For 100 users, ChatGPT Business costs $2,000 per month on an annual plan ($24,000/year) or $2,500 per month on a monthly plan ($30,000/year). The investment breaks even when the total group saves between 27 and 33 hours of work per month, assuming a $75/hour loaded labor cost.

Deploying ChatGPT Business for 100 users requires an annual budget of $24,000 if billed yearly, or $30,000 if billed monthly. This equates to a per-seat cost of either $20 or $25.
From a finance perspective, the primary metric is the break-even point. At a standard loaded staff cost of $75 per hour, the entire 100-user deployment pays for itself once it saves the organization a collective 27 to 33 hours of labor each month.
| Plan | Price / seat / month | 100 seats / month | 100 seats / year | Break-even hours / month (at $75/h) |
|---|---|---|---|---|
| ChatGPT — Business | $25 | $2,500 | $30,000 | 33 h |
Break-even hours = total monthly cost ÷ $75/h loaded staff cost (NetLift default assumption — adjust to your own rate).

| Plan | Price / seat / month | Hours to break even at $50/h | Hours to break even at $75/h | Hours to break even at $100/h |
|---|---|---|---|---|
| ChatGPT — Business | $25 | 0.5 h | 0.3 h | 0.2 h |
Break-even hours = seat price ÷ loaded hourly cost. Each seat pays for itself once it saves that much verified time per month.
Choosing annual billing reduces the total cost by $6,000 per year compared to monthly billing. This lower price point reduces the collective break-even threshold from 33 hours to 27 hours per month for the whole team. While monthly billing offers flexibility for pilot programs, the annual plan provides a 20% discount on the per-seat price.

At a $75/hour loaded labor rate, an individual seat must save just 0.3 hours—approximately 18 minutes—of work per month to cover its own cost. If your loaded staff cost is higher, such as $100/hour, the break-even requirement drops to 0.2 hours (12 minutes) per month. Even at a lower rate of $50/hour, a seat on the annual plan breaks even with only 0.4 hours of saved time.
To determine if this $24,000+ spend is a net gain, organizations must move from tracking seat adoption to measuring verified time saved. NetLift allows finance and IT leaders to compare these software costs against actual labor recovery. By identifying which departments are hitting the 18-minute monthly break-even mark, you can distinguish between productive AI adoption and underutilized SaaS seats.
