The 1.44 million number looks scary, but remember -- that is after working many more year.
The pension calc usually looks like this
Years of service x 2% (or other number) x Annual salary (or average, etc).
So the key difference is that quitting today, you have fewer years of service, versus at age 65, when you will have 25+ more years. BUT -- That is because there will be 25+ more years of additional money contributions.
Instead, you could put the same (or less) additional money into your own self directed retirement plan over the next 25 years and easily replace it, if you like. Hopefully future employers that do not provide pensions give more $'s directly as compensation or you negotiate well.
So, you have not "lost out" on your pension, just moving it to a different format. The only times you "lose out" is when you collect a pension early, (lower payouts) and die early, or quitting before you are vested.
