Compare the same 18-month term

Amount to deposit

Estimated interest before fees and tax assumes the quoted APY applies for the full term and all interest stays deposited. Taxes, fees and early withdrawals are excluded. Actual earnings follow provider terms.

Sorted by APY, highest first, before fees. These are reviewed accounts in our dataset, not every available CD. Check whether you qualify before opening an account.

How this comparison works

We compare only 18-month CDs with reviewed rates and terms. Rates and required terms must have current source evidence. We keep separate products separate, even at the same institution.

We sort by APY before fees, not by commission. This is not a personal recommendation or an exhaustive market ranking. Confirm availability and account requirements with each provider.

For 18 months, estimated interest = deposit × ((1 + APY ÷ 100)^(18 ÷ 12) − 1). Monthly fees are shown separately and not deducted.

This estimate assumes you leave all interest in the account. Early withdrawals can reduce earnings or principal. Renewal may use a different rate. If we cannot confirm early-closure or grace-period rules, we say so.
