A little help with the numbers.
Calculate an amount before or after adding GST. Choose the percentage that applies to your example.
Total including GST
Base amount₹10,000.00
GST amount₹1,800.00
Rate used18%
Amounts rounded to two decimal places. Calculation takes place on your device.
This arithmetic tool does not determine the correct rate, tax treatment, place of supply or eligibility. It does not split CGST, SGST or IGST. Ask your adviser about the treatment of an actual transaction.
How the calculation works
To add GST, multiply the base amount by the percentage and add the result to the base amount.
Working backwards from a total?
To remove GST, divide the inclusive total by 1 plus the percentage expressed as a decimal. The difference is the GST amount.
