Most Reliable Banks (2026): Ranked by Customer Complaints
Every complaint filed with the Consumer Financial Protection Bureau becomes a public record. We use it to score 11 banks 0-100 on complaint volume relative to customer base — fewest complaints per 1,000 customers wins.
Ranking
How to read the score
Each bank's total CFPB complaints for the year are divided by an estimate of its customer base (derived from FDIC deposit data), then scaled 0-100 relative to every other bank we track. A score of 100 means the fewest complaints per 1,000 customers in the group; a score near 0 means the most. The badge (below average / average / above average) refers to complaint volume, not account safety.
Frequently asked questions
How is the complaint score calculated?
We take each bank's CFPB complaints per 1,000 customers (estimated from total deposits) for the latest full year and scale it 0-100 across the banks we track, where 100 means the fewest complaints per customer.
Does a low score mean a bank is unsafe?
No. All FDIC-insured banks protect deposits up to $250,000 regardless of complaint volume. The score measures customer-service friction, not solvency.
Why do big banks have more total complaints?
Total complaint counts scale with customer base. That's why we rank on complaints per 1,000 customers rather than raw totals — it's a fairer comparison between a regional bank and a national one.
How often is this ranking updated?
We refresh CFPB complaint data periodically as the Bureau publishes new records; the ranking reflects the latest full calendar year available.
