About This Calculator

Costs are calculated using the industry-standard token pricing formula:

Total = (Input Tokens × Input Cost + Output Tokens × Output Cost − Cached Tokens × Cache Savings) ÷ 1,000,000

All prices are in USD per million tokens. Cached token savings apply when your provider supports prompt caching, reducing repeat input costs. These figures are estimates based on publicly available pricing as of August 2026.
