About the AI Token & API Cost Calculator
Plan your AI budget before you build. Enter your traffic and prompt sizes, choose or type a price per million tokens, and see daily, monthly and yearly cost in USD and INR.
How it works
Cost = requests × (input tokens × input price + output tokens × output price) ÷ 1,000,000. Cached input tokens are billed at the cache-read price you enter. Presets are examples only — always check the provider’s current pricing page.
Frequently asked questions
How many tokens is a word?
In English, one token is roughly ¾ of a word, so 1,000 words ≈ 1,330 tokens.
Are the preset prices current?
They are editable examples. AI pricing changes often, so type in the latest price from your provider.
