Whether you run a professional podcast or manage audio content for a company, transcription can be time-consuming. Knowing how many hours to set aside helps you budget and meet deadlines. This tool estimates transcription time using audio length, playback speed, and an editing factor for corrections or speaker labels.

The calculation is straightforward:

$A$ is the audio length in minutes, $R$ is the playback speed multiplier, and $E$ is the editing overhead factor. If you transcribe at normal speed and usually spend 20% extra time cleaning up mistakes, enter an editing factor of 1.2.

For example, a 60-minute interview played back at 1.25x speed with a 1.3 editing factor would take about 62 minutes to transcribe. Use the result to plan your schedule or decide whether an automated service might save time.
