ChatGPT Pricing (2026): Every Plan from Free to $500 Pro, and What Each One Runs Out Of

The short answer

As of October 19, 2026, ChatGPT costs $0 on Free, $8 a month on Go, $20 on Plus, and $100, $200 or $500 a month on Pro. ChatGPT Business is $20 per seat per month billed yearly or $25 billed monthly, with a 2-seat minimum, and Premium Business seats are $100 or $125. Enterprise and Edu are quoted by sales.

Here's the part the price list hides: OpenAI lists everyday text chats as unlimited on every one of those plans, Free included. You're not paying for more chatting. You're paying for better models, more room per conversation, and agent work (Codex, ChatGPT Work, scheduled tasks) that actually runs out. Below is every plan on one table, what each one runs out of, and what a solo owner, a 10-person team and a heavy user really pay in a year.

Every ChatGPT plan on one table

Two discounted routes sit off the main ladder. Verified nonprofits pay $8 a Standard Business seat billed yearly ($10 monthly), and larger ones can get up to 75% off Enterprise. Verified U.S. K-12 teachers and staff get ChatGPT for Teachers free through June 2028. One heads-up on that last one: OpenAI's own pricing FAQ still says June 2027, while the Teachers plan page says June 2028. The plan page is the newer of the two.

What each plan actually runs out of

Since chat itself is unlimited everywhere, the real differences are three limits, and they're the ones to check against how your team works:

• Which models you get. Free and Go stop at GPT-6 Luna. GPT-6.1 Sol, GPT-6 Astra and GPT-6 Sol start at Plus, and Pro gets "expanded" access to all of them. If the work is reasoning-heavy (contracts, financial models, long reports), Free and Go aren't the plan, whatever the chat count says.
• How much fits in one conversation. The everyday model's window is 27K on Free (about 12 pages of input), 54K on Go and Plus (about 40 pages), and 128K on Pro (about 250 pages). The reasoning models get 256K on Go and Plus (about 320 pages) and 400K on Pro (about 680 pages). A 60-page policy manual fits on Plus only in the reasoning model, and on Pro in either.
• Agent work per 5 hours. In ChatGPT Work and Codex, Plus and Standard Business seats get the same published estimates: 15 to 160 local messages per 5 hours on GPT-6.1 Sol, 5 to 45 on GPT-6 Astra, and 350 to 3,000 on GPT-6 Luna. Pro has no five-hour limit right now, and neither do Premium Business seats, which carry 5x the usage of a Standard seat. The full breakdown, including what happens when you hit the wall, is in ChatGPT usage limits.

The "same $20" trap: Plus vs Business for a small team

Plus and a Business Standard seat both say $20, and that's where most small teams stop reading. They're not the same $20.

The Business $20 is the yearly-billing price, and Business needs at least two seats. So the cheapest Business workspace you can buy is $40 a month, $480 a year, against $240 for one Plus subscription. Paid monthly, Business is $25 a seat, $600 a year for two. For a solo owner, the second seat is the price of having a business workspace at all.

Here's what that money buys. Business doesn't train on your data by default; on Plus, training is on unless each person opts out. Business adds an admin console, SAML SSO and domain verification; Plus has none of those, so when someone leaves, their chats and files leave with their personal account. On agent work, a Standard seat gets the same published 5-hour estimates as Plus, so you're not buying more usage per person. If client or employee information goes into ChatGPT, that's the line where Plus stops being the cheap option and starts being the risky one. The seat-by-seat detail is in ChatGPT Business pricing.

Worked example: a 10-person team for a year

The first two rows are the point. Ten Plus subscriptions and ten yearly Business seats cost exactly the same $2,400. The only way Plus comes out cheaper is if you'd otherwise pay Business month to month, and even then the gap is $600 a year for admin control, SSO and your data staying out of training. Expensing ten personal subscriptions isn't saving money. It's paying the same for less control.

The Premium row is for the two people who'll live in Codex or ChatGPT Work all day. Giving them Premium instead of Standard adds $1,920 a year, and in return they get 5x the usage and no 5-hour wall. Seat types can be mixed in one workspace, so you don't have to put the whole team on the expensive tier to cover your two heaviest users.

Worked example: one heavy user, Pro or Premium?

If you're the one person running out of usage, there are two ways to buy more of it, and they're priced closer than they look:

• Pro 100: $100 a month, billed monthly only (OpenAI doesn't offer annual Pro), so $1,200 a year. No five-hour limit. Personal account: no admin console, no SSO.
• Business Premium: $100 a seat billed yearly, but the 2-seat minimum means one Premium plus one Standard seat, $120 a month or $1,440 a year. No 5-hour limit and 5x a Standard seat's usage, inside a business workspace that doesn't train on your data by default.

So for $240 more a year, the business version adds a second seat for someone else, an admin console and the data default. OpenAI doesn't publish how Pro 100's allowance compares to a Premium seat's in absolute terms, so don't pick between them on "more usage". Pick on whether the work involves client data. Whether the higher Pro tiers are worth it is its own question, answered in is ChatGPT Pro worth it.

Two Pro details that matter this month. Pro 200 is open to new subscribers again, but with a lower allowance than before; if you had Pro 200 at any point between September 22 and September 29, 2026, you keep the old allowance until October 29, 2026, and then it drops. And Pro 500 is the only personal plan with Ultrafast mode, which uses included usage at 8 times the Standard rate. Fast answers, faster burn.

When Business stops being enough

Business is self-serve from 2 seats and covers most small and mid-sized teams. The jump to Enterprise is about controls, not price per seat: SCIM provisioning, enterprise key management, audit logs through the Compliance API, data residency, role-based access control and priority processing. OpenAI doesn't publish an Enterprise price; it's seat fees plus credit-based or token-based usage, negotiated with sales. What it costs in practice and what forces the move is in ChatGPT Enterprise pricing.

Which plan to buy

• Free to find out whether ChatGPT fits your work at all.
• Go ($8) for light personal use, if ads don't bother you.
• Plus ($20) for one person, personal work, no client data.
• Pro ($100 to $500) for one heavy user who keeps hitting the 5-hour wall and doesn't need a business workspace.
• Business ($20 to $25 a seat, 2 minimum) the moment two or more people use it for the business, or any client or employee data goes in.
• Enterprise when security or procurement asks for SCIM, audit logs or data residency.

Buying the seats is the easy part. Getting a team to use them the same way (shared projects, connected apps, who can share what) is where the money is made or wasted. That's the ChatGPT Business setup I do for small teams. The seats are paid to OpenAI; my setup is separate.
