Understanding GST Calculation in India
How GST Works in India
GST (Goods and Services Tax) in India follows a dual system where both Central (CGST) and State (SGST) governments collect tax on transactions. For interstate transactions, IGST applies. Our calculator automatically handles these splits, making tax calculation effortless.
GST Rate Guide
Different goods and services attract different GST rates:
- 0.25% - Rough precious stones
- 3% - Gold, silver, jewelry
- 5% - Essential commodities
- 12% - Standard goods and services
- 18% - Most common rate for services
- 28% - Luxury items
Inclusive vs Exclusive GST
When calculating GST, you can either:
- Add GST to your base amount (exclusive calculation)
- Extract GST from the total amount (inclusive calculation)
Our calculator supports both methods, making it versatile for all business needs.
When to Use IGST vs CGST/SGST
For transactions within the same state, GST is split equally between CGST and SGST. For interstate transactions, the entire tax is collected as IGST. Our calculator automatically manages this split based on your selection.
