GST Calculator India
Calculate GST amount and total price inclusive or exclusive of GST.
About GST Calculator
Calculate GST for any amount and tax rate. Two modes: add GST to a base price, or remove GST from a GST-inclusive price. Shows the tax breakdown into CGST + SGST (intra-state) or IGST (inter-state). Supports all GST slabs: 5%, 12%, 18%, and 28%.
Use Cases
Generating invoices with correct GST, verifying supplier invoices, calculating tax liability, understanding tax-inclusive vs tax-exclusive pricing.
How It Works
Add GST: Tax = Base × Rate/100; Total = Base + Tax. Remove GST: Base = GST-inclusive / (1 + Rate/100); Tax = GST-inclusive - Base.
