Playlist Duration
Total the runtime of a playlist from track count and average length.
About Playlist Duration
Each track contributes its average length plus a small playout gap, so the playlist time equals the product with track count. Planning setlists or radio hours needs a runtime that includes dead air, not just the sum of song lengths.
Formula
Playlist Duration
Total = tracks x (avg length + gap)
- gap
- Crossfade or silence after each track

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.
