Free admin hours calculator for personal trainers, therapists, beauty pros, and other solo service business owners. Enter how you spend your working week and find out exactly how many hours you're losing to unpaid admin, what that's costing you in income, and where automation would give you the most time back.
Aasure automates the bookings, invoicing, reminders, and client messages that are eating your week — so every working hour becomes a billable one.
Join the WaitlistMost solo and small-team service businesses lose somewhere between five and fifteen hours a week to admin. Invoices. Confirmations. DMs. Chasing deposits. Setting up next week's calendar. None of it is the work you trained for, and almost none of it is paid.
This calculator turns that drift into a number — what those admin hours are actually worth at your hourly rate, and what reclaiming half of them would do to your weekly take-home. The honest answer is usually larger than expected: ten admin hours a week at £60/hour is £31,200 a year, even before counting the cost of context-switching.
The fix isn't more discipline. It's fewer tabs. Most service businesses can move 60-70% of their weekly admin into a single platform that handles bookings, payments, reminders, follow-ups, and client records together. The calculator below shows the upside, in pounds and hours, of doing exactly that.
Five to fifteen hours a week is typical for solo operators. The biggest chunks tend to be invoicing, client comms, scheduling adjustments, and follow-ups. Established practices with the right tooling often run at three to five.
It is your normal hourly rate — because that hour could have been billable work. If you charge £60 a session and spend ten hours a week on admin, that is £600 a week in opportunity cost, every week, before you count tiredness or context-switching.
Yes — most service businesses cut weekly admin in half once bookings, reminders, payments, and client records sit in one place. The 'in one place' part is the key change; using five tools, even great ones, recreates most of the original admin.
