Pay calculator (Australia)

Applies to: Australia

This Australian pay calculator asks one question the others do not: is the figure you are entering before tax or after it? Most people know their take-home, because it is the number that appears in their account — so if that is what you have, this works the tax scale backwards and tells you the salary that produces it.

First, the question every other calculator gets wrong.

What you are paid

How often

Is that before or after tax?

If you only know what lands in your account, pick after tax.

Residency for tax

Super rate

12% is the Superannuation Guarantee. Public sector schemes run well above it — 15.4% is common.

Salary sacrifice

Into super, per pay period, before tax.

Household for the surcharge

Dependent children

Each child after the first lifts the family threshold by $1,500.

Date of your next pay

Optional. With it, the page shows which months carry an extra payday.

I have private hospital cover Use 26 fortnights and 52 weeks, as most calculators do

Why does this ask whether the figure is before or after tax?

Because the answer is wrong otherwise, and nothing tells you. Every calculator asks for gross, and most people know their take-home — it is the number in their account, the one they can check. Someone who enters it into a gross field gets a confident answer to a question they did not ask: what a person earning that would take home.

The payslip that prompted this page had a fortnightly take-home of $4,037. Entered into a gross field elsewhere, the calculator reported what someone grossing $4,037 takes home. Nothing indicated a problem, because from inside the tool there was no problem — it answered the question it was asked.

So this page asks. Pick after tax and it works the scale backwards, trying gross figures until the take-home it computes matches the one you entered to the cent, then reports the salary that produced it.

Why 26.089 fortnights rather than 26?

Because an average year is 365.25 days, and that is 26.089 fortnights and 52.18 weeks. Twenty-six is close enough to look right and wrong enough to disagree with your payslip.

On the payslip that prompted this: a salary of $141,555, with a fortnightly gross of $5,427.03. Multiply that by 26 and you get $141,102.78 — $452.22 short of the salary. It is not a rounding difference and it is not an error on the payslip; it is what happens when a year is treated as 26 fortnights.

Cycle	Periods a year	What most calculators use
Weekly	52.18	52
Fortnightly	26.089	26

Roughly every eleven years, a financial year contains 27 fortnightly pay dates. That is not a bonus and it is not a shortfall. You are paid for the fortnights you work, at an hourly rate; the annual salary is the annualised equivalent of that rate, rather than a pot being divided up.

The 26-and-52 assumption is still available above, labelled as what most calculators use, so if you are reconciling this against another tool you can see exactly where the two part company.

Why is the monthly column not just the year divided by twelve?

Because on a fortnightly cycle that figure never lands in anyone's account. A salary of $104,962 presents as $8,746.83 a month everywhere you look. The reality is two fortnights in most months at $8,074, and three fortnights twice a year at $12,111.

Which months carry the third payday depends on when your first pay of the year falls, so the page asks for it. Leave it blank and you get the smoothed average with a note saying that is what it is. Fill it in and you get the months.

This is the same finding the household budget planner surfaces from the other direction: a budget built on twelve equal months hides both the two months that are better than they look and the ten that are slightly worse.

What does this not model?

Named rather than quietly left out, because a difference you cannot account for is one you will assume is somewhere else:

HELP and HECS repayments — the biggest single omission for anyone with a study debt, and the next thing to build
SAPTO — the seniors and pensioners tax offset
Division 293 tax — the extra 15% on concessional contributions above $250,000 of income
The $1,000 standard deduction — and any other deduction beyond salary sacrifice
The Medicare levy low-income reduction — which phases the levy in rather than charging 2% from the first dollar
Novated leases, family payments and other offsets — all later stages

And PAYG withholding will not match this exactly. Your employer withholds using the ATO's rounded tables, which work per pay period rather than across the year, so a small difference either way is normal and squares up at assessment. On the payslip that prompted this page, over-withholding came to about $40 across the year.

The assumptions this page does make: a full financial year on the same salary, no other income, no deductions beyond the salary sacrifice you enter, and Australian residency for tax purposes unless you change it.

Questions

Is superannuation part of my take-home?: No, which is why it is shown separately. It is paid by your employer on top of your salary and goes to your fund, not your account. Putting it inside a take-home figure is the other way calculators mislead people about what they earn.
Why can I change the super rate?: Because 12% is the legal minimum, not what everyone gets. Public sector schemes run well above it — the payslip that prompted this page is on 15.4% — and a calculator that hardcodes the Guarantee is wrong for everyone in one.
What is the concessional cap room for?: Salary sacrifice and the Superannuation Guarantee count against the same annual cap. The page shows what is left as you enter sacrifice, so you can see the point at which more of it stops being taxed at 15%. It does not model carry-forward of unused cap from earlier years, which many people have and which would raise it.
Does the Medicare levy surcharge apply to me?: Only if you have no private patient hospital cover and your income for surcharge purposes is above the threshold. That income is wider than taxable income — it adds back reportable employer super contributions, which is what salary sacrifice becomes, so sacrificing does not avoid it. Reportable fringe benefits also count and are not modelled here.
Why does my payslip disagree by a few dollars?: Because withholding is done from rounded tables per pay period and this is an annual calculation. Small differences either way are normal and are squared up when you lodge.

For general information and education only. This tool shows an illustration based on the figures you enter - it does not know your circumstances, tax position, or appetite for risk, and nothing here is financial, investment, tax, or legal advice. It is not intended to be relied on when making a decision about any particular financial product. Before acting, check the figures against your own documents and consider advice from a licensed financial professional in your country.

Rules currency not established. 1 of the 9 jurisdiction figures on this page have never been recorded as verified against their source, so no date can honestly be given. Set by Australian Taxation Office. Rates, thresholds and official scales change on each authority’s own schedule, so check the source before relying on a figure for anything that matters.
