Super vs mortgage calculator FAQs -
frequently asked questions
Q. How do I retrieve a saved calculator?
A. To retrieve a saved calculator, go to the relevant calculator
and click on the "select saved calculator" dropdown menu in the
toolbar (see example below) and select your previously saved
calculator from the list.
If you are not already logged in you will be asked to login. After
entering your username or email and password, you will be able to
select any previously saved results.
Q. Do calculators save data automatically?
A. No, you will need to click on the "Save" icon if you wish to
save your budget.
Q. Why can't I see your calculators on my iPad or iPhone?
A. This calculator was built using Flash at a time when Flash
was accessible to the majority of internet users. Since then, iPads
and iPhones have become very popular and they do not support Flash
files. The MoneySmart team are recreating all our calculators in a
format that will be usable on all devices. Unfortunately, this
process will take a while, so stay tuned!
Q. Are there advanced settings I can change?
A. Yes, within the calculators that you can save, there are some
defaults and assumptions that you can adjust as required. These can
be found within the "How it works" or "Settings" sections.
Q: My super fund return is lower than my mortgage interest
rate, why does the calculator tell me I will have more if I put
spare cash in super?
A: Money salary sacrificed into super is taxed at 15%. Money
credited to your mortgage has been taxed at your marginal tax rate,
likely to be much higher. For example, someone earning between
$37,001 and $80,000 has a marginal tax rate of 32.5% (not including
the Medicare levy). This means there is more money going into
- $1,000 - $325 (tax) = $675 to mortgage
- $1,000 - $150 (tax) = $850 to super
