Frequently Asked Questions

It multiplies monthly requests by average input and output tokens, then applies each model’s input and output price per 1M tokens. Cached input tokens can receive a separate discount to estimate lower reuse costs.

Many LLM vendors price generated output tokens higher than prompt/input tokens. A model that looks cheap for short answers can become expensive when outputs are long, verbose, or generated at high volume.

No. All calculations run locally in your browser. No prompts, API keys, request counts, or pricing inputs are sent anywhere. Update the pricing fields manually if your provider changes rates.

Calculation Disclaimer

Results are estimates generated locally from the pricing and usage values you enter. They exclude taxes, minimum fees, batch discounts, fine-tuning, embeddings, storage, moderation, retries and provider-specific billing rules unless you manually include them in the rates.
