Here is what ive worked out......
$65k before tax is $5416 per month
flying 85 hours a month will earn you an extra $1200 per month before tax
Total of $6616 per month before tax.
After tax this will leave you with $4357.75 per month. (IRD website M SL tax code) $4860.30 without a S/L
The type rating will cost $35,000AUD which is $43,189 NZD salary sacrifice over three years is $1,199 per month deductions from your monthly pay cheque.
There will probably be tax-free allowances that may make this more attractive - anyone know??
This leaves us with $3,158 - $3,661 per month ($790 - $915 per week depending on you S/L status)
