Your retirement will be unique to you, but it often helps to have some rules of thumb as a guideline.
Over time it may make sense to revisit those rules. For example, experts
used to talk about retirement being based on a three-legged stool: a
pension, Social Security and personal savings. Such a scenario isn’t
applicable for most people these days, or at least not those working for
a private-sector company.
Fewer employees have pensions that guarantee lifetime monthly
payouts. There’s a lot of uncertainly about the financial stability of
Social Security. This means some of the advice that worked in years past
won’t apply to future retirees.
