Stress-test scale by changing traffic and output length without changing your main result.
Calculate your baseline first
It multiplies requests per day by input and output tokens per request, applies your price per 1M tokens, then adjusts for cached-input pricing and batch discounts. Everything runs locally in your browser.
Many AI APIs bill prompt/input tokens and generated/output tokens at different rates. Output tokens are often more expensive, so long responses can dominate the final monthly cost.
No. The calculator uses client-side JavaScript only. It does not fetch external APIs, send usage values, store data in localStorage, or require an API key.
Results are estimates generated locally from the usage and pricing values you enter. Provider prices, discounts, taxes, minimum charges, retries, tool calls, images, embeddings, storage and rounding can change the final invoice. Always verify against your provider’s current pricing page and billing export before making production or procurement decisions. VisionVix accepts no liability for decisions based on this output.
