The real cost of an absent employee

Ask an owner what a sick employee costs him and you almost always get the same answer. The guaranteed pay, and some administration.

That is the smallest item on the list.

The three bills you never receive

What is missing appears on no invoice anywhere, which is exactly why it never comes into view.

First: the revenue or the profit that person does not produce. In a store that is immediate. One salesperson short on a busy Saturday is not just a few hours of wages, it is conversations that never happen. In a services business it is delayed delivery. In production it is capacity standing still or running slower.

Second: the cost of the service that suffers. This is the item that never gets counted at all, and it is treacherous because it only shows up later. The customer who waits longer. The question that never gets asked because nobody has time. The problem that goes unnoticed. That costs you nothing today, and it costs you customers a year from now.

Third: what it does to the colleagues. Work that gets absorbed is rarely done as well, and it puts pressure on the people who did show up. If that happens often enough, those people leave too, and then you have a replacement cost that is a multiple of everything above.

Why it is still worth counting

You will never calculate this down to the euro. You do not need to. What you need is an order of magnitude that holds up, because that is enough to change your decisions.

A rough approach that works: take your gross profit per working day per employee in the role in question. That approximates what does not get produced. Add the guaranteed pay, plus the replacement cost if you cover the gap with temporary staff or overtime.

Run it out for a year and put it next to your absence rate. Most owners are startled by the result, and that is exactly the point. As long as absence stays a percentage, it feels small. The moment it becomes an amount, it turns into one of the largest costs you can actually influence.

What I saw it do myself

The item that gets counted least is the service that suffers. That sounds vague until you measure it, and I measured it during my retail years without intending to.

In periods with a lot of absence, conversion dropped sharply. Not footfall: just as many people came in as usual. Fewer of them bought.

The reason was simple and painful. There were too few people on the floor to receive customers properly. Someone who waits leaves. Someone who is never approached does not buy the more expensive item. Someone whose question goes unasked hesitates and comes back later, or does not.

That is precisely the cost nobody gets an invoice for, and it is also the way to calculate it.

Put your footfall, your conversion and your absence over the same period side by side. If footfall stays flat and conversion drops in the weeks with more absence, you have made the link visible. And then you can convert it: the difference in conversion times your footfall times your average spend is the revenue you missed in those weeks.

At most businesses that amount is a multiple of the guaranteed pay everyone thinks about.

This calculation only works if you measure footfall. If you do not, you cannot tell whether it was your staffing or the street, and the cost of absence stays an assumption.

What you actually measure

An overall absence percentage is too coarse to act on. You want to be able to take it apart.

Short-term against long-term, because those are two completely different phenomena with different causes and different solutions. Per department or location, because if it is concentrated somewhere then that is where it sits, not across your whole organization. Per day of the week, because a pattern around Monday and Friday says something different from absence spread evenly. And per period of the year, so you do not mistake a seasonal effect for a trend.

That breakdown is the difference between knowing you have a number and knowing where to look.

Where you have to be careful

I have to add something here, because this subject has a sharp edge.

Absence is not only a cost item, it is about people who are ill. If you look at this purely as a number and start steering on it without anything else, you get people coming in sick. That costs you more in the end, and it is not the kind of employer you want to be.

So never measure on absence alone. Always put something next to it that says something about the quality of the work or about satisfaction, so you can see whether a drop is a real improvement or just displaced pressure.

And look at your own share before you look at anyone else's. A department with structurally high absence more often has a planning problem or a management problem than a health problem.

Why this makes a good bonus target

Exactly because the cost is so large and so invisible, absence is one of the most commonly chosen targets for a collective bonus plan. Do the arithmetic above and you see why: half a percent less weighs more at most companies than the bonus you pay out for it.

On the condition that your team can see where the counter stands. A target that only becomes visible in December steers nothing.

The claim

At most smaller companies absence is the largest cost that is booked nowhere as a cost. As long as you express it in percentages instead of in euros, it stays invisible.
