Formula: GST = price × rate ÷ 100; total = price + GST

  • For a sale within one state, GST splits equally into CGST and SGST. Between states it is charged as IGST, the same total.
  • Amounts are rounded to the nearest paisa. Cess, if any applies, is not included.

About this tool

Add GST turns a price without tax into the price you charge or pay: GST is the price times the rate divided by 100. Remove GST goes the other way, from a GST-inclusive total back to the base price, by dividing the total by (100 + rate) and multiplying by 100. Many people use the wrong shortcut of subtracting 18% from the total, which gives the wrong base.

For a sale inside one state the tax splits into equal CGST and SGST parts; for a sale between states the same amount is charged as IGST. The panel shows the halves so you can fill in an invoice. Rates are not built in as facts: the GST Council changes them, so pick or type the rate printed on your invoice or listed for your item's HSN code. Cess is not included.

It works in your browser with no sign-in, and amounts are rounded to the nearest paisa. It does not replace your accountant or the GST portal.

बिना GST वाली कीमत पर GST जोड़ें, या GST समेत कुल रकम से GST घटाकर असली कीमत निकालें। CGST और SGST का बँटवारा भी दिखता है। दर वही डालें जो आपके बिल या HSN कोड के लिए तय है, क्योंकि GST परिषद दरें बदलती रहती है।

Questions

How do I remove 18% GST from a total?

Divide the total by 1.18. A bill of ₹11,800 has a base price of ₹10,000 and ₹1,800 of GST. Subtracting 18% of ₹11,800 would give the wrong answer.

What is the difference between CGST, SGST and IGST?

For a sale within a state, the GST is split equally between the central (CGST) and state (SGST) government. For a sale across states, the full amount is IGST. The total tax is the same.

Which GST rate should I use?

Use the rate on the supplier's invoice or the rate for your item's HSN code on the official GST rate finder. Rates and slabs are revised by the GST Council, so this tool doesn't assume one.

Does the tool round to the paisa?

Yes. Tax is rounded to the nearest paisa and CGST plus SGST always add up to the total GST.
