Podcast Storage
Size up a podcast hard drive from episodes, length and bitrate.
About Podcast Storage
Each episode's megabytes come from its length and encoded bitrate, and multiplying by episode count sizes the finished archive. Keeping source files and stems on top of delivery MP3s can triple drive needs, so totals should include the working copies.
Formula
Podcast Storage
Episode = minutes x bitrate x 60 / 8000; archive = episodes x episode size
- kbps
- Kilobits per second of delivery audio

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
