Cost of absence calculator

Absence costs more than the pay for the missing days. This calculator adds employer on-costs and the overtime or agency cover that absence triggers, so you see the full figure.

Cost = paid days × daily pay × (1 + on-costs) + covered days × cover cost

Excludes harder-to-measure effects such as lost output and manager time, so the real figure is usually higher.

Why absence costs more than it looks

Most organisations count absence in days. Finance sees it as money, and the money is usually larger than the pay for the missing days, because each absence that needs cover is paid twice: once to the absent person (if paid) and again, often at a premium, to whoever covers.

Worked example

ItemCalculationCost
Pay for absent days400 days × £150 × 1.20 on-costs£72,000
Cover400 × 60% covered × £225 per day£54,000
Total£126,000

In this example, cover adds 75% on top of the pay for absent days. Reducing the share of absence covered at premium rates, for example by planning cover from people already on shift, is often the quickest saving.

Frequently asked questions

How do you calculate the cost of absence?

Add two parts. Direct cost is the pay for absent days that are paid, including employer on-costs such as payroll taxes and pension. Cover cost is what you spend replacing the absent person, usually overtime or agency staff. Total cost = paid absence days × daily pay × (1 + on-cost %) + covered days × daily cover cost.

What are the hidden costs of absence?

Beyond pay, absence triggers overtime or agency cover at premium rates, manager time spent rearranging shifts, lower output from short-staffed teams, and pressure on colleagues that can lead to further absence. This calculator includes pay, on-costs and cover; the other effects are real but harder to measure.

What daily pay figure should I use?

Use the average gross daily pay of the people who are absent, before tax. If you only know annual salary, divide it by the number of paid working days in a year. Add employer on-costs separately using the on-cost percentage field.

What are employer on-costs?

On-costs are what an employer pays on top of gross salary, such as employer social security or National Insurance contributions, pension contributions and benefits. The percentage varies by country and contract, so use your own figure from payroll.

How can I reduce the cost of absence?

Start by seeing where it comes from: which teams, days and absence types, and how often absence is covered with overtime. Many organisations find a few patterns drive most of the cost. TeamzMate connects attendance, schedules and payroll hours so these patterns are explained automatically.
