The average podcast episode lasts around 40–45 minutes. With an hour of dead time a day you could listen to well over 400 episodes a year – enough to work through several back catalogues or learn a new subject.

Inputs explained
| Field | What to enter |
|---|---|
| Travelling / commuting | In min/day |
| Household chores | In min/day |
| Exercise | In min/day |
| Other “dead time” (queues, walking) | In min/day |
| Listening efficiency (attention) | In % |
| Playback speed | In × |
| Average episode length | In min |
What each result means
- Effective listening per day = ([Travelling ÷ commuting] + [Household chores] + [Exercise] + [Other “dead time” (queues, walking)])×[Listening efficiency (attention)]÷100×[Playback speed]
- Episodes per week = [Effective listening per day]×7÷[Average episode length]
- Episodes per month = [Effective listening per day]×30.44÷[Average episode length]
- Episodes per year = [Effective listening per day]×365.25÷[Average episode length]
- Listening hours per year = [Effective listening per day]×365.25÷60
Example values
How the main result changes when Travelling / commuting changes and everything else stays at the example values above:
| Travelling / commuting (min/day) | Episodes per year |
|---|---|
| 25 | 764 |
| 37.5 | 871 |
| 50 | 977 |
| 62.5 | 1,083 |
| 75 | 1,189 |
| 100 | 1,402 |
Formula
Listening per day = dead time × attention × playback speedEpisodes = listening time ÷ episode lengthWorked example
Inputs — Travelling / commuting: 50 min/day; Household chores: 30 min/day; Exercise: 20 min/day; Other "dead time" (queues, walking): 15 min/day; Listening efficiency (attention): 80 %; Playback speed: 1.25 ×; Average episode length: 43 min.
Results — Effective listening per day = 115 min; Episodes per week = 18.7; Episodes per month = 81; Episodes per year = 977; Listening hours per year = 700.
