ChatGPT costs $0 for Free, $20/month for Plus (individual), $20/user/month for Business (formerly called Team, with a 2-seat minimum), and $200/month for Pro (heavy individual usage). Enterprise is quote-only, with buyers reporting a 150-seat minimum and per-seat rates commonly landing near $60/month once negotiated.
- Business was called Team until April 2026, when OpenAI both renamed it and cut the price from $25 to $20/seat
- Business carries only a 2-seat minimum — far gentler than most enterprise SaaS seat floors
- Enterprise has no public price and, per buyer reports, a 150-seat minimum that puts the annual floor near $108,000
- Pro at $200/month exists specifically for people who'd otherwise blow through Plus's usage caps constantly
Most software gets more expensive over time, so it's genuinely unusual when OpenAI cut a price instead of raising one. In April 2026, the plan previously called ChatGPT Team became ChatGPT Business, and the per-seat rate came down from $25 to $20 a month on annual billing. Neither change was marketed loudly, which means a fair number of finance teams are still budgeting off the old name and the old number.
Below is where things actually stand: what each tier costs, what a 2-person team pays versus a 150-seat Enterprise account, and the specific spots where the advertised price and the real invoice tend to drift apart.
1. How much does ChatGPT cost?
Source: openai.com/pricing (official) + buyer-reported Enterprise terms, verified Sep 19, 2026.
Business's $20/seat rate applies to annual commitments; monthly billing runs somewhat higher. The 2-seat minimum on Business is low compared to most B2B SaaS tools on this list — it's not designed to penalize small teams the way, say, a 50-seat Enterprise floor would. Pro, at $200/month, is a separate individual-usage tier for people who need GPT-5 Pro reasoning and near-unlimited access rather than a team feature.
2. What each plan includes
| Feature | Free | Plus | Business | Enterprise |
|---|---|---|---|---|
| GPT-5 access | ✕ | ✓ | ✓ | ✓ |
| Admin console & data controls | ✕ | ✕ | ✓ | ✓ |
| No training on workspace data by default | ✕ | ✕ | ✓ | ✓ |
| SSO / SAML | ✕ | ✕ | ✕ | ✓ |
| Dedicated account team & custom contract terms | ✕ | ✕ | ✕ | ✓ |
| Unlimited/near-unlimited usage | ✕ | ✕ | ✕ | ✕ |

4. Hidden costs to budget for
| Scenario | Annual cost | Change |
|---|---|---|
| Business, 10 seats, annual | $2,400/yr | Base |
| Enterprise at reported 150-seat floor, ~$60/seat | ~$108,000/yr | Reported minimum commitment |
| API usage layered on top of a ChatGPT seat | Variable, token-metered | Entirely separate billing |
The API is a different product with different billing entirely — teams that pay for ChatGPT seats and also build on the API through OpenAI's developer platform are looking at two separate invoices, priced by token usage rather than seats, with no bundled discount for having both. On the Enterprise side, the reported 150-seat floor is the number that catches mid-size companies off guard: it's not published anywhere, so a lot of buyers only learn about it once they're already in a sales conversation.
5. How ChatGPT pricing has changed
6. Which plan should you choose?
- For casual, personal use, Free covers a lot of ground before you'll feel a real cap.
- If you're using ChatGPT daily for real work and hit Free's limits, Plus at $20/month is the obvious next step.
- For a small team of 2 or more sharing an admin console and data controls, Business at $20/seat is priced the same as Plus but adds workspace-level governance.
- If you need SSO, dedicated support, and are prepared for a large seat commitment, engage sales for Enterprise — and ask directly about the seat minimum before assuming your headcount will be quoted as-is.
7. Is it worth the price?
For an individual who relies on ChatGPT daily, Plus at $20 a month is a reasonable, uncomplicated cost. Business at the same $20/seat is arguably the better value of the two right now, given it adds admin controls and data protections for the identical price — which is part of why the April 2026 change is worth knowing about even if you're not actively shopping. Enterprise is where the calculation gets harder, purely because there's no public number to plan against and the reported seat floor changes the math for anyone under 150 people.
8. How to pay less
- Confirm you're being quoted Business, not the old Team pricing — if a reseller or internal document still says $25/seat, that's outdated as of April 2026.
- Ask directly whether the Enterprise seat minimum applies to your deal before assuming your actual headcount will be the number on the invoice.
- Separate API spend from ChatGPT seat spend in your budgeting — they're unrelated billing systems even though both come from OpenAI.
- Reassess Plus vs. Business even for a 2-person team — at equal per-seat pricing, Business's admin controls come at no premium.
Buyer reports circulating since the Enterprise tier launched put per-seat Enterprise pricing in the neighborhood of $45-75/month depending on scale and negotiation, with $60 as a commonly cited midpoint — useful context, though nothing here is an official OpenAI figure.
9. Alternatives and what they cost
| Tool | Entry price | Cheaper when |
|---|---|---|
| Claude (Anthropic) | $0-$30/user/mo (Team) | Team-tier pricing without a seat minimum fits your headcount better |
| Microsoft Copilot | $30/user/mo | Already deep in the Microsoft 365 ecosystem |
| Gemini for Workspace | $20/user/mo add-on | Already on Google Workspace and want AI bundled in |
10. The bigger picture: why ChatGPT bills drift
AI tool spend is one of the fastest-growing, least-tracked line items in most companies right now, and a rename-plus-price-change like OpenAI's April 2026 update is exactly the kind of thing that slips past a budget built six months earlier. Zapro AI is built to catch this pattern across your entire software stack, not just ChatGPT.
11. The bottom line
OpenAI's decision to cut Business pricing while renaming the plan is good news that arrived quietly enough that plenty of buyers still don't know about it. If you're budgeting for ChatGPT today, work from the current Free/Plus/Business/Pro/Enterprise structure, and specifically confirm the Enterprise seat minimum before assuming a quote will match your actual headcount.
FAQs
It was renamed to ChatGPT Business on April 2, 2026, and the price dropped from $25 to $20 per user per month on annual billing — a genuine decrease, not a rebrand with a hidden increase.
ChatGPT Plus is $20/month for one individual user, with expanded access beyond the free tier's usage limits.
Yes, but a modest one — 2 seats, which is low compared to most enterprise SaaS minimums on this list.
OpenAI doesn't publish one, but buyer reports commonly describe a roughly 150-seat minimum with annual prepayment, putting the practical floor for an Enterprise deal in the six figures annually.
The most common way is budgeting off the retired Team pricing, or running scattered individual Plus subscriptions that should have consolidated onto Business. A vendor spend platform with current pricing data is the most reliable way to catch this.
