Copilot Credits: What Microsoft AI Agents Cost

Copilot credits are the metered currency Microsoft now uses for agent work: Copilot Studio agents, Copilot Cowork, Code, Autopilot and frontier models all draw on them, while the Microsoft 365 Copilot seat covers everyday Chat and Office use. In Australia a prepaid pack of 25,000 credits lists at A$299.30 a month ex GST, and pay-as-you-go is US$0.01 per credit. A small business running two modest agents can sit inside one pack, but a single change of model can more than triple the bill, so set a spending limit before anyone switches an agent on.

TL;DR: Under the model Microsoft announced on 25 September 2026, the Copilot seat pays for Chat and the Office apps, while agentic work is billed in Copilot Credits from packs, a pre-purchase plan or Azure pay-as-you-go. Cap spend in both admin centres, then pilot one agent and measure before you scale.

What changed on 25 September 2026

Seat prices and break-even maths are in Microsoft 365 Copilot for Business: AU Cost. This piece is about what sits outside the seat.

On 25 September, Microsoft’s announcement of the new Copilot drew a line through the product. The user subscription licence covers Copilot in Chat and across Word, Excel, PowerPoint, Outlook and Teams, plus model selection. Cowork, Code and Autopilot, which Microsoft calls “new long-running agentic capabilities”, run on usage-based billing, as do frontier models. Microsoft’s pricing model post adds two details that matter for budgeting: a seat is required for the usage-billed Copilot features such as Cowork, and for enterprise customers those features stay off until an admin creates a spending policy. Reseller-sold Copilot Business is about to work differently, as covered below.

Copilot Studio agents were already metered this way. The usage-based billing overview now puts them in one tenant-wide pool with Cowork, advanced SharePoint and OneDrive work, Work IQ APIs and the Teams Phone Agent. One pool is convenient, and it lets one enthusiastic team drain what another was counting on.

How Copilot credits are priced in Australia

There are three ways to pay, and they can be layered. Microsoft bills prepaid packs first, then a pre-purchase plan, then pay-as-you-go.

The pack works out at US$0.008 a credit, against US$0.01 on pay-as-you-go. At these list prices a pack costs the same as 20,000 pay-as-you-go credits, so it only saves money once you reliably use more than that each month.

The seat stays a separate line: Microsoft 365 Copilot Business lists at A$31.40 per user per month on an annual plan ex GST, or a promotional A$26.91 for eligible customers until 31 December 2026, per Microsoft’s Australian Copilot Business page.

What actually burns credits

Microsoft publishes a Copilot Studio rate card on its billing rates page. The rates that matter most:

The last row is where budgets go wrong. When a reasoning model runs an agent, Microsoft charges for the tokens it processes, and one reply can involve several model calls. Microsoft’s own example is a support agent whose single follow-up answer costs 141 credits in reasoning charges alone in a running conversation, and 461 when the same question opens a new one. The ordinary feature rates come on top.

One exemption helps. When a staff member with a Microsoft 365 Copilot seat uses an internal agent under their own identity, the standard agent features are included at no charge, within fair-use limits. That inclusion doesn’t cover agents that run on their own from a trigger, or computer-using agents.

Cowork is easier to estimate per task. The Copilot Credits Guide gives rough planning ranges: 100 to 300 credits for a light task such as a weekly status update, 300 to 700 for a medium task such as a meeting briefing pack, and more than 700 for heavy analysis. Five staff running two light Cowork tasks a day at 200 credits each would use about 42,000 credits over 21 working days, which is US$420 a month on pay-as-you-go. The five Copilot Business seats those people need cost A$157 a month ex GST at list, so the meter can easily outrun the licence.

A worked estimate for a 20-person business

This example is illustrative and the assumptions are ours. Take a 20-person professional services firm on Microsoft 365 Business Standard with no Copilot seats, running two Copilot Studio agents on a standard (non-reasoning) model.

Agent A, a staff policy and IT help agent grounded in SharePoint. Each question uses one generative answer (2 credits) plus tenant graph grounding (10 credits), so 12 credits. Twenty staff asking three questions a working day over 21 days is 1,260 questions, or 15,120 credits.

Agent B, an autonomous supplier-invoice intake agent triggered by each incoming invoice email. Each run takes four agent actions (20 credits) and one generative answer (2 credits), so 22 credits. At 400 invoices a month that is 8,800 credits.

Microsoft’s own pack prices imply about A$1.50 per US$1 (A$299.30 against US$200), so US$239.20 is roughly A$358. That is an illustration, not a list price.

The base case fits one pack with only 1,080 credits to spare. A busy month tips into pay-as-you-go if a meter is connected; without one, Microsoft tolerates some overage and then blocks the agents once the tenant hits 125% of its prepaid capacity. The reasoning-model row matters more: nobody added a user, one setting changed, and the monthly cost rose more than threefold.

How to cap the spend before you switch agents on

No agent should go live in a tenant that doesn’t have a hard limit. The controls are split across two admin centres.

In the Microsoft 365 admin center (Copilot, then Cost Management), the first spending policy you activate offers a choice between “Don’t limit monthly spending” and “Limit monthly spending”, as described in Microsoft’s setup guide. Choose the limit. Set a per-user monthly limit as well (Microsoft’s current minimum is 2,000 credits per user), add alert recipients, and turn off “Auto-apply new services”. It is on by default, which means services Microsoft adds later join your policy without anyone deciding they should.

In the Power Platform admin center, under Licensing, Copilot Studio and then Manage Agents, you can set a monthly limit per agent with notifications and a hard stop that turns the agent off. Two caveats from Microsoft’s documentation: limits aren’t applied instantly, and an agent’s limit doesn’t stop the agent flows it calls, which are metered separately.

Watch your reseller too. Microsoft’s Partner Center announcement, updated on 3 November, says new Copilot Business purchases through Cloud Solution Providers will switch usage-based billing on by default, for the tenant’s existing Copilot Business licences too, with a default limit of 4,000 credits per user per month. Rollout is planned to begin between January and March 2027, Australia included. For 20 Copilot Business users, that default allows 80,000 credits, or US$800, a month before anyone has asked for it.

If an agent makes or informs decisions that significantly affect people, such as screening applicants, and uses their personal information to do it, APP 1.7 requires APP entities to say so in their privacy policy from 10 December 2026, as the OAIC explains. Our AI agent security checklist covers what an agent should be allowed to touch.

Pilot, measure, then scale

Your own consumption report beats any estimator. We’d run one agent for four to six weeks with a pay-as-you-go limit set at roughly double the estimate, then download the detailed consumption report from the Power Platform admin center and group billed credits by AI feature and by model. Buy packs only once usage reliably clears 20,000 credits a month.

What we see go wrong is the reverse: packs bought on enthusiasm, a reasoning model picked because it tested well, and nobody watching the meter until the Azure invoice lands. Our 90-day AI pilot guide shows how to define success first.

The bottom line on Copilot credits

Copilot credits make Microsoft’s agents affordable at small-business volumes, provided you know your volumes. In our illustration, two well-built agents for a 20-person firm came in at around A$300 a month, and the same agents on the wrong model cost several times that. Cap the spend first. After that, let one agent’s consumption report, not an estimator, decide what you buy.

If you’d like a second pair of eyes on it, the AI Quick-Win Audit is a $2,950 flat, ten-business-day engagement.
