Credit Union Membership Growth Benchmarks 2026: NCUA Call Report Analysis

Key Findings: RC Strategies Analysis of NCUA Q4 2025 Call Report Data

• Direct answer: Approximately 45% of federally insured credit unions grew membership in the year ending Q4 2025; 55% reported fewer members than a year earlier. The median membership growth rate was -0.5%, meaning the typical credit union lost members even as total industry membership climbed.
• Key insight: Credit unions above $1 billion in assets grew membership by 4.5% to 5.9%, while those under $50 million shrank by 7.1%. RC Strategies measures this 12-to-13 percentage point spread as the Credit Union Growth Gap Index.
• RC Strategies perspective: Aggregate industry membership figures mask a structural divide in which asset size has become the single strongest predictor of whether a credit union will grow or shrink. The $500 million asset threshold separates growth from contraction across every NCUA reporting period we analyzed.
• Actionable takeaway: Credit union leaders should benchmark against their asset-tier median, not the industry headline. If your institution is below the $500M threshold and posting negative membership growth, the compounding effects of declining revenue, reduced investment capacity, and accelerating consolidation make 2026 the year to build a systematic member acquisition engine.

Total credit union membership is growing. Most credit unions are not. RC Strategies' analysis of NCUA Q4 2025 Call Report data found that industry membership reached 144.7 million at year-end 2025 and climbed to 145.8 million by Q1 2026, a gain of 2.5 million members year-over-year. That is the headline most trade outlets ran. The more useful number for strategic planning is the median: -0.5% growth, meaning the typical federally insured credit union ended the year with fewer members than it started with.

The 55%/45% split flips the conventional narrative. More than half of all federally insured credit unions contracted. The aggregate grew because growth at the top of the asset scale, concentrated in the largest institutions, outweighed contraction everywhere else. This is not a new trend. It is an acceleration of a structural divide that has been widening for years.

The Credit Union Growth Paradox: Aggregate Growth, Individual Decline

The NCUA's Q4 2025 Quarterly Data Summary reported that credit union membership grew by 2.4 million during the year and total assets increased 5.4% to $2.43 trillion. Taken at face value, these are healthy numbers. They are also misleading if used as the baseline for any individual institution's strategic plan.

Why the Median Matters More Than the Mean

Aggregate growth figures reflect the sum of all member additions divided by total prior-year membership. A single $50 billion credit union adding 200,000 members can offset membership losses at hundreds of smaller institutions. The median, by contrast, represents the midpoint of individual credit union growth rates. It tells you what the typical institution actually experienced.

At -0.5%, the median says that if you lined up all 4,287 federally insured credit unions by their membership growth rate, the one in the middle lost members. The NCUA's own Q4 2025 Quarterly Map Review confirmed the scope: about 55 percent of federally insured credit unions had fewer members at the end of Q4 2025 than a year earlier.

An Acceleration, Not an Anomaly

By Q1 2026, the picture had not improved for most institutions. Federally insured credit unions added 2.5 million members over the year to reach 145.8 million across 4,250 institutions. But the concentration of that growth continued to intensify. The paradox is the story: the industry is growing while the majority of its institutions are shrinking.

Where that growth is concentrated, and where the losses are deepest, follows a clear pattern. Asset size predicts membership trajectory more reliably than geography, demographics, or product mix. Here is what the data shows by tier.

Fewer Credit Unions, Bigger Mergers: The Consolidation Accelerant

The charter count tells its own story. RC Strategies' analysis of NCUA quarterly data found a net loss of 168 charters in a single year: from 4,455 federally insured credit unions at Q4 2024, to 4,287 at Q4 2025, to 4,250 at Q1 2026. That is a 3.8% decline in one year.

The Scale of Mergers Is Shifting

The more significant change is not how many credit unions are merging. It is how large the merged institutions have become.

The $263.4 million average merge-in size in 2025 is the most important number in the consolidation story. It means the assumption that "this only happens to tiny credit unions" no longer holds. Institutions with $100M to $500M in assets, the same tier posting -3.7% membership growth, are now squarely in the consolidation risk band.

Half the Small Charters Are Gone

Compared to 10 years ago, there are approximately half as many charters with assets less than $50 million. The consolidation trend is accelerating even as the total number of individual mergers has declined since 2018. Fewer deals, but much larger ones.

Nearly two-thirds of credit union executives now identify new member growth, operational efficiency, and deposit gathering as top concerns, according to Cornerstone Advisors research. That anxiety is well-founded. For a deeper analysis of the systemic forces at work, RC Strategies has published a companion report on why more than half of credit unions are losing members.

The consolidation pressure is partly financial, partly competitive. But there is a third factor that does not show up in the asset-tier tables: the industry's aging membership base and its struggle to reach younger Americans.

The Membership Pipeline: Why the Growth Gap Compounds Over Time

The demographic composition of credit union membership adds a compounding dimension to the growth gap. The average credit union member is in their mid-50s, and less than 20% of Americans under the age of 40 use a credit union, according to Filene Research Institute data.

