Jones, who was originally contracted to the post until the culmination of the 2019 Rugby World Cup in Japan, will now remain at the RFU at the helm of English rugby until 2021.
If as planned he works above his successor for a year, Jones insists he "will have the ultimate say, it can't be more black or white than that", and has ruled out extending his stewardship any further.
Jones has often spoken of looking forward to his retirement trips to the West Indies but that enticing prospect has been postponed after what he said was an easy decision.
Jones has been given an additional two years as reward for his success in overseeing a run of 22 wins from 23 Tests, a sequence that features consecutive NatWest 6 Nations titles including a Grand Slam.
The 57-year-old has made it clear that anything other than winning the next global gathering will be regarded as a failure, although the RFU's chief executive, Steve Brown, refused to go into details about what outcome in Japan next year would activate the break clause. Jones is due to name his squad for the tournament on Thursday.
