Embattled NHS boss Sir David Nicholson plans to retire next year, with a pension pot worth almost £1.9 million.
The NHS England chief executive officer, whose basic salary is £211,000, will step down from his role next March.
Campaigners called for the under-fire boss to be sacked after the publication of the Francis report into serious failings at Mid Staffordshire NHS Foundation Trust.
But instead of getting the axe, Sir David will walk away with a pension of at least £1,875,000 when he retires, according to NHS figures published in March last year.
Sir David, who has worked in the health service for 35 years, was in charge of the regional health authority responsible for Mid Staffordshire for a short period while patients were being mistreated.
Julie Bailey, from the campaign group Cure The NHS, said: "It is an obscene amount of money for failure. He will be able to enjoy the rest of his life, unlike us - we are left with memories of our loved ones suffering under his watch."
Ms Bailey, who set up the campaign group after her mother Bella died at Stafford Hospital in 2007, was still optimistic about Sir David's departure, adding: "This is the start of the cure for the NHS. We can start to look to the future now. He was part of the problem - not part of the solution. We now need a leader who will galvanise and inspire the front line, not bully them."
Despite numerous calls for Sir David to lose his position, he received backing from Prime Minister David Cameron and Health Secretary Jeremy Hunt in the wake of the inquiry. In March, he told MPs he was "absolutely determined" to stay in his job despite admitting failures over the Stafford Hospital scandal.
Asked for Mr Cameron's response to Sir David's retirement and assessment of his record, the Prime Minister's official spokesman said: "He agrees with the Secretary of State for Health."
Mr Cameron's view of Sir David was "unchanged" since the PM responded to the Francis report on Mid-Staffordshire, said the spokesman. He said he was not aware of ministers discussing the NHS chief's departure with Sir David in advance, adding: "It is his decision to retire."
