RTN share savings certificates are a safe and secure way to plan for retirement, save for a rainy day or perhaps for that special occasion in the future. We offer competitive rates with a minimum deposit of $1,000 on many certificates.

You can open high yielding certificates with terms from three months to 60 months (five years) for personal, non-retirement and/or IRA accounts. The longer the term of the certificate, the higher rate of dividends you’ll earn. Premium rates are paid on investments of $50,000 or more. Dividends are paid and compounded monthly.

Your RTN Share Savings Certificate funds are federally insured by the National Credit Union Administration (NCUA), an agency of the U.S. Government, up to $250,000 per account by ownership type. Account balances in excess of the amounts insured by NCUA are insured in full by the Massachusetts Share Insurance Corporation (MSIC).

To open your RTN Share Savings Certificate, visit an RTN branch.  Please make an appointment before your visit so we can serve you in a timely manner. Appointments may be made online or by calling a branch directly.

APY = Annual Percentage Yield.
Annual percentage yields (APY) are accurate as of December 16, 2022. $1,000 or $50,000 minimum balance required to open non-IRA, Roth or Traditional IRA certificate accounts and to earn dividends. Penalty imposed for early withdrawal of funds. APYs are subject to change at any time or may be withdrawn at any time without notice.

Please note: The 18-month certificate special will automatically renew at the end of the initial maturity as a 12-month certificate is subject to change or withdrawal at any time and is a limited-time promotional offer.

Fees and other conditions could reduce the earnings on the account. Dividends paid at month-end or certificate maturity. Contact Member Services at 781-736-9900 for current APYs.
