It depends. Starting a podcast can be free. You can do everything yourself, or use free plans with popular podcast hosts like Anchor or Buzzsprout. You can record an entire podcast with just your smartphone/computer microphone, but the quality would surely be a bit poor when comparing to a real microphone. Many podcasters choose established podcast hosting companies, and this can cost anywhere between $10 to $20 a month (for individual podcasters). Beyond that, most podcasters choose to invest in a microphone, editing software, and other gear, but most are one-time costs. A complete custom website is essential for podcasters, and Podcastpage.io is among the cheapest and best website builders you can use for creating a podcast website.
