Starting a podcast on Apple Podcasts is essentially free. Apple does not charge you to host your podcast on their platform. However, there are costs associated with creating a podcast such as equipment (microphones, headphones, etc.), editing software, and podcast hosting services.

Podcast hosting services are where your podcast files are stored and streamed from. These services can range from free to over $50 per month, depending on the features and amount of storage you need. Some popular hosting services include Libsyn, Podbean, and Buzzsprout.

As for equipment, you can start with minimal setup like a good quality USB microphone (around $50-$150) and a pair of headphones. As you grow, you might want to invest in better equipment and software for editing and improving the sound quality of your podcast.

So, while Apple Podcasts itself doesn't charge you, the overall cost to start a podcast can range anywhere from $50 to a few hundred dollars, depending on the quality and professionalism you want to achieve.