Gen Z and Millennial Penetration Is Critically Low

Apiture/Harris Poll research found that 79% of Gen Z and 69% of millennials choose large banks as their primary financial institution. Credit unions have captured only 11% of Gen Z and 15% of millennials as members. Millennial membership as a share of total credit union members has fallen from 31% in 2023 to 22% in 2025, a 9-point drop in two years.

These figures represent a pipeline problem, not a branding problem. Larger credit unions have the marketing budget and digital infrastructure to reach and convert younger members. Smaller ones often do not. The gap compounds: shrinking membership produces shrinking revenue, which produces less capacity to invest, which drives further shrinkage.

Executive Awareness Is Rising, but Action Is Lagging

Cornerstone Advisors' "Next-Level Growth" research found that 62% of credit union executives ranked new member growth among their top three concerns in 2025, up from 41% in 2022. That is a 51% increase in executive anxiety over three years. Recognition is not the problem. Execution velocity is.

Credit unions that are successfully acquiring younger members are doing so through integrated systems, not isolated campaigns. RC Strategies has documented the specific tactics that are working for credit unions acquiring younger members in a separate analysis.

The data is clear about the problem. The more useful question for a credit union leader is: what distinguishes the 45% that grew? And what can the 55% do about it?

What the Benchmarks Tell Credit Union Leaders and What to Do Next

The Credit Union Growth Gap Index is structural and widening, but it is not deterministic. The pattern among growth performers is consistent: they treat membership acquisition as a full-funnel system with integrated strategy, digital infrastructure, data-driven media, and a seamless member experience. Not a campaign. A system.

What a Growth System Produces

RC Strategies' credit union go-to-market work provides a concrete benchmark. In one engagement with a Florida-based credit union, the integrated system produced measurable outcomes across the entire funnel:

• Membership growth went from stagnant 1% to roughly 5%
• Online account completion rates jumped from 38% to 56%
• Auto loan originations surged 25% in a single quarter

These results did not come from a single channel or a rebranding exercise. They came from building the operating system for growth: integrated digital marketing for credit unions that connects strategy to media to experience to conversion.

The Window Is Narrowing

For credit unions currently below the $500M breakpoint and posting negative membership growth, the window to build that system independently is narrowing. Consolidation pressure and the demographic pipeline problem do not pause while planning cycles run. The 12-to-13 percentage point Growth Gap Index reflects resource allocation and system maturity, not fixed market position. It can be closed, but not with incremental adjustments.

Frequently Asked Questions: Credit Union Membership Growth 2026

What percentage of credit unions grew membership in 2025?

RC Strategies' analysis of NCUA Q4 2025 Call Report data found that approximately 45% of federally insured credit unions grew membership in the year ending December 2025. The remaining 55% reported fewer members than a year earlier, making membership decline the more common outcome for individual institutions despite positive industry-wide totals.

What is the average credit union membership growth rate in 2025?

The median membership growth rate across all federally insured credit unions was -0.5% for the year ending Q4 2025, according to RC Strategies' analysis of NCUA data. While aggregate industry membership grew by approximately 1.7% (2.4 million members), the median figure more accurately reflects the typical institution's experience because it is not skewed by outsized growth at the largest credit unions.

How many credit unions are there in 2026?

As of Q1 2026, there were 4,250 federally insured credit unions in the United States, according to NCUA data analyzed by RC Strategies. That figure is down from 4,287 at Q4 2025 and 4,455 at Q4 2024, representing a net loss of 168 charters (3.8%) in a single year.

Which states have the highest credit union membership growth?

RC Strategies' analysis of NCUA Q1 2026 Map Review data found that Vermont (+3.4%) and Alaska (+2.0%) posted the highest median credit union membership growth rates. Both states had smaller total populations and more concentrated credit union market share than the national average, creating a competitive environment that differs from high-density metro markets.

Why are credit unions losing members?

The primary driver of credit union membership decline is a structural growth gap tied to asset size, not a single operational factor. RC Strategies' analysis found that credit unions under $500 million in assets are contracting across all sub-tiers, while those above $500 million are growing. This divide is compounded by an aging membership base (average member age in the mid-50s), low penetration among Gen Z (11%) and millennials (15%), and a reverse flywheel in which shrinking membership reduces the revenue available to invest in the digital infrastructure and marketing systems needed to attract new members.

What is the Credit Union Growth Gap Index?

The Credit Union Growth Gap Index is a metric defined by RC Strategies that measures the spread in annual membership growth rates between the largest and smallest credit union asset tiers, using NCUA Quarterly Data Summary figures. For the year ending Q3 2025, the index was approximately 12 to 13 percentage points: the $1B+ tier grew at +4.5% while the sub-$50M tier contracted at -7.1%. The index quantifies the structural divide in credit union membership growth and serves as a benchmark for tracking whether the gap is widening or narrowing over time.
