Statutory allowances in the UK are higher than in the US, and in the UK for instance you would add:
- 12.5% national insurance + apprentice levy
- 3-4% pension
- 10% of days as holidays
- 5% of days as sick / other leave (dependent on amount taken in reality)
- 2% payroll fees / other
Note, this excludes training and equipment/office space.
When a company is undergoing fast growth, the return from one month of work can be startlingly huge. Every tool that enables better use of time is a multiplier on the income generated by that employee.
Also note, “sir” seems snarky to me at best and insulting at worst. Are you even answering a guy?
