How to use it
A quick estimate, without the spreadsheet.
Inputs and units
Enter an amount in GBP, select the applicable 20%, 5% or 0% VAT rate, then choose whether VAT is included.
Formula
Adding VAT multiplies the net price by 1 + rate. Removing VAT divides the gross amount by 1 + rate; VAT is the difference.
Worked example
£120 including 20% VAT contains £100 net and £20 VAT.
Assumptions and limitations
This calculates a selected rate; it does not determine which products qualify or whether you must register. Zero-rated and exempt supplies have different legal treatment despite both producing no VAT here.
