GST Calculator

GST both directions — exclusive to inclusive and back — with the Indian slab structure (5/12/18/28%) and the single-rate systems (Australia 10%, New Zealand 15%, Singapore 9%, Canada 5% federal) built into the rate picker.

The operator’s read

Worth knowing

India splits GST into CGST + SGST for intra-state sales (9% + 9% on an 18% item) or a single IGST inter-state — the total is identical; only the invoice line items differ.

Worth knowing

Removing GST divides by 1.18 — subtracting 18% from an inclusive price is the standard invoicing error and understates the taxable value.

Methodology

Inclusive = exclusive × (1 + rate); exclusive = inclusive ÷ (1 + rate). India uses slab rates (5/12/18/28% plus exempt and special categories); Australia 10%, New Zealand 15%, Singapore 9% (2024+), Canada 5% federal GST plus provincial taxes.
