What Is GST?
The complete form of GST is Goods and Services Tax.
It is an indirect tax applied to the supply of goods and services in India, replacing multiple earlier taxes.
GST is charged at different rates such as 5%, 12%, 18%, and 28%, depending on the product or service.
GST Inclusive vs GST Exclusive – What’s the Difference?
Understanding inclusive and exclusive GST is necessary for correct billing.
GST Exclusive
- GST is added on top of the base price
- Commonly used in invoices and pricing
- Example: ₹1,000 + 18% GST = ₹1,180
GST Inclusive
- GST is already included in the total amount
- Commonly used in retail pricing
- Example: ₹1,180 (inclusive of 18% GST)
A reverse GST calculator helps you find the original price when GST is already included.
How GST Is Calculated
GST calculation depends on whether GST is inclusive or exclusive:
- GST Exclusive Calculation:
- GST Amount = Base Price × GST Rate
- GST Inclusive Calculation:
- Base Price = Total Amount ÷ (1 + GST Rate)
Our GST calculator online automatically applies these formulas, so you don’t need to calculate anything manually.
