About the VAT Calculator
How do I remove VAT from a price?
Divide the gross price by 1 plus the rate (1.2 at 20%). The calculator does this and shows the VAT included, at whatever rate you enter.
Can I share the calculator with my team or a client?
Yes. The Room keeps the calculator live: anyone with the link can change the numbers and see the result update, with the method and assumptions on the same page.
