GST Calculator - Online GST Calculation Made Easy

What is GST?

GST (Goods and Services Tax) is a consumption-based tax applied to goods and services at every stage of production or distribution. It is widely used in many countries as a unified tax system.

GST replaces multiple indirect taxes and ensures transparency in taxation. It is typically charged as a percentage of the transaction value.

For example:

• If GST rate = 10%
• Product price = $100
• GST amount = $10
• Final price = $110

Formula:

• GST Amount = (Original Amount × GST Rate) ÷ 100
• Final Price = Original Amount + GST Amount

Example:

• Original price: $500
• GST rate: 12%
• GST = $60
• Final price = $560

This feature is useful for:

• Businesses creating invoices
• Retail price calculations

Remove GST from a Total Amount

If you have the total price including GST and want to find the original amount:

Formula:

• Original Price = Total Amount ÷ (1 + GST Rate/100)

Example:

• Total price: $110
• GST rate: 10%
• Original price = $100
• GST amount = $10

This is useful when:

• Reviewing supplier invoices
• Auditing financial records
• Calculating pre-tax pricing
