🔎 What is GST?
GST stands for Goods and Services Tax, a unified tax applied on the supply of goods and services. It replaced multiple indirect taxes like VAT, service tax, and excise duty, making the tax system simpler and transparent.
📐 Formula for GST Calculation
There are two ways to calculate GST:
- For Adding GST to Price:
FinalPrice=OriginalPrice+(OriginalPrice×GST%)Final Price = Original Price + (Original Price × GST\%)FinalPrice=OriginalPrice+(OriginalPrice×GST%)
- For Removing GST from Price:
OriginalPrice=FinalPrice×100100+GST%Original Price = \frac{Final Price × 100}{100 + GST\%}OriginalPrice=100+GST%FinalPrice×100
🧮 Example
- If a product price is ₹1,000 and GST rate is 18%:
GST=1000×18100=₹180GST = 1000 × \frac{18}{100} = ₹180GST=1000×10018=₹180 FinalPrice=₹1000+₹180=₹1180Final Price = ₹1000 + ₹180 = ₹1180FinalPrice=₹1000+₹180=₹1180
