GST Calculator
Add or remove GST from any amount at the standard slab rates.
Note: This is a straightforward GST arithmetic tool for the 5%, 18% and 40% slabs in force since 22 September 2025 (the rate for your item depends on its HSN/SAC code). It doesn’t account for special rates, cess, or compensation cess that apply to specific goods — confirm the exact rate for your item on the GST portal before filing.
