How is Microsoft Copilot ROI calculated?
ROI is the productivity value Copilot creates, minus what the licences cost, divided by that licence cost. Productivity value is the time each user saves per day × their fully-loaded hourly cost × licensed users × working days per year. The variable most calculators quietly ignore is adoption — time savings only appear for people who actually change how they work.
How much time does Copilot actually save?
Microsoft's own WorkLab research puts it at around 14 minutes per active user per day. Independent studies land anywhere from roughly 10 to 30 minutes depending on role, task mix and how well adoption is driven. We default the slider to 14 so your starting estimate is conservative and defensible.
What's a "fully-loaded" hourly cost?
It's not just salary — it's salary plus benefits, tax, overhead and the cost of the tools and space around each employee. It's the true cost of one hour of that person's time, and it's the right figure to value time savings against. A useful rule of thumb is roughly 1.25–1.4× base salary.
Why do you show two ROI scenarios instead of one?
Because a single number is misleading. The headline ROI assumes everyone uses Copilot well — which almost never happens on its own. Showing the unmanaged vs. structured-adoption range is simply more honest, and it points at the real work: getting people to use what you've already bought.
Is Microsoft Copilot worth it?
For most knowledge-worker teams, yes — a fully-loaded hour costs far more than a monthly licence, so the maths works even at modest time savings. The sharper question is how much of that ROI you'll realise, which comes down to adoption. That's the part we help with.
Can you help us hit the higher-adoption number?
That's exactly what Copilot Experts does. We run adoption-led Copilot rollouts — role-based enablement, prompt libraries, change management and usage analytics — designed to move your active-user rate from the unmanaged band toward the structured-program band. Book a review and we'll map it to your numbers.
