GST Calculation Formula

Adding GST (Inclusive Price)

Formula:

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

Example: ₹100 @ 18% GST
GST = (100 × 18) / 100 = ₹18
Total = 100 + 18 = ₹118

Removing GST (Reverse Calculation)

Formula:

Base Price = Final Price / (1 + Rate/100)
GST Amount = Final Price - Base Price

Example: MRP ₹118 @ 18%
Base = 118 / 1.18 = ₹100
GST = 118 - 100 = ₹18

Understanding GST

GST (Goods and Services Tax) is a comprehensive, multi-stage, destination-based indirect tax that is levied on every value addition. Implemented in India on July 1, 2017, it replaced multiple indirect taxes like VAT, Service Tax, Excise Duty, and others.

Key Features of GST
  • Unified Tax System: Replaced multiple taxes (VAT, Excise, Service Tax)
  • Destination-based: Tax collected where goods/services are consumed
  • Multi-stage: Levied at each supply chain level
  • Input Tax Credit: Businesses can claim tax on purchases
  • Pan-India: Single tax rate across India, no state variations
Benefits of GST
  • Reduced Tax Burden: Avoids cascading taxes (tax on tax)
  • Transparent Pricing: Clear breakdown of tax component
  • Simplified Compliance: Single return instead of multiple filings
  • Better for Business: Input credit improves cash flow
  • Consumer Friendly: Uniform prices across regions

Real-World GST Examples

Example 1: Adding GST to Retail Price

Scenario: A clothing retailer buys a shirt for ₹500 (excluding GST) and wants to calculate selling price with 18% GST

Calculation:

  • Base Price: ₹500
  • GST Amount: (₹500 × 18) / 100 = ₹90
  • Selling Price to Customer: ₹500 + ₹90 = ₹590

The customer pays ₹590, retailer gets ₹500, and ₹90 goes to government.

Example 2: Removing GST from Marked Price

Scenario: A product has MRP ₹1,180 (inclusive of 18% GST). Find the net price and GST amount.

Calculation:

  • MRP (Inclusive): ₹1,180
  • Base Price: ₹1,180 / 1.18 = ₹1,000
  • GST Amount: ₹1,180 - ₹1,000 = ₹180

This is useful when you see MRP and want to know the actual product price and tax portion.

Example 3: Essential Items with 5% GST

Scenario: Medicine worth ₹500 (excluding GST) with 5% GST rate

Calculation:

  • Base Price: ₹500
  • GST Amount: (₹500 × 5) / 100 = ₹25
  • Final Price: ₹500 + ₹25 = ₹525

Essential medicines have lower GST to keep them affordable for consumers.

Example 4: Luxury Item with 28% GST

Scenario: A premium car priced at ₹25,00,000 (excluding 28% GST)

Calculation:

  • Base Price: ₹25,00,000
  • GST Amount: (₹25,00,000 × 28) / 100 = ₹7,00,000
  • Final Price: ₹25,00,000 + ₹7,00,000 = ₹32,00,000

Luxury items have higher GST to discourage consumption and generate revenue.
