I dont understand how much the premium will cost me

[Роман Яцина]

$120 per year, but I don't understand if it's per employee or per workspace (with unlimited employees)?

The prices on the website differ from those indicated in my profile

It would be $120 per year per billable user within that Workspace. Once you upgrade, the bill is automatically calculated taking into account all users.

However, that doesn't mean that all users have to be paid for as part of that bill. That depends on these criteria:

1. Members of the Workspace itself are always billable
2. Guests of the Workspace are billable if they are members of more than one board. If the guest is only on one board, they're free.

We have some more info on how this works here: https://support.atlassian.com/trello/docs/how-billing-works-with-trello-premium-and-standard/

If you'd like to see in advance how much it would cost to upgrade your Workspace, you can find that by going to the Workspace billing page. To navigate there, click on the down arrow next to "Workspace settings" in the sidebar, and then click on "Upgrade workspace." You'll be able to switch between monthly and annual billing on that page to see how much each option would cost for either Trello Premium or Trello Standard.

I have 1 user and 11 guests (employees)
$120 a year will my workspace cost?
My workspace guests (employees) won't pay anything?!

If the guests are on more than one board in the Workspace, they'll be billed at the same rate as Workspace members. If they're on just one board, they'll be free. If you scroll down to the very bottom of that page (the one you sent the screenshot from), it will show you the total price for upgrading your Workspace.
