LLM Token Count & Cost Calculator
Estimate token counts from word count and calculate costs for different LLM models.
Calculate costs for processing large batches of documents through an LLM.
Formula
Estimated Tokens = Word Count x 1.33. Cost = (Tokens / 1,000,000) x Rate per Million Tokens. Total Cost = Cost per Call x Number of Calls.
Frequently Asked Questions
How many tokens are in a word?
On average, one English word is approximately 1.33 tokens. This ratio varies by language and content type. Technical text or code may have different ratios. Most tokenizers split words into subword pieces.
Why do input and output tokens have different prices?
Output tokens cost more because generating text requires more computational resources than processing input. The model must perform sequential inference for each output token, while input tokens can be processed in parallel.
