- The UK government trial measured 26 minutes a day - 20,000 civil servants using Microsoft 365 Copilot reported that saving, about 13 working days a year.
- That figure is self-reported - the gov.uk report says so, and no published study separates content, CRM, analytics and workflow tools.
- Support chatbots use a measured 14% gain - a study of 5,179 support agents found 14% more issues resolved per hour with an AI assistant.
- Saved time is only a saving if it is reused - the calculator values hours at your hourly cost, so count them only if staff do other paid work.
AI tools save time, but the reliable evidence is more modest than vendor claims. In the UK government’s Microsoft 365 Copilot experiment, staff reported saving 26 minutes a day. In a study of 5,179 customer support agents, an AI assistant raised issues resolved per hour by 14%.
This calculator uses those two figures, values the time at your staff hourly cost and subtracts the tool subscription. Saved time only becomes a cash saving if your team spends it on other paid work.
