Why March Is One of the Riskiest Months for Retention (And What to Do About It)

A look at post-bonus employee turnover trends across marketing, finance, and HR – and what the data actually tells us.

If you’ve ever had a strong employee put in their notice in March or April, you might have chalked it up to bad timing. But there’s a good chance it wasn’t random.

For a lot of employees, bonus season works like a quiet countdown clock. They stay through the payout, and then they move. A 2025 survey of 2,000 U.S. workers found that 48% of bonus-expecting employees planned to quit after receiving it – and 68% said they had stayed at a job longer than they wanted to specifically to collect a bonus before leaving.

That’s not a small number. And it means the 4–8 weeks after payouts clear are worth paying attention to, especially if you’re managing teams in marketing, finance, or HR – three functions where this pattern shows up most clearly.

Here’s what the data tells us by function, and a few practical ways to think about your response.

Marketing: Higher Baseline Turnover and a Competitive Recruiting Environment

Marketing doesn’t have the dramatic annual bonus cliffs you see in investment banking, but it does have consistently high baseline turnover and a talent pool that gets recruited year-round.

Annual voluntary turnover in marketing runs in the mid-teens to low-20s percent range, similar to other revenue-adjacent functions. For context, sales roles – which often sit alongside marketing in go-to-market teams – run about 35% annual turnover, nearly three times the all-industry average. That’s the environment marketing talent is operating in and comparing itself to.

A meaningful share of that annual churn tends to concentrate in the weeks right after bonus payouts. The roles most likely to be affected: Performance Marketing Managers, Marketing Ops leads, Demand Gen Directors, and senior Brand Managers. These roles are in high demand, and the people in them tend to know what the market is paying.

One piece of context worth keeping in mind: Payscale’s 2026 Compensation Best Practices Report found that 31% of companies identified underpaying as their primary reason for losing talent. With leaner teams, a single marketing exit can have an outsized impact – institutional knowledge, campaign history, and vendor relationships often walk out the door with the person.

Finance: A More Predictable Pattern, Especially in Certain Sub-Functions

Finance has the most well-documented post-bonus exit pattern of the three functions covered here, and in some areas it’s highly concentrated by timing.

In public accounting, April through June departures run 40–60% above baseline, largely tied to professionals leaving after busy-season bonuses clear. In banking and capital markets, Wall Street bonuses hit a record $47.5 billion in 2024 – and large payouts have historically corresponded with a wave of exits in the weeks that follow. Reuters reported that bonuses were expected to be the highest in four years, which means the runway for potential departures this cycle is longer than usual.

For corporate finance roles outside banking, the steady-state picture is calmer – monthly turnover in finance and insurance runs around 1.6%, below many other sectors. But that average doesn’t reflect the exposure at the senior and specialist level. FP&A Directors, Controllers, and Senior Financial Analysts are in short supply relative to demand, and they tend to have a clear sense of what the market offers.

The roles worth keeping an eye on right now: Senior Financial Analysts (especially FP&A-focused), Controllers, Finance Directors, and anyone who was heavily involved in budget modeling this quarter. These are often the people who built the financial case for everyone else’s investments – and who are now doing their own math.

HR: The People Processing Everyone Else’s Raises

This one is worth sitting with for a moment.

HR teams spend the first couple months of every year administering review cycles, processing merit increases, and coaching managers through pay conversations. They are, in many ways, the architects of everyone else’s retention planning – while their own compensation often gets reviewed last, if at all.

The turnover data reflects this. According to the Talent Strategy Group’s 2025 CHRO Trends Report, Fortune 200 CHRO and CPO turnover hit 15.5% in 2024 – a 36% increase year over year. In the Fortune 151–200 band, it reached 24%. Those positions collectively oversaw more than 2 million employees and $1.5 trillion in annual revenue, so the ripple effects of HR leadership turnover are significant.

Across HR functions more broadly, annual voluntary turnover runs around 15% – higher than finance and most corporate functions. Layering the post-bonus timing on top of that baseline suggests a real concentration of risk in March and April for teams that just wrapped annual review cycles.

The roles most exposed: Senior HR Business Partners, Compensation and Benefits specialists, and Talent Acquisition leaders. These are also among the hardest positions to replace quickly – and the ones where institutional knowledge is most embedded and most invisible until it’s gone.

One additional data point from the same CHRO report: internal CHRO succession dropped from 73% in 2023 to 53% in 2024, a 27% decline in a single year. Companies are increasingly going external for HR leadership, which often signals that the internal pipeline either wasn’t developed or didn’t stay long enough to step into the role.

The Underlying Issue Across All Three Functions

The common thread running through all of this isn’t really about bonuses – it’s about employees doing a compensation gut-check at a moment when they have the time and financial cushion to act on it.

Payscale’s research found that 68% of employees who are actually paid fairly still believe they’re underpaid. That perception gap is a retention risk on its own, separate from whether someone is actually below market. When employees don’t have visibility into how their pay was determined, or haven’t had a direct conversation about it in a while, the post-bonus window is when they’re most likely to go look.

The practical response isn’t complicated, but the timing matters. Benchmarking after someone puts in notice is rarely useful. Having that data – and that conversation – before the exit window opens is where it actually helps.

A Few Things Worth Doing Before the End of March

If you manage a team in any of these functions, here are a few practical starting points:

  • Identify your two or three highest-risk roles – the ones where a departure would be hardest to absorb and hardest to backfill quickly
  • Do a comp check on those roles specifically before you’re reacting to a resignation
  • Have a proactive conversation with the people in those seats – not to interrogate them, but to be direct about what you see for them and what’s coming
  • Know what you’d be willing to offer to keep them before you’re making that call under pressure

None of this requires a major retention initiative. It mostly just requires treating the post-bonus window as a predictable moment worth planning for, rather than being surprised by it every spring.
