Which Calculator to Use
For a quick, single-rate estimate, use our Token Pricing Calculator; for a more precise estimate accounting for separate input/output pricing and request volume, use our LLM Cost Calculator.
Factors That Can Change Your Real Bill
Actual usage patterns rarely match a flat average — unusually long individual requests, retries after errors, and seasonal usage spikes can all push your real bill above a simple average-based estimate.
Building In a Buffer
Given the factors above, it's sensible to budget with some buffer above your calculated estimate, particularly in the early stages of a new AI-powered feature before you have real usage data.
