How do you figure out the payback period of refrigerators??? (Guys please because this is for a proj due tom!)

Question

Enviornmental science paper, and I'm stumped

Answer 1

You can pay for a fridge in a year and that's about $1500. and electric costs about $250. a year, so say $1700. for the fridge in a year is your payback period--- where as a year of ice and styro chests about $1200. and money for gas another $600. a year so $1800. a year for that! and an upgrade from old fridge to energy efficient one would save about $150. a year so for a new one replacing old one pay back period would be 10 years, and new one to ice age would be one year not even!

Answer 2

You need a baseline, a 'standard` fridge.
Then calculate how long the added efficiency
of better fridge takes to save the difference in
cost of the fridge with the cost of the power saved.
If it's a commercial calculation, the interest payed
on the added cost would come into play.

Answer 3

secne-there is little difference in refrig's--if you pay-$4900.00--to $600.00--it would less then a year
