How much does it cost to run my hot water heater? Approximately 14 cents per kWh. How much does it cost to run my AC? Approximately 14 cents per kWh. Same thing with all my appliances, including my electric golf cart. I can’t prioritize one over the other since I need to use them all and can’t decide which kWhs go where. It really doesn’t matter in the big picture since electricity is relatively low cost here. Our electricity usage varies by a factor of 3x during the year but the cost per kWh stays pretty close to 14 cents per kWh. How many watts- hours per mile for my gas cart and how many miles per gallon for my electric cart is really not important. The electric cart is lower cost but it is a matter of a small number for the gas cart being a bit smaller for the electric. We spend about $200 on gas for the gas cart and about $60 on electricity for the electric cart each year. In case you were wondering, the gas cart is used more.

Similar to the distinction between marginal tax rates and average tax rates.
If I am already in the highest tax bracket and want to know how much more in taxes I pay on the NEXT dollar of income, I want to use my marginal tax rate, not my average tax rate.
The reason for the particular analysis should determine whether you use marginal versus average.
Discuss.
