How this tax calculator works
Goods and Services Tax (GST) is charged on most goods and services in India. This tool adds GST to a net price or removes GST from an inclusive total, then shows the tax split.
Intra-state supplies usually split the rate into CGST and SGST. Inter-state supplies use IGST at the full rate. If you sell outside India, use the VAT calculator for local VAT instead.
Remove GST: Net = Amount / (1 + Rate / 100) • GST = Amount − Net
How to use this calculator
- Choose Add GST or Remove GST.
- Enter the amount and pick a slab (3%, 5%, 12%, 18%, 28%) or type a custom rate.
- Select intra-state or inter-state so you see CGST+SGST or IGST correctly.
Worked example
Example: ₹10,000 net at 18% intra-state becomes ₹11,800 total, with ₹900 CGST and ₹900 SGST.
If a client quotes ₹11,800 inclusive of 18% GST, switch to Remove GST to find the taxable value and tax portion.
When this helps
Built for Indian invoices, quotations and quick checks before you raise a bill.
What this does not cover
HSN classification, exemptions and e-invoice rules are not decided here. Confirm the correct slab for your goods or service under current GST law.
