Taoiseach Micheál Martin and his senior team of ministers will cost an extra €50,000 over a full five years in government.
The changes in ministerial pay will mean Mr Martin, Tánaiste Leo Varadkar and other senior ministers cost the taxpayer €10,000 more per year than the same roles in the former Fine Gael-led minority government.
It comes as three super junior ministers at the centre of a controversy over a salary top-up agreed to gift the allowance back to the State.
They agreed to combine the two existing allowances together and divided it between the three of them, which means they will each receive a top-up of around €11,000.
The Taoiseach revealed what he described as a 10pc across- the-board pay cut for ministers amid the storm over the top-up for super junior ministers Jack Chambers, Hildegarde Naughton and Pippa Hackett.
However, the last government had been waiving pay restoration increases that had been due to ministers in recent years.
That means the 10pc cut announced by Mr Martin to the official salary rates still leaves senior ministers better off in terms of take-home pay compared to the last administration. Mr Martin was forced to defend the move in the Dáil.
Sinn Féin leader Mary Lou McDonald criticised the situation, while Rise TD Paul Murphy claimed it was an "utter joke" and asked Mr Martin whether he agreed it was time for "sky-high" pay for the Taoiseach and ministers to end.
Mr Martin said he would be "gifting back" around €25,000 to the State as a result of the Cabinet decision.
This takes into account the waiving of a 2pc increase due to ministers in October.
Mr Martin said: "I have no difficulty in doing that. I'm happy to do that."
He said he previously took a "significant cut in pension" in 2010 and also gave back a severance of around €80,000.
He disagreed with Mr Murphy on lowering pay for TDs, arguing that it ultimately led to wealthier people entering politics or benefiting richer parties.
An Irish Independent analysis of the changes to ministers' pay shows that in total Mr Martin and his senior team will cost €10,092 more per year than the corresponding roles in the last government.
Mr Martin will get €186,831 - almost €1,500 more than the €185,350 Mr Varadkar was being paid during his time as Taoiseach.
Mr Varadkar is to be paid €172,263 - almost €1,000 more than the €171,309 his predecessors were paid in the same role.
And other senior ministers, including Green Party leader Eamon Ryan, are to be paid €158,129 - almost €600 more than the €157,540 that senior ministers took home during the last government.
Ministers joined Mr Martin in defending the changes to pay. Mr Ryan said he hadn't known how ministerial salaries compared with those of the last government when the Cabinet made a decision to hand back 10pc of their pay.
He denied the move was tokenistic, despite it leaving some ministers and the Taoiseach better off. He argued the cut that was decided would result in around €600,000 being returned to the State each year.
Public Expenditure Minister Michael McGrath said what the previous government had done was "very complicated" and it was "far simpler to take a cut off the official salary". He told Cork's RedFM: "I'm certainly not there for the money and never have been."
