AI Token Cost Calculator
Estimate API pricing for popular LLM models like GPT-4o, Claude 3.5 Sonnet, and DeepSeek, with support for batch calls and agent loops.
Preguntas Frecuentes
How are LLM API costs calculated?
API costs are calculated based on the number of prompt (input) tokens and completion (output) tokens, multiplied by the model's rate per million tokens.
What is a token?
A token is a basic unit of text, representing about 4 characters or 0.75 words. For example, 100 tokens is approximately 75 words.
Why do AI agents consume more tokens?
AI agents operate in loops, appending previous turn history to the prompt of the next turn. This context expansion means input tokens scale quadratically, increasing costs per run.
How does the budget longevity estimate work?
The calculator takes your monthly budget and divides it by the cost of your simulated usage, giving you the total runs and days your budget will last.
How to Use the AI API Pricing Calculator
Estimate the cost of using large language model APIs based on token usage.
- Select a model or enter per-token prices.
- Enter expected input and output tokens.
- Enter your request volume.
- See the cost per request and monthly total.
Token Cost
Request Cost
API prices are usually quoted per million tokens.
Example:
Input: 1k in + 500 out at $3/$15 per M
Calculation: (1000×3 + 500×15)/1e6
Result: ≈ $0.0105/request

Tips
- Output tokens often cost more than input tokens.
- Caching and shorter prompts cut costs significantly.
