How GST Calculation Works

Adding Tax (Tax-Exclusive Price)

Tax Amount = Base Price × (Tax Rate ÷ 100)

Total Price = Base Price + Tax Amount

Example: ₹10,000 at 0% GST

Tax = ₹10,000 × 0.00 = ₹0

Total = ₹10,000 + ₹0 = ₹10,000

Removing Tax (Tax-Inclusive Price)

Base Price = Total Price ÷ (1 + Tax Rate ÷ 100)

Tax Amount = Total Price − Base Price

Example: ₹10,000 inclusive of 0% GST

Base = ₹10,000 ÷ 1.00 = ₹10,000

Tax = ₹10,000 − ₹10,000 = ₹0

Frequently Asked Questions
