Why this CD is so much lower than online competitors

Prosperity's branch-heavy model in smaller Texas markets carries typical regional overhead.

The branch-overhead math

A megabank branch costs roughly $1–2M per year to operate (real estate, staffing, security, utilities, IT, compliance). Multiply across thousands of branches and the bank’s effective cost of deposits is 2–3% before paying you a dime. An online bank with zero branches can pass nearly that entire spread back to depositors as APY. That’s why Marcus, Ally, Synchrony, and Discover routinely pay 4.00–4.50% while megabanks pay 0.05%.

Better alternatives at higher APY

If branch access isn’t critical for you, these alternatives currently pay materially more on the same FDIC-insured deposit:

Marcus 1-Year CD — ~4.50%
Ally 5-Year CD — ~4.00%
Synchrony 5-Year CD — ~4.00%

When a MYGA beats this CD

A Multi-Year Guaranteed Annuity (MYGA) is the insurance-industry equivalent of a CD: lock a fixed rate for a fixed term, principal-protected. The pricing gap vs. a megabank CD is dramatic.

Math at $250,000 over 5 years:

Prosperity 5-year Standard CD pays 0.15%. A 5-year MYGA pays ~5.50%. On $250,000:

Prosperity 5-Year CD @ 0.15%: $251,879 ending balance
5-Year MYGA @ 5.50%: $326,740 ending balance
Difference: $74,861 — in favor of the MYGA

MYGAs also defer tax on interest until withdrawal — CDs are taxed annually as ordinary income whether you touch the interest or not. The trade-off: MYGAs have a fixed surrender schedule (usually with 10%/yr free withdrawal); CDs have shorter penalty periods. For taxable retirement money you don’t plan to touch, the MYGA almost always wins. See CD vs MYGA Comparison.

Before you lock in — see what a MYGA pays at the same term

Hans Goldstein, independent licensed insurance producer.

If you’re looking at a Prosperity Bank CD, you should see what an A-rated MYGA pays for the same lock-up. The yield gap is often 100–500 basis points — on a $250K deposit over 5 years that’s real money.
