AI Model Pricing Calculator
Calculate and compare API costs for ChatGPT, Claude, Gemini, and other AI models
How This Calculator Works
This tool helps you estimate API costs for different AI models based on your projected usage. Enter your monthly token usage or requests, and we’ll calculate the costs for comparison.
Interactive Pricing Calculator
Step 1: Estimate Your Monthly Token Usage
Typical usage examples:
- Light User: 100K tokens/month (occasional use)
- Regular User: 1M tokens/month (daily use)
- Power User: 10M tokens/month (heavy daily use)
- Enterprise: 100M+ tokens/month (production applications)
tokens
Adjust the slider or type in a value. 1 token ≈ 4 characters.
requests
Average tokens per request helps calculate total tokens.
Step 2: Review Your Estimated Costs

Important Notes
- Prices are approximate and based on November 2025 rates
- Actual costs may vary based on your specific usage patterns
- Some providers offer discounts for high-volume usage
- Prices may change – check official provider websites for current rates
- Consider request count limits and rate limiting in your plans

Cost Optimization Strategies
Use Cheaper Models for Simple Tasks
- Use GPT-3.5 or Gemini Flash for basic tasks
- Reserve GPT-4 for complex reasoning
- Try Claude Haiku for speed over cost
- Estimated savings: 50-80%
Batch Processing
- Process multiple requests together
- Reduce overhead per request
- Many providers offer batch discounts
- Estimated savings: 20-40%
Caching & Local Models
- Cache frequent responses
- Use self-hosted models for high volume
- Implement fallback to cheaper alternatives
- Estimated savings: 30-60%
Volume Discounts
- Negotiate with providers at scale
- OpenAI: Volume discounts available
- Anthropic: Custom pricing for enterprise
- Estimated savings: 10-30%
Comparison: Monthly Costs at Different Scales
| Monthly Usage | GPT-4 | Claude Opus | Gemini Pro | Cheapest Option |
|---|---|---|---|---|
| 100K tokens | $2-4 | $1.50 | $1 | Gemini: $1 |
| 1M tokens | $40-60 | $15-20 | $10-15 | Gemini: $12 |
| 10M tokens | $400-600 | $150-200 | $100-150 | Gemini: $120 |
| 100M tokens | $4,000-6,000 | $1,500-2,000 | $1,000-1,500 | Negotiate rates |
Frequently Asked Questions
What is a token?
A token is roughly 4 characters of text. For example, the word “hello” = 1 token, and a typical paragraph = 100-200 tokens. Different models may tokenize slightly differently.
How accurate is this calculator?
This calculator provides estimates based on average token counts and current pricing. Actual costs depend on your specific prompts, response lengths, and any applicable discounts. Use these estimates as a guide, not exact figures.
Should I use API or the web interface?
Use the API for programmatic access and cost tracking. Web interfaces (ChatGPT Plus) offer simpler pricing but less control. APIs are better for high-volume and production use cases.
Can I reduce costs further?
Yes! Use cheaper models for simple tasks, cache responses, batch requests, negotiate volume discounts, or self-host open-source models like Llama 2. Multi-model strategies often yield the best cost-benefit.
