What is GST?
GST is a comprehensive, multi-stage, destination-based tax that is levied on every value addition. In countries like India, it replaced a complex web of indirect taxes (VAT, Service Tax, Excise) to unify the economy under a single tax regime.
GST Calculation Formulas
To ADD GST (Exclusive Price):Final Price = Base Price + (Base Price x GST%)
To REMOVE GST (Inclusive Price):Base Price = Final Price / [1 + (GST% / 100)]
Exclusive vs. Inclusive GST
- Exclusive (Adding GST): The product costs ₹1,000. You apply 18% GST. The customer pays ₹1,180.
- Inclusive (Removing GST): A laptop is sold for ₹50,000 "inclusive of all taxes". To find the real base price and the tax amount for accounting, you use the reverse formula. At 18% GST, the base price is ₹42,372.88, and the tax is ₹7,627.12.
