What is GST (Goods and Services Tax)?
Goods and Services Tax (GST) is an indirect tax used in many countries, levied on the supply of goods and services. It is a comprehensive, multi-stage, destination-based tax: comprehensive because it has subsumed almost all the indirect taxes except a few state taxes. It is paid by consumers, but it is remitted to the government by the businesses selling the goods and services. For businesses, it's a crucial part of pricing, invoicing, and financial reporting.
The Two Main Types of GST Calculation
When dealing with GST, you'll encounter two primary scenarios, both of which our calculator handles:
- Adding GST (Exclusive Calculation): This is when you have a base price and need to find the final price after adding GST. This is common when you're creating an invoice for a customer.
- Removing GST (Inclusive Calculation): This is when you have a final price that already includes GST, and you need to find the original base price and the amount of tax paid. This is useful for accounting purposes or for consumers who want to know how much tax they paid on an item.
Understanding the Formulas
The math behind GST is straightforward, but it's easy to make a mistake. Here are the core formulas:
To Add GST:
- GST Amount = (Original Cost × GST%) / 100
- Final Price = Original Cost + GST Amount
To Remove GST (Reverse GST):
- Original Cost = Final Price / (1 + (GST% / 100))
- GST Amount = Final Price - Original Cost
What are GST Slabs?
GST is typically levied at multiple rates for different categories of goods and services. These rates are often referred to as "slabs." Common GST slabs in a country like India include 5%, 12%, 18%, and 28%, with some essential goods being exempt (0%) and others like gold having special rates. It's important to know the correct slab for the good or service you are dealing with to perform an accurate calculation.
