The savings come from avoiding repeated trips

A commute is more than time spent traveling: it creates costs that recur each day someone goes in. Driving adds fuel and wear to a vehicle; public transit requires fares. Going to an office can also make convenience spending more likely, such as buying coffee or lunch nearby. Remote work removes many of these workday-triggered expenses because the employee no longer has to travel to perform the same tasks.

Some savings are immediate, while others build gradually. Fuel or transit spending can fall as soon as office trips stop. Lower mileage may also slow the need for maintenance, though it does not eliminate the fixed costs of owning a car, such as insurance or a loan payment. The difference matters: remote work can reduce the cost of using a vehicle without making vehicle ownership itself unnecessary.

The bill does not disappear; some costs move home

Working at home can use more electricity, heating, cooling, and internet capacity during the day. A worker may also need a desk, chair, or other equipment. Those costs vary with the home, the job, and what an employer provides, so the change is not a pure saving for every household.

The basic economic tradeoff is a shift in where work-related costs land. Employees often avoid recurring travel and convenience expenses, while households absorb some of the resources needed to make a home suitable for work. The net benefit is greatest when avoided office costs exceed the added costs of working at home—and when the commute would otherwise have been long or expensive.
