A subscription rate is a starting point for a budget, not the full cost of an AI rollout. Separate the seats you expect to use, the commitment you are making, and the staff time needed to turn access into useful work. That gives finance a clearer decision than a single per-user figure.
Published standard-seat rates
OpenAI lists a ChatGPT Business standard seat at $20 per month billed annually, or $25 billed monthly. The business pricing page also describes flexible seat types and purchasing credits for more access. Confirm your checkout currency, eligibility, included usage, taxes, and terms before buying.

A ten-seat illustration
| Billing option | Ten seats | 12-month seat total |
|---|---|---|
| Annual, $20 equivalent per month | $200/month equivalent | $2,400 |
| Monthly, $25 per month | $250/month | $3,000 |
This is arithmetic for ten standard seats held for a full year at the listed rates. It excludes taxes, additional usage, and other services. The annual option is $600 lower in this scenario, but monthly billing can make an uncertain pilot easier to evaluate before a longer commitment.
Add the internal cost
Suppose onboarding takes two hours for each of ten employees. At an illustrative loaded labor cost of $50 an hour, that is $1,000 of staff time. Add administrator setup, workflow documentation, and review effort separately. These are planning assumptions, not vendor charges.
Use your own labor figures and avoid counting every saved minute as cash returned to the business. Time only becomes valuable when people can use it for useful work, and it does not automatically reduce payroll or increase sales.
Budget by active use
List which employees have recurring tasks that justify access. During the pilot, distinguish people who opened the tool once from people who completed work with it. Review unused access against the terms of your billing arrangement before the next renewal.
Make the decision measurable
Choose one output, such as an approved proposal draft, and record its full preparation and review time. Compare the cost per acceptable output with the existing process. If the tool improves quality rather than speed, document that benefit separately instead of forcing it into a time-saving claim.
A sound budget leaves room for setup and acknowledges uncertain adoption. Start with evidence from a small group, then expand the seat count when the work supports it.
A break-even calculation with honest assumptions
Using the ten-seat annual scenario, allocate $200 a month to subscription cost and spread the illustrative $1,000 onboarding effort over twelve months, or about $83.33 a month. Before other costs, that is about $283.33 a month. At an assumed $50 an hour, the team would need about 5.67 hours of useful time savings per month to match that modeled cost.
Across ten employees, that is about 34 minutes each per month. It is a planning threshold, not a prediction that the software will save that time. Add administrative work, extra usage, and any additional services to your own calculation. Do not count the same saved time twice across separate tasks.
Test the adoption sensitivity
| Regular users among 10 paid seats | Annual-plan seat cost per active user per month |
|---|---|
| 10 | $20 |
| 5 | $40 |
| 2 | $100 |
This table divides the same $200 monthly-equivalent seat budget by active users. It does not change the vendor's rate. It makes the effect of unused seats visible and gives the project owner a reason to monitor adoption before renewal.
Keep a renewal memo
Record the contracted seat types, billing cycle, renewal date, cancellation terms, and owner of the account. Include the results of the pilot and any change in the tasks employees actually perform. Check the current official price again before renewing; a saved screenshot from the original purchase is not a current quote.
Finally, keep a subscription decision separate from an integration project. If your business wants custom automated workflows, obtain a separate cost estimate covering the required services, implementation, and ongoing operation. A workspace budget should not silently become the budget for a broader software project.
