What’s the average cost of a consultation with a lawyer?

I'm just starting to explore my legal options, however, I'm worried about the expenses. What’s a reasonable amount to expect to pay for an initial consultation? I understand rates vary with experience and specialization. Still, I'd like a general idea. Are there any situations where a consultation is typically free? Does location affect the average cost? I'm trying to budget and what's the average cost of a consultation with a lawyer might be.
