If you search enough you will find the answer, and it is not much even for a 1.100 wort. It doesn't even make up for the decrease in boiling temp. for where I live (at the nose bleed altitude of 900 ft above sea level).Several factors contribute, including:
Hmmm, something I've never considered. How does starting gravity affect boil off rate?
Dissolved sugars raise the boiling point of water, so higher gravity means the temperature of the boiling wort is higher. I was trying to figure out how much higher, but can't find a reference.
