Add GST to a price or remove it from a GST-inclusive price. See CGST, SGST and IGST split instantly.
How is GST calculated?
To add GST: GST = amount × rate / 100. To remove GST from an inclusive price: GST = amount × rate / (100 + rate). For a same-state sale the GST is split equally into CGST and SGST. For a sale to another state the full GST is charged as IGST.
Which GST rate should I use?
The rate depends on the HSN or SAC code of your goods or service. Use our HSN / SAC code finder to find the code, then check the current rate on the GST portal, because rates change.
