Costs are estimates from token counts and published API rates. Lever assumptions: cache reads billed at ~10% of the input rate (cache writes excluded; exact discounts vary by provider), reasoning tokens billed at the output rate, batch discount 50% where offered. Exchange rates are approximate.

How to Estimate Monthly LLM API Costs

  1. 1

    Set your usage parameters

    Enter your average prompt size, response length, and daily call volume. Pick a preset like Chatbot or RAG to auto-fill typical values.

  2. 2

    Review monthly estimates

    The calculator shows estimated monthly costs for every model, sorted from cheapest to most expensive.

  3. 3

    Filter and compare

    Narrow results by provider, switch currencies, and find the model that fits your budget and performance needs.

Why Use This Cost Calculator

  • Built-in presets for Chatbot, RAG, Code Generation, and Summarizer workloads
  • 162+ models compared side by side with real pricing data from each provider
  • Multi-currency support, see costs in USD, EUR, GBP, INR, or JPY
  • Adjustable prompt size, response size, and daily call volume with instant recalculation

Common Use Cases

Startup budgeting

Estimate monthly API costs before you build. Compare providers to find the best price-to-performance ratio for your use case.

Scaling projections

Model how costs grow as your daily call volume increases. Identify where you'd hit budget limits.

Provider comparison

Compare the total monthly cost of running the same workload on GPT-5 vs Claude vs Gemini.

Use case optimization

See how switching from long prompts to shorter ones, or vice versa, affects your bill across models.
