Methodology: From Usage Inputs to Monthly Cost Scenarios

This page exists to make the estimate explainable to stakeholders.

Build scenarios

What the estimator models

  • monthly volume from DAU and request frequency
  • output size via response length bands
  • scenarios (base/high) to reflect uncertainty

What it does not claim

  • It does not predict usage; you provide assumptions.
  • It does not replace production monitoring; it supports budgeting decisions.

Pricing updates

We maintain model price data and apply updates so estimates remain relevant. We regularly check provider API pricing pages.

Frequently Asked Questions

Why do you use response length bands?
Exact token counts are hard to predict. Bands (Short, Medium, Long) provide a robust enough range for budgeting.
How accurate is an estimate without token-level inputs?
It is an estimate for budgeting, not a billing statement. It provides the order of magnitude and variance.
How often are prices updated?
We review and update prices upon major provider announcements.
