What is a GST Calculator?

A GST (Goods and Services Tax) calculator is a tool that helps you determine the gross or net price of a product or service based on the applicable GST rate. It can calculate the price by adding GST to a base amount (Exclusive) or extracting the GST component from a total amount (Inclusive).

Exclusive vs Inclusive GST

GST Exclusive: The tax amount is added to the base price of the item. This is commonly used in B2B transactions or wholesale pricing.
GST Inclusive: The final price of the item already includes the tax amount. This is typically how products are priced for retail consumers (B2C).

Frequently Asked Questions

GST Exclusive means the tax is added to the base price (Price + Tax = Total). GST Inclusive means the total price already contains the tax, and you are calculating backwards to find the base price and the tax component.
For Exclusive: GST = (Amount × Rate) / 100. For Inclusive: GST = Amount - [Amount / (1 + Rate/100)].
CGST (Central GST) and SGST (State GST) are the two components of GST for intra-state sales. They are exactly half of the total GST rate. For inter-state sales, IGST (Integrated GST) is applied, which equals the full GST rate.
