Fairly subjective question. IF I told you could get €750 in interest (before dirt) by putting 20K in INBS at 3.75% would you think it would be worthwhile opening a INBS regular savers account with a rate of 4.35%? Notwithstanding the couple of days interest forgone as the money moved from lump sum a/c to current a/c to regular savers a/c you’d earn about €789 interest (before dirt) between the 2 accounts. Is it worth going to the trouble of opening another account and moving money around (INBS have no internet banking) for €39 (€29.25 after dirt)? Well that's your decisions.
