I am still w*rking and intend to ER at 55.
I have a non-cola DB pension... but if I ER, the amount I get is reduced based on the age at ER... plus I will have fewer years of time with the company than if I stuck it out till 62 or 65.... therefore it will only cover about 30% of our base income needs (expenses). However, I have planned for higher expense during ER so DW and I can travel therefore it is only about 15% of planned income.
DW had a generous cash contribution plan (of sorts) with Mega Corp. The investments have grown over the years.... Of course, the investments have suffered over the last year. If she purchased a joint life annuity the current asset value would cover about 75% of her final wages. Before this market setback, it would have purchased a joint annuity for 100% of her wages (She is not planning on doing this... but it provides some perspective)
We both have SS and Retirement Health Care. Of course, Retirement Health care is not guaranteed. The companies could take it away or jack up the premium. We plan to hold on to both plans (her company and mine) at least until medicare kicks in just in case one of the companies drops the plan.
We have other accounts... 401k, IRAs, and Taxable.
