GST calculator
How it works
In add mode, the calculator increases the base amount by the selected GST rate. In remove mode, it separates the GST portion from the total amount.
Simple example
If an item costs ₹10,000 before tax and GST is 18%, the total becomes ₹11,800 in add mode.
What to look at
Use add mode for pre-tax base values and remove mode when you want to know the base from a total bill amount.
Important note
GST rules can vary by transaction type and compliance need. This tool is a simple educational helper.
