What an online CD lineup like this one really offers

Marcus by Goldman Sachs is the consumer deposit brand of Goldman Sachs Bank USA, and its CD lineup is deliberately plain: one published rate for each term, a low minimum, no relationship requirement and no branch. That structure explains why online banks routinely post rates well above the national average — none of the property and staffing costs of a branch network fall on them, and some of that saving comes back to you as yield.

On the lineup as last checked, a $10,000 twelve-month CD at 4.00% earns $400. That same money at the 1.68% national average earns $168. The insurance is identical either way — FDIC to $250,000 per depositor, per bank, per ownership category — so the $232 difference is bought purely by choosing where the money sits.

What to verify before funding anything

Three checks, in order. Confirm the rate on the bank's own disclosure page, since the figures here are dated samples and online rates move without notice. Confirm FDIC membership for yourself using the FDIC's BankFind tool — it takes a minute and it is the only confirmation that counts. Then read the early-withdrawal penalty for your specific term: Marcus charges 90 days of simple interest on terms under a year and substantially more on longer ones — its disclosure has listed 270 days on one-to-five-year terms since a 2023 increase, while some third-party roundups still quote the older 180-day figure, which is exactly why the bank's own disclosure is the number to trust.

Finally, find the auto-renewal default and the grace period, usually 7–10 days. Renewal is where good rates quietly turn into bad ones: the certificate rolls into a new term at whatever is posted that day, which is rarely the promotional rate that attracted you. Diary the maturity date on the same day you fund the account.
