UpTrajectory Review
Beth Pinsker asks whether a 5% 401(k) contribution rate can carry a worker through retirement, and the honest answer is that for most people it cannot. The conventional wisdom once held that saving 10% of income would suffice; financial planners now often recommend 15% or more, especially for workers who started saving late or who lack a pension. Pinsker's framing pushes readers to confront a gap between what feels comfortable today and what their future selves will actually need. The piece sits within a broader retirement-crisis narrative: Social Security replaces only about 40% of pre-retirement income for the average worker, leaving the rest to personal savings and employer plans.
For a small-business owner, this question carries extra weight. Owners often neglect their own retirement savings while pouring every dollar back into the business, and many assume the business itself will fund their exit. That assumption fails more often than it succeeds. If you employ staff, the contribution rate you set for yourself shapes the plan's testing requirements and affects how much your employees defer. A 5% default may keep participation numbers high, but it may also leave your workforce — and you — materially underprepared. Owners should treat their own 401(k) contribution as a fixed cost of doing business, not a discretionary bonus.
What Pinsker gets right is the emphasis on pushing limits now rather than hoping for catch-up later. The math of compounding rewards early sacrifice; every dollar deferred at 35 does roughly twice the work of a dollar deferred at 45. Where we push back is on any implication that 5% is a failure or that a single benchmark fits every household. A worker with a pension, no debt, and a paid-off home faces a different calculus than a freelancer with variable income and three children. The right rate depends on the gap between projected retirement income and projected retirement spending, not on an arbitrary national average.
The downstream effects of low contribution rates fall unevenly. Women, who live longer and earn less on average, feel the pinch hardest. So do workers of color, who are less likely to have access to an employer plan at all. Business owners who set low default rates may see higher participation but lower average balances, which creates reputational risk if employees retire into hardship. There is also a policy dimension: states increasingly mandate retirement plans for private employers, and federal proposals to expand access keep resurfacing. Employers who wait for a mandate may find themselves implementing a plan under deadline pressure rather than on their own terms.
Watch for updated IRS contribution limits each January, and review your plan's default deferral rate at least annually. If you own a business and have not raised your own rate in two years, raise it now — even one percentage point compounds meaningfully over a decade. If you are an employee, run a retirement calculator that accounts for your actual spending, not a rule of thumb. The question is not whether 5% is enough in the abstract. The question is whether your savings rate, your investment mix, and your timeline add up to the retirement you intend to have. For most readers, the answer will demand a higher number.

Takeaway: Audit your 401(k) deferral rate this month; if it sits at 5%, raise it by at least one percentage point and automate annual increases.
