2 Company profit
UK corporation tax has three bands: 19% up to £50,000 profit, a sliding scale between £50,000–£250,000, and 25% above that. Enter the company's annual profit and this works out which band it's in and the exact rate.

4 Presenteeism cost
Presenteeism — staff who are at work but not performing at full capacity because they're unwell — is a separate cost.
If an employee works 260 days a year but operates at only 80% capacity because of a chronic illness, stress, or anxiety, they've effectively "lost" 20% of their annual productivity:
260 working days × 20% productivity drop = 52 days lost.
The work often still gets delivered — just later, at a lower quality, or at a higher hidden cost to the business.

Glassdoor / Harris Poll, 2019
Estimated cost of losing one average employee — covering lost productivity while the role sits vacant and while a replacement ramps up, plus recruitment and training, based on the salary figure used in card 3. Typical estimates range from around half to one-and-a-half times annual salary, more toward the higher end for skilled or specialist roles. If Brighter Being helps you retain just one more person a year than you otherwise would, this is roughly what that's worth.
