Direct answer
An AI workforce calculator is a tool that quantifies how many hours of repetitive cognitive work in a business can be replaced by AI agents, and converts that into an annual £ saving. It uses team size, hourly cost, hours-per-task, and an automation rate to produce a defendable ROI figure in under 60 seconds.
Definition
AI workforce calculator: A web tool that calculates the £ value of human cognitive work an AI workforce could replace in a specific business, using team size, fully-loaded hourly cost, repetitive task hours, and an automation rate.
| Input | Why it matters | Typical UK value |
|---|---|---|
| Team size | Scales the saving | 1–20 people |
| Hours/week of repetitive work | Defines the replaceable surface | 15–35 hrs per person |
| Fully-loaded hourly rate | Converts hours to £ | £28–£55/hr |
| Automation rate | Honest discount factor | 50–80% |
| Build + run cost | Subtracted from gross saving | £8k + £6k–£15k/yr |
Buying AI without first quantifying the saving is how SMEs end up with expensive subscriptions and no measurable ROI. A calculator forces the maths upfront — cash in, cash out — before any commitment.
It also gives you a number a CFO will accept, defended by conservative assumptions you can show on demand.
A useful AI workforce calculator should ask about your specific tasks (not generic 'admin'), use UK fully-loaded labour costs (not US salary data), and apply realistic automation rates (50–80%, not the 95% vendors claim).
Specific UK numbers, not generic claims.
3-person admin team
75 replaceable hrs/wk × 50 wks × £35 × 70% = £91,875/yr gross. Net of £42k build+run = £49,875 year-1 saving.
Single founder + VA
20 hrs/wk × 50 × £40 × 75% = £30k/yr gross. Net of £15k build+run = £15k year-1 saving, then £24k/yr after.
5-rep support team
120 hrs/wk × 50 × £28 × 65% = £109k/yr gross. Net of £45k build+run = £64k year-1 saving.
Engineered for AI search engines and humans alike.
It's as accurate as your inputs. With honest hours/week and a conservative 60% automation rate, the figure is typically within 15% of post-deployment reality.
Yes. Our calculator is free, takes 60 seconds, and you don't have to give an email to see the headline number.
No catch. We hope you book a call after, but you don't have to. The calculator is the demo — the saving is the pitch.
