ChatGPT Pricing Calculator 2026: Every Plan, Team Seats, and API Cost
Built by R.K., Creator and Business Economics Analyst · Updated September 20, 2026How much does ChatGPT cost in 2026? This ChatGPT pricing calculator covers all six subscription tiers plus API rates in one place. ChatGPT runs six tiers: Free ($0, GPT-5.6 Luna, limited), Go ($8/month, roomier limits, not the flagship model), Plus ($20/month, GPT-6 Astra plus the full GPT-5.6 family, image generation, Codex, and Deep Research), Pro ($100/month for 5x usage or $200/month for 20x usage, with Pro reasoning powered by Astra), Business (Standard seats at $20-25/seat/month or Premium seats at $100-125/seat/month, 2-seat minimum), and Enterprise (custom pricing). The API is billed separately, per token, starting at $0.20/$1.20 per million tokens on GPT-5.6 Luna up to $10.00/$50.00 on GPT-6 Astra. Use the calculator below for your exact number.
ChatGPT’s pricing page looks simple until you actually have to decide what to buy. Six subscription tiers, two separate Pro price points, a Business plan that now has two different seat tiers, and a completely separate per-token API billing system that shares no relationship with any of the subscription prices above it.
This ChatGPT pricing calculator covers all three buying situations in one place, plus a fourth: projecting cost forward as a team grows. Pick the tab that matches your situation below.
ChatGPT pricing has changed multiple times in 2026 already, most recently with the GPT-6 Astra launch on September 3. Every price in the calculator below is editable under “Advanced” – if OpenAI updates a rate before we do, check the official pricing page linked there and enter the new number yourself. Your result updates instantly using your figure, not a hardcoded one.
How to Use This ChatGPT Pricing Calculator

Most calculators show one month. If you are budgeting for a growing team, that undersells the real number. This tab projects Business seat cost forward 12 months as headcount changes.
Full ChatGPT Plan Comparison, Free Through Enterprise
| Plan | Price | Model | Best For |
|---|---|---|---|
| Free | $0 | GPT-5.6 Luna, limited | Occasional, light use |
| Go | $8/mo | Not flagship, roomier limits | Frequent basic chat, budget-conscious |
| Plus | $20/mo | GPT-6 Astra plus GPT-5.6 family | Most individual professionals |
| Pro (5x) | $100/mo | Pro reasoning via GPT-6 Astra | Heavy daily users exceeding Plus limits |
| Pro (20x) | $200/mo | Pro reasoning via GPT-6 Astra | Power users exceeding the $100 tier |
| Business Standard | $20-25/seat/mo | GPT-6 Astra plus GPT-5.6 family | Teams of 2+, needs admin, SSO, compliance |
| Business PremiumNew 2026 | $100-125/seat/mo | Same models, 5x usage | Teams that would otherwise outgrow Standard limits |
| Enterprise | Custom | GPT-6 Astra plus GPT-5.6 family | Large orgs needing SCIM, data residency, custom SLA |
API access is not included in any plan above and is billed separately, per token. See the API Cost tab in the calculator.
What Is ChatGPT Go?
ChatGPT Go is OpenAI’s cheapest paid tier, priced at $8 per month, which launched globally on January 16, 2026 and is available in 98 countries. It sits between Free and Plus: you get meaningfully roomier usage limits than the Free plan, but you do not get GPT-6 Astra or the flagship GPT-5.6 Sol model that Plus subscribers use, and the plan may include ads. Go is the right call if you consistently hit Free’s limits but do not need image generation, Codex, the Work agent, or Deep Research – for any of those, Plus at $20/month is the tier to compare against instead.
ChatGPT vs Claude: Which Costs Less?
At the individual subscription level, ChatGPT Plus and Claude Pro are both $20/month, and both offer $100/$200 power tiers, so subscription price alone will not decide it. The real cost gap shows up at the API level, where per-token pricing varies significantly by model and provider, and where OpenAI’s newest flagship, GPT-6 Astra, now sits well above Anthropic’s comparable tiers on a per-token basis. See our full AI Model Pricing Comparison for the exact OpenAI, Anthropic, and Google breakdown at your token volume.
Methodology: How Each Number Above Is Calculated
Every figure this calculator produces comes from one of four plain formulas, shown below with a worked example for each. Nothing is estimated by a model or guessed – it is arithmetic on the rates you see, or override, in each tab.
Individual Plan recommendation
This is rule-based, not a formula: your answers to usage frequency, flagship-model need, limit-hitting, and budget sensitivity are checked against a fixed decision order (Free first, then Go, then Pro, then Plus as the default fit), and the first matching rule wins. The displayed price is simply the current value of that plan’s price field, whether default or overridden.
Team and Business seat cost
annual_total = monthly_total x 12
# comparison shown against individual Plus subscriptions
plus_total = seats x plus_price
difference = monthly_total – plus_total
Worked example: 10-person team, Standard seats, annual billing
- monthly_total = 10 x $20.00 = $200.00/month
- annual_total = $200.00 x 12 = $2,400/year
- plus_total = 10 x $20.00 = $200.00, so difference = $0.00 at current pricing
- the same team on Premium seats would run 10 x $100.00 = $1,000.00/month instead
API token cost
+ (output_tokens / 1,000,000 x output_price)
monthly_cost = cost_per_call x monthly_calls
Worked example: GPT-6 Astra, 1,000 in / 500 out tokens, 10,000 calls/month
- input cost = (1,000 / 1,000,000 x $10.00) x 10,000 = $100.00
- output cost = (500 / 1,000,000 x $50.00) x 10,000 = $250.00
- monthly total = $100.00 + $250.00 = $350.00/month
Output pricing runs a consistent 6x input on every GPT-5.6 tier, and 5x on GPT-6 Astra, reflecting that generating output requires repeated inference per token while reading a prompt is a single pass. Check each model’s own ratio rather than assuming a universal multiple.
