How this is worked out
The conversion is a multiplication:
annual = hourly × hours per week × paid weeks
$40 an hour at 38 hours for 52 weeks is $79,040 — 1,976 paid hours, not 2,080, because the ordinary week under the National Employment Standards is 38 hours rather than 40. Using 40 by habit overstates the annual figure by 5.3%.
Superannuation is the second adjustment and it is larger. The superannuation guarantee is 12% of ordinary time earnings, paid by your employer on top of your salary rather than out of it. A $95,000 salary therefore costs your employer $106,400, and that $11,400 is money you receive — just not into your bank account.
total package = salary × 1.12
This matters most when comparing an employed salary with a contract rate, because a contract rate contains no super at all unless you pay it into your own fund. The freelance mode here works backwards from the income you want to keep:
invoice = (income ÷ (1 − tax rate)) + overhead
rate = invoice ÷ billable hours
Put the super you intend to contribute in the business costs field. It is a cost of matching what you had, not an optional extra.
A worked example
- Hourly rate
- $40.00
- Hours a week × paid weeks
- 38 × 52 = 1,976 hours
- Annual salary
- $79,040.00
- Each month
- $6,586.67
- Each fortnight
- $3,040.00
- A $95,000 salary the other way
- $48.08 an hour over 1,976 hours
- $95,000 plus 12% super
- $106,400.00 — super alone is $11,400.00

A salary without super is not the whole number
The superannuation guarantee is 12% of ordinary time earnings from 1 July 2025, the end of a legislated series of increases that began at 9%. It is paid by the employer in addition to salary, into your fund, and it is yours — preserved until you meet a condition of release, but yours.
That makes "salary" an ambiguous word in Australian job advertisements. A $95,000 salary plus super is a $106,400 package; a "$106,400 package including super" is a $95,000 salary. The two are advertised in the same breath and they are eleven thousand dollars apart, so the first question about any offer is which of the two it is.
For this calculator the practical rule is simple: convert the salary component to an hourly rate, then treat super as a separate 12% on top. Mixing it into the hourly figure makes the number incomparable with an award rate, which is quoted excluding super.
38 hours is the ordinary week, and 40 is a habit
The National Employment Standards set maximum weekly hours at 38 for a full-time employee, plus reasonable additional hours. Awards are built around that figure, and award hourly rates are derived from weekly rates by dividing by 38. Using 40 hours in a conversion is not a rounding difference — it is a 5.3% error in the annual figure.
The national minimum wage from 1 July 2026 is $26.44 an hour, or $1,004.90 for a 38-hour week — about $52,245 a year. Very few employees are on the national minimum itself; most are covered by a modern award with higher rates that vary by classification and level, and by an enterprise agreement above that.
Overtime is not set by the NES at all. What you are owed for extra hours comes from your award or agreement, and the patterns differ: many awards pay 150% for the first two or three hours and 200% after that, with different rates on Sundays and public holidays. A calculator that applies one multiplier everywhere is wrong nearly everywhere.
Casual loading exists precisely to replace leave
A casual employee is paid a loading — 25% under most modern awards — specifically because they receive no paid annual leave, no paid personal or carer's leave, no paid public holidays and no notice of termination. The loading is not a bonus for flexibility; it is compensation for the entitlements that are absent.
That makes casual loading the clearest illustration of what this page is about. Four weeks of annual leave plus 10 days of personal leave is roughly six weeks, which over 46 worked weeks is about 13% — and the remaining part of the 25% covers public holidays, notice, redundancy and the insecurity itself.
The comparison people get wrong runs the other way: a casual rate looks larger than the permanent rate for the same work, and it is, but the permanent employee is paid for about six more weeks of the year. Convert both to an annual figure before deciding which is better paid, which is exactly what the weeks and unpaid-weeks fields here are for.
Contract rates, an ABN, and what you now fund yourself
A contractor working under an ABN receives no annual leave, no personal leave, no paid public holidays and — in most arrangements — no superannuation. Some contractors are nonetheless entitled to super: if the contract is wholly or principally for your labour, the hirer may be required to pay the guarantee for you, which is a question about the contract rather than about the label on it.
Sham contracting is the related risk. Presenting what is really an employment relationship as a contract is unlawful, and the Fair Work Ombudsman assesses the substance of the arrangement — control, delegation, commercial risk, whose tools and whose hours — rather than what the paperwork says.
For a genuine contract, price it properly. Take the package you are replacing, including the 12% super, add the leave you no longer accrue, add your own equipment, insurance and accounting, then divide by the hours you can actually bill. On this page's defaults that turns a $110,000 target into $152.68 an hour — close to three times the $52.88 the same money looks like as a salary.
