How much does BIM software cost?

Could you elaborate on the pricing of BIM software? I'm curious to know if there are different tiers or packages available, and if so, what are the key differences between them? Additionally, are there any upfront costs or recurring fees that I should be aware of? I'm also wondering if the cost of BIM software scales with the size or complexity of a project, and if there are any cost-effective alternatives available for smaller-scale or budget-conscious projects. Ultimately, I'm seeking a comprehensive understanding of the financial implications of investing in BIM software.
