Do all AC new hires now get a defined contribution pension? How much is the contribution?
As mentioned all new hire pilots go on the DC plan.
Also, let's assume a guy just retired with DB pension. He worked for AC for 30 years, how much would he be earning annually (rough guess, let's say he retired off whatever equipment would be typical for a 30 year guy). Same question but for a guy who has been at AC for 20 years.
The maximum pension is just over $140,000 per year, the pension formula is based on years of service and a pilots best 60 consecutive months earnings. To reach the maximum pension a pilot requires 35 years of service (anything longer doesn't make a difference) and best 60 months average salary of over $230,000/year (anything greater doesn't make a difference).
At this time a pilot retiring with 30 years would likely have had the opportunity to have earned more than $230,000/Year, but not if they've decided to stay senior on the A320 or B767, or have been based in YVR, YUL or YWG, or perhaps been on disability. Although, I believe that 30 YOS would traditionally been enough to spend 5 years in the left seat of a B777/A340/A330 in YUL and YVR. FWIW, as the 767's are transferred to rouge and are replaced by 787's (heavier and faster) every wide body Captain position at mainline will provide a >$230,000 salary. So to answer your question, with 30 years and 5 years as a heavy Captain a retiree could expect a pension of about $127,000/year.
A pilot retiring with 20 years would be taking early retirement until they reach age 65 and would be subjected to a 6% penalty per year (from their 'new' retirement age of 65). Under the new pension rules a pilot requires at least 25 years of service by the time they turn 60 or their 'new' retirement age becomes 65. This sucks. Even if you have 24.9 years when you turn 60, your new retirement age is 65, and leaving early (if you can call 65 early?) subjects you to the penalty.
But this isn't what you've asked, so I'll try and stick to the subject at hand, a few examples because I'm actually curious to see what you come up with (hopefully you don't mind sharing?)
Best Average Earning = BAE
Years of service = YOS
25 YOS + $230,000 BAE = $106,000/year
25 YOS + $190,000 BAE = $87,000/year
20 YOS + $190,000 BAE = $52,000/year (at 60) or $76,000 at 65
Like I said, please share your results. You're comparisons to the DB plan, sadly, have now become irrelevant for those looking at joining AC
