GST calculator — inclusive and exclusive, CGST / SGST / IGST

Add GST to a price, or take it out of a GST-inclusive amount, and see the CGST, SGST or IGST split.

How it works

• Add GST: GST = amount × rate; total = amount + GST.
• Remove GST: taxable value = amount × 100 ÷ (100 + rate); GST = amount − taxable value.
• Within West Bengal the tax is split equally into CGST and SGST; for a buyer in another state it is charged as IGST.
