What is this tool?

A lightweight, rapid utility for business owners to either ADD GST to a net price to find the final customer charge, or EXTRACT GST from a gross receipt to find the base value and tax component for accounting purposes.

How it works?

Enter your amount and the tax percentage (e.g., 5%, 10%, 18%). Click "Add GST" to calculate the final price. Click "Extract GST" if the price already includes tax and you need to reverse-calculate the base price.

Is it free for all?

Yes, 100% Free! Perfect for quick invoicing and accounting logging.
