Mutuals Matter

We’re Idaho’s Only Mutual Bank, Here’s Why That Matters

As a mutual bank, we’re owned by our depositors —not shareholders or investors. That means our customers and communities always come first. There are no outside pressures or competing agendas. Instead, we reinvest back into the operations of First Federal, the products and services offered, and the locations we serve. This approach – the First Fed Difference - helps improve the lives of our customers and strengthens our communities. Here, customers truly matter because it is their bank.

First Federal is also proud to be deeply rooted in our communities, supporting Idaho through meaningful partnerships with local schools, colleges, nonprofits, small businesses, and countless community organizations. As the State’s only mutual bank, our commitment isn’t just financial—it’s personal. We invest in people, drive growth, and show up when it matters most.  

Founded in 1915 in Twin Falls, Idaho as a building and loan association – established to help solve a housing shortage in the Magic Valley – First Fed continues its storied legacy of serving the needs of the community and those that call it home. From our board of directors to our entire banking team, we are driven, dedicated, and engaged in our mission to enhance the financial well-being of customers.

Because First Federal is a mutual bank, we are able to offer a wide array of competitive products and services, allowing us to assist customers in every stage in life. From opening their first savings account, buying a home, starting a business, or planning for retirement, First Fed bankers guide customers every step of the way. For us it is not just completing a transaction, it’s about helping each person reach their financial dreams.

At First Federal, we don’t just believe in Idaho, we are Idaho. We are a bank built on trust, shaped by community, and driven by a purpose that has remained unchanged for over a century. Experience the First Fed Difference to see why we are Idaho’s Community Bank of Choice.

We may change the interest rate on your account at any time. There are no maximum or minimum interest rate limits for this account. Interest will be compounded monthly and will be credited to the account monthly. If you close your account before interest is credited, you will receive the accrued interest. You must deposit $1,000.00 to open this account. A service fee of $10.00 will be imposed every month if the average daily balance for the month falls below $1,000.00. You must maintain a minimum average daily balance of $5.00 to obtain the disclosed annual percentage yield. A dormant account fee of $5.00 per month will be charged after 12 months of inactivity. Interest earnings credited to the account, if any, are not considered account activity.

We use the average daily balance method to calculate interest on your account. This method applies a periodic rate to the average daily balance in the account for the period. The average daily balance is calculated by adding the principal in the account for each day of the period and dividing that figure by the number of days in the period. The average daily balance that we use when calculating interest is the collected balance. That means we only include those funds for which we have actually received payment when we determine the average daily balance on which interest is paid. Interest begins to accrue no later than the business day we receive credit for the deposit of noncash items (for example, checks). Withdrawals from your MMDA are limited to six (6) per statement cycle. A fee of $10.00 will be charged for each transaction in excess of limit. Please refer to the separate Fee Schedule provided to you with this disclosure for information about fees and charges associated with this account.
