Purpose
The GST calculator estimates tax on a taxable value using the GST rate entered by the user. It is useful for quick planning, invoice review and internal checks.
GST = Taxable value × GST rate ÷ 100
Total = Taxable value + GST
Total = Taxable value + GST
Example
If the taxable value is ₹10,000 and the GST rate is 18%, GST is ₹1,800 and the total is ₹11,800.
Limitations
Confirm the correct HSN/SAC classification, rate notification, place of supply, exemption conditions and reverse charge applicability before finalising any invoice or return.
