Training expenses

Training expenses measure the total organisational spend on employee learning and development, including formal programmes, external courses, certifications, coaching, and the time cost of training delivery. It is the primary financial metric for evaluating the scale and efficiency of the L&D function.

What are training expenses?

Training expenses represent the total investment an organisation makes in developing the skills, knowledge, and capabilities of its workforce. The metric encompasses both the obvious costs (course fees, platform subscriptions, external trainer fees) and the less visible costs (employee time spent in training, internal trainer preparation time, and administrative overhead of the L&D function).

This metric matters for two reasons. First, it quantifies the organisation's commitment to employee development. Companies that underinvest in training often see the consequences in skill gaps, lower productivity, reduced innovation, and higher employee turnover as employees seek growth opportunities elsewhere. Second, it provides the denominator for training ROI calculations. Without knowing what was spent, it is impossible to evaluate whether the investment produced a worthwhile return.

Training expenses are most useful when expressed as a per-employee figure, a percentage of payroll, or a percentage of revenue. These normalised metrics enable meaningful comparison across time periods, departments, and industry peers. A company spending 200,000 pounds on training sounds substantial, but if it has 2,000 employees, that is only 100 pounds per person, which is likely insufficient.

The relationship between training spend and business outcomes is not linear. There is a minimum threshold below which training investment is too low to have meaningful impact, and a point of diminishing returns above which additional spend does not produce proportionally better outcomes. The goal is to find the level of investment that produces the best return, not simply to spend more or less.

The most common mistake in tracking training expenses is excluding the cost of employee time. If 100 employees each spend 40 hours per year in training, and their average hourly cost is 35 pounds, the time cost alone is 140,000 pounds. Excluding this produces a misleadingly low training expense figure.

How to calculate training expenses

Total training expenses should include all direct and indirect costs associated with employee learning and development. The per-employee figure provides the most useful benchmark for comparison. Expressing training spend as a percentage of total payroll or total revenue provides additional context for understanding the organisation's relative investment level.

The cost categories to include are: external training providers and course fees, learning management system and platform subscriptions, internal L&D team salaries and benefits, training materials and content development, facilities and equipment for in-person training, travel and accommodation for off-site programmes, certification and accreditation fees, and the opportunity cost of employee time away from productive work.

Decomposing training expenses with a metric tree

A metric tree breaks training expenses into their cost components and connects them to the outcomes they are intended to produce, creating a clear view of where money is being spent and whether it is delivering value.

This decomposition reveals the cost structure of the L&D function. In many organisations, the single largest training cost is employee time, yet it is the component most often excluded from the calculation. When time costs are included, the total training investment is typically two to three times the direct programme spend.

The tree also enables efficiency analysis. If 40% of the training budget goes to external providers while internal trainers are underutilised, there may be an opportunity to shift delivery in-house for common topics. If onboarding training consumes a disproportionate share of the budget, it might indicate high turnover requiring frequent re-onboarding rather than excessive programme costs.

Training expense benchmarks

SegmentTypical spend per employeeContext
Overall average£500 to £1,500 per yearWide variation by industry and company size. Organisations with strong L&D cultures spend significantly more.
Technology£1,000 to £2,500Rapid skill evolution requires continuous investment. Certification programmes, conference attendance, and learning platforms drive higher spend.
Financial services£800 to £2,000Regulatory training requirements create a baseline spend. Compliance training is mandatory and represents a significant portion of the total.
Healthcare£1,200 to £3,000Clinical training, continuing professional development, and mandatory certifications drive above-average investment.
Retail and hospitality£200 to £600Lower per-employee investment reflecting high turnover and shorter training cycles. Focus on operational skills and product knowledge.
Professional services£1,500 to £3,500Knowledge-intensive industries invest heavily in developing their primary asset: their people. Includes significant spend on leadership development.

As a percentage of payroll, most organisations spend between 1% and 3% on training. Companies recognised as top employers for talent development typically spend 3% to 5% of payroll. Below 1%, the investment is likely insufficient to maintain skill levels, let alone develop new capabilities.

How to optimise training spend

  1. 1

    Align training investment with strategic priorities

    Every training pound should connect to a business need. Map training programmes to the skills required for the organisation's strategic goals. If the strategy depends on cloud migration, invest in cloud engineering certifications. If growth depends on consultative selling, invest in sales methodology training. Cut programmes that do not connect to current or near-term business needs.

  2. 2

    Measure training effectiveness, not just completion

    Tracking course completion rates tells you nothing about whether training changed behaviour or improved performance. Implement evaluation at multiple levels: learner satisfaction, knowledge retention, behaviour change on the job, and business impact. Only training that produces measurable outcomes justifies continued investment.

  3. 3

    Shift towards blended and on-demand learning

    Traditional classroom training is the most expensive delivery method when employee time costs are included. Blended models that combine self-paced digital learning with focused in-person sessions reduce time away from productive work while maintaining the interactive elements that drive skill application.

  4. 4

    Build internal expertise for recurring programmes

    External trainers and consultants charge premium rates. For topics that are delivered repeatedly (onboarding, core technical skills, management fundamentals), develop internal trainers who can deliver at a fraction of the cost. Reserve external providers for specialist topics that require deep expertise the organisation does not possess.

  5. 5

    Track training spend by programme and connect to outcomes

    Break training expenses down by programme, department, and employee level. Connect each programme to measurable outcomes: did sales training increase win rates? Did technical training reduce incident resolution time? Did management training improve employee engagement scores? This data enables evidence-based decisions about where to increase or decrease investment.

Tracking training expenses with KPI Tree

KPI Tree lets you model training expenses as a detailed cost tree connected to the outcomes each programme is designed to produce. Each training programme becomes a node with cost, participation, and effectiveness metrics, creating a clear return-on-investment view for every learning initiative.

The tree connects training spend to downstream business metrics: technical training links to engineering productivity and incident rates, sales training links to win rates and deal sizes, management training links to engagement scores and team retention. This makes the business case for L&D investment concrete and defensible.

Segmenting by department, role level, and programme type reveals where training investment is concentrated and whether the allocation matches strategic priorities. If 60% of the training budget goes to compliance training while the organisation's stated priority is leadership development, the tree makes this misalignment visible.
