For most credit unions, the honest answer to “are our lending products serving members well?” is: it’s hard to know without looking at the numbers. Two metrics make that question answerable. The first is credit union share of wallet – what percentage of a member’s loan products actually sit at your institution. The second is member benefit – how often a member would be better off with your product than the one they already have.
To find out, we analyzed data from over 9,000 applicants across 17+ credit unions representing 2.5 million members. The results point to a meaningful gap between what members need and what credit unions are currently capturing.
Where Member Debt Actually Lives
Nearly every member holds a credit card or auto loan. Roughly a third also carry a mortgage, student loan, or unsecured personal loan. The average member carries $139,000 in total debt across these categories, though the mix varies significantly by product and by geography – mortgage balances in California, for example, run far higher than in Kansas.
The interesting question isn’t how much debt members carry. It’s how much of that debt sits with their credit union.
The Share of Wallet Gap
When we measured actual capture rates across these portfolios, the numbers were lower than most lending leaders would expect:
- Auto loans, the strongest-performing category, still only captured 21.8% of member balances on average.
- Unsecured personal loans and credit cards showed even lower penetration.
In other words, even in the product category where credit unions compete best, members are placing roughly four out of every five dollars of auto debt somewhere else. That’s not a small leak – it’s the majority of the opportunity.
How Often Would Members Actually Be Better Off?
Low capture rates alone don’t tell you whether there’s an actionable opportunity. Members might be holding loans elsewhere because the rates are genuinely competitive, or because their credit profile doesn’t qualify for better terms. To test this, we used soft-pull credit data and decisioning models from a 100,000+ member credit union, focused on members with FICO scores above 640 – the typical credit union lending threshold.
The results were harder to dismiss:
Auto loans
- 45.5% of eligible members would save money by refinancing with a credit union.
- Even at a conservative bar of 3% APR savings or more, 22% of members would still benefit.
- Capturing this opportunity could roughly triple auto loan share of wallet.
Personal loans
- 32% of members with a FICO above 640 would save by switching their personal loan to the credit union.
- More than 10.7% would save over 9.75% APR – a substantial reduction.
- Capturing this segment could roughly quadruple personal loan share of wallet.
This is the part that matters most for lending leaders: these aren’t marginal savings for a handful of members. A meaningful share of the member base is currently paying more than they need to, at a competitor’s institution, for a product the credit union could already offer them at a better rate.
Why This Keeps Happening
Credit unions don’t lose this volume because members don’t trust them. They lose it because the opportunity is invisible until someone goes looking for it. Low credit scores, past delinquencies, and aggressive promotional rates (0% APR auto financing, for example) explain some of the gap. But they don’t explain all of it—and the soft-pull data shows exactly how much is left on the table once those factors are accounted for.
The strategic question isn’t “how do we win new members.” It’s narrower, and more solvable: why is the credit union losing loan volume it’s already positioned to win, and how does it get that volume back?
What This Means for Your Credit Union
Share of wallet and member benefit aren’t just interesting metrics – they’re a roadmap. If your credit union is capturing anywhere near the averages above, there’s a real, quantifiable opportunity sitting inside your existing membership, not in a new acquisition channel.
The credit unions that close this gap fastest are the ones that can surface refinance and consolidation opportunities to members proactively, before those members go looking for a better rate somewhere else.
