Claude Mastery Free ~7 min read Plans, tokens & per-prompt cost

What Claude actually costs.

Claude has a free tier, a $20 Pro plan, two pricier Max tiers, and a per-token API with three model sizes. Here's what each costs and what a real prompt runs you — honest September 2026 numbers.

01 The plans

PlanPriceWho it's for
Free$0Trying Claude, light daily use
Pro$20/moMost users — solid limits, Projects, Artifacts
Max (5×)$100/moHeavy users wanting 5× the usage
Max (20×)$200/moPower users living in Claude all day

In the app, you're not billed per word — you get a usage allowance measured in messages, and the Max tiers simply raise that ceiling. Most people are well served by Pro.

Fable 5 update · July 21, 2026: the launch promotion ended July 19, 2026 (11:59 PM PT) after two extensions, and the plans have split. Since July 20, Max plans and premium Team and Enterprise seats include Fable 5 as standard — up to 50% of weekly limits at no extra cost (it burns limits faster than other models), then usage credits. Pro and standard Team or Enterprise seats don't include it: Fable 5 runs on usage credits — pay-as-you-go at $10 per million input tokens / $50 per million output, enabled under Settings → Usage (prepaid funds, monthly cap, optional auto-reload; $2,000/day redemption limit) — and eligible Pro and Team users get a one-time free credit. The sane playbook is unchanged: everyday work on Sonnet or Haiku, Fable 5 deliberately — and on Pro, with a cap set.

02 Pay-per-use (the API)

Claude's API charges per token (~¾ of a word), and you pick a model size by how hard the job is. Current rates, per million tokens (input / output):

ModelInput / Output (per 1M)Use it for
Claude Haiku$1 / $5Fast, cheap, high-volume tasks
Claude Sonnet 5$2 / $10 — permanent as of Aug 10, 2026The everyday workhorse
Claude Opus 5$5 / $25Near-flagship reasoning & agents (released July 24, 2026)
Claude Fable 5.1$10 / $50The top tier — long, complex, agentic jobs (released Sept 1, 2026)

Fable 5.1 update · September 1, 2026: the per-token rates above did not move, but Fable 5.1 cut its cache read price from $1 to $0.25 per million tokens — 2.5% of the input rate, where every other Claude model charges 10%. Cache reads are what you pay when a request re-uses context the model already processed, so this only helps if you send the same long context repeatedly. Anthropic puts the saving at roughly 25% on typical workloads and up to 45% on heavily agentic ones. Nothing changes if you use Claude in the app — this is an API-side price. Full explainer: Claude Fable 5, explained.

Picking the right size is the whole cost game: Fable is 10× Haiku on input and Opus is 5×. Use the small model for routine work and save Opus for jobs that truly need it.

03 What a prompt actually costs

The honest takeaway

Claude's writing and reasoning quality is its draw — and for normal use, prompts are pennies. The cost lever is model choice: don't run everything on Opus. For most daily work, Pro ($20) flat beats per-token, and Sonnet is the right default if you're on the API.

Quick gut-check

If you're on the API, look at how often you reach for Opus. Most jobs run fine on Sonnet at a fifth the price. Reserving Opus for the genuinely hard ones can cut your bill dramatically without hurting output.

What you can do now

  • Know the plans: Free, Pro ($20), Max ($100 / $200)
  • Read the API rates by model: Haiku $1/$5, Sonnet 5 $2/$10 (now permanent), Opus 5 $5/$25, Fable 5.1 $10/$50
  • If you send the same long context over and over on the API, Fable 5.1’s $0.25 cache-read rate is the cheapest of any Claude model
  • Control cost with model choice — Sonnet by default, Opus sparingly
  • Pick the plan that matches your real usage
