About this author:

Thanks to an anonymous comment for the link to this Dept. of Energy website with data on the Average Price of a New Car from 1970 to 2006, in both current and constant dollars. The chart above shows the real, inflation-adjusted average price of a new car from 1976 to 2006 (in constant 2006 dollars).

What's interesting is that the real price of a new car fell by 10% from 1998 ($25,186) to 2006 ($22,651), and decreased in 7 out those 8 years, or by a total of $2,535 during that period.

Note that this measure of retail car prices does NOT adjust for the continual quality improvements over time in new vehicles, while the CPI: New Cars measure does (see below).

 

In the face of all of the bad news about rising gas prices, here's maybe some good news: The real cost of new cars is actually declining.

Here's why: In the last 30 years since 1978, consumer prices on average [CPI: All Items] have increased by about 3X (see chart above). During that same period, the CPI for Gasoline Prices has increased almost 6X, meaning that the real cost of gasoline has risen. But the CPI for New Cars has only gone up by less than 2X, meaning that the real cost of new cars has been falling, offsetting some of the sting of higher gas prices for consumers.

On an average annual compounded basis, consumer prices have increased annually at a 4.1% rate since 1978 (see chart above), while gas prices have increased by 6%, meaning that the real cost of gasoline has been rising by 2% per year on average over the last 30 years. But the cost of new cars has increased by only 2% annually, suggesting that car prices adjusted for inflation have been falling on average by 2% each year since 1978!


Another way to look at it: If new car prices had risen at the same rate as inflation since 1978, new cars would be more than 50% higher than today's prices. And if new cars had increased annually at the same rate as gasoline prices, they be more than 3X higher than current car prices! If the real price of gas is rising, but the real cost of new cars is falling, is it possible that the overall cost of owning and operating a car might not be changing that much?

Update: IRS guidelines allow 50.5 cents per mile deduction for vehicle expenses in 2008. At 12,000 miles per year, 25 mpg and $4 gasoline, that works out to about 16 cents per mile in fuel costs, leaving 34.5 cents for non-fuel related expenses. In percentage terms, that's 32% for gasoline and 68% for non-fuel expenses, including the cost of the vehicle, financing, depreciation, etc.

    Could the rise in gasoline prices and how it relates to the cost of a new car be the same thing as how higher interest rates lower housing prices? I'm a finance novice. I just recently found out about the relation between mortgage interest rates and housing prices. This made me think about all the really cheap pickup trucks that seemed to go for $25k + a few years ago but are now selling for $15-17k. This is just anecdotal evidence, but I realized that a person's monthly car payment could have easily doubled in the past few years if they got one of these pickup trucks or SUVs combined with a commute in from the 'burbs. Could the rapid rise in gasoline prices pinch dealerships' and the automakers' bottom line because people just can't afford a $299/month car loan plus the unplanned $300 for gas/month?

    Like I said, anybody who believes govt numbers or touts them as gospel is either out of touch or things that you are. Nobody with their eyes open can tell an honest many that the price of a new S class Benz is lower in inflation adjusted price today than it was in 1978

    Dear Professor. Please explain the suggestion that the "real" price of cars is somehow less than their current prices. You are either terribly confused or else you are looking for suckers. Real pricing is what we pay.Using a govt rigged index does not cause the car dealer to sell us a car for any less than the market.

    Your suggestion that somehow cars are cheaper does not conform with your admission that purchasing power has eroded over the years. You somehow suggest the impossible as a benefit, i.e., if there was no inflation, then cars wouldn't cost so much. Duhhh !!! No wonder they call Econ the dismal science. Truth is they massage the numbers to give the result the want to push. When Nixon got 200 of them together to figure a policy, they could not agree.

    Very interesting article indeed. Thanks for the info.

    To proseadvocat:
    Isn't the usual knock against the govt CPI number that it is too low, thus UNDER-reporting inflation? If the real CPI is higher than what is reported, then cars are even cheaper now than stated in the article, using inflation adjusted numbers of course.

    Suppose Americans have been purchasing more "econo" cars and fewer luxury cars. How would that affect these numbers?

    proseadvocat, you are making zero sense.

    I'll bet you are one of those folks that thinks inflation is really 10%. Of course, if that IS true, then the real cost of a car is even LESS now compared to the cost in 1980. You cannot have it both ways.

    Add in the fact that any car you bought in 1980 was LUCKY to last 5 years without needing significant repairs (>20% cost of the car), and a car today will easily go 8 or more years without needing such repair and the TRUE cost of a car now is MUCH less than it was then.

    But if that IS true, and the government includes that in the calculation of inflation then inflation might ACTUALLY be lower than all the ten percenters think. BLASPHEMY!

    It doesn't sound like you have had many car repairs done over the last 8 years or more. Not only has there been a huge increase in cost, but car repairs have become much more specialized. Try taking your car to the neighborhood mechanic for major repairs. In most cases they will send you to the new car dealership's service dept. Take your life savings with you! If you really want to have a heart attack, get a price on auto body work. By the way, auto body work although inconsistant, is a very real expense of owning an automobile. To further complicate matters (in the opposite direction) consider that auto manufacturers since about 2007 have increased their warranty periods. Finally, domestic auto manufacturers have cut way back on the (very) low profit margin sales to rental fleets. In the very near future this will influence new (& used) auto prices upward. I can elaborate on that if you would like. Finally, all three domestic manufacturers are hurting right now, however, contrary to some popular belief, it is not because they are selling inferior products (like they did in the 70,s and going into the 80,s. They have been strangled by employee benefit packages & wages. That's changing, too. So the domestics are going to have to raise prices and profit margin or become extinct. It therefore becomes a more complex matter, however, I am of the opinion that real car prices will move up dramatically as soon as the consumer finances and borrowing power have recovered.

    The car is more computer than anything else and thus subject, in part, to Moore's law. Further, we're starting to see the elimination of much of the union cost from the structure so pricing can continue to be more flexible but yield additional marginal profit.

    I agree with chuckp. The costs of car ownership have been somewhat backloaded. Cars are engineered in ways that make them as cheap as possible to assemble; it seems little regard is given to the cost to repair them.

    This just shows how gas has affected the price of goods. As the overall price of oil rises companies aren't able to sell their larger vehicles like they once were able to.
