As you can see, there is really no clear answer as to what it will cost to start your podcast. Generally speaking though, you can expect to pay $200-$500 for a good quality podcast. On the extreme ends, you can start a decent podcast for around $100 and for the best of the best, most professional podcast possible, you can expect to dish out around $5,000.
