When thinking a day at work versus a day not at work, the numbers can be somewhat staggering.
When I lived in New York, round numbers were about $300 a month for the train, $100 for the subway. Drive to the train was short, lets say 2 gallons per week. So, at gas price today, that would be roughly $110 a week or $22 a day for my transportation.
When I add in dry cleaning ($5 a day), and lunch ($15 a day), you are looking at about another $20 a day. Add a breakfast, a coffee or other drink, and you could easily be look at $25 - $30 a day.
Being out for a day did not change my transportation cost model much as those were monthly tickets. But I would save a few dollars on the daily lunch and dry cleaning expenditure.
Where I live today, my commute is 40 miles each way. Assuming my vehicle averages 20 MPG, that is about 2 gallons each way, or 20 a week. At $4.19 cost of gas in Charlotte, the would be about $17 a day. No longer need dry cleaning, but again, thinking $15 for lunch, and another $5 - $10 in snacks, drinks, the occasional girl scout cookie sale, and yes, lets call it $23 a day. Adding the gas, and we are at $40/day.
In neither situation did I mention the wear and tear cost of using the car. But, 80 miles at $58.5 cents per mile (IRS Number) comes out to about $47 a day. So adding $23 a day to the $47, that comes out to $70 per day.
Now, WFH changed all of that. Staying home, no need to drive. No need t go out and have a "social" lunch with my coworkers. No need to take a 15 minute break and walk over to the coffee shop with a few coworkers either. So saved a lot since the pandemic. We returned to the office this month. People are frustrated because they no longer get me at my desk at 7:00 AM or at 5:00 PM, because now I am spending an hour each way commuting. And now I appear to be spending more than ever...
