Possible. I am on the low end of the scale as my Master's degree not recognized and no work experience considered . My teaching peers with similar years of teaching experience have hit monthly $5.8k to $6k per month as a subject head (with increments for honors and work experience).

So calculation wise.

$6k x (12mths + 2.5 mths (Good PB) + 1 mth (AWS) + 0.5 mth + $300 (JUNE) + 1 mth (Year end estimated)) = $6k x 17 mths = $102.3k

However, I am still not there yet Still some ways away.
