Wikipedia gives bitrate for audio and video for each format, of which there are multiple for a given video resolution. Sum those, add about 20kbit/s to compensate for jitter and encapsulation overhead, and you'd have a decent ballpark.

For example, itag 22, 720p mp4 takes up to about 3 Mbit/s for audio and video together.
