The last 29 days, I just checked, I am paying 19 CAD for 143kWh. https://forums.macrumors.com/attachments/screen-shot-2016-10... shows 4W but perhaps it's 4.6W because of the brick efficiency. Since this thing was running 24-7, that's 29*24=696 hours so we are looking at 3171 Wh or 3kWh. At the end, (4/.878 x 696/1000)/143
x 19 x 4 x 365/29=21.210 so we that's 21 bucks and change.

1000 convert to kilowatt
per current monthly kilowatt to get to the fraction of consumption
times the cost of monthly consumption
the replacement battery and the guy doing the replacement, yeah that was a hundred alas. Oh well.
times four years
times the fraction of a year that monthly consumption comes to
