Locking your money into an 18-month certificate of deposit (CD) account can be daunting, as the account requires you to leave the funds frozen until it hits its maturity date. Withdraw it prematurely and you'll get hit with a penalty worth all or most of the interest earned to that point. But forgoing access can be difficult to do for small amounts and even harder for those with larger, five-figure sums such as $40,000.

Finding these rates, however, will require some shopping around online. But with online banks often offering the most competitive rates and terms and with online marketplaces making it easier than ever to comparison shop now, this can be done quickly and effectively.

While transferring $40,000 into an 18-month CD will require some extended sacrifice on behalf of savers, it's not the only CD term available nor is it the only one to consider now. Savers can secure competitive rates with 1-year CDs, too, and accounts with terms that mature under 12 months also have rates in the high 3% to low 4% range.
