Misconceptions

Common Mistakes to Avoid

Wrong: “A salary always means you earn more than a wage.” The payment structure (fixed vs hourly) does not determine the total amount. A high hourly wage can exceed a low salary.

Right: Wages and salaries are different payment structures, not different pay levels. What matters is the total annual equivalent.

Wrong: “To find a fortnightly salary, divide by 12 and then by 2.” There are 26 fortnights in a year, not 24.

Right: Divide an annual salary by 52 for weekly, by 26 for fortnightly, or by 12 for monthly. Always use the correct number of pay periods.

Concept
Wages vs Salaries
+5 XP

Most Australians are paid either a wage or a salary. The structure affects how you calculate earnings and how your pay changes with extra hours.

A wage is paid based on the number of hours you work. The formula is straightforward:

Wage Formula
$\text{Gross Pay} = \text{Hours Worked} \times \text{Hourly Rate}$

If you work more hours, you earn more. If you work fewer hours, you earn less. Wages are common in retail, hospitality, construction and casual work.

A salary is a fixed annual amount agreed in your employment contract. It is paid in equal instalments regardless of exact hours worked:

Salary Conversions
$\text{Weekly} = \dfrac{\text{Annual Salary}}{52}$
$\text{Fortnightly} = \dfrac{\text{Annual Salary}}{26}$
$\text{Monthly} = \dfrac{\text{Annual Salary}}{12}$
Heads up

Real-World Anchor: As of 2025, the Australian national minimum wage is $24.10 per hour (or $915.90 per week for a full-time 38-hour week). Many workers are covered by awards set by the Fair Work Commission, which specify minimum rates for different industries.

Heads up

Important: A salary does not automatically mean higher pay. A full-time retail worker on $28/hour earns approximately $55,300 per year ($28 \times 38 \times 52). An office worker on a $52,000 salary earns less despite being on a “salary.” Always compare annual equivalents.

What to write in your book
  • Wages are calculated using hours worked × hourly rate.
  • A salary is a fixed annual amount paid in regular instalments regardless of hours.
  • Convert a salary by dividing by 52 (weekly), 26 (fortnightly) or 12 (monthly).
  • Compare annual equivalents to judge which pay structure is better.

Worked Example 1 - Calculating a Weekly Wage
1
Given: Priya works 38 hours per week at an hourly rate of $32.50.
2
Find: Priya’s gross weekly wage.
3
Method: Use the wage formula. $\text{Gross Pay} = 38 \times 32.50 = 1235$

Worked Example 2 - Converting an Annual Salary
1
Given: Marcus has an annual salary of $78,400.
2
Find: Marcus’s fortnightly and monthly pay before tax.
3
Method: Divide by the correct number of pay periods. Fortnightly: $78{,}400 \div 26 = 3{,}015.38$. Monthly: $78{,}400 \div 12 = 6{,}533.33$.

Concept
Reading an Australian Pay Slip
+5 XP

Every Australian employer must provide a pay slip within one day of paying an employee. By law, it must show:

  • The employer’s and employee’s names
  • The pay period dates
  • Hours worked and the hourly rate (for wage earners)
  • Gross pay - total before deductions
  • All deductions (PAYG tax, Medicare levy, superannuation)
  • Net pay - the amount actually paid
  • Any loadings, penalties or allowances
Heads up

Scope note: This lesson focuses on reading gross and net pay. Detailed tax calculations and superannuation are covered in later financial mathematics topics.

What to write in your book
  • An Australian pay slip must show gross pay, all deductions, and net pay.
  • Gross pay is total earnings before tax and other deductions are taken out.
  • Net pay (take-home pay) is what the worker actually receives.
  • Employers must provide a pay slip within one day of paying an employee.
On a pay slip, what does "net pay" mean?

Model Answers

Normal pay: $38 × $32.40 = $1,231.20

Overtime rate: $32.40 × 1.5 = $48.60 per hour

Overtime pay: $4 × $48.60 = $194.40

Gross pay: $1,231.20 + $194.40 = $1,425.60

Marking guidance: 1 mark for normal pay calculation, 1 mark for overtime rate and pay, 1 mark for correct total.

Job A annual: $30 × 38 × 52 = $59,280

Job B annual: $62,000

Difference: $62,000 - $59,280 = $2,720

Conclusion: Job B pays $2,720 more per year.

Marking guidance: 1 mark for Job A calculation, 1 mark for identifying Job B amount, 1 mark for correct comparison, 1 mark for clear conclusion with units.

There are 26 fortnights in a year, not 24. Dividing by 24 assumes only 48 weeks of pay, ignoring 4 weeks.

Correct fortnightly pay: $52,000 ÷ 26 = $2,000.00

Incorrect fortnightly pay: $52,000 ÷ 24 = $2,166.67

Difference per fortnight: $2,166.67 - $2,000.00 = $166.67

Annual difference: $166.67 × 26 = $4,333.42

Marking guidance: 1 mark for explaining 26 fortnights, 1 mark for correct calculation, 1 mark for incorrect calculation, 1 mark for difference, 1 mark for clear reasoning.
