The TV presenter says he would not stay as long with the show as his predecessors Gay Byrne and Pat Kenny, and he would also be willing to take a further pay cut next year if needed.
"I'm hoping to be there for the next three years and we will see what happens after that," the 39-year-old said.
As he begins his fourth year in the job, he confirmed that he has yet to sign his new contract with RTE -- but has accepted a "30pc plus" pay cut which will bring his annual pay packet below €373,000.
"I took the pay cut because I am a realist and know exactly where we are as a country in general and as an organisation in particular."
Asked if he would take a further pay cut next year, he replied: "I would roll with that entirely. I think presenters are very generously paid and that's the way it has been in recent years. I think the cuts are reflecting a more realistic approach to the payment of people like me. I would do whatever is required."
Tubridy's bright start to the latest Late Late Show series last Friday night with a coveted interview with Katie Taylor and the rest of the Olympic boxing team brought in 713,000 viewers.
It was slightly marred, however, by his repeatedly calling Olympian boxer Adam Nolan "Andy".
The Bray-based garda, who is best pals with training partner Katie Taylor, insisted Pat Kenny would never have made such an obvious gaffe.
He tweeted: "Bring back Pat Kenny, all is forgiven. At least he'd get your name right, Tubridy you Jerk! #AmateurHour #TakeItHandyAndy."
The Late Late Show scooped Taylor from colleague Miriam O'Callaghan who had hoped to interview her for her Saturday Night With Miriam programme.
"It was a great result for us and I was very happy with the groundwork that the team did in securing that story," said Tubs.
"I think the Late Late Show has the reputation for being the programme on which people come to say 'hello', 'goodbye' and 'thank you very much'. It was a good way to start the season."
