheme Output VAT = £120,000 × 20% = £24,000.00
- Standard Scheme Input VAT reclaim = £42,000 × 20% = £8,400.00
- Standard Scheme Net VAT payable = £24,000.00 - £8,400.00 = £15,600.00
- Gross VAT-inclusive turnover base = £120,000 × 1.20 = £144,000.00
- Flat Rate Scheme VAT payable (7.5% of gross turnover) = £144,000.00 × 7.5% = £10,800.00
- Flat Rate Scheme financial advantage = £15,600.00 - £10,800.00 = £4,800.00
Result: Optimal Scheme: Flat Rate Scheme Preferred, Standard VAT: £15600.00, Flat Rate VAT: £10800.00, Advantage: £4800.00, Note: Flat rate applied to VAT-inclusive turnover, per HMRC Flat Rate Scheme rules.
Under HMRC Flat Rate Scheme rules, applying 7.5% to VAT-inclusive turnover yields £10,800 in VAT liability compared to £15,600 under Standard Scheme, providing a £4,800 annual tax savings.
