Is ChatGPT Plus or the API Cheaper for My Usage?

Compare subscription plans against pay-as-you-go API costs based on your actual daily usage. Prices updated live.

Should I pay for a subscription or use the API directly? It depends on how many messages you send per day and how long they are. This tool estimates your monthly token usage, prices it against each provider's live API rates, and compares that to flat-rate plans like ChatGPT Plus, Claude Pro, and Gemini so you can see which path is cheapest.
