Most Australian SME owners have no clear picture of how their people costs compare to other businesses their size. They know their payroll number, they feel the recruitment invoices when they arrive, and they vaguely track training spend, but very few have ever seen their people costs expressed as a percentage of revenue or benchmarked against what comparable businesses actually spend.
That information gap is expensive. Businesses that overspend on HR functions relative to their revenue carry unnecessary overhead. Businesses that underspend typically have compliance gaps, high turnover, and recruitment processes that are slow and expensive. Neither extreme is sustainable.
This page compiles the most current available data on what Australian businesses spend on HR functions, recruitment, and training, broken down by business size and where possible by industry, so you can benchmark your own position and identify where to adjust.
The most commonly referenced benchmark for HR function cost is the percentage of total revenue allocated to people-related activities beyond base payroll. This includes HR staff costs, recruitment spend, training and development, HR technology, compliance activities, and outsourced HR services.
Gartner's global HR benchmarking research places the median HR functional spend at 0.74-0.80% of revenue across industries. For a $5 million revenue business, that represents $37,000-$40,000 in annual HR spend above and beyond base payroll.
For context, organisations typically spend more on every other support function. Finance and accounting averages 1.25-1.30% of revenue, IT averages 3.14%, sales 4.37-4.47%, and marketing 7.5%. HR consistently receives one of the lowest proportional investments of any business function, which partly explains why so many organisations are caught off-guard by people problems that were preventable.
HR spend varies significantly by business size
The relationship between business size and HR spend as a percentage of revenue is counterintuitive. Smaller businesses typically spend a higher proportion of revenue on HR, not less, because they cannot achieve economies of scale in their people processes. They also rely more heavily on external recruitment agencies and advisers, which carry higher per-transaction costs than in-house equivalents.
A business with 10-20 employees will rarely have a dedicated HR function. That means the owner, a senior manager, or an operations lead is absorbing HR tasks as part of their role, and the cost is buried in that person's salary rather than tracked separately. When this hidden cost is surfaced, it typically runs higher as a percentage of revenue than what a mid-size business with dedicated HR professionals pays.
Average cost per hire
ELMO's HR Industry Benchmark data, based on surveys of over 1,200 HR professionals across Australia and New Zealand, places the average cost to fill a vacant position at $10,500. This is the baseline for a standard hire using a combination of job board advertising and internal recruitment effort.
For roles filled via agency, the cost structure changes significantly. A recruitment agency fee of 15-20% of first-year salary is standard in Australia. For a role at $80,000 filled via agency, that is $12,000-$16,000 in agency fees alone, before any internal HR time, onboarding costs, or manager time is counted.
Cost per hire by role level:
Time to hire
ELMO's research places average time-to-hire at 33.4 days across Australia. Every day a key role sits vacant represents lost productivity and creates workload pressure on existing staff that accelerates burnout and departure risk. Research from Robert Half found that 57% of Australian HR managers have lost a qualified candidate to a faster-moving competitor during a slow hiring process. Speed and thoroughness are in constant tension in most SME hiring processes, and the cost of getting it wrong in either direction is real.
The re-hire problem
The 12% of Australian employees who leave a new job within their first year, according to ELMO research, means a meaningful proportion of recruitment investment generates no return. This is the direct intersection between recruitment cost benchmarks and the cost of a bad hire. For more on that specific cost, see our dedicated analysis of bad hire costs in Australia.
The HR-to-employee ratio is one of the most practically useful benchmarks for growing businesses. It helps define when adding HR headcount becomes justified and how to staff the function efficiently relative to workforce size.
Gartner research places the median HR-to-employee ratio at approximately 2.6 HR professionals per 100 employees across all organisation sizes. This means a 100-person business typically has 2-3 dedicated HR staff, and a 50-person business sits at roughly 1-1.5 HR professionals.
But this average is heavily influenced by large organisations. When segmented by size, the ratios look very different.
For small businesses below 250 staff, the HR-to-employee ratio typically runs 3.4 HR staff per 100 employees or higher. Small business HR functions cannot leverage economies of scale. Every award interpretation, onboarding process, and performance management situation requires proportionally more HR time when there are no standardised systems, no specialist knowledge base, and no clear process playbook.
For medium and larger organisations above 250 staff, ratios typically fall to 1.0-1.2 HR professionals per 100 employees, reflecting the operational efficiency gains from standardised processes, dedicated specialist HR roles, and HR technology investment.
