This comes down to how quickly you can transcribe at home, how well you develop your "ear," and how much time and attention you are willing and able to commit to your transcription work. Of course, you also have to find the best-paying transcription jobs, and we help you with that.
I typically type anywhere from 80 to 90 words per minute (wpm). I sometimes make up to $30 an hour when there is a short deadline for a job and I need to rush that particular job. I make anywhere from $15 to $19 per hour, on average. Someone without a lot of experience or that is an entry level transcriptionist should still be able to make $8 to $12 per hour.
