What is LLM Cost Calculator?
The LLM Cost Calculator helps developers and teams estimate what they will spend on AI API calls. Whether you are building an AI-powered product, running inference at scale, or just curious about pricing differences across providers, this tool gives you a transparent, sortable comparison.
Enter your estimated monthly input tokens, output tokens, and requests per month. The tool calculates total monthly cost for each model based on current 2026 pricing. Sort by any column — model name, provider, price, or total cost. Filter by provider to narrow the comparison. The cheapest model is automatically highlighted, and the savings panel shows how much you would save compared to the most expensive option. Export results as CSV for your project proposals or budget planning.
Pricing data reflects publicly listed API prices as of mid-2026. Actual costs may vary by provider region, commitment level, or usage tier. Always verify with official pricing pages.
FAQ
- How accurate is the pricing data?
- Pricing is based on publicly listed API rates as of mid-2026. Providers occasionally update their pricing, so always verify on the provider official pricing page before making financial decisions.
- Does this account for batch pricing or reserved capacity discounts?
- No. This calculator uses standard on-demand API pricing only. Providers like OpenAI and Anthropic offer batch processing discounts (usually 50% off) and reserved capacity contracts that can lower costs significantly.
- How are tokens estimated?
- The calculator uses the exact token volumes you enter. It does not estimate tokens from text — only cost calculation. Input and output tokens are priced at their respective per-1M rates.
- Why do some models have equal input and output prices?
- Some providers (like Groq for Llama models) charge a flat rate per 1M tokens regardless of whether they are input or output tokens.
