Calculate a Break-Even

How long will it take to make up the cost of buying a more fuel-efficient car?

(If you have a car you plan on selling.)
(How far do you drive to work? Then multiply by two.)

(E.g., number of days per month you commute.)


MPG stands for miles per gallon, a unit of measure referring (in the most common sense) to how efficiently a fuel-powered engine converts the potential energy of its fuel into distance traveled for the engine and its payload.

For our purposes, the payload is an automobile ("car") plus passenger(s), and the fuel is typically, but not always, gasoline.
