The approximate costings for all referenda since 2001 are set out in the following table with the exception of the referenda held in 2004 and 2011*. The referenda in those years were not taken on their own but were combined and accounted for with European and Local Elections in 2004 and with a Presidential and bye-election in 2011. It is not, therefore, possible to give an accurate cost of the referenda as there would have been an extensive sharing of staff and facilities for the different polls taken.

The costs of holding referenda, while significant, have been reduced since 2008. The estimated cost of the referenda (Marriage Equality & Qualifying Age for the Presidency) in May 2015 is c.€15 million. However if these referenda are held in conjunction with the forthcoming bye-election it will be more difficult to isolate the actual cost of the referenda as staff and facilities are shared in the taking of polls and in the counting of votes.
