In 2 years and 60,000 km I have saved about $6,000 in gas and paid an extra $800 in electricity (~$1/day). I know this for a fact because I checked my gas receipts for my previous cars and electricity bills from before I bought my Nissan LEAF.

I drive 80-90 km per day and recharge overnight on an ordinary 110V outlet. It takse a few second to plug in and I sleep peacefully while it recharges.  Charging time is not an issue. Far more convenient than standing in the cold blustering dark winter nights for 10 interminable minutes pumping gas and swiping credit cards. 

I've driven a few beaters that have left me stranded. EVs simply do not have the hundreds of mechanical parts that can crap out in an ordinary car. Or the unreliable fuel gauge that let me run out of gas on a few occasions. That's why I always carry a cellpbone.
