What does bookkeeping really cost your practice in-house?
A salary is only part of it. Add employer National Insurance, pension, software and the hours nobody can bill, and the true cost of each productive hour is often well above the salary rate. Put in your own figures below.
These are example figures: replace them with your own. Employer National Insurance is worked out at 15% of salary above £5,000 a year (2026/27 rates), before any Employment Allowance. Pension is worked out on qualifying earnings between £6,240 and £50,270.

How it's worked out
The sums behind the number.
- Employment cost is salary plus employer National Insurance, employer pension and your other yearly costs per person.
- Productive hours are 52 five-day weeks less holiday days, at the contracted hours a day, less the unbillable share.
- True cost per productive hour is the employment cost divided by the productive hours.
- The work you'd hand over is the hours a month multiplied by that hourly cost.
It leaves out the time it takes to recruit, train and supervise, and the cost of covering absence and staff turnover, so the real figure is usually higher.
