What Superior Savings Bank pays on deposits
FDIC call report data
An advertised rate tells you what a new savings account earns today. It cannot tell you how the bank has priced the savings and money market deposits it already holds, over time. This section shows that. The figure is computed from the interest expense and deposit balances that every bank files with the FDIC in the same form. That is what makes it comparable across banks and across quarters.
The two figures answer different questions, so they sit side by side and are not combined. The 3.56% needs a balance of at least $100,000. Below that, the account advertises 1.75%.
In Q2 2026, Superior Savings Bank paid a higher average rate on savings and money market deposits than 83% of banks that reported a figure (FDIC call report). The all-bank median was 1.45%.

How to read these figures
What the average covers. It is an average across the whole bank, taken from its own quarterly FDIC call report. It covers savings accounts and money market deposit accounts, personal and business, at every balance tier. It also covers accounts that were opened years ago and keep the rate of those years. The FDIC line does not separate consumer accounts.
The second figure. The scale row also shows the average across all interest-bearing deposits: savings, interest checking, money market accounts, CDs, personal and business. That figure covers the whole deposit book. The two are shown separately and are not combined.
What the advertised rate covers. It is the rate that this bank advertises now for a new savings account. Banksparency records it from the bank's website on the date shown beside it.
Why the two differ. They measure different things, so this page shows them side by side and keeps them apart. An advertised rate applies to one account, opened now, at today's price. The average also includes older savings balances at the rates of earlier years, money market balances that were priced in a different rate environment, and business accounts. An average below an advertised rate is the usual result of that arithmetic. On its own it is not evidence about the account that you would open.
What the average is useful for. The bank files the data itself, under reporting instructions that are the same for every filer, and the same computation runs for every bank on this site. That makes it comparable in a way that an advertisement is not. Two things on this page read it: the percentile, which shows where the quarter sits among all filers, and the chart, which shows the direction the figure has moved across quarters.
What the average cannot tell you. It cannot tell you the rate that you would earn. No single customer earns the average. For your rate, read the advertised rate above and the rate tables on this page, each with the date it was observed.
What to do next. Use the advertised rate to work out what a new account earns. Use the chart to see how the quarterly average has moved against the all-bank median. Then compare the advertised rate against the current rates on the savings-rate tables before you open an account.
Definitions: Call Report · Rate Paid on Deposits · Interest-Bearing Deposits · Front Book and Back Book · Deposit Rate Percentile
Average annualized rates paid on savings and money market deposits, and on all interest-bearing deposits, quarterly. The FDIC line for savings includes money market deposit accounts and business savings deposits and does not separate consumer accounts. Source: FDIC call report data, as reported; it may be amended. The percentile compares all FDIC filers, count-weighted. A missing quarter is suppressed, never interpolated. The percentile counts the banks that paid strictly less on savings and money market deposits, one vote per bank, among the banks that reported a figure for the quarter.
