The cost of electricity to operate your oxygen concentrator may be a medical deduction for your tax returns. To compute the cost, do the following:
Look at the label on your concentrator. It states the number of volts and amps the concentrator uses. For this example, we will use 115 volts at 4 amps.
Then you calculate the number of kilowatt (KW) hours per year as follows:
1) Compute the number of watts
115 volts x 4 amps = 460 watts (W)
2) to convert this to kilowatt hours
460 W x .001 KW/W = .46 KW
3) to compute the number of killowatt hours used.
For this example, we are assuning that the concentrator runs 24 hours per day, every day of the year.
. 46 KW x 24 H/day x 365 days/year
= 4,029.6 KWH/Y
4)Multiply the above result by the cost per KWH for electricity.
You can call your electric company for the cost for your area.
Using 11.04 cents for this example (the average for all U.S. in 2010)
4,029.6 KWH/Y x $0.1104/KWY = $444.87 (the yearly cost)
Check with your tax preparer to see if this along with any other medical expenses which you pay for can be used in your US tax return,
