They say the average person owns a car for 5 years, therefore, that is the amount of time that you use to calculate the cost savings of a hybrid. But that is baloney. There looking at whether its worth it for the average user to buy one. From that perspective it makes a lot of sense to consider the average period of ownership. The specific figures aren't directly applicable to your plan, but they give a good start. The 2nd study concluded it would take ten years to make up the difference in costs, but it didn't include the time value of money, and it didn't include the cost for battery replacement. If you do calculate based on a 15 year lifetime than you probably have to include the cost of replacement batteries. Also the studies were comparing buying a new non-hybrid vs. buying a new hybrid. They didn't include additional costs for "flex-fuel" and "plug-in" and more importantly they didn't include junking an existing car. They only included the incremental cost of the new hybrid over a comparable vehicle. They didn't calculate the cost of a brand new car. If it takes 5 or 10 or 15 years just to deal with the difference in price, how many years does it take to deal with just paying for a new car (or half of one) perhaps an infinite number of years. In other words when you consider the time value of money you never make up the difference.
