Hi @Md. Fahad Hasan Bhuiyan Emon , from what I can see it does appear that the fee per user doesn't appear on the calculator. I believe that is because it's not a consumption-based billing model, such as what appears on the calculator. Since cost is based on users with the plan, it's easy to know how much you're spending.
Please let me know if you have any questions and I can help you further.
