The Number Nobody Calculates

Ask a business owner what turnover costs them and you'll get one of two answers: a shrug, or a number that's way too low.

That's because most people think of turnover cost as "the time it takes to hire a replacement." They're thinking about the job posting, the interviews, maybe a recruiter fee. That's real, but it's maybe 20% of the actual cost.

SHRM estimates turnover costs 6-9 months of the departing employee's annual salary. For a $50,000/year employee, that's $25,000-$37,500. For a $75,000 employee, it's $37,500-$56,000. For a manager or specialized role at $100,000+, you're looking at $50,000-$75,000 or more.

Multiply that by however many people you lose in a year. For a 50-person company with 20% annual turnover — which is average for many industries — that's 10 departures. At $50K average salary, the turnover tab is $250,000-$375,000 annually. That's not a line item on most P&Ls, but it's hitting the business whether they track it or not.

Where the Money Actually Goes

The 6-9 month estimate includes costs most owners never think about:

Institutional knowledge loss. The person who leaves takes relationships, context, workarounds, and tribal knowledge with them. The things that aren't written down — the reason a key client prefers email over phone, the quirk in the billing system that saves 20 minutes per invoice, the vendor contact who actually picks up. That knowledge walks out the door and nobody notices until something breaks.

Productivity gap. A new hire takes 3-6 months to reach full productivity, depending on the role. During that ramp-up, work is slower, mistakes are more frequent, and someone else is picking up the slack — which means their productivity drops too.

Team disruption. When someone leaves, the remaining team absorbs extra work. Morale takes a hit. Other employees start wondering: "Should I be looking too?" One departure can trigger a cascade if the underlying conditions aren't addressed.

Management time. Recruiting, interviewing, onboarding, training, and managing a new employee through their first 90 days consumes management attention that could be spent on revenue-generating activities.

Customer impact. In customer-facing roles, turnover means relationship handoffs. Some customers tolerate it. Others don't. The revenue risk is hard to quantify but very real.

The Hidden Cost: Financial Stress

Here's the part that almost never enters the turnover conversation.

PwC's 2023 Employee Financial Wellness Survey found that 57% of employees report financial stress as their top source of stress. Not workload. Not their manager. Money.

That financial stress costs employers approximately $1,900 per employee per year (John Hancock Financial Stress Survey, 2019) in lost productivity — through distracted work, increased absenteeism, and presenteeism (showing up but not fully functioning).

For a 50-person company, that's $95,000 in annual productivity loss from financial stress alone. Before anyone quits.

And financial stress is one of the top drivers of turnover. People don't always leave for a better title. Often they leave for any job that pays more — even marginally — because they're desperate to close a gap in their budget. If you could reduce that financial stress, you'd reduce the pressure that pushes people out the door.

Why This Matters for the Four Levers

Lower Turnover isn't about perks, pizza parties, or ping-pong tables. It's about addressing the root causes that make people leave — and the root causes that make them underperform while they're still there.

The 21-Day Challenge (Lesson 2.2) targets the three major drivers: health, wealth, and stress. The Employee Road Map (Lesson 2.3) sustains the momentum long-term. And the cross-lever connection to Operational Excellence (Lesson 2.4) gives employees the clarity and purpose that perks can't.

When you bring this to a business owner or a CPA, you're not talking about their retirement plan. You're not talking about HR strategy. You're talking about cash flow — money the business is losing right now that it doesn't have to lose.

That's a different conversation. And it's one that most retirement plan consultants never have.
