Free Hidden Admin Cost Calculator
See the true annual cost of quoting, invoicing, chasing and scheduling, the unpaid hours that quietly eat your earning time.
Every hour you spend on paperwork is an hour you're not on the tools earning. Enter your trade, weekly admin hours and day rate, and this report converts that lost time into a real yearly figure, then shows you which admin jobs to cut or automate first so you get those billable hours back.

Get startedHow to use the Hidden Admin Cost Calculator
- 1Pick your trade so the report frames the numbers in terms you recognise.
- 2Estimate your weekly admin hours: quoting, invoicing, chasing payment, booking jobs, ordering materials, answering messages in the evening all count.
- 3Enter your day rate. We convert it to an hourly value so your admin time is priced at what you'd otherwise earn on the tools.
- 4Get your report. It shows the true annual cost of your admin and ranks which tasks are worth cutting or automating first.
- 5Use the figure to judge whether tools or help that free up those hours would pay for themselves, and usually they do many times over.
How the Hidden Admin Cost Calculator works
Admin doesn't show up on an invoice, so it feels free, but every hour spent on it is an hour you couldn't bill. Price it at what your on-the-tools time is worth and the real cost becomes obvious.
- 8 hours of admin a week × 52 weeks = 416 hours a year.
- A £350 day rate over an 8-hour day is about £44 an hour of earning power.
- 416 hours × £44 = roughly £18,300 of billable time lost to admin every year.
That's the opportunity cost, not cash out the door, but it's real: those are hours you could have sold. The calculator uses your own figures, and even halving the estimate, the number is usually thousands of pounds a year.
