Microsoft 365 Copilot · business case calculator

What does your team’s routine work cost, and what would Copilot give back?

Add the roles that would use Copilot, their pay and the tax on top, and see the hours returned per day, week, month and year in three scenarios — against the real licence price. Then print the business case for whoever signs.

Estimates, not a guarantee: a saved hour is money only when the time is redeployed. The assumptions are visible and editable on this page; the sources are at the foot.

3 · Licence and adoption

Copilot licence ?Microsoft 365 Copilot Business is the same product at a lower price for tenants on Business Basic, Standard or Premium, up to 300 seats. Everyone else buys Microsoft 365 Copilot.
Commitment
Adoption in year one ?Not everyone uses a new tool from day one. This share of licensed people actually realises the savings, averaged over the first year. Pilots with named routines reach 70–85%; licences handed out without a plan reach 40%. %
Readiness review, one-off ?Copilot shows people what they can already open. A review of SharePoint sharing and sensitivity labels before rollout is the step that prevents the incident. Fixed price; set to 0 if you do it yourselves.

How the numbers are made

Assumptions, in the open

Where do the minutes per role come from?

From Microsoft’s Work Trend Index and Copilot usage studies, Forrester’s Total Economic Impact study of Microsoft 365 Copilot, and what we see in our own rollouts: people who use Copilot daily report saving roughly 30 minutes to two hours a day depending on how much of their day is email, meetings and documents. We set three values per role — conservative, realistic, optimistic — and you can overwrite any of them.

Why is adoption in the formula?

Because licences are bought for everyone and used by some. Studies and our experience put realised use at 40–85% in the first year, depending on whether the rollout came with a pilot and named routines. The calculator multiplies the savings by this share; the licence cost is not reduced, because it is paid regardless.

Is a saved hour really money?

Only if it is used: for more sales calls, faster close, fewer overtime hours, or a hire not made. For salaried staff the saving is capacity, not cash, until management redeploys it. That is why the case shows hours first and money second, and why the pilot measures actual usage before the company-wide purchase.

What is not in the number?

Quality: fewer errors, faster customer replies, knowledge that stays when people leave. Real, and not counted, because they cannot be measured before you start. The strategic-benefits section of the case lists them without a euro sign.
