It probably depends a lot on your circumstances, location and other factors!
In my case, in Rīga (the capital of my country, Latvia), it was approximately:
- leave apartment at 7:45
- walk to stop in around 5 minutes
- wait 5 - 10 minutes for a trolley bus
- ride in it for 20 - 30 minutes
- walk from stop to work for 10 minutes
I think it averaged out to around 40 minutes per trip, and 1 euro per day, given a monthly ticket:

For comparison's sake, walking would mean upwards of 100 minutes for that trip.
Regardless of whether in a car, or using public transportation, coming home in the evening often included waiting in traffic jams for close to an hour. In comparison, when coming home before 4-6 PM, the streets were relatively empty and there were no such traffic issues. Fewer cars, fewer issues of that sort.
But what holds here true doesn't hold true elsewhere and vice versa. Once you go past a certain scale of the city in question, transfers and other complications become unavoidable. Just how much of an issue it is, depends on many other factors as well (car ownership cost, possibility of accidents, the disadvantage of not being able to easily transport things when not owning a car and so on, lack of freedom without a car, especially when you want to visit less popular rural areas).
Neither beats rolling out of bed at 8:45, turning on the computer and brewing some coffee or tea, doing a morning shower and "being at work" 10 minutes later, though.
