What would you do with an extra $345 a year?

One smart move would be to invest it. If you managed 7 percent returns over 25 years, you’d have around $23,600 more to enjoy in retirement. But instead, the average American is blowing that money looking for parking.

On average, drivers in the U.S. spend 17 hours a year searching for parking, according to a recent Inrix study. This results in a cost of $345 per driver each year in wasted time, fuel and emissions. Collectively, the cost is $72.7 billion annually.

For the study, Inrix combined data from its parking database and a survey of about 6,000 U.S. drivers. The traffic data company’s chief economist, Graham Cookson, describes the study as “the first ever study to quantify the economic and non-economic costs of parking pain.”

Inrix contends that the economy bears the brunt of our parking problems. Inrix found that U.S. drivers cite lack of parking as a reason that:

• 39 percent avoided shopping destinations.

• 27 percent didn’t drive to airports.

• 26 percent skipped leisure or sports activities.

• 21 percent avoided commuting to work.

• 20 percent did not drive to the doctor’s office or hospital.

Parking troubles also cost drivers in other ways:

• 61 percent felt stressed.

• 42 percent missed an appointment.

• 34 percent abandoned a trip.

• 23 percent experienced road rage.

In some cities, the toll of searching for parking is much higher than average. It is highest in:

1. New York City : The average driver spends 107 hours per year searching for parking, costing them $2,243 per year.

2. Los Angeles : 85 hours, $1,785

3. San Francisco : 83 hours, $1,735

4. Washington, D.C. : 65 hours, $1,367

5. Seattle : 58 hours, $1,205

6. Chicago : 56 hours, $1,174

7. Boston : 53 hours, $1,111

8. Atlanta : 50 hours, $1,043

9. Dallas : 48 hours, $995

10. Detroit : 35 hours, $731

So the next time you’re about to pass up a parking spot and circle the lot or block once more in hopes of finding a better spot, think about that extra $23,600 you could have in retirement. Settling for the first spot might not seem so bad.

Using a smartphone navigation app is another way to help reduce the amount of time and money you waste searching for parking. Cookson notes that Inrix provides data to Waze, a free traffic and navigation app available for Android and Apple devices.

Google also has a “popular times” graph feature that can show you when a business is most and least busy. For example, if I search for my local warehouse club, I can tell it is generally a zoo between noon and 5 p.m. on Saturdays and Sundays, so I avoid going during those times.
