Frequently asked questions
How do I add GST to a base price?
Multiply the base price by the GST rate divided by 100 to get the GST amount, then add that to the base price to get the final GST-inclusive price.
When would I need to add GST to a price?
This is useful for quoting a final price to a customer, preparing an invoice, or checking how much tax will be added on top of a pre-tax cost.
Is this the same as the GST Inclusive Calculator?
No — the GST Inclusive Calculator works in reverse: it extracts the base price and GST from an amount that already includes tax. This calculator adds GST on top of a base price.
