The number of people who are left with €100 or less at the end of the month after essential bills are paid has risen to over 1.8 million according to a survey.
Half of all adults are also struggling to pay their bills on time, the survey by the Irish League of Credit Unions has found.
It said 42% of consumers have had to borrow money to pay bills in the past 12 months and only three in ten are able to save any money at the end of the month.
Levels of disposable income are also continuing to decrease with an increase of 35,000 since June in the numbers with just €100 or less at the end of the month, the report claimed.
The latest "What's Left" tracker survey also found that over half of people feel that the introduction of a property tax is unfair as they had already paid a property tax in the form of stamp duty.
Eight out of ten consumers are worried that they will not be able to cope with the increasing energy costs this winter.
The tracker also found 96% of consumers are worried about the impact the 2013 Budget will have on their incomes.
The survey was carried out last month and is based on 1,000 responses from adults aged between 18 and 65 years of age.
