Frequently Asked Questions
What is GST?
GST stands for Goods and Services Tax. It is an indirect tax levied on the supply of goods and services.
What is the difference between GST inclusive and GST exclusive?
GST inclusive means the price already includes the tax amount. GST exclusive means the tax is yet to be added to the base price.
How do I calculate GST exclusive amount?
To add GST, multiply the base amount by the GST rate percentage, and divide by 100. (e.g., base of 1000 with 18% GST is 1000 * 0.18 = 180).
How do I remove GST from a total inclusive amount?
Use the formula: Original Price = Inclusive Price / (1 + (GST Rate / 100)). The tax amount is then the inclusive price minus the original price.
What is CGST, SGST, and IGST?
CGST (Central GST) and SGST (State GST) apply to intra-state transactions and are split 50/50. IGST (Integrated GST) applies to inter-state transactions and goes to the Central Govt.

In India, standard GST rates are structured across 5%, 12%, 18%, and 28% tax slabs.
