Mode summary
Use exclusive mode when you know the price before tax. Use inclusive mode when the listed amount already includes GST and you need the pre-tax split.
Example calculation
These examples show both adding GST to a base amount and extracting GST from an already tax-inclusive total.
Example 1
If a base amount is 10,000 and GST is 18%, the GST amount is 1,800 and the total becomes 11,800.
Example 2
If a total already includes 18% GST, inclusive mode separates the pre-tax amount from the tax portion.
