Claude Haiku 5.5 Pricing Calculator is an independent, free browser tool for estimating Claude Platform API cost. Enter input tokens, output tokens, cached input, cache-write tokens, and requests per month. It applies the published two-tier rates: prompts up to 100,000 tokens are $0.10 per million input and $0.50 per million output; prompts over 100,000 tokens are $0.50 and $2.50. Cache-read and five-minute cache-write rates are included, with optional Batch API (50% off) and US-only inference (1.1x). The page also compares the same workload with Haiku 4.5. Every calculation stays in the browser. No account, no signup, and no prompt data is collected. The calculator is free to use.
Published Haiku 5.5 prices change with prompt length, prompt caching, Batch API, and US-only inference. This calculator was built so a developer can turn those published per-million rates into a per-request and monthly estimate, and compare them with Haiku 4.5, without leaving the browser or creating an account.
