Gross disposable household income increased by €194m to €24.8 billion between the first and second quarters of the year, according to new figures from the Central Statistics Office.
Meanwhile, household expenditure decreased by €288m to €22.3 billion over this same period, resulting in household saving rising by €482m in the quarter.
The CSO figures also show saving as a percentage of gross disposable income (the derived gross saving ratio) increased from 8.3% in the first three months of the year to 10.1% in Q2.

However, gross saving for the total economy decreased slightly between April and June, when compared with the same quarter last year, from €21.828 billion to €21.777 billion.
The gross saving of households decreased by €128m over this period and financial corporations also saw a fall in saving, however, the saving of Government and non-financial corporations improved between Q2 2015 and Q2 this year.
Gross saving of Government was €1.89 billion in the second quarter, an improvement of just over €1 billion on the Q2 2015 surplus of €844m.
The main contributors to this change were an increase of €522m in taxes paid on production and imports and an increase of €627m in taxes on income and wealth.
The CSO data shows a slight increase in the lending of Government, from €108m in Q2 2015 to €157m for the same period this year.
Elsewhere, net borrowing by the rest of the world from Ireland amounted to €3.4 billion between April and June, compared with a net borrowing of €7.2 billion in Q2 last year.
The net borrowing position reflects the level of gross saving in the Irish economy.
