When Saving on HR Comes at a Cost

HR personnel costs, recruitment budgets, HR systems or leadership programmes: HR expenses are visible, clearly allocated and, at first glance, easy to quantify.

Their impact, however, follows a different logic.

It becomes apparent through available capacity, shorter vacancies, stable teams, better leadership decisions or successful transformations. As a result, the impact often emerges later and in a different part of the organisation.

Whether an HR expense is worthwhile depends on its contribution to the business. However, this contribution is usually much harder to quantify than the expense itself.

The HR budget only tells part of the story

Over the past few weeks, we have therefore explored HR costs from three perspectives:

Why HR comes under pressure so quickly in cost discussions.

Which activities and services are actually included in the HR budget.

And what additional costs can arise when spending on these activities is reduced.

The discussion in the comments highlighted another important point: The consequences of insufficient HR investment often only become visible later and outside the HR function.

The hidden costs appear in day-to-day operations

An unfilled position initially appears as a cost saving in the budget. ✅

In day-to-day operations, however, other employees have to take on additional responsibilities, priorities are shifted and projects are delayed.

Insufficient workforce planning does not appear as a separate cost item. Its consequences become visible through expensive overtime payments, temporary staffing solutions, project delays caused by capacity shortages or unused resources resulting from overstaffing.

Employee turnover is also more than just a metric in HR reporting. When an employee leaves, experience, relationships and knowledge are lost. At the same time, recruitment and onboarding have to start again, while the existing team absorbs the additional workload.

In a comment on one of our posts, similar consequences were described in the context of transformations: Insufficient HR investment can lead to project delays, excessive workloads for key employees and loss of knowledge.

This highlights an important point. The workforce perspective needs to be part of ongoing strategy reviews, but also needs to be considered from the very beginning of a transformation – not only when a lack of capacity or skills puts implementation at risk.

There is often a significant time gap between savings and their consequences

For many HR expenses, the investment and its impact occur at different points in time.

• Reducing the training budget provides short-term cost relief. At the same time, it increases the risk of skills gaps developing and critical expertise becoming unavailable in the future. This point was also raised in our comments: Cutting investment in future skills and competency development may reduce costs today, but could compromise the organisation’s long-term competitiveness and ability to adapt.
• Cutting one FTE too many from the HR team reduces personnel costs in the short term. However, the additional workload can create costs through sickness absence caused by excessive pressure, errors resulting from time constraints or delays in providing services to the business.
• Cancelling a leadership programme initially removes an expense. However, the consequences of insufficient leadership development may only become apparent later through slower decision-making, conflicts, employee turnover or weaker execution of strategic initiatives.

This time gap distorts the calculation: The savings are immediately visible. Their consequences, however, are spread across months, cost centres and areas of responsibility.

Turning HR expenses into a solid business case

We are all familiar with the demand for “effective HR”.

However, measuring HR's impact through a single financial metric often falls short. The contribution of an HR initiative can be reflected in several outcomes at the same time:

• Better workforce planning influences personnel costs, overtime and the organisation’s ability to deliver.
• An effective recruitment process influences time to fill, quality of hire and workload within teams.
• Targeted skills development influences the ability to fill positions internally, organisational adaptability and the future need for external expertise.

To turn these considerations into a solid business case, five questions need to be answered before making an investment:

What specific business problem are we trying to solve?

What direct and indirect costs does this problem currently create?

What are the expected consequences of not taking action?

In which areas and over what period will the impact become visible?

Which few key metrics can actually be used to monitor progress?

This turns a general demand for “effective HR” into a measurable and accountable business decision.

HR costs are no exception

Not every tool, programme or additional process is a good investment. HR, too, must prioritise budgets, challenge existing services and discontinue activities that do not deliver sufficient value.

This requires weighing the visible expense in the HR budget against the expected business benefits and the potential consequences of not investing. HR, Finance and the business functions each bring different perspectives to the same decision.

Our posts on HR costs and the discussions that followed have highlighted one thing above all:

What matters is not only how much HR costs, but also what changes within the organisation when certain investments are not made.
