Cost My Tokens is a free LLM API cost calculator for developers. Enter token counts or paste text into the Token Counter, then compare what you would pay on official APIs versus popular gateways. We track models from OpenAI, Anthropic, Google, DeepSeek, xAI, Kimi and others, with prices verified against official docs and dated on each page. Rankings sort by price only; affiliate links are disclosed and never change the order.
