Does Being Green Make Economic Sense? – Part 1 – Green and Hybrid Automobiles

It is clear these days to most people that being “green,” or living in a way that is not harmful to the environment, is the appropriate course and absolutely the right thing to do.

However, are we at a point yet that it makes sense economically to do so? In other words, are you punished economically by your urge to live properly?

In my opinion, if being green is truly ever going to be adopted by the majority of the population, it has to be made financially beneficially to do so (even though I wish it weren’t this way – it is just the way things are).

In this series, we will go through several analyses to take a look at if you are rewarded financially (or at least not punished by spending more) for living “green”.

Today, in Part 1, I want to take a look at the interesting subject of if buying “green” / hybrid cars is financially equivalent, more expensive, or less expensive than buying a regular gas-powered car.

To perform this analysis, we’ll compare three new cars – a Toyota Prius, a Toyota Corolla, and a Toyota Camry.

How does purchase price compare?

To start off, let’s get an idea of how much each of these cars costs.

After examining the prices at the links below from for the most basic models of all of these cars, we find the results below.

  • Toyota Prius II = $22,800
  • Toyota Corolla = $15,450
  • Toyota Camry = $19,595
    • It is also interesting to note that the hybrid version of the Camry is $26,400. Quite a bit more expensive than the regular car!

    Corolla Price and Gas Mileage –

    So, to summarize, it looks like we will have to spend an extra $3,205 to purchase the basic model of the Toyota Prius over the Camry and an extra $7,350 over the Corolla.

    How does the gas mileage compare?

    To see if this makes economic sense, we need to now know what sort of gas mileage each car gets. Using the references above from, we find the following gas mileage results. For simplicity, I have taken the average of the city and highway gas mileage rated by the manufacturer.

    • Prius average city/highway gas mileage = 50 miles per gallon (mpg)
    • Camry average city/highway gas mileage = 28 miles per gallon (mpg)
    • Corolla average city/highway gas mileage = 31 miles per gallon (mpg)

    Do you get any tax benefits or other financial bonuses for owning a green car?

    As a matter of thoroughness, I also want to make sure to include any kind of bonuses you get from owning a green car (tax credits, etc).

    I was fairly disappointed to find out that the tax credits you are eligible to receive from purchasing a hybrid vehicle are becoming less and less common.

    In fact, according to the links below, the Ford Fusion and the Mercury Milan hybrids were the only cars that were eligible for a tax credit in 2010. The Prius has not been eligible for this credit since 2004. Sad… – Hybrid Vehicle Tax Credits – Federal Incentives for Environmentally Friendly Cars

    How long would you have to own the Prius to break even financially?

    So, with no tax credits, we will have to rely on gas savings only to see if buying an environmentally responsible car makes economic sense.

    To analyze this, we’ll have to first lay out some assumptions to use.


    • Car will be driven 1,000 miles per month, or 12,000 miles per year.
    • The cost of gas is $2.50 per gallon.
    • Prius gas mileage = 50 mpg, Camry gas mileage = 28 mpg, Corolla = 31 mpg.

    Results of Analysis

    Due to the higher fuel economy with the Prius, given the assumptions above, it equates to a $472 per year cost savings in fuel purchases with the Prius over the Camry and only a $367 per year cost savings over the Corolla.

    With this magnitude of cost savings per year, it will take almost 7 years of owning the Toyota Prius to break even financially over the Camry, and a whopping 20 years over the Corolla.

    The details of this calculation can be seen in the Google Docs spreadsheet below that I put together.
    Google Docs – Does it Make Sense Financially to Purchase a Toyota Prius or Camry?

    This is quite an unfortunate find due to the fact that after you have owned a car for 7 years (let alone 20 years), you are most likely getting ready and/or thinking about selling it.

    Bottom Line

    So, from today’s investigation, I think our findings can be summarized as follows

    • 1) “Green” cars are much more expensive than regular cars
    • 2) Even though hybrid cars get good gas mileage, it still takes quite a few years to recoup your investment
    • 3) Purchasing a “green” car does not make financial sense in 2010 unless you are able to receive a tax credit for doing so.

    Are there any other costs to maintain a hybrid car that I missed? Are there any other financial benefits of hybrid cars (tax breaks from government, etc) that I might have missed?

    If you performed an economic analysis similar to this when you bought a car, what was your line of thinking?

    Well written. My Prius was “gifted” to me, so getting a Prius was better for me financially than getting a Camry.

    Aside from the peace of mind and sense of giving back to the world that buying a green car gives you, being able to drive >400 miles on a 10 gallon tank is very convenient as well.

    Fewer stops at the pump saves you time; and time is money! 🙂

    Evolution Of Wealth says July 24, 2010

    I would actually say that a better comparison would be the Prius to the Corolla or the Camry to the Camry hybrid. That would really skew the numbers but might be a more accurate comparison when it comes to the size of the car and type of engines, etc.

    I think there a ton of ways to be green beyond buying hybrid cars. Our site writes a tip every day that has some sort of green impact that will 98 times out of 100 save you money directly (you pay less) or indirectly (less consumption and waste means you pay less for services with your tax dollars).
