Microsoft Copilot’s New Pay-Per-Use Pricing: What USL, UBB and FinOps Mean for You

Microsoft is changing how Copilot is priced — and it could affect your bill. Alongside the familiar flat-rate subscription, Microsoft is rolling out usage-based billing for advanced AI features. That means three new terms every Copilot user and admin needs to understand: USL (User Subscription License), UBB (Usage-Based Billing) and FinOps. Here’s what they mean, what’s changing and what you should do now.

All three terms are widely used in Microsoft’s new Copilot announcements but you have to dig deep to find definitions. Even then, the explanations don’t exactly glisten with rectitude; here’s an example:

“FinOps for AI is a shared discipline for managing AI spend and optimizing it for business value.” – Microsoft

Until now, paying for Copilot has been on a flat-fee basis, usually a fixed yearly charge. In many cases, the fee is an add-on to an existing license, for example around US$216-360 yearly per user for volume licenses, or a Microsoft 365 plan with Copilot built-in like the consumer Premium plan.

Now Microsoft is adding a new way to get money from customers. Of course, the company doesn’t say that. They call it “Evolution of the Copilot pricing model” as if that will fool anyone.

Flat-fee Copilot remains, but now you’ll have to pay more to use advanced AI features including the newest AI models. The difference between the flat-rate and usage-based charging is where the new acronyms come in.

USL = User Subscription License

User Subscription License or USL is how we pay for Copilot now. It covers all the main AI services for a flat rate, usually paid yearly.

For consumers, the USL is part of their Microsoft 365 plan for owners of Personal, Family and especially Premium plans.

Business, Enterprise or other volume license users also have a USL, either as a Copilot add-on to their Microsoft 365 plan or a plan that includes Copilot services directly.

UBB = Usage-Based Billing

This is the relatively new part. Up to now it’s been something that admins could turn on to access some advanced Copilot features.

Usage-Based Billing is being expanded to cover more Copilot features including the newest, more powerful AI models. UBB is charged based on use of those extra AI services.

Later in 2026, Microsoft 365 consumer plans will also have the UBB option to access more advanced Copilot features.

Pricing of UBB features hasn’t been announced yet.

Don’t panic

User Based Billing is defaulted off for all organizations. IT Admins have to turn UBB on and can limit its use.

There are options to restrict which users in an organization can access UBB chargeable features. Also limits on the amount that can be spent per user, per group of users or organization as a whole. Any sensible IT management will set limits immediately to avoid an unexpectedly high bill.

FinOps = managing User Based Billing

Related to UBB is another new Microsoft buzzword, FinOps. Or in English, Financial Operations.

FinOps for AI is Microsoft’s name for the tools and habits that let an organization track, cap and justify what it spends on the pay-per-use (UBB) parts of Copilot.

FinOps is AI technology to manage UBB, the fuel gauge, the budget, and the kill switch for the metered part of Copilot.

The term itself comes from cloud computing, where “FinOps” means getting finance, IT and business teams to jointly manage spending that goes up and down with usage. Microsoft is applying the same idea to AI.

What changes for Copilot customers

Very little will change. Everyday Copilot stays covered by your existing per user license, with no meter running on each prompt.

What users on a Microsoft 365 plan with Copilot will notice:

You may see features you can’t use. Microsoft deliberately shows the metered features in the product, but for business customers they stay switched off until an admin creates a spending policy. If Cowork or a frontier model is grayed out or asks you to request access, that’s why.
You’ll get a credit balance. Once enabled, you can see your credits used, credits remaining and usage history right inside Copilot, with notifications as you approach your limit.
Heavy users may hit a fair use ceiling. Microsoft says most people won’t. If you do, you get a warning first, then a choice: switch the model picker to Auto (free) or move to paid credits. Microsoft’s own line is that hitting a limit “is not hitting a wall.” True, but the way over the wall costs money.

More on Copilot Changes and Microsoft 365 Costs

The Copilot app itself is also changing. Microsoft is merging its two separate Copilot apps into one — find out what changes on your PC and phone and why the Copilot merge eats your OneDrive space and cuts features.

If you’re trying to get more out of Copilot right now, it’s worth knowing which AI model to choose. We’ve tested that in Word, Excel and PowerPoint, and there’s also Grok AI in Microsoft 365 if your admin has enabled it.

Copilot’s access tiers matter too. Before UBB rolls out more broadly, make sure you understand the current Standard vs Priority Access in Copilot — the distinction will become even more important once usage-based billing is live.

The bigger picture is rising Microsoft 365 costs. Business subscribers already saw a Microsoft 365 price increase in 2026, and Microsoft now has 95 million subscribers with rising bills. UBB adds another layer to those costs, especially for organizations that were already budgeting carefully.
