Add GST: GST Amount = Amount x GST Rate / 100

Remove GST: Base Amount = Amount / (1 + GST Rate / 100)

CGST = GST Amount / 2 and SGST = GST Amount / 2

Add GST

Use when your amount is before tax and GST needs to be added.

Remove GST

Use when your amount already includes GST and you need the base value.

CGST and SGST

The calculator splits GST equally for intra-state CGST and SGST display.
