The Best Gift for College Graduates Is Help With Retirement

New graduates face fierce financial headwinds of soaring rent, ballooning student debt and inflation. The oft-repeated message to the young to “save early and often” may feel near-impossible. Still, it's worth highlighting the benefit of doing so for those who can somehow squirrel some money away.

One of the most compelling reasons is regret. By others, that is. Almost 70% of Gen Zers and 77% of millennials say they wish they had invested earlier, according to a survey by Magnify Money.

The median retirement account balance for all earners is about $15,000. Since 90% of earners of all ages are not on track to retire comfortably, the tidal wave of national regret is no surprise. One appreciates too late that the most powerful law in the economic universe is the power of compound interest.

Consider this: At age 35, you should have twice whatever your annual salary is tucked away in retirement savings, four times at age 45, seven times at age 55 and 11 times at age 67, according to consulting group Aon. That means a 45-year-old earning $100,000 a year should have $400,000, while a 67-year-old at the same income needs $1.1 million of retirement savings to use in conjunction with Social Security to maintain the same standard of living until death.

Simple math tells us starting to save at an early age requires the least sacrifice. Starting early means two-thirds of that $1.1 million comes from investment earnings, not your own hide. The sooner you save the the more the financial markets do the heavy lifting.

To accumulate the necessary retirement account balance at age 67, an average-earning 25-year-old needs to save 16% of her pay every year. At age 35, she'll have to save 25%; start at 50 and she'll need to save half of her take-home pay.
