Calculate inclusive or exclusive GST

1. Enter the amount using the calculator keypad.
2. Choose Incl. GST when the entered amount already includes GST. This is the default.
3. Choose Excl. GST when GST must be added to the entered amount.
4. Select a GST rate. The taxable value, GST amount and final amount update immediately.

Choose CGST + SGST or IGST

Choose CGST + SGST for an intra-state supply. GST Calci divides the GST amount equally between CGST and SGST. Choose IGST for an inter-state supply. Confirm the correct tax treatment for your transaction before relying on the result.

Use GST rates

Select one of the quick rates on the calculator, open the additional-rate list, or enter a custom rate. You can also change the three quick rates in Settings. Always verify which GST rate applies to the supply.

View and manage calculation history

Open History from the calculator toolbar to search earlier calculations, reuse an entry, mark favourites, delete entries or clear the history. Use Export history to create a CSV file. History and favourites are stored only on your device and do not sync between devices.

Share a calculation

Choose Share to open your device's share sheet with a branded result image and calculation text, including the GST rate, tax type and amount breakdown. Select an installed app or service to send or save it.

The result does not look correct

• Check whether the entered amount includes GST and select Incl. GST or Excl. GST accordingly.
• Confirm the selected GST rate.
• Confirm whether the supply uses CGST + SGST or IGST.
• Clear the current calculation and enter the amount again.

Sharing or export does not open

Make sure your device has an app capable of receiving the shared image, text or CSV file. Close and reopen GST Calci, then try again. If the problem continues, restart the device and install the latest available version of the app.

History or settings are missing

GST Calci has no account or cloud backup. History and settings can be lost if the app is removed, its local data is cleared, or you move to another device without transferring app data.
