According to the latest Business Owners Outlook from Wilmington Trust, the number of larger business owners who plan to retire sooner than expected shot up by 110% since August 2020, as confidence about the economy has taken a dive since the start of the COVID-19 pandemic. Moreover, the number of smaller business owners planning the same has doubled. Will those business owners have enough money put away to retire comfortably? Joel Anderson writes for GoBankingRates that a popular way to calculate retirement needs is to use Fidelity Investment's "10x income rule," which mandates putting aside 10 times your annual income in order to maintain a quality of life similar to the one you had while working. But Anderson notes that annual incomes are very different today than they were 10 or 20 years ago — or especially 30 years ago. Using U.S. Social Security Administration data on average annual wages, GoBankingRates has provided a look at the price tag for retirement from 1951 through 2019.
