Frequently Asked Questions
Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax that is levied on every value addition. It has replaced many indirect taxes in many countries. In essence, GST is a tax on goods and services sold for domestic consumption. The tax is paid by consumers, but it is collected and remitted to the government by businesses selling the goods and services.
GST can be calculated in two ways:
- Exclusive calculation: Adding GST to a base amount. Formula: GST Amount = Base Price × (GST Rate ÷ 100)
- Inclusive calculation: Extracting GST from a total amount. Formula: GST Amount = Total Price × [GST Rate ÷ (100 + GST Rate)]
Our calculator supports both methods with precise results.
Common GST rates vary by country. In India, for example, there are four main slabs:
- 5%: Essential items and basic services
- 12%: Standard goods and services
- 18%: Most goods and services
- 28%: Luxury goods and sin products
Additionally, some essential goods are taxed at 0%, and luxury/sin goods may have additional cess. Our calculator's Advanced mode helps you select the appropriate rate for your specific product or service category.
In countries like India, GST is split into multiple components:
- CGST (Central GST): Collected by the central government
- SGST (State GST): Collected by the state government
- IGST (Integrated GST): For inter-state transactions
For intra-state transactions, the GST is equally divided between CGST and SGST. For example, if the GST rate is 18%, then 9% will be CGST and 9% will be SGST. Our Breakdown view shows this split clearly.
- Basic Mode: Use for quick calculations with standard tax rates (5%, 12%, 18%, 28%) or any custom rate.
- Advanced Mode: Use when you need to select specific product/service categories with their pre-defined rates.
- Breakdown Mode: Use when you need to see how the GST is split between CGST and SGST components.
Different products and services fall under different GST slabs. To calculate GST for a specific product category:
- Select the appropriate GST rate (5%, 12%, 18%, or 28%) based on the product category
- Enter your amount
- Choose whether you want to calculate GST exclusive (adding GST) or inclusive (extracting GST)
- Use the Breakdown view if you need to see the CGST/SGST split
If you're unsure about which GST rate applies to your product or service, consult the official GST rate schedules or a tax professional.
