RunTheNumbersAI helps you make AI cost decisions based on how you actually use tools like ChatGPT – not pricing pages or marketing tiers.

Our calculators estimate real monthly costs using message volume, response length, model choice, and setup type, then give a clear verdict when there’s a better option, or confirm when your current setup already makes sense.
