The average associate attrition rate at US law firms is 19%, according to the NALP Foundation's most recent Update on Associate Attrition (calendar year 2025, released April 2026). But the headline rate understates the real story: 83% of associates who left in 2025 did so within five years of being hired — an all-time high — and attrition runs hottest at the smallest firms, reaching 24%.
The NALP Foundation's CY2025 Update, drawn from 141 US and Canadian firms, reports:
- Overall associate attrition: 19% — down slightly from 20% in 2024.
- 83% of 2025 departures occurred within five years of hire — a record high, up from 80% in 2024.
- Firms with 100 or fewer attorneys: 24% attrition — the highest of any size band.
- Larger firms: 16–18%, depending on size.
- In a shift from prior years, lateral hires exceeded entry-level hires in 2025.
For historical context, NALP's overall rate was 26% at the 2021 peak, fell to 18% in 2023, ticked up to 20% in 2024, and now sits at 19%. The overall rate has stabilized — but the timing of departures has moved decisively earlier, which is the metric that should concern firm leadership most.
Why the "Within Five Years" Number Matters More Than the Headline Rate
A 19% overall rate can read as manageable. The 83%-within-five-years figure cannot. It means the overwhelming majority of attrition is concentrated in exactly the cohort firms invest most heavily to recruit, onboard, and train — and lose before that investment pays back.
The financial weight of this is documented. BigHand's 2025 "Navigating the Million Dollar Problem", surveying 800+ senior law firm leaders, found firm-wide lawyer attrition at 27% (a broader measure than NALP's associate-only figure, spanning all seniority levels) and put the cost of replacing a third-year associate at over $1 million in lost billable revenue, recruitment, and training. The same report found associates leaving the legal profession entirely roughly doubled, from 9% in 2024 to about 16% in 2025 — meaning a growing share of departures aren't lateral moves the firm can backfill from the same talent pool.
Why the Two Headline Attrition Numbers Differ (19% vs 27%)
It's common to see both figures cited, so it's worth being precise:
Neither is wrong — they measure different populations. Use 19% for associate-specific discussions and 27% when describing attrition across the whole firm.
What Drives Early Associate Attrition
Across the NALP and BigHand data and broader industry research, the recurring drivers of years 1–4 departure are consistent: uneven work allocation, limited visibility into development and career path, insufficient or unclear feedback, and work-life and hybrid-work expectations that firms are slow to meet. Notably, compensation increases have not reversed the trend — pay has risen even as early attrition climbed, which points to structural and developmental causes rather than purely financial ones.
💡 Key Insight: The headline associate attrition rate (19%) has stabilized, but when associates leave has shifted to a record-early concentration — 83% within five years. Firms that track only the overall rate will miss the more actionable signal: the cohort they invest most in is leaving before that investment returns. Early-tenure feedback data — upward reviews, engagement surveys, exit surveys — is how firms detect the cause while the affected associates are still there to retain.

Frequently Asked Questions
What is the average associate attrition rate at US law firms?
The most recent figure is 19%, from the NALP Foundation's Update on Associate Attrition for calendar year 2025 (released April 2026, based on 141 US and Canadian firms). This is down slightly from 20% in 2024. However, the rate varies sharply by firm size: firms with 100 or fewer attorneys saw 24% attrition, while larger firms ranged from 16% to 18%.
What percentage of associates leave within five years?
83% of associates who departed in 2025 left within five years of being hired — an all-time high, up from 80% in 2024, per the NALP Foundation. This means the large majority of associate attrition is concentrated in the early-tenure cohort that firms invest most heavily to recruit and train.
How much does associate attrition cost a law firm?
BigHand's 2025 research estimates that replacing a third-year associate now costs over $1 million, accounting for lost billable revenue, recruitment, and training. Because most attrition occurs early — when firms have invested in onboarding and development but not yet recouped it — the financial exposure is concentrated in exactly the cohort leaving fastest.
Why is the law firm attrition rate sometimes reported as 27%?
The 27% figure comes from BigHand's 2025 report and measures firm-wide lawyer attrition across all seniority levels — associates through equity partners. The 19% figure from NALP measures associate attrition specifically. Both are current; they simply count different populations.
Is associate attrition getting better or worse?
The overall associate rate has stabilized — 26% at the 2021 peak, down to 18% in 2023, 20% in 2024, and 19% in 2025. But the timing of departures has worsened: the share leaving within five years hit a record 83% in 2025, and the share leaving the profession entirely roughly doubled year-over-year. So the rate is steady, but departures are happening earlier and are harder to backfill.
What can law firms do to reduce associate attrition?
Because most attrition is early and driven by development, feedback, and work-allocation issues rather than pay, the most effective interventions are structural: clearer development paths, more equitable work allocation, and honest feedback systems that surface problems early. Upward reviews, engagement surveys, and exit surveys let firms detect the specific drivers — and which supervising partners are associated with them — while there's still time to act.
The average US law firm associate attrition rate is 19% (NALP, CY2025) — but the number that should drive decisions is 83%: the record share of departures happening within five years of hire. Attrition has stabilized in aggregate while concentrating earlier and growing more expensive, with each lost third-year associate costing north of $1 million. Firms that monitor only the headline rate will keep missing the actionable signal. The ones reducing early attrition are measuring its drivers directly — through honest, early-tenure feedback — and acting before the associates they've invested in walk out the door.
