Methodology

Methodology

PromptMeter estimates tokens from text length and approximate chars-per-token profiles. It does not use official tokenizers.

Cost per prompt run is estimated from input tokens, expected output tokens, workflow calls, and manual or example prices per 1M tokens.

Monthly cost multiplies the estimated cost per run by the selected daily volume and days per month.

Prompt savings are mathematical scenarios based on reducing input tokens by 10%, 25%, or 50%. PromptMeter does not rewrite prompts yet.

The AI API Cost Calculator estimates users, requests, AI calls, input/output tokens, daily cost, monthly cost, yearly cost, and scale scenarios.

All calculations are approximate. Verify official pricing, usage dashboards, model behavior, and tokenizer counts with your AI provider.

PromptMeter is static, has no backend for prompt processing, and does not send prompts to a PromptMeter server.
