    23 is the magic number.

    Inclusive to exclusive - Divide by 23 * 20. so $115 /23*20= $100

    So convenient!
    Right. Next!

    Divide by 9 and multiply by 8
    was how the exclusive price
    was calculated from the incl-
    usive price. So, Baldor, what's
    the equivalent new maths for
    the soon-to-be 15% era?
    .

    Maybe they should set the GST % to make it nice and easy maths - say 20%, then you could divide by 6?

    3/23 (used to be 1/9)

    So if the price is $115 then
    multiply by 3 to get $345 then
    divide by 23 to get
    the GST component of $15

    So convenient!

    $100 x 0.85 = $85
    85 x 1.1765 = 100.0025
    so

    Using the old methodology of just diving by a whole number is not as clean any more.

    The new number is 7.66666666666666666666666666666666666666666667

    So there will always be a rounding error.

    started a topic Calculate GST Content From GST Inclusive Price

    Calculate GST Content From GST Inclusive Price

    With the GST changing to 15% how do I calculate the GST content from the GST inclusive price?

    With GST at 12.5% you could just divide the total amount by 9. So what now?

    Cheers.
