How Much Does a Jumbo CD Earn?
A jumbo CD is a certificate of deposit with a large minimum deposit — typically $100,000 or more. The calculator above is preset to a $100,000 jumbo deposit. Enter your exact balance, APY, and term to see your return.
Here is what a jumbo CD earns at a typical 2026 rate of 4.60% APY (compounded daily) across common terms:
| Deposit | Term | Interest Earned | Maturity Value |
|---|---|---|---|
| $100,000 | 6 months | $2,274 | $102,274 |
| $100,000 | 1 year | $4,707 | $104,707 |
| $250,000 | 1 year | $11,768 | $261,768 |
| $500,000 | 1 year | $23,536 | $523,536 |
At these balances, even small differences in APY matter enormously. A 0.25% higher rate on $250,000 over one year is an extra $625 — which is why comparing jumbo CD rates across banks is well worth the effort.
Jumbo CD Rates in 2026: Is the Premium Worth It?
Historically, jumbo CDs paid noticeably higher rates than standard CDs as a reward for the larger deposit. In 2026, that premium has largely disappeared. Many online banks now pay nearly identical APYs regardless of deposit size — sometimes a standard CD even beats a jumbo at the same bank.
As of mid-2026, jumbo CD rates typically range from 4.25% to 4.75% APY, roughly in line with standard CDs. Before assuming a jumbo CD is the best home for a large deposit, compare it against:
- A standard CD at the same bank — the rate may be equal or better
- Brokered CDs — often offer the most competitive jumbo rates and easy comparison
- A CD ladder — splitting a large balance across terms for liquidity
FDIC Insurance and Jumbo CDs: A Critical Limit
This is the most important thing to understand about jumbo CDs: FDIC insurance only covers $250,000 per depositor, per bank, per ownership category. A jumbo CD above that limit at a single bank is not fully insured.
If you are depositing more than $250,000, protect the excess by:
- Spreading across multiple banks — keep each account at or below $250,000.
- Using different ownership categories — individual, joint, and trust accounts each get separate coverage at the same bank.
- Using a network service — some banks participate in programs (like IntraFi/CDARS) that spread a large deposit across many insured institutions while you deal with one bank.
For example, a $500,000 jumbo CD at one bank in a single name leaves $250,000 uninsured. Splitting it into two $250,000 CDs at two different banks keeps the entire amount protected.
