Methodology & Sources

Sources

FDIC BankFind Suite API - institution roster, quarterly Call Report financials (latest quarter shown: June 30, 2026), and the failures list. FDIC data is a work of the U.S. government and is in the public domain.
FDIC Summary of Deposits (SOD) - deposits booked at every bank office as of June 30, 2026 (75,859 offices). Powers branch counts, footprints, and county/state deposit market-share pages.
NCUA Call Report quarterly files - Form 5300 data for every credit union that filed for June 30, 2026, plus NCUA branch data. NCUA data is likewise public domain.
U.S. Census Bureau gazetteer - county names for FIPS codes in the SOD file.

FDIC dollar amounts are reported in thousands and converted to dollars on this site.
Equity to assets is total equity capital divided by total assets - a simple leverage snapshot, not a regulatory capital ratio. Where the FDIC reports a Tier 1 leverage ratio, that is shown separately.
Uninsured deposits is the FDIC's estimate of deposits above the insurance limit, as a share of total deposits.
Noncurrent loans are loans 90+ days past due plus nonaccrual loans, as a share of total loans. Net charge-offs are loans charged off minus recoveries, annualized by the FDIC, as a share of loans.
Credit union net worth ratio is NCUA account 998 (net worth divided by total assets), the prompt-corrective-action capital measure.
Credit union delinquency is loans delinquent two months or more (accounts 021B+022B+023B) as a share of total loans.
Credit union return on assets is approximate: year-to-date net income (account 392) annualized against period-end assets.
Rankings apply minimum-size filters (shown on each page's source note) so tiny institutions do not dominate ratio rankings.

Branch deposits are booked at the office holding them, which is not always where the customer lives; online banks concentrate deposits at head offices.
Five-year trends use June snapshots only (June 2022 - June 2026).
Filings are as reported by institutions and are occasionally revised; this site reflects the files as published when the quarter's build ran.
The failures list counts FDIC failures only, excluding assistance transactions.

The site is rebuilt from source each quarter when new Call Report data is published.
