For OP, to catch 23:55 flight, its more likely to be base fare +25% ... so about $20-22 ( + $3 surcharge for picking up in CBD). Shouldn't be ERP at that time of night. So all up around $25.
You can easily use the MRT at this hour. It shouldn't be too crowded and you need to go to the airport before the MRT system closes for the night. This avoids the anxiety of getting a taxi in the evening, when there can be long waits at hotels, for instance.
