Sure, lets factor it in. Using my fuelly account I found out I average a 10.1 gallon fillup. A 20 cent difference in premium brings us to $2.02 per fill up. My fuelly says I average 6 fill ups per month but I've only had the car for a month and I did a LOT more driving than I usually would in a month. Nevertheless, that high average brings us to 72 fill ups/year. Over a year I spent $145.57 more in petrol so I could have premium (going by averages here on prices too).
Now that's not a big difference, I'm paying an extra $0.40/day to have premium. No offense but this would basically make you a complete cheapskate if you think paying an extra 40 cents a day is something that is even worth these calculations.
But hey lets look at it like this, my previous car averaged 21mpg under significantly less aggressive driving than how I drive my BRZ. My average fill up was 15.5 gallons of regular old gas which I've seen at around $3.33 in my area right now. Assuming I still drove the same amount in my old car,
I am saving about $700/year by putting premium into my BRZ that I have FUN driving.
Check my stats if you're interested, I don't do ANY highway driving. My drive to work is from 6:50-730am and home is around 4:00-4:45. Pretty high traffic times in my area. These numbers would all be even better if they weren't for traffic.
