How to plan for retirement in your 70s and beyond
Clients who are in their 70s and unable to finish their retirement plan are advised to continue working while they can and invest or save their Social Security benefits, according to the personal finance website Motley Fool.

While they are required to take distributions from their retirement accounts, they can still save and invest this money outside these accounts. --Motley Fool

People who earn a living independently by offering contractual and on-call services need to prepare for retirement even if they don't get the perks as regular employees do, according to Morningstar. Those who opt to take part in the "gig economy" are advised to set up a fund for short-term financial hardship before building their nest egg.

It's easy to get the odds your retirement will be ruined wrong
Retirement planning may be better off discarding the use of "probabilities of ruin" in determining how long a nest egg will last, according to experts. "The only way to be able to forecast these things is based on prior data or history. There simply isn’t enough history to be able to forecast these things with confidence in the context of financial markets," says an expert.
