How This Calculator Works
Enter your expected usage — tokens per request, requests per day, and days per month — and the calculator shows your estimated cost per request, cost per 1K requests, and monthly total for any of 33 LLM models across 10 providers. Use the "Typical request" presets to quickly see what common workloads cost. It also suggests the cheapest alternative if a cheaper model can handle your workload.

Use the Comparison ToolTips to Reduce Your API Costs
The calculator often reveals that a cheaper model can handle your workload. Here are the biggest cost-saving strategies:
- Use budget models for simple tasks: GPT-4o mini ($0.15/$0.60) handles 80% of chatbot requests at 1/17th the cost of GPT-4o
- Optimize prompts: Shorter prompts = fewer input tokens = lower costs
- Set token limits: Don't let models generate 4000 tokens when 200 will do
- Cache responses: Identical prompts can be cached to eliminate redundant API calls