What this means practically: a 30-person business running without dedicated HR support is asking its management team to absorb the equivalent of roughly one full-time HR function. That cost is real. It is just buried in management salaries and owner time rather than visible in an HR budget line.
The benchmark
Gartner's 2024 HR Budget and Efficiency Benchmarks place average annual training and development spend at approximately $202 per employee per year globally. This figure is widely considered low relative to what is needed to maintain a compliant, capable, and engaged workforce, particularly in Australia where award complexity and compliance training requirements are significant.
Australian organisations with proactive learning and development programs typically invest $500-$2,000 per employee per year in structured training. This is a more realistic figure for a business that takes skills development and retention seriously.
What the training budget actually covers
Training spend encompasses formal learning programs, compliance training required under WHS and industry-specific regulations, onboarding programs for new hires, leadership and management development, and software and systems training. In many small businesses, mandatory compliance training consumes the majority of whatever training budget exists before any developmental investment is possible.
AHRI data from Q1 2025 found that 58% of Australian employers planned to increase training investment over the following 12 months, up sharply from 37% in early 2024. The primary drivers are AI adoption requiring reskilling, increasing compliance complexity, and growing recognition that skills gaps are directly contributing to turnover.
The connection between training investment and retention
AHRI data consistently identifies learning and development opportunity as one of the three most effective retention measures available to Australian employers, alongside flexible working arrangements and wellbeing support. Each is used by approximately 36% of employers as a deliberate retention strategy. Businesses that underinvest in training face a compounding problem: skills gaps drive performance issues, performance issues drive turnover, and turnover drains the budget that would have funded training.

For businesses weighing the cost of building HR capability internally against outsourcing it, the comparison is straightforward.
A dedicated in-house HR generalist in Australia costs approximately $75,000-$95,000 in base salary, plus 35% in oncosts (superannuation, leave, workers' compensation), plus recruitment cost to hire them, plus the productivity gap while they ramp up in your specific business. All-in first-year cost: $120,000-$145,000, for one person covering one set of HR skills with no redundancy if they leave.
An outsourced HR arrangement for comparable scope typically costs $18,000-$72,000 per year depending on the level of service, providing access to a team with broader and deeper capability, no recruitment risk, no training period, and no single point of failure. The cost comparison for most Australian businesses under 50-100 employees is strongly in favour of the outsourced model, and the economics shift toward in-house only as headcount and HR volume grows to a point where a dedicated specialist role becomes more efficient.
What percentage of revenue should a business spend on HR?
The Gartner global benchmark sits at 0.74-0.80% of revenue for HR functional spend. For a $5 million revenue business, that is approximately $37,000-$40,000 per year above base payroll. Smaller businesses typically spend a higher proportion due to lack of economies of scale.
What is the average cost to hire an employee in Australia?
ELMO's HR benchmark data places the average cost to fill a position at $10,500 for a standard hire. Via recruitment agency, add 15-20% of first-year salary on top of that. For a role at $80,000 filled via agency, total recruitment cost typically reaches $20,000-$25,000.
How many HR staff should a business have per employee?
The Gartner median is approximately 2.6 HR professionals per 100 employees. For small businesses below 250 staff, the ratio typically runs higher at 3.4 per 100. Larger organisations achieve 1.0-1.2 per 100 through greater process efficiency.
How much do Australian businesses spend on training per employee?
Global benchmarks place average spend at around $202 per employee per year, but Australian businesses with active learning and development programs invest $500-$2,000 per employee annually. Fifty-eight percent of Australian employers planned to increase training investment in 2025.
How long does it take to fill a role in Australia?
ELMO research places average time-to-hire at 33.4 days. Fifty-seven percent of Australian HR managers have lost a candidate to a faster-moving competitor during a slow hiring process.
What is the most common area of overspending in SME people costs?
Agency recruitment fees. Many businesses default to agencies for roles that could be filled with better internal process, representing $10,000-$20,000 in avoidable cost per unnecessary engagement.
What is the most common area of underspending?
HR compliance and people management capability. With wage theft a criminal offence since January 2025 and modern award complexity at record levels, underinvestment in this area carries substantially higher risk than it did previously.
How does outsourced HR compare in cost to in-house HR?
An in-house HR generalist typically costs $120,000-$145,000 in the first year including oncosts and recruitment. Outsourced HR for comparable scope typically runs $18,000-$72,000 per year, making outsourcing significantly more cost-effective for most Australian businesses under 50-100 employees.
