    Claude API cost vs subscription: Claude Code plan break-even

    Published · Last updated · Prices last checked

    A Claude plan is a flat fee: Pro $20, Max $100, Ultra $200 a month. The API bills per token. When your Claude Code usage would cost more than the fee at API rates and fits the plan's limits, the plan is cheaper.

    "Plan saves" means your usage would cost more at API rates than the plan fee. It does not mean the plan's limits are big enough for that usage, since Anthropic does not publish plan limits in tokens. Below break-even, pay per token is cheaper. Prices checked 2026-11-11.

    How it works

    1. One session's API cost is each token count times its price per million tokens, from Anthropic's model pricing table:
      session = (input × input price
        + cache writes × 5-minute cache write price
        + cache reads × cache hit price
        + output × output price) ÷ 1,000,000
    2. Monthly API cost = session cost × sessions per day × working days per month. If you enter the dollar figure from /usage, that replaces the session cost.
    3. For each plan: break-even sessions per month = plan fee ÷ session cost. Above that number the plan costs less than the API. Below it, the API costs less.

    Check of the formula: Anthropic's sample session (1.2k input, 5.3k output, 940k cache read, 50k cache write on Claude Sonnet 4.6) shows $0.55 on the costs page. Sonnet 4.6 list prices give 1,200 × $3 + 50,000 × $3.75 + 940,000 × $0.30 + 5,300 × $15, divided by a million, which is $0.55.

    Assumptions and limits

    • Plan limits are not published in tokens. The pricing page describes them as multiples ("5x Pro usage") that depend on model, chat length and file size. The calculator compares money only. It cannot tell you whether your usage fits under a plan's limit; /usage on a plan shows how close you are.
    • Cache writes use the 5-minute rate. Claude Code sessions can also write to the 1-hour cache, which costs more.
    • Standard API rates only. Fast mode, batch, US-only inference (1.1x) and Haiku 5.5 prompts over 100,000 tokens change the price; see the pricing page.
    • Max and Ultra include $100 and $200 a month in API credits for the Claude Platform. The calculator does not subtract them from the fee.
    • Plan fees exclude tax. Team prices are per seat; Enterprise ($20 per seat plus usage at API rates) is left out.
    • The form starts with example values. They are not averages and not a recommendation.

    FAQ

    Is the Claude API cheaper than a subscription?

    Only for light use. The API bills every token, so cost grows with use. A plan is a flat fee with usage limits. Once your monthly API bill would pass the plan fee (the break-even in the calculator), the plan is cheaper, as long as your work fits inside its limits.

    How much does Claude Code cost per month?

    On a plan, the fee: Pro is $20 a month billed monthly or $17 a month billed annually, Max is $100, Ultra is $200 (claude.com/pricing, checked 2026-11-11). On the API you pay per token. Anthropic's Claude Code costs page says enterprise deployments average about $13 per developer per active day and $150 to $250 per developer per month, with 90% of users under $30 per active day.

    Is Claude Code included in Pro and Max?

    Yes. The pricing page says Claude Code is included in all paid plans and shares the same usage limits as the rest of the plan, so chats and terminal work draw from one pool (claude.com/pricing).

    What happens when I hit my plan's limit?

    You can wait for the limit to reset, move to a higher plan, or turn on usage credits, which keep you working at standard API rates (claude.com/pricing). Usage past the limit is then billed like the API, so the calculator's API figure is the price of that extra work.

    Does the plan cover Claude Fable 5.2?

    On Pro, Fable is paid with usage credits. On Max and Ultra it is included for up to half the weekly limit. On Team, the pricing page lists it for Premium seats, up to half the weekly limit (claude.com/pricing, checked 2026-11-11). Pick Fable 5.2 in the calculator to see these notes next to each plan.

    Where do I find my real token numbers?

    Run /usage in Claude Code. Its Session block lists input, output, cache read and cache write tokens and a dollar figure at list price (Track your costs). The totals reset when /clear starts a new session.

    Is anything I type sent to a server?

    No. The math runs in JavaScript in your browser. There is no backend, no API key and no tracking of what you enter.
