AI Model Cost Calculator

AI model costs depend on how many tokens you process, and the split between input and output. Input tokens (your prompts) and output tokens (model responses) are priced separately, with output tokens typically costing 2-5x more.

Use this calculator to estimate monthly costs based on your expected usage. Adjust the number of daily requests, average tokens per request, and the input/output ratio. Select up to 5 models to compare their costs side by side.

Pricing data is sourced from OpenRouter and updated daily. Actual costs may vary based on caching, batch discounts, and provider-specific pricing tiers. For the most accurate estimate, start with your real usage numbers from your API dashboard.
