ChatGPT pricing looks simple — until your usage grows.
This ChatGPT cost calculator estimates your real monthly usage cost across ChatGPT plans and API pricing.
Calculate your real ChatGPT cost
Compare ChatGPT plans and API pricing based on your real usage — messages, length, and workload.
Example: With ~25 messages/day across a small team and mixed usage, the API is often cheaper than ChatGPT Plus.

If usage grows, flat pricing can quietly become inefficient. This tool helps you catch that early.
This calculator doesn’t sell ChatGPT plans. Its goal is simple: cost clarity. Some users stay on a fixed plan. Others switch to usage-based pricing. Both are valid outcomes.
