What is the cost of BIM license?

Excuse me, could you please clarify the pricing structure for acquiring a Building Information Modeling (BIM) license? I'm interested in understanding the total cost involved, including any upfront fees, annual subscriptions, or additional charges that might apply. Is there a pricing tier system based on the size of the project or the number of users? Additionally, are there any discounts available for educational institutions or startups? Your insights into the financial aspects of BIM licensing would be greatly appreciated.
