GST Calculator India - Complete Guide to Goods and Services Tax

GST (Goods and Services Tax) was introduced in India on July 1, 2017, replacing multiple indirect taxes like VAT, Service Tax, and Excise Duty.

GST Rate	Category	Examples

5%	Essential goods	Packaged food, sugar, tea, coffee, edible oil, coal
12%	Standard goods	Processed food, medicines, umbrellas, handbags, cell phones
18%	Most services & goods	Electronics, furniture, IT services, restaurants (AC), financial services
28%	Luxury & sin goods	Cars, motorcycles, AC, refrigerator, cement, tobacco, aerated drinks

Note: Milk, eggs, fresh vegetables, and bread are exempt from GST (0%).

CGST (Central GST): Goes to the Central Government. Applied on intra-state transactions.

SGST (State GST): Goes to the State Government. Applied on intra-state transactions alongside CGST.

IGST (Integrated GST): Goes to the Central Government. Applied on inter-state transactions.

Example: Product worth ₹10,000 with 18% GST:

Intra-state: CGST = ₹900 (9%) + SGST = ₹900 (9%) = ₹1,800 total GST

Inter-state: IGST = ₹1,800 (18%)

Item/Service	GST Rate	Category

Milk, eggs, fresh vegetables	0%	Exempt
Packaged food items	5%	Essential
Butter, cheese, processed food	12%	Standard
Restaurant meals (AC)	18%	Services
Electronics & appliances	18%	Standard
Cars (above 1500cc)	28% + Cess	Luxury
Cement	28%	Construction
Aerated drinks	28% + 12% Cess	Sin goods

Adding GST to base price:

GST Amount = Base Price × GST Rate / 100

Final Price = Base Price + GST Amount

Removing GST from inclusive price:

Base Price = Inclusive Price × 100 / (100 + GST Rate)

GST Amount = Inclusive Price - Base Price

Example: A laptop costs ₹50,000 (before GST) with 18% GST:

GST = ₹50,000 × 18/100 = ₹9,000

Total price = ₹50,000 + ₹9,000 = ₹59,000
