How This Calculator Works
Use this ai token cost tool for quick estimation, comparison, and planning intent while keeping formula assumptions visible.
Use the AI token cost calculator to estimate API spend before launching prompts, agents, chatbots, or batch jobs.
The calculator multiplies per-request input and output tokens by request volume, then applies per-million-token prices.
Formula
Cost = input tokens / 1,000,000 x input price + output tokens / 1,000,000 x output price.
Example Calculation
10,000 requests with 1,200 input tokens and 500 output tokens at $0.50/$1.50 per million costs about $13.50.
When to Use This Calculator
- Budget an AI feature
- Compare prompt sizes
- Estimate batch processing costs
Practical Scenarios
- Use the AI Token Cost Calculator to budget an ai feature while comparing at least one conservative and one higher-cost scenario.
- Use the AI Token Cost Calculator to compare prompt sizes while comparing at least one conservative and one higher-cost scenario.
- Use the AI Token Cost Calculator to estimate batch processing costs while comparing at least one conservative and one higher-cost scenario.
Tips
- Model prices change, so verify current pricing
- Track output tokens separately
- Add buffers for retries and tool calls
Common Mistakes
- Counting only prompt tokens
- Ignoring failed or retried requests
- Using prototype prompts as if they were final
- Using a best-case input when a realistic range would be safer.
- Forgetting fees, taxes, inflation, usage changes, or other hidden costs where they apply.
Assumptions and Limitations
The AI Token Cost Calculator is most accurate when the inputs match current real-world numbers and when you review the formula, assumptions, and related calculators before acting.
- Provider pricing, runtime overhead, compression, caching, hardware limits, and production traffic can change final requirements.
- The result is a technical planning estimate, not a guarantee of performance or cost.
- Verify against current vendor documentation before committing to infrastructure or hardware.
