Much less than the fuel for the car, likely even less than the electricity for an electric car.
Road bike tires (the only kind you should use for commuting on paved roads) last between 2500 and 6500km. If you don't skid while braking (which you shouldn't ever do anyway) and use the correct pressure it's easy to push that figure towards the top of the bracket.
Disk brake pads last between 8000 and 16000km.
Tubes last between 1500 and 8000km.
The chain lasts between 3000 and 5000km, and shifting correctly makes them last a lot longer.
If you shift correctly and replace the chain in time, the sprocket never wear out. I had a road bike from the 70s that I used quite heavily for about 10 years and it still had the original sprockets and shifters.
Pedals, cranks and bottom bracket also only fail if you abuse them (e.g. never shift).
Which leaves the pull wires (for breaks and shifters) and the grip tape, which both last very long and are very cheap.
All other parts only break when abused or in an accident.
So if we say you are commuting your bike and it's 50km per day, 5 days a week without counting vacation and stuff, then that's 13 000km.
That means:
Prices are name-brand products from Amazon.
That's €163 in total. You could probably even go cheaper than that, and 50km per day is quite a lot as well. If you take care of your bike, you can push the components much farther too, since I only took the average values.
A more likely value if you are careful while riding and maybe only commute 20km/day, you probably won't have more maintainance cost than €40-50/year.
