Households' total disposable income also increased by 5.9% from €111.97 billion in 2018 to €118.55 billion last year, mainly due to higher wages.
The CSO said the derived saving ratio - savings as a percentage of total disposable income - increased from 10.2% in 2018 to 10.9% in 2019.
Today's CSO figures also show the Government's gross saving stood at €10.29 billion last year, up €2.87 billion on 2018.
