Anthropic Pricing
Anthropic charges between $1.25 and $50.00 per 1 million output tokens, depending on the model. Claude 3 Haiku is the cheapest at $1.25/1M output and $0.250/1M input; Claude Fable 5 is the most expensive at $50.00/1M output. The largest context window is 1.0M tokens (Claude 4 Sonnet (2025-05-14)). Prices are USD, current as of July 20, 2026.
Anthropic prices Claude in three tiers — Haiku for high-volume classification and extraction, Sonnet for general production work, and Opus for the hardest reasoning. Output tokens cost roughly 5× input across the lineup, so response length drives your bill far more than prompt size.

Frequently asked questions
How much does Anthropic cost per 1M tokens?
Anthropic pricing ranges from $1.25 to $50.00 per 1 million output tokens across 21 models. Input tokens are cheaper than output on every model. Rates current as of July 20, 2026.
What is the cheapest Anthropic model?
Claude 3 Haiku is the cheapest Anthropic model on both axes — $0.250 per 1M input tokens and $1.25 per 1M output. It is the right default for high-volume, low-complexity work such as classification, extraction and routing.
What is the largest Anthropic context window?
Claude 4 Sonnet (2025-05-14) has the largest context window in the Anthropic catalog at 1.0M input tokens, with up to 64K output tokens per response.
Does Anthropic support prompt caching?
Yes. Claude Sonnet 5 reads cached input at $0.200 per 1M tokens, against $2.00 per 1M uncached. Caching pays off when a long system prompt or document is reused across many requests.
Which Anthropic models support reasoning or vision?
The Anthropic catalog includes 3 reasoning models, 3 vision models, 3 with tool calling. Reasoning models bill their internal thinking as output tokens, so they cost more per visible response than the headline rate suggests.
How do I calculate my actual Anthropic bill?
Multiply your input tokens by the input rate and your output tokens by the output rate, both per million, then add retries and any conversation history resent on each turn. Calcaas does this against your real usage pattern and shows the margin left at your price point.

What will this actually cost you?
Per-token rates only tell you half the story. Calcaas multiplies them by your real usage — prompt size, response length, retries and conversation history — then shows the margin left at your price point.
