Calculating GST at 15% - Excel

Not to pass judgement, but in some cases it's not lack of intelligence, but SPLD's, such as dyscalculia, which make even basic mathematics dumbfounding. Tools like Excel can help exceedingly in this regard.

You guys all so very wrong.

To calculate the GST on a item which has no GST:

Item cost excl GST / 7.6666666666 = Price of GST
Item cost + GST = Price Inc GST.

$1066 / 7.6666666666 = $139.04
$1066 + $139.04 = $1205.04

The price Inc GST is $1205.04
