Key takeaways
- Seat cost is predictable. Usage cost is the line to cap.
- Licence the people who will use it weekly, not the whole headcount.
- Break-even is usually a few minutes per user per week.
- All calculation happens in your browser. Nothing you enter is sent anywhere.
Most AI budgets are built backwards: someone picks a seat price, multiplies by headcount, and forgets the parts that actually move. This calculator builds the number the right way round: weekly users, a few heavy users, a usage allowance, a one-off setup, and a hard cap. It also tells you how little time each person needs to save for it to pay for itself.
Default figures reflect mainstream business-tier pricing as of October 2026: about 20 USD per standard seat on annual billing and about 100 USD for heavy-usage seats. Change them to match your provider and currency.

How the numbers work
Seats
Seats are the weekly users, not total headcount. Heavy users move to premium seats where your provider offers them, which is often cheaper than letting them hit limits or buying everyone a higher tier. Claude Team, for example, offers standard and premium seats on the same plan. See ChatGPT Business vs Claude Team.
Usage
Usage covers anything billed by consumption: automations, agents, API calls and metered credits such as those used by Copilot Studio agents. If you have none yet, put in a small placeholder rather than zero. See AI agent spending limits.
The cap
The recommended hard cap is one and a half times expected monthly usage. It is high enough not to interrupt normal work and low enough to make a runaway automation a minor event. Set it at the provider, not in a spreadsheet. See hard AI spending limits.
Break-even
The break-even figure divides your annual run rate by the loaded hourly cost of staff time, then spreads it across weekly users. It is deliberately conservative: it ignores quality gains and only counts time. In most businesses the answer is a handful of minutes a week, which is why the real question is adoption rather than price.
What the calculator leaves out
- Internal time during rollout, which shrinks the faster the rollout happens.
- Suite assistants already included in Microsoft 365 or Google Workspace, which may reduce the seats you need to buy.
- Tax and currency. Most providers price in USD. Add GST or VAT where it applies.

Frequently asked questions
How much does AI cost per employee?
Mainstream business AI assistants cost roughly 20 to 30 US dollars per user per month on annual billing as of October 2026, with heavy-usage seats around 100. Some suite assistants are included in existing Microsoft 365 or Google Workspace plans. Usage-based automation is billed separately.
How should we set our AI spending cap?
A sensible starting point is about one and a half times your expected monthly usage-based spend, set as a hard limit at the provider. Seats are fixed costs and do not need a cap, but anything billed by usage does.
How many hours does AI need to save to pay for itself?
Usually very few. At a loaded staff cost of 50 dollars an hour, a 25 dollar seat breaks even if it saves about 30 minutes a month, or around seven minutes a week. The calculator shows the figure for your own numbers.
Should we buy a seat for every employee?
No. Buy seats for people likely to use the tool weekly, add more on request, and review every quarter. Unused seats are the easiest AI cost to eliminate.
