What is poor mental health costing your organisation?

Three figures you already know. National benchmarks do the rest.

Number of employees

Average salary

£

Average sick days per employee

UK average is 9.4 days (CIPD, 2025)

Direct cost of absence

£416,000

Calculated from the figures you entered.

Estimated total cost of poor mental health

£375,000

Absence, presenteeism and turnover combined. Presenteeism is usually the largest share and never appears on an absence report.

Investment justified to recover a tenth of it

£7,979

At Deloitte's average return of £4.70 for every £1 invested.

These are estimates, and we would rather say so. The absence figure uses your inputs. The total cost figure divides Deloitte's £51 billion national estimate across the UK workforce — it is a benchmark, not a measurement of your organisation. Your actual position depends on which parts of your working environment are generating pressure, and that is not something a calculator can tell you.
