Employer Cost Calculator Australia 2026-27

Understanding the Total Cost of Employment in Australia

When you hire an employee in Australia, the salary you agree to pay is only one component of the total cost. The Australian employment system requires employers to fund several mandatory on-costs that can add between 15% and 40% to the base salary, depending on your state, industry, and the size of your payroll. Understanding these costs is essential for business planning, pricing decisions, and accurately comparing the cost of employees versus contractors.

This employer cost calculator models the three primary mandatory on-costs: the Super Guarantee contribution (12% of Ordinary Time Earnings for 2025-26), workers' compensation insurance (which varies by industry and state), and payroll tax (which applies only to businesses whose total wage bill exceeds the state or territory threshold). Together, these on-costs can transform an $85 000 base salary into a total employer cost of $98 000 to $108 000, depending on your circumstances.

Beyond these mandatory costs, employers should also budget for a range of non-mandatory but typical employment expenses. Annual leave loading (17.5% of base salary for 4 weeks of leave, as required by many modern awards) adds approximately 1.3% to the annual cost. Long service leave provisions accrue at approximately 1.7% of salary per year in most states. Recruitment costs, including advertising, agency fees, and interview time, can range from $5 000 for junior roles to $30 000 or more for senior and executive positions. Training, professional development, equipment, software licences, and office space are additional costs that vary widely by industry and role.

Super Guarantee: The Largest On-Cost

The Super Guarantee (SG) is the single largest mandatory on-cost for Australian employers. For the 2025-26 financial year, the SG rate is 12% of an employee's Ordinary Time Earnings (OTE). This is the final legislated rate following annual increases from 9.5% that began in July 2021. On an $85 000 salary, the SG contribution is $10 200, bringing the cost to $95 200 before any other on-costs.

OTE includes base salary, commissions, shift loadings, allowances, and some bonuses. It generally excludes overtime payments, reimbursements, and certain lump-sum payments such as accrued leave paid on termination. The distinction matters because employers are only required to pay SG on OTE, not on total earnings. For employees who regularly work overtime, the SG obligation may be lower than expected because overtime payments are typically excluded.

Employers must pay SG contributions at least quarterly, by the 28th day of the month following each quarter end (28 October, 28 January, 28 April, and 28 July). Late payments trigger the Super Guarantee Charge (SGC), which includes the unpaid super, interest at 10% per annum, and an administrative fee. The SGC is not tax-deductible, creating a strong financial incentive to pay on time. Many employers choose to pay super monthly or with each pay cycle rather than quarterly, which reduces administrative risk and improves employee relations.

The maximum super contribution base for 2025-26 is $65 070 per quarter ($260 280 per year). Employers are only required to pay SG on earnings up to this cap, though they may voluntarily contribute more. For employees earning above $260 280, the SG obligation is capped at $31 234 per year (12% of $260 280), regardless of their actual salary.

Workers' Compensation Insurance

Workers' compensation (also known as WorkCover in several states) is compulsory insurance that provides coverage for employees who are injured or become ill as a result of their work. Every Australian employer must hold a workers' compensation policy, and the premium is typically expressed as a percentage of total wages. The rate varies dramatically by industry, ranging from approximately 0.3% for low-risk office-based roles to over 5% for high-risk industries like construction, mining, and heavy manufacturing.

Each state and territory operates its own workers' compensation scheme, so premiums depend on where your employees are based, not where your business is registered. In New South Wales, the scheme is operated by icare (Insurance and Care NSW). In Victoria, it is managed by WorkSafe Victoria. Queensland uses WorkCover Queensland, while Western Australia operates through a private insurer market regulated by WorkCover WA. The premium calculation typically considers your industry classification code, claims history, total wages, and in some schemes, your safety record relative to industry peers.

For a typical office-based business, a workers' compensation premium of 0.5% to 1.5% of wages is common. On an $85 000 salary, this equates to $425 to $1 275 per year. For a construction business, the premium might be 3% to 5%, or $2 550 to $4 250 on the same salary. These costs are tax-deductible as a normal business expense, but they represent a real cash outlay that must be factored into employment budgets.

Payroll Tax by State and Territory

Payroll tax is a state and territory tax levied on employer wage bills that exceed a specified threshold. It is one of the most significant taxes affecting Australian businesses, particularly those with large workforces. The tax applies to total Australian wages, which includes salaries, wages, commissions, bonuses, allowances, fringe benefits, superannuation contributions, and some contractor payments. Each state sets its own rate and threshold, creating a complex compliance landscape for businesses that operate across multiple jurisdictions.

Small businesses with total wage bills below the threshold pay no payroll tax. For example, a NSW business with 10 employees averaging $100 000 each has a total wage bill of $1 000 000, which is below the $1 200 000 threshold, so no payroll tax is payable. If the same business hires two more employees, the wage bill rises to $1 200 000 and payroll tax begins to apply on wages above the threshold. At $1 400 000, the payroll tax would be 5.45% of $200 000 = $10 900.

Victoria has the lowest threshold at $900 000, meaning businesses reach the payroll tax trigger point sooner. Victoria also imposes a surcharge of 0.5% for businesses with national payrolls above $10 million, and an additional surcharge for payrolls above $100 million. The ACT has the highest rate at 6.85% but also the highest threshold at $2 000 000, which means fewer ACT businesses are liable. Queensland offers the most generous general threshold at $1 300 000 and applies a tiered rate structure for larger employers.

