How to Use the GST 2.0 Calculator (2026 Update)
Following the major “GST 2.0” reforms effective from September 2025, calculating tax has become simpler but requires knowing the new slabs. The old complex system of 5%, 12%, 18%, and 28% has been streamlined to just three main rates: 5%, 18%, and 40%.
1. Calculating Forward GST (For Billing)
Use the green “Add GST (+)” button when creating an invoice.
- Example: You sell a Mobile Phone (Standard Rate 18%).
- Price: ₹10,000.
- Total Bill: ₹10,000 + 18% = ₹11,800.
2. Calculating Reverse GST (For Costing)
Use the red “Remove GST (-)” button when you bought an item and need to know its pre-tax cost.
- Example: You bought an AC for ₹35,400 (Inclusive of 18% GST).
- Select 18% and click “Remove GST”.
- Result: Actual Cost = ₹30,000. Tax Paid = ₹5,400.

📊 Case Study: The “Insurance” Benefit
The Scenario: Priya, a freelance graphic designer, wanted to renew her health insurance policy. The premium quoted was ₹15,000.
The Old Rules (Pre-Sept 2025): She would have paid 18% GST on top of this (₹2,700), making the total ₹17,700.
The New Reality (2026): Since individual health insurance is now 0% GST, Priya simply selected “0%” in the calculator.
The Outcome: Her total payable amount remained ₹15,000. She saved ₹2,700 instantly due to the new exemption. This case highlights why selecting the correct slab (0% vs 18%) in our calculator is critical.
