Cost Calculation

Formula: (Input Tokens × Input Price) + (Output Tokens × Output Price)

Prices shown are per 1,000 tokens (1K). For 100 tokens, divide by 10. For 1M tokens, multiply by 1,000.

How to Use This Tool

1. Select your model – Choose from GPT-4, GPT-3.5, Claude, or other LLM providers
2. Enter token counts – Input estimated input and output tokens for your request
3. View instant cost – See total cost breakdown and cost per request
4. Copy result – Use "Copy Total Cost" to save the calculation

Why Calculate API Costs?

• Budget planning for LLM-powered applications
• Understand pricing differences between models
• Optimize prompt length to reduce costs
• Estimate costs before scaling production workloads
• Compare cost-efficiency across LLM providers

Example

Scenario: Processing 1,000 requests with 500 input tokens and 200 output tokens each

• GPT-4 Turbo: (500 × $0.01 + 200 × $0.03) × 1,000 = $7,000/month
• GPT-4o: (500 × $0.005 + 200 × $0.015) × 1,000 = $3,500/month
• Claude 3 Opus: (500 × $0.015 + 200 × $0.075) × 1,000 = $22,500/month
