Best 18-Month CD Rates in South Dakota, SD

You are viewing rates from banks across South Dakota

Below are eighteen-month Certificates of Deposit (CD) rates from banks in South Dakota . Eighteen Month CDs offer a bit more yield than 1-year CDs but require a longer time-commitment. Like any CD, you should consider the trade-off between the difference in yield and the required time commitment. If an 18 month CD pays significantly above the yield of a 12-month CD, it may be worth opening.

18 Month CDs - Branch Banks 2025

Banks offer a range of Certificates of Deposit (CD) with 18 month CDs being a popular term. An eighteen month CD obligates the holder to keep their money in the bank for eighteen months in return for a fixed rate of interest during that time period. All eighteen month bank CDs shown on BestCashCow are FDIC insured.

Eighteen month CDs can be opened in almost any bank branch as the are a mainstay of bank deposit products.

The advantages of an eighteen month CD are:

A slightly higher rate than 12 month CDs in return for leaving the money in the bank longer.
A fixed rate during the 18 month period.
FDIC insurance.
Convenience of opening and managing the CD at a local branch.

The disadvantages of an eighteen month branch CDs are:

Rates are generally lower than on the top online savings and CD accounts.
Money is tied up for 18 months. Removing it early results in significant penalties.
Opening in a branch requires a personal visit.
