Ngige told labour leaders in Abuja that the sum was what would be needed by government to pay the consequential adjustments as demanded by labour.
Agency reports said that the minister’s announcement was the latest in the increasing drama over the payment of the new minimum wage.
A bill for the new minimum wage was signed into law by President Muhammadu Buhari on April 18.
Ngige was speaking when the leadership of the United Labour Congress paid him a courtesy visit in his office.
Government and labour have been locked in an endless tussle over modalities for the payment of the new wage, long expected by workers.
Ngige said that federal government was avoiding a situation where it would have to lay off workers.
The minister pleaded with labour to accept the consequential adjustment from levels 7 to 17, adding that government had only three months left to implement the new wage.
He stated that the government would not promise labour what it could not pay, noting that no worker deserved to be owed salary.
Ngige disclosed that the Federal Government had so far paid arrears of N500 billion to workers, including the Academic Staff Union of Universities.
He restated that implementation of the new wage had since commenced for workers on grade level 1 to 6, adding that the development had helped those on the lower cadre in the civil service to move up.
He said there was need to review obsolete laws that were not in tune with present realities, noting that a situation where some private sector employers paid their employees N10, 000 and N15, 000 was unacceptable.
