This is for a friend.
Background, Salary is 70k or so, so a tax rate of 34.5% and I have included the tax of 34.5%-30 % on the way out.
If they sacrifice pre tax 15k, they get
15000 * .345 tax returned = 5175 tax back
15000 * .85 in their super = 12750
Thus a total of 5175 + (12750 * .955) = 5175 + 12176 = 17351
As opposed to doing nothing = 15000-5175 = 9825
Thus the benefit is ~ 7500
Is this correct , so if they did this twice they get ~15k in benefit. I think I have double counted somewhere
Thanks
Your friend is earning 55k if he salary sacrifices $15k a year for 2 years (maximum he can salary sacrifice in the FHSSS is $30000). On an income of $70,000 he pays 14,297. By salary sacrificing 15k he pays $9,422 + $2250 = $11,672. Also they calculate your interest at 4.78% opposed to 2% interest in normal saver accounts. As super has higher interest.
