GST Calculator India (2026): Calculate CGST, SGST & IGST
💡 Bhai Ki Advice (Inclusive vs Exclusive): Freelancers aur dukaandar sabse badi galti invoice banate time karte hain! Agar client ne bola hai “₹10,000 milenge”, toh usse pucho “GST Inclusive ya Exclusive?” Agar wo ‘Inclusive’ bole, toh aapka GST Remove tool use karo, warna ₹10,000 mein se hi GST kat jayega aur aapko kam paise milenge. Agar wo ‘Exclusive’ bole, toh GST Add tool use karke ₹11,800 ka bill banao. Aur haan, Intra-state (same state) ke liye CGST+SGST lagana, aur Inter-state (dusri state) ke liye IGST!
The Goods and Services Tax (GST) is an indirect tax used in India on the supply of goods and services. For business owners, CA professionals, and freelancers, creating accurate invoices and understanding tax liabilities is a daily requirement. Our India GST Calculator is a dual-function tool designed to help you quickly figure out the exact tax amount. Whether you need to add GST to a base price or extract the GST amount from a total price (reverse calculation), our tool provides instant, error-free results based on the 2026 tax slabs.
How to Calculate GST for Invoices
Ensure your billing is 100% compliant by following these steps:
- Enter the Base Amount: This is the price of your product or service.
- Select the GST Rate Slab: Choose the applicable tax rate for your product category. The standard slabs in India are 5%, 12%, 18% (most services), and 28%.
- Choose ‘Add’ or ‘Remove’ GST:
- Add GST (Exclusive): Use this when the base amount does not include tax. The calculator will add the tax on top to give you the final billing amount.
- Remove GST (Inclusive): Use this when the total amount already includes the tax, and you need to find the original product price and the tax component.
- Check the Split (CGST/SGST vs IGST): The tool automatically splits the tax. If selling within your own state, you bill half as CGST (Central) and half as SGST (State). If selling to another state, you bill the full amount as IGST (Integrated).
