Microsoft Copilot, explained

“Copilot” is several different things, some free and some paid. Here’s what each one does for a small business, and what it costs.

Prices and features last verified . US prices, before tax. Microsoft can change them.

Copilot Cowork

Pay per task

Needs a paid seat. Every task is billed in Copilot Credits at $0.01 each.

Your company files

Inside Word, Excel, Outlook, Teams
Yes. It creates files, drafts emails, books meetings and files documents, and asks you to approve sensitive steps like sending an email.
Microsoft agents (Researcher, Analyst)
Through the paid seat.
Does multi-step work for you
Yes, including on a schedule, like a Monday-morning briefing.

Good for: Repeated multi-step chores. You set a monthly spending cap, so there are no surprise bills.

What a Cowork task costs

Microsoft doesn’t publish an exact price per task; it depends on how long the task runs. Rough estimates from Microsoft’s own examples:

A light task every week comes to a few dollars a month. You can cap spending per person or for the whole business.

Cowork needs a paid Copilot seat. Microsoft says Copilot Business has the same capabilities as its enterprise seat but hasn’t yet said explicitly that it includes Cowork, and an admin has to switch Cowork on.

Which one do I need?

Staff without a paid seat can still use company agents your team sets up, paying per answer: about $0.12 for an answer that searches your company files.
