How to use this calculator

  1. Enter the price you have.
  2. Enter the VAT or GST rate that applies.
  3. Choose whether your price excludes tax (add VAT) or already includes it (remove VAT).
  4. Click Calculate to see the net price, tax amount, and gross price.
Common mistake: Removing 20% VAT is not subtracting 20% from the gross price. On a $120 gross price, the VAT is $20, not $24. The calculator handles this correctly.

Frequently asked questions

How do you add VAT to a price?

Multiply the net price by the VAT rate and add it on. For example, a $100 price with 20% VAT becomes $120, with $20 of VAT.

How do you remove VAT from a price?

Divide the gross price by 1 plus the VAT rate. For example, $120 with 20% VAT gives a net price of $100 and $20 of VAT. Note that removing 20% VAT is not the same as subtracting 20% of $120.

What is the difference between VAT and GST?

They are the same idea with different names: a consumption tax added at each stage of sale. The UK and EU call it VAT, while countries like India, Australia, and Canada call it GST or HST.
