COMMON QUESTIONS
Frequently asked questions
How do I add VAT to a price?
Choose Add VAT, enter the net amount and select the VAT rate. The calculator shows the VAT amount and gross total.
How do I remove VAT from a VAT-inclusive price?
Choose Remove VAT. The calculator divides the gross amount by one plus the VAT rate to recover the net amount.
Why is removing 20% not the same as subtracting 20%?
A price including 20% VAT is 120% of the net price. To recover the net price you divide by 1.20 rather than simply subtracting 20% of the gross total.
Can I use a custom VAT rate?
Yes. Choose Custom and enter the percentage you need.
