How to Use This Tool
Enter the amount you want to calculate with, select the appropriate GST rate from the dropdown, and choose whether you are adding GST to a base price or extracting GST from a total amount. Click 'Calculate' to see the detailed breakdown. Use 'Reset' to clear all fields and start over.
Formula and Logic
For adding GST: Base Price × (GST Rate / 100) = GST Amount. Total Price = Base Price + GST Amount. For extracting GST: Base Price = Total Price / (1 + GST Rate / 100). GST Amount = Total Price - Base Price. The tool uses standard arithmetic to ensure accuracy for invoicing and pricing.

- For e-commerce, consider how GST affects your pricing strategy and profit margins.
- When trading across states or countries, check for inter-state GST rules and exemptions.
