The quality of your voice over depends almost entirely o the skill of the voice actor you use. A good voice actor will have perfect enunciation (ie, be very easy to understand), speak at an ideal pace (not too fast and not too slow), and have a pleasing voice. They should also be good at acting, and able to convey the feeling or emotions required by the script, using vocal variance and tone to keep the words interesting while also embodying the desired mood.
When considering “how much do voice actors make”, you have to consider the physical demands of the job. A voiceover actor’s main tool is their voice. Unlike a machine, the voice is a sensitive instrument and cannot be used to extremes all day, every day. If you did, you would risk damaging your vocal chords. Of course delivering the same consistent quality 12 hours a day would also be impossible. For many established voiceover talent, even long periods of use, 3-4 hours at a stretch can be tiring. At the extreme vocal end of voice acting you have gaming. In gaming the physicality of shouting and using the full range of voice, often for different characters takes it’s toll. For this reason many gaming voice actors are particularly careful about their vocal health.
One of my favorite things about being a voice-over actor is the incredibly supportive community. Use your community to communicate with other voice-over actors regarding rates and best business practices. I have rarely found anyone who is secretive or not willing to share their past experiences. By being a generous and communicative community, we are stronger as voice actors and can advocate for ourselves to get paid appropriately. If you are operating from a home studio and all communication is between yourself and the client (versus an agent as the intermediary) it’s usually your responsibility to invoice after sending your VO files. I always include a polite 30-day payment term at the bottom of my invoice. In certain states (for example, New York) there is a “Freelancing isn’t Free Act”, in which you can politely mention to be paid in a timely manner.
Always update yourself on industry standard rates. I recommend reviewing the union rates set forth by SAG-AFTRA. Voices.com also offers a rate card as well Voice-Over Resource Guide. Upon viewing these rates you may find, based on your current experience, you fall a little lower or higher than said rates. Maybe you have a great deal of experience in the commercial voice-over world, but now you’re branching out into narration, e-learning or audiobooks, so your voice-over rates may be a bit lower for that genre as you find your footing. The most important thing is that you have a baseline rate for yourself and you’re comfortable and confident stating this rate to a client. It’s beneficial to first ask your client’s budget and proceed from there. While stating your rate, also take into consideration edits and pick-ups. It’s customary to include one free round of edits in your rate, but any edits or pick-ups past that incur a fee.
