How the limits work
Five-hour windows on Plus and Business
OpenAI gives Codex estimates as local messages per five-hour window for Plus and Standard Business, by model. They are estimates, not fixed limits, and weekly limits may also apply.
Pro tiers
Pro is sold at three prices, billed monthly only. OpenAI says each tier gets more usage than the one below but publishes no multiple of Plus, and the Pro plans currently have no five-hour limit.
Credits after the allowance
Plus and Pro subscribers can buy credits to keep working after the included usage. Included usage is spent first, then the credit balance. The pages we read do not state the dollar price per credit.
The Codex mechanics, with their sources, live on the Codex usage-limits page. This page does not show any account's remaining allowance.
Plan versus API: what the same money buys
OpenAI does not publish the plan allowances in tokens or dollars, so no exact break-even exists. What can be computed is what each plan price buys at GPT-6.1 Sol list rates ($2 input and $10 output per million tokens, pricing registry updated October 29, 2026). The figures are arithmetic on published rates, not a statement of the plan's allowance.
| Plan price | Million input tokens | Million output tokens |
|---|---|---|
| Plus, $20 a month | 10M | 2M |
| Pro 100, $100 a month | 50M | 10M |
| Pro 200, $200 a month | 100M | 20M |
| Pro 500, $500 a month | 250M | 50M |
A workload that needs fewer tokens than that is cheaper on the API, because the plan price is a floor. Use the calculator below to put your own workload beside a plan price.
Plan price beside the API list cost of a workload
Pick a plan, a GPT model and a workload. The API side is list rates times the tokens you enter, the same arithmetic as the pricing calculator. The plan side is its published price; its cap is not published.
- Go price
- $8.00/month
- Included usage: More messages with tools, more uploads, more image creation, more voice chats and longer memory than Free; limited Codex access, allowance not itemized on the page.
- Same tokens on the API, list rates
- $12.00/month
- 2,000,000 input and 800,000 output tokens a month on GPT-6.1 Sol.
- Does the plan cover it?
- Unavailable
- The plan does not publish its included usage in credits or dollars; no equivalent can be computed. At this workload the API bill is above the plan price; past the plan's cap, extra usage is billed at the same API rates.
Estimate only, at list rates from the pricing registry. It excludes reasoning tokens billed as output, batch discounts, taxes and provider minimums. Confirm the exact model identifier in the model ID directory and the rate on the OpenAI API pricing hub.

Questions
How much does ChatGPT cost?
ChatGPT Free costs $0, Go is $8 a month, Plus is $20 a month, Pro comes in three tiers at $100, $200 and $500 a month, and Business is $25 per user a month ($20 billed annually, 2 or more users). Enterprise and Edu have no published price. Read 2026-10-16.
Is ChatGPT free?
Yes. The Free plan costs nothing; chatgpt.com/pricing lists unlimited text chats with GPT-6 (subject to abuse guardrails), limited uploads, image creation, voice chats, deep research and Codex access. The Codex pricing page lists GPT-6 Luna at Standard speed in the desktop app, subject to rollout.
What is the difference between ChatGPT Plus and Pro?
Plus is $20 a month with Codex estimates published per five-hour window. Pro comes in three tiers at $100, $200 and $500 a month, billed monthly only, with expanded model access, Pro reasoning and no five-hour limit for now. OpenAI publishes no multiple of Plus for the Pro tiers; only Pro $500 includes Ultrafast mode.
Which models come with ChatGPT Plus?
GPT-6 Astra, GPT-6.1 Sol, GPT-6 Sol and GPT-6 Luna in Codex; GPT-6.1 Sol is available in Work and Codex, not Chat. Estimated local Codex messages per five-hour window: 5 to 45 with GPT-6 Astra, 15 to 160 with GPT-6.1 Sol, 15 to 150 with GPT-6 Sol, 350 to 3,000 with GPT-6 Luna; weekly limits may also apply.
What happens when I hit the ChatGPT usage limit?
Plus users who reach the limit can purchase additional credits without upgrading. On Pro, included usage is used first and then the credit balance. OpenAI's pages do not state the dollar price per credit. Our Codex usage-limits page keeps the mechanics with their sources.
Is ChatGPT Plus cheaper than the API?
OpenAI does not publish the Plus allowance in tokens or dollars, so no exact break-even exists. What can be computed is what the plan price buys at list rates: $20 is 10 million input tokens or 2 million output tokens of GPT-6.1 Sol at $2 and $10 per million. If your workload needs less than that, the API is cheaper.
