How is this calculated?

Formula: Exclusive GST = Amount × rate. Inclusive GST = Amount − Amount ÷ (1 + rate).

  • Check the correct HSN/SAC rate before invoicing.
  • Input tax credit depends on your supplier actually filing their return.
  • Registration thresholds differ by state and by type of supply.

Your entries are user inputs; rates and returns you cannot control are assumptions. Results are illustrative, not a statutory computation.
