Method, assumptions, and limits
The calculator multiplies input and output tokens per request by monthly request volume, then applies the standard per-million-token prices in the TopicVerge comparison dataset. Input and output are separated because output tokens are often priced differently and can dominate the bill for long answers.
The result is a planning estimate, not an invoice. It excludes cached-token tiers, batch discounts, tool calls, retries, image or audio charges, hosting, tax, and negotiated enterprise pricing. Use a production sample to estimate tokens, model retry rates separately, and confirm the provider’s current price page before making a budget decision.
