What is GST and Why Does It Matter?

GST (Goods and Services Tax) is a value-added tax levied on most goods and services sold for domestic consumption. The tax is included in the final price paid by consumers, and businesses collect the tax along the supply chain.

Important Note

GST rates vary by country and sometimes by type of product or service. Always verify the current GST rate for your specific situation.

Understanding GST Calculation Modes

1. Add GST to Amount

When to use: When you know the net amount (before GST) and need to calculate the total price including GST.

Formula:

GST Amount = Net Amount × (GST Rate ÷ 100)

Total with GST = Net Amount + GST Amount

Example:

You sell a product for $100 (net amount) with 18% GST:

  • Net Amount: $100
  • GST Rate: 18%
  • GST Amount: $100 × 0.18 = $18
  • Total with GST: $100 + $18 = $118

2. Remove GST from Amount

When to use: When you see a price including GST and need to know how much GST is included or what the net price is.

Formula:

Net Amount = Total Amount ÷ (1 + (GST Rate ÷ 100))

GST Amount = Total Amount - Net Amount

Example:

You buy an item for $118 including 18% GST:

  • Total Amount: $118
  • GST Rate: 18%
  • Net Amount: $118 ÷ 1.18 = $100
  • GST Amount: $118 - $100 = $18

3. GST Split from Total

When to use: When you have a total amount including GST and want to see both the net amount and GST amount separately.

Formula:

Net Amount = Total Amount ÷ (1 + (GST Rate ÷ 100))

GST Amount = Total Amount - Net Amount

GST Percentage of Total = (GST Amount ÷ Total Amount) × 100

Example:

Total invoice: €236 including 18% GST:

  • Net Amount: €236 ÷ 1.18 = €200
  • GST Amount: €236 - €200 = €36
  • GST Percentage of Total: (€36 ÷ €236) × 100 = 15.25%

Practical Examples and Use Cases

For Business Owners

Scenario: You're pricing products for international customers. A product costs you $50 to produce, and you want to sell it with a 20% markup and 10% GST.

Calculation: Selling price before GST = $50 × 1.20 = $60. With 10% GST added = $66 total price to customers.

For Consumers

Scenario: You see a product advertised for ¥12,000 including 8% consumption tax in Japan. You want to know the actual product price.

Calculation: Using Remove GST mode: ¥12,000 ÷ 1.08 = ¥11,111 product price, ¥889 tax.

For Accountants

Scenario: You need to split a quarterly sales total of €125,000 into net sales and GST for your tax return. GST rate is 21%.

Calculation: Using GST Split mode: Net sales = €103,305.79, GST = €21,694.21.
