A Vanguard report says that, of its customers enrolled in an automatic savings plan, 52 percent were in a program that only saved 3 percent, while another 28 percent had savings rates of 4–5 percent and only 20 percent had a savings rate of 6 percent or greater.

While Vanguard did not specify how many participants were saving 15 percent or more, the report says that “it was likely a fraction of 20 percent.”

And the average Vanguard customer saved just 6.2 percent of their income, with a median saving rate of 5 percent in 2016. Says the report, “Interestingly, these numbers were lower than any time since 2007, and Vanguard attributed the declines to an ‘increase in automatic enrollment.’”

In another report, Wells Fargo found that fewer than 40 percent of individuals automatically enrolled in its savings plan have a savings rate of 10 percent or more. In yet another report, Alight Solutions found in its 2017 survey of large employers that 37 percent of employers provided a default savings rate of 3 percent and another 30 percent have a rate of 6 percent.

That is so not enough.

It’s now recommended that people save at least 15 percent of their income, while some experts are going farther out on a limb to recommend 18 or even 20 percent.

But that isn’t happening, and indeed the auto-features could be encouraging people to take a similar hands-off attitude toward their 401(k)s that they once took with pension plans.

From a psychological standpoint, the article says, this is very dangerous: “Psychologists know only too well how easy it is for us to procrastinate, form overly rosy images about the future, buy impulsively, overspend, make bad spending decisions, and so on. What is more, emergencies today, whether they are medical or personal (divorce, job loss, etc.) can devastate personal finances. The upshot is that it is very difficult for many people to save adequately for their retirement.”

And what’s happening is that auto-features in a plan “may create the illusion that one’s retirement is taken care of, making people falsely complacent and unprepared,” as well as encouraging passivity in personal finances—and people are already reluctant enough to take the time and effort to learn about investments and understand exactly how investing and retirement plans work.

Automatic features are good for boosting enrollment and savings rates, but they’re not enough to prepare people for retirement or to get them actively engaged in their own financial futures. People tend to view them as a solution, instead of only part of a complete approach to retirement savings.