Employers with employees in multiple states must register for payroll tax in each jurisdiction where they have workers. Wages are allocated to the state where the employee performs the work, not where the employer is based. Grouping provisions may also apply, requiring related entities (such as companies with common ownership) to combine their wage bills for threshold purposes, which can push grouped entities above the threshold even if individual entities would fall below it.

Calculating the Total Employer Cost: A Worked Example

Consider a medium-sized NSW professional services firm hiring a senior analyst at $110 000 base salary. The total employer cost calculation proceeds as follows:

• Base salary: $110 000
• Super Guarantee (12%): $13 200
• Workers' compensation (0.8% for office-based professional services): $880
• Payroll tax (assuming total wages exceed $1.2M threshold): 5.45% of $110 000 = $5 995
• Total mandatory cost: $130 075
• Cost multiplier: 1.18x

Adding non-mandatory costs: annual leave loading (approximately $1 443), long service leave provision (approximately $1 870), and equipment/IT costs (approximately $3 000), the total cost rises to approximately $136 388, a multiplier of 1.24x. This means the employer pays $1.24 for every $1.00 in base salary. For businesses planning headcount budgets, applying a 1.20x to 1.30x multiplier to base salaries provides a reasonable estimate of total employment cost before adding recruitment, training, and workspace expenses.

The Employer Cost Multiplier by Industry

The cost multiplier varies significantly by industry, primarily driven by differences in workers' compensation premiums and whether the business exceeds the payroll tax threshold.

Multipliers assume payroll tax applies. Businesses below the payroll tax threshold will have a lower multiplier. Figures are indicative and vary by state.

Employee vs Contractor: Understanding the True Cost Comparison

Many business owners consider engaging contractors instead of employees to reduce on-costs. While contractor arrangements eliminate the obligation to pay SG, workers' compensation, and payroll tax (in most cases), the comparison is more nuanced than it appears. Contractors typically charge higher hourly or daily rates to compensate for the absence of benefits. A senior developer earning $140 000 as an employee (total employer cost approximately $165 000 including all on-costs) might charge $900 per day as a contractor, which annualises to approximately $198 000 for 220 working days.

However, the ATO closely scrutinises contractor arrangements to ensure they are genuine and not "sham contracting" designed to avoid employment obligations. If the ATO determines that a worker classified as a contractor is actually an employee (based on factors such as control over how work is performed, provision of tools, exclusivity, and integration into the business), the employer may be liable for retrospective SG payments, payroll tax, workers' compensation premiums, and penalties. The Fair Work Act also prohibits sham contracting, with penalties of up to $18 780 per contravention for individuals and $93 900 per contravention for corporations.

Strategies to Manage and Reduce Employment Costs

• Review your WorkCover industry classification: Ensure your business is classified under the correct industry code. If your actual work activities are lower risk than your current classification suggests, applying for reclassification can significantly reduce premiums. Some schemes also offer premium discounts for businesses with strong safety records and low claims history.
• Monitor payroll tax grouping: If you operate multiple related entities, be aware that grouping provisions may combine your wage bills. Restructuring entity arrangements (where commercially justified) or ensuring each entity claims its share of the threshold can optimise your payroll tax position. Professional advice from a payroll tax specialist is recommended.
• Leverage salary packaging: Offering salary packaging for FBT-exempt items (such as laptops, portable electronic devices, and additional super contributions) can increase employee satisfaction without increasing employer cost. For not-for-profit organisations, the generous FBT-exempt packaging limits of $15 900 per employee per FBT year are a significant recruitment and retention advantage.
• Explore government incentives: Various federal and state programs provide subsidies for hiring. Apprenticeship and traineeship subsidies can cover a substantial portion of wages. The Jobs and Skills Australia program offers wage incentives for hiring in designated sectors. State-specific incentives, such as payroll tax exemptions for new businesses or regional hiring rebates, can further reduce employment costs.
• Invest in workplace safety: Reducing workplace injuries directly lowers workers' compensation premiums over time through experience-based rating mechanisms. Many state schemes offer premium discounts of 10% to 30% for businesses that demonstrate strong safety management systems, return-to-work programs, and injury prevention initiatives.
• Consider flexible work arrangements: Allowing remote or hybrid work can reduce office space costs (a significant non-wage employment expense). Flexible arrangements can also reduce absenteeism and improve retention, lowering recruitment and training costs over time.

Annual Leave Loading and Other Hidden Costs

Many modern awards and enterprise agreements require employers to pay annual leave loading of 17.5% on top of the base pay rate during the four weeks of annual leave. For an employee on $85 000 base salary, the leave loading costs approximately $1 115 per year (17.5% of 4 weeks' pay). Not all employees are entitled to leave loading; it depends on the applicable award, enterprise agreement, or employment contract. The National Employment Standards (NES) under the Fair Work Act do not mandate leave loading, so it is an award-specific or contract-specific entitlement.

Long service leave is another accruing cost that employers must provision for. In most states, employees become entitled to long service leave after 7 to 10 years of continuous service, with the typical entitlement being 8.667 weeks (2 months) of leave after 10 years. The annual provision cost is approximately 1.7% of salary, though many employers do not explicitly budget for this until the liability falls due. Portable long service leave schemes exist in some industries (such as construction and community services) where employees accumulate entitlements that transfer between employers.
