UK VAT Calculator FAQ
What is the standard VAT rate in the UK?
The standard UK VAT rate is 20%. A net amount of £100 becomes £120 including VAT, and the VAT portion is £20.
What other UK VAT rates are commonly used?
The UK also commonly uses a 5% reduced rate and a 0% zero rate for qualifying goods and services. The correct rate depends on what is being sold and the applicable VAT rules.
How do I remove 20% UK VAT from a gross price?
Divide the gross amount by 1.20 to get the net amount. The VAT is the difference between the gross amount and the net amount.
Can I use this calculator for UK invoices?
Yes. Advanced mode supports multiple invoice rows, different VAT rates, totals by rate, rounding choices, and CSV export, which is useful for invoice preparation and checking.
When should I use reverse charge mode?
Use reverse charge mode only when the transaction falls under a reverse-charge VAT treatment. For ordinary UK domestic consumer pricing and most standard invoices, the normal B2C mode is the appropriate choice.
