ALBANY — Senator Joseph L. Bruno, who led the State Senate for 14 years, has offered many reasons why he is leaving the Senate by the end of the week after a public career of four decades.

There is another factor to consider, though.

Mr. Bruno, a Republican, is likely to get a significant raise from the state by retiring.

He is paid the base legislative salary of $79,500, but his pension, which is a percentage of the average of his three highest-salary years, will be $90,000 to $100,000, because until June he received an extra $41,000 a year for being majority leader, according to the state comptroller’s office. He would be giving up somewhere in the neighborhood of $1,300 a month, before taxes, by remaining in office.

He already received, in a lump sum earlier this year, most of the $41,000 for his role as majority leader and temporary president of the Senate.

Because he stepped down from his leadership role late last month, the balance of that bonus is likely to go to his successor as Senate majority leader, Dean G. Skelos.

John McArdle, a spokesman for Mr. Bruno, said the pension issue “had no bearing on his decision to leave.”

Mr. Bruno can defer some of his pension payments to a beneficiary who could receive payments in the future, but Mr. McArdle said, “I don’t think he’s even looked at that.”

Not that Mr. Bruno will be relying solely on his pension. He has made it clear in recent days that he has other plans.

“I’m not the kind of guy who’s going to go off and retire and just play with horses and golf,” he said at a public event on Tuesday. He has said he would like to go to work for one of the many technology companies in and around his Albany-area district, many of which have received state aid at his discretion.

“It can get depressing if I hang around, for Pete’s sake,” said Mr. Bruno, who has rarely missed a chance in his long career to land a joke. “I push the buttons, and nobody’s answering. That’s not a good thing.”

Mr. Bruno was eligible to be credited with 41.73 years of service, according to the comptroller’s office. He also helped enact legislation in 2000 that allows a relatively small number of the longest-serving retirees to receive extra credit for, in his case, an additional two years of service.

The size of state pension and benefit packages has long been a point of contention for fiscal conservatives. Public benefits in New York seem to be increasingly moving in opposition to private-sector benefits; the former seem perennially enriched by lawmakers eager for union support, and the latter seem starved by globalization and economic turmoil, among other factors.

On Tuesday, for example, General Motors announced that it was eliminating health care benefits for all of its salaried retirees. New York State, however, has the kind of benefits that retirees of the Big Three automakers in Detroit used to take for granted in a different era.

Retired lawmakers typically pay premiums just under $50 a month for health coverage, according to the State Department of Civil Service, and $5 co-payments for generic drugs.

“There needs to be a larger examination of overall compensation of public-sector employees,” said Elizabeth Lynam, deputy research director for the Citizens Budget Commission. Lawmakers, she added, “have been sweetening it and putting on bells and whistles, rather than stepping back and taking a look at the larger picture.”

Mr. Bruno can also draw on his $1.7 million campaign account, a source that current and former lawmakers frequently use to pay for meals, hotels and a variety of expenses, so long as they are at least loosely tied to political purposes. In Mr. Bruno’s case, it has also served as his de facto legal defense fund.

Mr. Bruno said this week, with tongue in cheek, that he would miss critiques by the press.

“It’s a very emotional time. When people abuse me, I’m kind of used to that, and so that toughens me up,” he said. “If you really want to make me cry,” he added, “start saying nice things.”
