Most automation sales pages promise to "save you time". That's nice, but time isn't a number, and you can't take it to the bank. Here's how to turn "it'll save us loads of time" into a figure you can actually make a decision with — in about ten minutes, with a calculator.
Step 1: Price the task, not the technology
Pick one repetitive task. Then work out:
- Hours per week spent on it (be honest — track it for a week if you have to)
- Fully-loaded hourly cost of whoever does it (salary + NI + pension, divided by working hours — for a £28k employee that's roughly £17/hour, not £13)
Annual cost of the task = hours per week × hourly cost × 48
A task that eats 6 hours a week at £17/hour costs you £4,896 a year. Every year. Quietly. That's the number an automation has to beat — and most beat it comfortably.
Step 2: Add the returns nobody counts
Time saved is the obvious return, but UK businesses that automate typically find three others worth as much or more:
- Error costs. Every manual retype is a chance to invoice the wrong amount, book the wrong date, order the wrong part. One bad invoice can cost more than a month of the manual labour it replaced.
- Speed-to-lead revenue. If automation answers enquiries in two minutes instead of next morning, you win jobs you currently lose without ever knowing they existed. (More on that in the real cost of a slow reply.)
- Capacity without hiring. If your team can handle 20% more volume without a new hire, the automation just earned you most of a salary. Federation of Small Businesses research found SMEs adopting AI tools report 15–30% productivity improvements on the tasks affected.
Step 3: The payback test
Payback period = cost of automation ÷ (annual savings ÷ 12)
UK industry data suggests well-chosen first automation projects typically pay back within three to six months. My rule of thumb: if the payback is under 12 months, do it. Under 6 months, do it now. Over 24 months, the project is probably wrong — too big, too speculative, or automating something that shouldn't exist at all.
The projects that fail the test
Be suspicious of any automation where the savings are vague ("better insights", "digital readiness") rather than hours, errors or revenue. And never automate a process that's broken — you just get the wrong answer faster. Fix the process, then automate it.
