GST Formula Guide
Here are the mathematical formulas used to compute Goods and Services Tax:
➕ GST Exclusive Formula
Used when adding tax to a base price.
GST Amount = (Base Price × Rate) / 100Total Price = Base Price + GST Amount
➖ GST Inclusive Formula
Used to find the original price from a total bill.
GST Amount = Total - [Total / (1 + Rate/100)]Base Price = Total - GST Amount
Tax Heads: CGST, SGST, and IGST Explained
Depending on the location of the buyer and seller, GST is categorized into three types:
- CGST (Central GST): Collected by the Central Government on an intra-state sale (e.g., Seller in Mumbai, Buyer in Pune).
- SGST (State GST): Collected by the State Government on an intra-state sale. Usually, the total tax rate is split equally between CGST and SGST.
- IGST (Integrated GST): Collected by the Central Government for inter-state sales (e.g., Seller in Delhi, Buyer in Bangalore).
Frequently Asked Questions (FAQ)
Which GST rate applies to my product?
It depends on the HSN (Harmonized System of Nomenclature) code. Essentials are taxed at 5%, standard electronics/services at 18%, and luxury items at 28%.
Can I calculate GST on MRP?

Under RCM, the recipient of goods/services pays the GST instead of the supplier. This usually applies to specific categories or purchases from unregistered dealers.
