GST exclusive means GST is added on top of the base price. GST inclusive means the displayed amount already includes the GST.

About GST Calculator

The GST calculator adds or deducts Goods and Services Tax to and from amounts, in exclusive, inclusive, or net modes, for whichever single tax rate applies.

Taxes like GST are either included in a displayed price (inclusive) or added on top (exclusive), and businesses must report both figures. This tool converts between them precisely, with a breakdown of the tax component — essential for invoices, quotes, and returns.

When to Use GST Calculator

Use it to prepare an invoice where GST is added on top, to separate the tax portion from a GST-inclusive paid amount, or to price products when your tax rate changes.

Pro Tip

To work backwards from a GST-inclusive total, use inclusive mode — dividing by (1 + rate) gives the pre-tax amount.
