Job cuts at RTE over the past six years have cost at least €70m, while the latest round of cuts will cost at least €25m.
Last month, the national broadcaster said it was seeking 250 voluntary redundancies over the next two years to cut crippling costs.
Since 2011, it has shed 350 permanent jobs in three voluntary exit programmes.
Based on an average payment of €100,000 in 2012, current costs could soar to more than €25m.
The figures are based on RTE's restructuring in 2011 and 2012. Among the big names to go were news anchorwoman Anne Doyle and chief reporter Charlie Bird.
A spokesperson said RTE had not yet announced details of the voluntary exit programme.
It is expected all those who leave will be replaced by staff on rolling or temporary contracts.
Last month, RTE director-general Dee Forbes said the broadcaster was operating with vastly reduced commercial and licence fee income - €330m compared with €440m in 2008.
She said RTE had been under-investing for nearly a decade and "that is unsustainable."
Meanwhile, with regard to the sale of nine acres of land at Montrose, which could yield €75m to use for investment and slashing debts, the spokesperson said the RTE Sports and Social Club will move to a new location to the rear of the Television Centre next year.
It was also confirmed that the location of the popular soap, Fair City, will stay on the campus, although it will move to a new location.
Fair City films in a number of indoor and outdoor locations throughout the Donnybrook campus, some of which are situated next to the proposed new location for the set.
There will be no disruption to the broadcast of the soap while the new set is under construction. "Details about the new set location for Carrigstown will be announced [shortly]," the RTE spokesperson said.
"Any development of land which has been put up for sale will be a matter for the new owner and will be subject to planning permission."
Work on a new entrance off the N11 is expected to start in the next few days, while the development of the new creche will be finished by January.
