claude api cost calculator
Use the worksheet to turn public rules, dates, and assumptions into a decision-ready estimate.
Use this Claude API cost calculator and token cost estimator to estimate input tokens, output tokens, monthly spend, and per-request cost with editable Claude and Anthropic pricing.
Use the worksheet to turn public rules, dates, and assumptions into a decision-ready estimate.
Designed for people who need a practical calculation before they compare official sources.
This Claude API cost calculator estimates monthly spend from daily requests, average token usage, and editable Claude input and output token prices, so it also works as a practical token cost estimator and Anthropic pricing worksheet.
Adjust the assumptions, then use the result as a planning estimate. Official sources still control eligibility and reporting.
Adjust the inputs, review the assumptions, and verify source links before making a decision.
A Claude price table does not tell you what a real workflow costs. Monthly spend depends on request volume, long system prompts, retrieved documents, tool use, cached prefixes, and how much output the feature generates.
Open the official Anthropic pricing page, choose the exact Claude model, and copy the current input and output prices. Do not treat screenshots or old benchmarks as a production budget source.
Claude estimates usually drift when long context, uploaded documents, tool schemas, or repeated system instructions inflate the input-token count. Budget the production request shape, not the short prompt from a quick prototype.
No. Prices are editable by design. Copy the current Claude model prices from the official Anthropic source before making a budget decision.
Yes, but estimate tokens from the full request shape, including documents, retrieved context, and tool definitions. Long-context Claude workflows can drift far above a short demo prompt.
No. Caching only helps when repeated prompt prefixes meet the provider rules and produce real cache reads. Keep the cached-share fields at 0 until you verify the exact pattern and pricing treatment.
The visible user message may be short while the real request includes system instructions, prior history, retrieved files, tool definitions, or long documents. Token counting should be based on the full API payload.
Yes. If you need a Claude token cost calculator, this page covers that by combining token counts, request volume, and editable Claude prices into per-request and monthly budget estimates.
Yes. Anthropic publishes Claude pricing, so this page can also be used as an Anthropic API cost calculator as long as you copy the current official prices into the editable fields.
Yes, but only after you replace the default prices with the exact model or workflow prices you are using. Long-context prompts and tool-heavy Claude Code patterns can change token totals quickly.
