What is the repeated admin costing you?
List the jobs your business does over and over, say how long each one takes and how often it happens, and this puts a number on the week that keeps disappearing.
How this works it out
-
Minutes, times how often
Each job is minutes multiplied by times a week.
-
Hours a week
Those add up to hours a week.
-
Hours a month, and a year
Hours a week becomes hours a month by multiplying by 46.4 working weeks and dividing by 12, and hours a year by multiplying by 46.4.
-
The cost
The cost is those hours multiplied by the hourly figure you set.
The working year is 46.4 weeks because statutory paid holiday is 5.6 weeks. Sickness, training and the general friction of a real week are left out, which makes the result conservative on purpose.
If you use the salary box, the hourly figure is the salary divided by your weekly hours multiplied by 46.4 weeks. Our full workings are on the methodology page.
What ticking employer costs adds to that hourly figure
With employer costs ticked it also adds National Insurance at 15 per cent of pay above £5,000, and the minimum workplace pension of 3 per cent of the pay between £6,240 and £50,270.
It does not try to guess whether your Employment Allowance is already used up elsewhere, which would lower the National Insurance on one more hire.
Questions people ask
- What counts as admin for this?
- Any job the business repeats to a pattern: the same question answered again, the same form filled in, the same figures moved from one place to another. If the work is different every time and needs someone to decide something, it is not what this tool is counting.
- What hourly rate should I use?
- Use the cost of whoever actually does the job, not your own charge out rate. The tool can work it out from a salary, and it will add employer National Insurance and the minimum workplace pension if you ask it to.
- Does this tell me what I would save?
- No, and no tool honestly can before someone has looked at your week. This counts what the repeated work costs you now. How much of it could run without a person depends on how consistent each job is and how much judgement it needs.
- Is anything I type here stored?
- Your figures are not. The sums run in your browser and the numbers you type are never sent to us. We do count that a tool was used, with no figures attached, so we know which tools are worth keeping. The one thing that reaches us is the summary on the button at the end, and only if you press it, because that button puts the same summary into the audit form in front of you, where you can edit or delete it before sending anything. No cookies, no tracking, nothing stored on your device.

This is an estimate. The audit is the count.
A calculator works from what you typed. The free audit works from your actual week: every repeated job, ranked by the hours it eats, with a map of the five worth doing first. It costs nothing and you keep the lot.
