LLM API Cost Calculator Prices 26 Models

The strongest value is forcing workload assumptions into an actual bill before deployment. The benchmark also gives the calculator credibility by challenging simplistic claims that caching automatically halves normal chatbot spend.

• –Editable pricing keeps the spreadsheet useful as providers change rates.
• –The comparison tab ranks the same workload across 26 models, making model-switching tradeoffs concrete.
• –Cache savings are modeled explicitly instead of treated as guaranteed; exact repeats were only 1.49% across 172,418 real chat turns.
• –Usage logs and budget projections extend it beyond a one-off estimate into lightweight spend monitoring.
• –A one-time $7 purchase with no subscription is accessible, though teams needing live billing telemetry will outgrow a spreadsheet.
