What does the GST Calculator do?
The GST Calculator adds or removes GST from any price with a single click. You can work with an exclusive price (GST added on top) or an inclusive price (GST already inside), pick any of India's GST slab rates, and get a clear breakdown of the base price, GST amount, and final total.
Common uses
- Invoicing — add GST to the list price of goods or services you sell so your bill shows the correct tax
- Reconciliation — strip GST out of a supplier invoice to see the pre-tax base amount
- Rate checking — confirm the correct slab (5%, 12%, 18%, or 28%) on goods and services before quoting
- Pricing — decide the final MRP when GST is already included and understand your margin
Key features
- Inclusive and exclusive — switch between adding GST on top of a price or removing it from a price that already includes tax
- Multiple rates — choose from India's GST slabs of 5%, 12%, 18%, and 28% on goods and services
- Breakdown — see the base price, GST amount, and total in one clear result
How it works
Select whether your price is exclusive or inclusive of GST. Enter the price and pick the applicable slab rate. If the price is exclusive, the tool adds the GST percentage; if inclusive, it works backwards to reveal the base price and the tax embedded in the total. The exact amount, the base, and the rate are all shown instantly.
Verdict
The GST Calculator handles both directions — adding or removing GST — across every Indian slab, with a readable breakdown for billing and price checks.
