Increasing all the main weekly personal rates of social welfare in October's budget by €1 would cost the exchequer an additional €71m a year.
A paper by the Tax Strategy Group (TSG) at the Department of Finance also shows a €1 increase in the weekly personal rates of all social welfare schemes, with proportionate increases for adult dependents, would bring the extra bill up to €76m per annum.
In this year's budget, which was announced last October, weekly rates of social welfare payments were increased by €12.
The TSG analysis also shows that if a €1 rise for child dependents and a €1 hike in supplementary payments, including living alone allowance and fuel allowance, were also added to the above increases, the additional cost overall to the State would be €127m a year.
It also explains how increasing the monthly rate of child benefit by €1 would cost a further €14.8m a year.
The paper also details how a €1 increase in the weekly personal rates of all social protection schemes, with proportionate increases for adult dependents and a €1 increase in the monthly rate of child benefit would cost €86m.
While a €1 increase in personal rates of all weekly paid schemes, with proportionate increases for adult dependents, a €1 increase for child dependents, a €1 increase in supplementary payments including living alone allowance, fuel allowance and over 80s allowance and a €1 increase in the monthly rate of child benefit would result in an additional annual bill of €142m.
A double weekly payment, like that provided through the so-called "Christmas Bonus", would cost €350m if given to all those who received it in December, along with those receiving illness payments for over 12 months and the Working Family Payment.
An additional week of Fuel Allowance payments, which would reach over 400,000 low-income households on long term social protection payments, would cost €14.7 million, the report adds.
In its Summer Economic Statement, the Government said a further €6.9bn in spending would be included in Budget 2025, which would include any increases in social welfare.
Budget 2024 was, for the second year in a row, the largest social protection budget in the history of the State, the paper also says.
The TSG paper also outlines how since the outbreak of war in Ukraine, more than 103,000 PPSNs have been issued to Ukrainian people seeking protection here.
Three quarters of these are women and children and approximately 80,000 remain in Ireland.
It says more than 8,000 Irish families hosting over 17,000 Ukrainian refugees currently are in receipt of the the Accommodation Recognition Payment.
