Estimate · anthropic-bpe-estimate · ≈3.5 chars/token Auto-counts as you type

This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Frequently asked.

Practical pricing questions, with vendor list prices separated from workload assumptions.

Q · 01 What is Claude Opus 4.1 priced at? +
Anthropic's pricing page lists $15/M input, $75/M output, and $1.5/M cache-hit input for Claude Opus 4.1. Under the 92/8 agentic blend with 82% cache hits, that works out to $9.616/M.
Q · 02 How does prompt caching change the price? +
Cache hits are listed at $1.5/M, which is 10% of the $15/M base input rate. Anthropic also charges cache writes at $18.75/M for 5-minute writes and $30/M for 1-hour writes. The calculator models repeated prompt sections as cache hits.
Q · 03 Is there a Batch API discount? +
Yes. Anthropic's Batch API gives a 50% discount on input and output tokens. For Claude Opus 4.1, the batch table maps to $7.5/M input and $37.5/M output.
Q · 04 Does long context cost extra? +
This page uses the model's documented 200K context label. Longer-context Opus 4.6, Opus 4.7, and Sonnet 4.6 use standard pricing across the full 1M window. Prompt caching and batch discounts still apply according to their normal rules.
Q · 05 Does regional pricing differ? +
Anthropic says earlier models do not support the inference_geo parameter and use standard first-party API pricing. Bedrock and Vertex AI publish their own regional pricing policies.
Q · 06 Are volume discounts published? +
No fixed public volume-discount ladder is published. Enterprise and committed-spend contracts can have private terms, but standard API users should assume the list prices shown here unless they have a separate agreement.
Q · 07 How accurate is the tokenizer estimate? +
The live counter uses a Claude-family English estimate of 4.875 characters per token. Actual billing uses Anthropic's server-side tokenizer; code, tables, and non-English text can differ materially.
