United Kingdom Calculator FAQs

How is UK VAT calculated?

Standard VAT is 20% added to the net price. To add VAT, multiply by 1.20. To find VAT in a VAT-inclusive price, divide by 6 (since VAT is 1/6 of the gross). A £120 VAT-inclusive item contains £20 VAT.

How much is stamp duty on a £400,000 house?

For a main residence purchase in England 2026, SDLT on £400,000 is approximately £7,500 (0% on the first £250,000, 5% on the next £150,000). First-time buyers pay £0 up to £425,000.

What is the difference between SDLT and LBTT?

SDLT applies to property purchases in England and Northern Ireland. LBTT applies in Scotland and uses different bands and rates. Wales uses Land Transaction Tax (LTT). All three are progressive band-based.

When does the reduced 5% VAT rate apply?

The 5% reduced rate applies to domestic energy (gas, electricity, heating fuel), childrens car seats, and home energy-saving installations. Most goods and services use the 20% standard rate.

What is a typical tip in the UK?

Restaurant tips are 10 to 15% if service is not already included. Many bills add a 12.5% optional service charge that you can ask to remove. Bars and taxis usually get a small round-up rather than a percentage.
