Calculate GST amounts with inclusive and exclusive modes. Choose from preset tax slabs or enter a custom rate. View complete CGST, SGST, and total breakdown.
TooliFyra's GST Calculator Online Free is a precise tool for calculating Goods and Services Tax amounts. Whether you're a business owner, accountant, or consumer, this gst calculator online free helps you quickly determine the tax component of any transaction with both GST Exclusive and GST Inclusive modes.
The calculator uses the new GST 2.0 slabs (3%, 5%, 18% and 40%) as one-click presets and accepts any custom rate, so you can still check an old invoice at 12% or 28%. It shows the original price, total GST, the CGST and SGST split, and the final total.
The 56th GST Council meeting simplified GST to two main rates. The 12% and 28% slabs were removed: items moved from 12% to 5% or 18%, and from 28% to 18% or 40%. A special 40% rate applies to sin and luxury goods.
| GST rate | Used for | Example on ₹1,000 |
|---|---|---|
| 0% (nil) | Fresh, unpacked essentials such as milk, vegetables and fruits | ₹0 GST |
| 3% | Gold, silver and jewellery | ₹30 GST → ₹1,030 |
| 5% (merit rate) | Daily-use goods, many packaged foods (ghee, butter, paneer moved here from 12%) | ₹50 GST → ₹1,050 |
| 18% (standard rate) | Most goods and services; ACs and refrigerators moved here from 28% | ₹180 GST → ₹1,180 |
| 40% (special rate) | Sin and luxury goods, such as aerated sugary drinks | ₹400 GST → ₹1,400 |
Always check the rate for your exact product or service (its HSN or SAC code) on the official GST portal before filing.
Add GST (exclusive): GST = Price × Rate ÷ 100, and Total = Price + GST. Example: ₹10,000 at 18% → GST ₹1,800, total ₹11,800.
Remove GST (inclusive): Original price = Total ÷ (1 + Rate ÷ 100), and GST = Total − Original price. Example: ₹11,800 at 18% → original ₹10,000, GST ₹1,800.
CGST, SGST and IGST: within one state, GST is split equally into CGST and SGST (UTGST in a union territory) — ₹1,800 becomes ₹900 + ₹900. For a sale from one state to another, the full amount is charged as IGST (₹1,800 IGST).

TooliFyra's GST Calculator Online Free provides the most comprehensive CGST/SGST breakdown with both inclusive/exclusive modes — all completely free and private.
GST Exclusive means the tax is added to the base price. For example, ₹1,000 + 18% GST = ₹1,180 total.
CGST (Central GST) and SGST (State GST) each represent 50% of the total GST rate for intra-state transactions. IGST applies to inter-state transactions.
Since 22 September 2025 (GST 2.0), India has two main GST rates: 5% for essentials and 18% as the standard rate, plus a special 40% rate for sin and luxury goods. The old 12% and 28% slabs were removed. Gold stays at 3%.
