Copilot Cowork Pricing Explained: Copilot Credits, PayGo, and What It Really Costs
Microsoft made Copilot Cowork generally available on June 16, 2026. The biggest change from the Frontier preview is how you pay for it. Instead of a flat per-seat add-on, Copilot Cowork uses usage-based billing measured in Copilot Credits. That makes the cost flexible, but also harder to predict if you do not understand what drives it. This guide breaks it down.
Quick version: you need a Microsoft 365 Copilot license to use Cowork, and on top of that you pay per task in Copilot Credits at $0.01 per credit. It is turned off by default, and admins set spending limits before anyone can run a task.
What you need before you can pay anything
Copilot Cowork is not a standalone product. To use it, a user first needs a Microsoft 365 Copilot User Subscription License (USL), the same license that powers Copilot across Word, Excel, Teams, and Outlook. Cowork then sits on top of that as a metered capability.
Crucially, Cowork is disabled by default at GA. An admin has to turn it on and set spending limits before any task will run. So even with the right license, nobody is racking up charges until IT explicitly opts in.
How the billing works: Copilot Credits
Every Cowork task consumes Copilot Credits. One credit costs $0.01 under pay-as-you-go pricing. The number of credits a task uses depends on four things:
- Model use - which model runs the task and how much it reasons.
- Context retrieval - how much of your data (files, emails, chats) it has to pull in and ground against.
- Tool calls - how many actions it takes across apps and plugins.
- Runtime - how long the task runs end to end.
In other words, a quick one-step task is cheap, and a long, multi-source, multi-output project costs more. That is the whole point of usage-based pricing: you pay in proportion to the work done.
Worth knowing: Copilot Credits are a shared Microsoft currency. The same credits also power other usage-based services, such as the Work IQ API, not just Cowork.
Light, Medium, and Heavy tasks
Microsoft groups tasks into three rough tiers. The exact credit cost of any given task varies, and Microsoft has said a per-task price display is coming soon, but the tiers give you a mental model for relative cost:
| Tier | What it looks like | Relative cost |
|---|---|---|
| Light | Minimal sources, limited reasoning, one output or fewer | Lowest |
| Medium | Multiple sources, structured reasoning, two or more outputs | Moderate |
| Heavy | Broad aggregation, deep reasoning, many outputs | Highest |
A "sort my inbox from the last 24 hours" request is a light task. "Aggregate these twelve reports, build a financial model, and produce a deck plus a summary memo" is a heavy one.

PayGo vs prepaid (P3)
There are two ways to pay for credits:
- Pay-as-you-go (PayGo) - billed per credit as you consume them, at $0.01 each. Best for variable or unpredictable usage.
- Prepaid (P3) - buy a block of credits up front. Useful for budgeting and committing spend in advance.
- Existing capacity - if your organization already has allocated capacity, Cowork usage can draw from it.
For billing at scale, admins can connect the setup to an Azure subscription.
Which models run your tasks (and why it matters for cost)
At GA, Copilot Cowork runs on Anthropic Opus 4.8 and Sonnet 4.6. A cost-optimized model called Cowork 1 is launching in the coming weeks, and Frontier customers can also access GPT-5.5. Because model choice affects credit consumption, a model picker lets you trade capability for cost: route routine work to a cheaper model and save the heavyweight model for hard problems.
How admins keep spend under control
Admins manage all of this from the Cost Management dashboard in the Microsoft 365 admin center, which comes with guardrails so a single team cannot blow the budget:
- Spending policies and limits at the tenant, group, or user level, including hard caps to prevent overspending.
- Customizable usage alerts and budgets as you approach a limit.
- User-initiated credit requests when someone needs more.
- An Overview tab for real-time spend and remaining capacity, and a Consumption tab to drill into usage by user, group, service, or agent.
The grace period (if you were in the preview)
Tenants that had Frontier users between March 30 and June 16, 2026 get a billing grace period until July 1, 2026. If that is you, it is worth confirming the exact cutover date with your admin so the first invoice is not a surprise.
How does it compare to Claude Cowork?
In its announcement, Microsoft claimed Copilot Cowork averaged 30 to 40 percent cheaper than Claude Cowork with the Microsoft 365 connector in its own testing. That is a vendor benchmark, not an independent one, so treat it as a directional claim rather than a guarantee. The real cost for your organization depends on your task mix, your model choices, and how much grounding data each task pulls in.
The bottom line
Copilot Cowork pricing rewards deliberate use. Keep routine tasks light, lean on the cheaper models for everyday work, set sensible spending limits, and watch the usage reports for the first few weeks to learn what your real per-task costs look like. Used that way, the pay-per-task model can be cheaper than a flat seat fee, because you only pay when Cowork actually does work.
Frequently asked questions
Is there a free trial for Copilot Cowork?
There is no standalone free trial. Copilot Cowork requires a Microsoft 365 Copilot license, and usage is billed per task in Copilot Credits. Tenants that took part in the Frontier preview received a billing grace period until July 1, 2026. To test it cheaply, an admin can enable it with a small spending limit and start with light tasks.
What is a Copilot Credit?
A Copilot Credit is the unit Microsoft uses to meter Copilot Cowork usage. One credit costs $0.01 under pay-as-you-go pricing. Each task consumes a number of credits based on model use, context retrieval, tool calls, and runtime.
Do I need a Microsoft 365 Copilot license to use Cowork?
Yes. Copilot Cowork requires a Microsoft 365 Copilot User Subscription License. The usage-based Copilot Credit charges are billed in addition to that license.
Is Copilot Cowork turned on automatically?
No. At general availability, Copilot Cowork is disabled by default. An admin must enable it and set spending limits before anyone in the organization can run a task.
Is Copilot Cowork cheaper than Claude Cowork?
Microsoft says its own testing found Copilot Cowork averaged 30 to 40 percent cheaper than Claude Cowork with the Microsoft 365 connector. That is a vendor benchmark, so actual savings depend on your task mix and model choices.
