Our Mission
AI Cost Calculator is a free, independent tool built for developers, teams, and organizations building on LLM APIs. We believe cost transparency should be universal, not a premium feature.
Every day, teams ship AI applications that could cost thousands of dollars in API fees. Yet most developers discover the real cost only after receiving their first bill. We're here to fix that.
How It Works
100% Local
All calculations run entirely in your browser. No data is sent to servers. Your API keys, prompts stay on your device.
Real-time Comparison
Enter token counts and instantly see cost differences across models. Sort by price to find the best fit for your workload.
Dual Currency
Switch between USD and CNY with one click. Exchange rates are updated regularly from reliable sources.
Visual Breakdown
Colored bars show cost components. Hover tooltips explain cache impact, output costs, and price-per-token metrics.
How Prices Are Sourced
Model prices are maintained manually from official provider pricing documentation. Each model entry includes:
- Source link to the official pricing page
- Last-updated date for verification
- Separate rates for cache hit, cache miss, and output tokens
Important: Prices are planning estimates. Always verify with official billing dashboards before making budget decisions. Provider pricing can change without notice.