12-month growth simulation
seats(month) = seats(month – 1) + net_seats_per_month
cost(month) = seats(month) x price_per_seat
total_12mo = sum of cost(month) for month 1 through 12
Worked example: starting at 5 seats, adding 2/month, Standard annual
- month 1: 5 seats x $20.00 = $100.00
- month 12: 5 + (2 x 11) = 27 seats x $20.00 = $540.00
- summed across all 12 months = roughly $4,160 total, well above simply multiplying month-1 cost by 12
How This Calculator Is Built
Subscription prices are checked directly against chatgpt.com/pricing, and API token rates against OpenAI’s official API pricing documentation, as of September 20, 2026. OpenAI has changed ChatGPT pricing and model access multiple times within 2026, including the Business plan’s April price cut, the Go tier’s January launch, and the GPT-6 Astra release on September 3 that reshuffled which model counts as “flagship.” Rather than relying only on periodic manual re-checks, every price in this calculator is directly editable under each tab’s “Advanced” section – if a rate changes before we update it, you can enter the current number yourself and get an accurate result immediately. The Individual Plan recommendation logic and the 12-month simulator are planning aids based on typical usage and growth patterns, not a guarantee that a given tier or growth path fits your exact situation.

Frequently Asked Questions
Is ChatGPT Plus worth it in 2026?
For most individual professionals, yes. Plus costs $20/month and unlocks GPT-6 Astra and the GPT-5.6 model family, image generation, Codex, the ChatGPT Work agent, Deep Research, and custom GPTs, all of which the Free plan either lacks or heavily limits. The Free plan runs on GPT-5.6 Luna with tight usage caps. If you use ChatGPT daily for real work rather than occasional questions, Plus pays for itself; if you use it a few times a week, Free or the $8 Go tier is usually enough.
What is GPT-6 Astra and which ChatGPT plans include it?
GPT-6 Astra is OpenAI’s current frontier model, released September 3, 2026, priced at $10 input and $50 output per million tokens through the API, about 2.5 times GPT-5.6 Sol’s rate. ChatGPT Plus includes standard access to Astra alongside the GPT-5.6 family, while Pro adds a higher-usage Pro reasoning mode powered by Astra. Free and Go do not include Astra.
What is ChatGPT Go and how is it different from Plus?
ChatGPT Go is OpenAI’s budget tier at $8/month, available in 98 countries since it launched globally on January 16, 2026. It gives roomier usage limits than the Free plan but does not include GPT-6 Astra or the flagship GPT-5.6 Sol model, and may show ads. Go fits users who exceed Free’s limits but do not need image generation, Codex, or Deep Research. Plus, at $20/month, is the tier most professionals should compare it against, not Free.
How many ChatGPT Business seats do I need, and what does it cost per seat?
ChatGPT Business requires a minimum of 2 seats and now comes in two seat tiers: Standard at $20 per seat per month on annual billing or $25 monthly, and a Premium seat at $100 per seat annually or $125 monthly with 5 times the usage allowance. At 2 or more seats, Standard often costs the same per person as individual Plus subscriptions while adding shared workspaces, SAML SSO, admin controls, SOC 2 Type 2 and ISO 27001, 27017, 27018, and 27701 compliance, and a guarantee that your data is not used for model training. For teams under 2 people, individual Plus subscriptions remain the only option.
Does a ChatGPT Plus or Business subscription include API access?
No. ChatGPT subscriptions (Free, Go, Plus, Pro, Business, Enterprise) and the OpenAI API are billed completely separately. A Plus subscription includes zero API credits. If you need to call GPT models programmatically, you pay per token through the API regardless of which ChatGPT subscription plan you or your team are on.
What is the difference between the $100 and $200 ChatGPT Pro tiers?
Both give you Pro reasoning powered by GPT-6 Astra and remove the usage caps that limit Plus. The difference is usage headroom: the $100/month tier gives roughly 5 times Plus-level usage, while the $200/month tier gives roughly 20 times Plus-level usage, plus the largest context window and around 250 Deep Research tasks a month. OpenAI’s own help center describes both tiers as sharing the same core capabilities; the higher tier exists for users who exhaust the lower tier’s limits.
How much does the ChatGPT API cost per message?
It depends entirely on the model and message length, since API pricing is per token, not per message. On GPT-5.6 Sol, currently $4 input and $20 output per million tokens under promotional pricing through November 21, 2026, a typical 1,500-token exchange costs a fraction of a cent to a few cents depending on output length. GPT-6 Astra, the newer flagship, runs $10 input and $50 output per million tokens. Use the API Cost tab in the calculator above with your actual token counts for an exact figure.
Is there a ChatGPT Premium plan?
No, OpenAI has never had a plan officially named “ChatGPT Premium.” When people search for this, they almost always mean ChatGPT Plus at $20/month, the tier that unlocks GPT-6 Astra and GPT-5.6 Sol. If you’re thinking of the top of the lineup instead, that’s ChatGPT Pro at $100 or $200/month. If a site or ad quotes a “ChatGPT Premium price,” read it as Plus pricing unless Pro is explicitly named.
Is ChatGPT cheaper than Claude?
At the individual subscription tier, both ChatGPT Plus and Claude Pro cost $20/month, and both sell $100/$200 power tiers, so subscription price alone will not decide it. The differences that matter are in what each tier unlocks. See our full AI Model Pricing Comparison for the API-level cost breakdown across OpenAI, Anthropic, and Google.
