Personalkostenplanung (workforce cost planning)

What German staff costs consist of, how a sound plan is built and which items are regularly forgotten in it.

1. What is Personalkostenplanung (workforce cost planning)?

Workforce cost planning is the forward view of the cost that employing people causes in a period. It is more than the sum of gross pay.

The cost is made up of four blocks:

- Direct pay – ongoing pay, allowances, supplements, variable components. - One-off payments – holiday and Christmas pay, awards, bonuses, severance. - Statutory on-costs – employer social security contributions, the U1 and U2 levies under Section 7 AAG, the insolvency pay levy under Section 358 SGB III, employers' liability insurance contributions, the disability levy. - Voluntary and other costs – occupational pensions, benefits in kind, training, workplace and equipment, recruiting.

A sound plan does not work with a flat percentage uplift but follows the structure: contribution ceilings cap the on-costs at higher pay, the levy rates depend on the health insurance fund, and one-off payments fall unevenly across the year.

Added to this are provisions under Section 249 HGB for obligations that have arisen but not yet been paid: untaken holiday, time credit, bonuses, long service awards.

2. Origin and development

Staff costs are the largest cost block in labour-intensive businesses and at the same time the hardest to steer at short notice. That made planning a discipline of its own early on.

Its difficulty has grown over the years because the components have multiplied: variable pay, occupational pensions, benefits in kind, mobility benefits. An uplift of a roughly estimated percentage on gross pay no longer holds today where the composition is unevenly distributed across the business.

3. Core principles and how it works

From the individual case to the total

A sound plan calculates per person or per group and adds up. A flat uplift on the total conceals exactly the effects that matter for planning.

Take the contribution ceilings into account

Above the contribution ceilings, social security contributions do not rise further. Ignoring that overstates the on-costs at higher pay.

One-off payments across the year

They fall in particular months and load liquidity unevenly. An annual view alone misses that.

Provisions are cost

Untaken holiday, time credit and promised bonuses are obligations that have arisen, even though nothing has been paid yet.

Plan for the changes

Bargaining rounds, minimum wage increases, new calculation figures at the turn of the year, joiners and leavers – they are foreseeable and belong in the plan.

4. Who is Personalkostenplanung (workforce cost planning) relevant for?

  • Management and controlling – staff costs are the largest block in many businesses.
  • HR – they supply the volumes and the structural data.
  • Payroll – they know the actual on-costs per person.
  • Accounting – provisions and accruals sit there.
  • Small businesses – planning matters most to them and is least systematic there.

5. How it differs from related terms

- Staff costs and employer gross – employer gross covers pay plus statutory employer contributions; staff costs go beyond that. - Cost planning and headcount planning – headcount planning asks how many people with which skills are needed; cost planning what that costs. - Planned and actual costs – the comparison is where the insight lies; the plan alone is a figure. - Staff costs and on-costs – on-costs are part of staff costs, not their counterpart.

6. Variants and adaptations

- Roll-forward – last year plus expected changes; simple, but blind to structural breaks. - Bottom-up per post – accurate but laborious; the standard case in labour-intensive businesses. - Scenarios – with and without planned hires, with different assumptions on collective pay. - Rolling planning – continuous adjustment instead of a single annual plan. - Full-time equivalents as the volume measure – makes part-time work comparable.

7. Advantages and challenges

Advantages

  • The largest cost block becomes steerable rather than visible only after the fact
  • Hiring decisions rest on a sound basis
  • The liquidity needed for one-off payments becomes foreseeable
  • The need for provisions is recognised early
  • Comparing plan against actual exposes structural deviations

Challenges

  • Laborious where it is done per post
  • Flat uplifts are simple and regularly wrong
  • Turnover and sickness are hard to plan
  • Collective settlements are often still open when the plan is made
  • Provisions are frequently forgotten altogether in small businesses

8. Best practices for implementation

Derive the on-costs from your own payroll

The actual employer contributions of the previous year are a better basis than an estimated percentage.

Plan one-off payments by month

They hit liquidity at particular points. An annual total says nothing about that.

Value the provisions annually

Untaken holiday and time credit are valued obligations and belong in the balance sheet.

Scenarios rather than one figure

With and without planned hires, with different assumptions on collective pay. That makes the uncertainty visible instead of hiding it.

Compare plan against actual

Without the comparison the next plan learns nothing.

9. Tips for employers and employees

For employers

  • **No flat uplift** – the contribution ceilings make it wrong at higher pay
  • **Do not forget the levies** – U1, U2 and the insolvency pay levy are yours alone
  • **Recognise provisions** – untaken holiday and time credit are obligations that have arisen
  • **Calculate bargaining rounds as a scenario** – the settlement is rarely known when you plan

For employees

  • **Your gross is not what the business spends** – employer contributions and levies come on top
  • **That knowledge helps in a pay conversation** – a rise costs the business more than the gross amount

10. Conclusion

Workforce cost planning rarely fails on method and often on the shortcut: a flat percentage uplift on the gross total. It is convenient and, with contribution ceilings, fund-specific levies and unevenly distributed one-off payments, regularly wrong – and it is wrong in a particular direction, overstating the cost of well-paid people, because the ceilings cap the on-costs where a single group-wide burden rate does not.

An employer that derives the actual on-costs from its own payroll, plans one-off payments by month and values its provisions gets a figure it can work with – and, by comparing it against actual costs, one that gets better next year. Three items an imported cost model will not contain deserve their own lines: the U1 and U2 levies, the insolvency pay levy, and the provisions under Section 249 HGB for untaken holiday and time credit.
