The number banks report and the number that matters are two different numbers

In a March 2026 ABA survey, seventy-two percent of community bank CEOs named core deposit growth as what keeps them up at night. Only cybersecurity ranked higher.

Yet, most digital deposit programs are still reporting on accounts opened.

Here’s the problem with that: an account opened is not a deposit. It becomes one when someone funds it, keeps it funded, and builds a relationship around it. Those are three separate events. Most programs are optimizing hard for the first one while the other two erode in the background.

According to a 2026 Cornerstone Advisors report, institutions lost an average of 3.36 digital applications for every successful account opened. Most of those applications disappeared before anyone at the bank even knew they existed.

Among accounts that did get opened? A meaningful share never funded.

Among those that funded? A significant portion were gone before 90 days.

If your deposit program is measuring accounts opened and calling it growth, you’re celebrating the start of the journey like it’s the destination.

The cost behind your acquisition numbers

Between 2020 and early 2024, the average community bank cost of funds jumped from 0.74% to 2.85%. That’s a 285% increase in four years. Half of all community banks turned to brokered deposits in 2024 to fill the gap, up from 39% the year before.

Brokered deposits are an expensive, rate-sensitive band-aid, and the opposite of the kind of funding that moves a balance sheet in the right direction.

The cost problem doesn’t stop at funding. When you add up what deposit growth actually requires: the manual hours in fraud review, the staff time spent on exception handling, the bolt-on compliance tools patched into a digital flow that isn’t designed to support them, the true price of each acquired account becomes a different number than the one we see on the dashboard. In many cases, an unsustainable one.

The better news: community banks grew deposits 5% in 2025, outpacing the broader industry. The caveat, according to a Kansas City Fed bulletin published last week, the core deposit ratio at community banks sits near 15-year lows, still below the long-term median of 89.6%. Volume is coming back, while mix and quality remain a problem.

What the funnel looks like when it actually works

Community banks running purpose-built infrastructure have seen average funded account balances reach $44,000 or more, with 90%+ monthly retention. The difference comes down to what happens between the application and the relationship.

Friction is the first leak. Banks that take more than five minutes to open an account digitally see abandonment rates exceed 50%. Eighty percent of banks are above that threshold. These aren’t casual browsers. These are people who came with intent but left because the experience made it too hard to stay.

Compliance built in, not bolted on. When fraud and compliance controls create friction at the wrong point in the onboarding flow, abandonment goes up and trust goes down. When they’re embedded intelligently, they protect the bank without costing the relationship.

Funding confirmation isn’t optional. If your onboarding flow makes initial funding awkward or easy to skip, you’re selecting for customers who won’t stick around.

Part of what makes this hard is structural. Much of the digital account opening technology in the market wasn’t designed with community bank workflows in mind; the compliance structure, the staffing model, or the regulatory environment.

The result is predictable: staff work around the system, key steps migrate to email and spreadsheets, and the “digital solution” effectively creates more manual load than it removes.

The banks improving their deposit mix have stopped optimizing for the application. They’re optimizing for what happens after.

The metrics worth tracking

If accounts opened is still your primary dashboard metric, here’s what to add:

Funded accounts per month: how many accounts that opened received an initial deposit. This is your first filter. Everything downstream depends on it.

90-day retention rate: The best-performing digital deposit programs are seeing 90%+ on this metric. The industry average for community banks is 83.1%. That gap is not small.

Cost per acquired account: total acquisition and onboarding cost divided by funded, retained accounts, not accounts opened. The denominator matters.

Average balance per funded account: $44K is a useful benchmark for what’s possible on a well-optimized digital deposit program. If your number is significantly lower, the deposit mix question is worth a closer look.

The opportunity right now

The difference between a bank that opened 3,000 accounts last quarter and a bank that funded 2,700 of them and still has 2,400 at 90 days is infrastructure.

Deposit growth that moves the balance sheet requires the full journey: who you attract, how cleanly you onboard, how safely you fund, how well you retain. When compliance, fraud controls, and customer intelligence are embedded directly into that journey, digital stops being a cost center and starts being the growth engine for the kind of deposits your board and your lending strategy need.
