Lower income households experienced inflation rates of up to 10.3% in June, according to estimated figures from the Central Statistics Office.
This compares to the annual Consumer Price Index (CPI) inflation figure of 9.1% for last month.
The figures show those in the highest income category had an annual estimated inflation of 8.2%.
"Each household has its own unique consumption pattern of goods and services and therefore its own personal experience of inflation," said Joseph Keating, Statistician in the Prices Division of the CSO.
"The updated research paper published by the CSO today attempts to take account of those differences between households and provides an estimated breakdown of the CPI results by household characteristics up to June 2022.
"This has been calculated by combining the CPI results with more detailed expenditure data from the 2015/16 Household Budget Survey," he explained.
The data shows that households paying a mortgage had estimated annual inflation of 8.4%, while for households that own their home outright, inflation was estimated to be 9.3%
Meanwhile, households that rent their home from a private owner had an estimated inflation rate of 9.4%, versus 9.9% for those renting from a local authority.
The CSO data shows that the cost of energy was one of the major drivers of inflation in the 12 months to June 2022.
Transport-related price changes were responsible for almost a third of the 9.1% annual change in the CPI, while electricity, gas and other fuels contributed more than another quarter of the change.
Compared with the June 2022 CPI figure of 9.1%, today's data shows that the annual inflation rate was 8.8% for urban households and 9.7% for rural households.
The figures also reveal that households where the household reference person is aged under 35 had estimated inflation of 8.8% and, where the reference person is aged 65 or over, annual inflation was estimated to be 9.8%
