Calculate GST Online Easily (Free Tool)
What is a GST Calculator?
A GST Calculator is an online tool that helps you calculate the Goods and Services Tax for any product or service. It makes GST addition and removal (reverse GST) simple, fast, and error-free.
Whether you are a shop owner, accountant, freelancer, or business manager — a GST calculator saves time and ensures accuracy while preparing bills, invoices, and quotations.
This tool supports:
- Add GST (Calculate price including GST)
- Remove GST (Calculate price excluding GST)
- GST Breakdown (CGST + SGST or IGST)
- GST Slabs: 5%, 12%, 18%, 28%
How GST is Calculated?
1. GST Addition Formula (Price + GST)
GST Amount = (Original Price × GST%) ÷ 100
Final Price = Original Price + GST Amount
2. GST Removal Formula (Price – GST)
Original Price = Final Price ÷ (1 + GST/100)
GST Amount = Final Price – Original Price
Example of GST Calculation
Let’s say item price = ₹1000
GST rate = 18%
Add GST:
GST = (1000 × 18) ÷ 100 = ₹180
Final Price = ₹1000 + ₹180 = ₹1180
Remove GST:
Original Price = 1180 ÷ 1.18 = ₹1000
GST = 1180 – 1000 = ₹180
