Americans who once drove to work are saving an estimated $758 million a day since the onset of the Covid-19 pandemic, according to a new study by Upwork economist Adam Ozimek.

That collectively adds up to an overall economic impact of almost $91 billion, the study by the freelancing platform found. The savings are broken down into into several categories including direct costs and time value, with the latter producing the greatest economic benefits. Putting a modest value of $12.50 an hour on time spent commuting by car, Americans collectively are saving $411 million a day by staying home.

Fewer trips to gas stations and repair shops add another $183 million in daily savings. Reduced accidents, pollution and other social impacts contributed $164 million more, according to Ozimek’s research, which draws from several economic studies including a 2019 AAA report on the costs of commuting.

The bottom line for Americans who drove to work before the pandemic: Each commuter has saved on average more than $2,000 so far by working remotely since mid-March, he said.

Commuters saved over 70 minutes per day in locales such as New York City, Washington D.C. and San Francisco.
