watts converted to dollars

GW

I asked this question a couple of months ago; and the answer was so easy i thought I'd remember it! Well i forgot... I'm past my youth I suppose.

Can anyone tell me the formula again? I'll be sure to type it into my smart phone's notes.

so, if I'm paying 18 cents a KW, and the circ is 80 watts running non-stop, how do i do the math?

Thanks, gary

Formula

80 watts/1000 x $0.18 x 24hours x 200days = $69.12

Rate question...

Gary, when you say 18 cents, is that taking the total bill and dividing it by the kilowatts? If part of that bill is for standard fixed monthly charges, you have to exclude that portion or your rate will be overstated. If 18 cents is your current variable portion you have my sympathy.

Rate for KW

Uni,

I'm not sure what you mean re his fixed KW expenses. To figure out his total bill for KW he must take the bottom line on the bill, and divide that by the KW.

The electric Co would like you to do otherwise, because it makes their rate look better, but the bottom line is he pays the entire bill, for the total KWH consumed.

If you oil company charges you $2.30 per gallon of fuel oil, and then separately charges you a $00.35 fuel delivery excise diometric surcharge, (or some other ridiculous name) you are paying $2.65 per gallon for fuel, period.

No different for his electric, with all of the little diddys and dattys that the electric company heaps on to your bill.

An oil company charges a price per gallon. But if your oil company charged you $2.30 per gallon of fuel oil, and then separately charged you on the invoice a $00.35 fuel delivery excise diometric left handed surcharge, (or some other ridiculous name like the electric company uses) you are paying $2.65 per gallon for fuel, period.

No different for his electric, with all of the little diddys and dattys that the electric company heaps on to his bill after the KW charge. He has to figure them ALL into the total KWH price.

I mean he'll save less than $69.12 over 200 days.

That's what I mean by overstated. He will save less - he can only save on the variable portion of his bill.

If his normal bill is $100 and $30 is the monthly hookup fee he'll pay that same fee regardless of how much or how little he uses. As he uses more, his rate will appear less as more and more kilowatts spread out the fixed cost.

Anyway, if $30 is the fixed cost portion then he'll only save 70% of the $69.12 (which is $48.38).

Your oil example is fine, $2.65 would be my price too but I wouldn't be adding in a fixed monthly rental for a oil fired water heater. Flat fees have to be excluded for the math to work unfortunately.

I'm slinging my work armor on; read the question but really didn't understand...the 18 cents is the total KW used divided out of the dollars spent (did I phrase that correctly?). Yes, it's very high.

Thanks for the math formula.
