Complete Guide to GST and VAT Calculation
What is GST?
GST (Goods and Services Tax)is a broad-based consumption tax levied on the supply of goods and services. Countries like Australia, India, Singapore, New Zealand, and Canada use GST. It's typically a flat rate applied to most goods and services, with some exemptions.
What is VAT?
VAT (Value Added Tax) is functionally identical to GST but used in different regions. The UK, EU countries, and many others use VAT. While the name differs, the calculation method is exactly the same.
GST/VAT Calculation Formulas
Add Tax: Gross = Net × (1 + Rate÷100)
Remove Tax: Net = Gross ÷ (1 + Rate÷100)
Example: Australian GST Calculation
Australia has a 10% GST. To add GST to $100: $100 × 1.10 = $110. To find the GST-exclusive amount from $110: $110 ÷ 1.10 = $100. The GST component is $10.
Example: UK VAT Calculation
UK standard VAT is 20%. To add VAT to £100: £100 × 1.20 = £120. To find the VAT-exclusive amount from £120: £120 ÷ 1.20 = £100. The VAT component is £20.
Frequently Asked Questions
How do I calculate GST?
To add GST: Multiply the net amount by (1 + GST rate/100). For 10% GST on $100: $100 × 1.10 = $110. To remove GST: Divide by (1 + rate/100).
What is the difference between GST and VAT?
They're functionally the same tax. GST is used in Australia, India, Singapore, and Canada. VAT is used in the UK, EU, and other regions. Both are calculated identically.
How do I remove GST from a price?
Divide the GST-inclusive price by (1 + rate/100). For 10% GST: $110 ÷ 1.10 = $100 net. The GST is $110 - $100 = $10.
