AI Model Cost Comparison Calculator
Compare estimated GPT, Claude, and Gemini API costs using the same input tokens, output tokens, request count, and editable model prices.
What does this calculator answer?
AI model cost comparison applies the same token workload to different input and output prices. This helps separate usage volume from provider pricing before deeper quality testing.

Before you enter values
- Enter input tokens per request in tokens so the estimate uses the same unit throughout.
- Enter output tokens per request in tokens so the estimate uses the same unit throughout.
- Enter requests in calls so the estimate uses the same unit throughout.
- Enter gpt input price in $/1M so the estimate uses the same unit throughout.
- Enter gpt output price in $/1M so the estimate uses the same unit throughout.
- Enter claude input price in $/1M so the estimate uses the same unit throughout.
- Enter claude output price in $/1M so the estimate uses the same unit throughout.
- Enter gemini input price in $/1M so the estimate uses the same unit throughout.
- Enter gemini output price in $/1M so the estimate uses the same unit throughout.
How to read the result
- Start with 'GPT estimated cost'. This is the main output for the current assumptions.
- Then compare 'Claude estimated cost' so you do not judge the scenario from one number alone.
- Then compare 'Gemini estimated cost' so you do not judge the scenario from one number alone.
Formula
Model cost = input tokens × calls ÷ 1,000,000 × input price + output tokens × calls ÷ 1,000,000 × output price
Example
Using 2,000 input tokens, 700 output tokens, and 5,000 calls, each provider total changes directly with its editable per-million token prices.
Common mistakes
- Choosing only by price without quality tests
- Ignoring caching, batching, or rate limits
- Forgetting non-text charges such as search, images, audio, or tool execution
