What is GST?

GST (Goods and Services Tax) is a destination-based indirect tax applied to the supply of goods and services.

• CGST (Central GST)
• SGST (State GST)
• IGST (Integrated GST)

Types of GST in India

1. CGST

Collected by Central Government on intra-state supply.

2. SGST

Collected by State Government on intra-state supply.

3. IGST

Collected on inter-state supply.

GST Rates in India

Common GST rates:

• 0% – Essential items
• 5% – Basic goods
• 12% – Processed goods
• 18% – Standard rate
• 28% – Luxury goods

How to Calculate GST

Adding GST Formula

GST Amount = (Base Amount × GST Rate) / 100
Final Price = Base Amount + GST Amount

Removing GST Formula

Base Amount = Inclusive Price ÷ (1 + GST Rate/100)

Example of GST Calculation

Suppose product price = ₹10,000
GST rate = 18%

GST = 10,000 × 18% = ₹1,800
Total = ₹11,800

If intra-state:

CGST = ₹900
SGST = ₹900

Why Use a GST Calculator?

Manual GST calculations often lead to errors. A GST calculator:

• Saves time
• Ensures accuracy
• Helps invoice generation
• Assists compliance
• Helps small businesses

GST for Businesses

Businesses registered under GST must:

• Issue GST invoices
• File GST returns
• Maintain tax records
• Claim Input Tax Credit (ITC)

Reverse GST Calculation

If price is GST-inclusive, reverse GST calculation helps determine the original taxable value.

Example:

Inclusive price = ₹11,800
GST = 18%

Base Price = 11,800 ÷ 1.18 = ₹10,000
