Yep. Even ignoring the "fixed costs" of insurance, tax, and part of the depreciation, servicing intervals will be reduced, tyre replacement will increase, and the journey time may not be quite as reliable as journey planners may suggest. I would also query 15km/litre in the real world - unless you are driving a hybrid, or sticking rigidly to 90km/h or thereabouts on the M7 which I find unlikely. Traffic queues in Dublin would also seriously increase fuel use due to stop start driving.
The cost I worked out was to compare the ticket costs with the UK, to refute the "over-charged" element of the post I quoted. 47 weeks was used, not the 48 you have used, on the basis of 4 weeks annual leave, plus bank holidays, which is the norm.
If you can get to work on the 92, use a bike. I do when working in a city centre office - it takes 10-15 minutes to get to Stephens Green or the ILFC. If I have to go to Dundrum or Stillorgan, I cycle to the Green and get the LUAS. Cycling costs nothing apart from a squirt of oil and new brake pads every now and then.
