Jumbo CD rates in September 2026 run roughly 3.90%–4.40% APY depending on term and institution, on deposits typically starting at $25,000–$100,000. On $100,000, a 1-year jumbo CD near 4.30% APY earns about $4,300 in guaranteed interest over 12 months — but the honest headline is that jumbo CDs frequently no longer pay more than standard CDs at top online banks.
Rates shown are as of September 2026, based on CNBC Select and WalletHub jumbo CD surveys published this month. Verify the current rate directly with the institution. Check whether standard CD rates at top online banks match jumbo rates before committing to a large minimum.
Representative Jumbo CD Rates — September 2026
| Term | Example Jumbo Offer | APY | Minimum | Standard Top CD APY (for comparison) |
|---|---|---|---|---|
| 6 months | My eBanc | ~4.00% | $100,000 | 4.15%–4.30% |
| 1 year | Credit One Bank | ~4.30% | $100,000 | 4.30%–4.44% |
| 3 years | Merrick Bank | ~4.40% | $25,000 | 4.30%–4.50% |
| 5 years | Merrick Bank | ~4.30% | $25,000 | 4.30%–4.50% |
This is a snapshot of representative offers, not an exhaustive ranking. Jumbo CD minimums are no longer standardized at exactly $100,000 — some banks use $25,000 as their jumbo threshold. Rates and offers change frequently; verify directly with each institution.
What $100,000 Earns in a Jumbo CD
| Term | Rate | Interest Earned | Total at Maturity |
|---|---|---|---|
| 6 months | 4.00% | $1,980 | $101,980 |
| 1 year | 4.30% | $4,300 | $104,300 |
| 3 years | 4.40% | $13,789 | $113,789 |
| 5 years | 4.30% | $23,430 | $123,430 |
Figures use the APY compounding convention: A = P(1+APY)^years. Actual amounts vary by institution.
Example: Patricia receives a $150,000 inheritance and wants a safe, FDIC-insured place to grow it for 12 months while she decides on longer-term investments. Before opening a jumbo CD, she compares the jumbo rate to standard CD rates at top online banks and finds a standard 1-year CD paying about the same 4.30%–4.40% APY with no $100,000 minimum. She splits the $150,000 across two FDIC-insured institutions in standard CDs, keeping each institution’s balance under the $250,000 insurance limit.
Are Jumbo CDs Actually Better?
The honest answer: usually not, in the current market.
At some traditional brick-and-mortar banks, jumbo CDs still pay somewhat more than their own standard CDs. But the more relevant comparison is jumbo rates versus the best standard CD rates available anywhere — and in September 2026, top standard CD rates from online banks (4.30%–4.50% APY across most terms) are competitive with, or better than, many advertised jumbo offers.
Before opening a jumbo CD, compare:
- The jumbo CD rate at your current bank
- The best standard CD rate from top online institutions (no $100,000 minimum required)
If the online bank’s standard rate equals or exceeds the jumbo rate, open the standard CD — and potentially keep your large balance spread across two institutions for better FDIC coverage.
FDIC Coverage for Jumbo CDs
FDIC insurance covers $250,000 per depositor, per institution, per ownership category. For large jumbo CD depositors:
| Deposit Amount | Insurance Situation | Solution |
|---|---|---|
| $100,000 | Fully insured (single account) | No action needed |
| $250,000 | Fully insured (single account) | No action needed |
| $300,000 | $50,000 is uninsured | Split across two banks |
| $500,000 | Joint account (2 owners): fully insured | Use joint ownership |
| $1,000,000+ | Requires multiple banks | IntraFi network |
Ownership categories that each receive separate $250,000 coverage:
- Single accounts (you only)
- Joint accounts (adds $250,000 per co-owner)
- IRAs and certain other retirement accounts
- Trust accounts (coverage rules depend on the number of beneficiaries — consult FDIC’s EDIE calculator for exact figures)
For deposits over $500,000, consider the IntraFi network (formerly CDARS), which spreads deposits across its member bank network to provide multi-million dollar FDIC coverage through a single account relationship.
Jumbo CD vs. Standard CD: A Side-by-Side
| Feature | Jumbo CD | Standard CD (Top Online Bank) |
|---|---|---|
| Minimum deposit | $25,000–$100,000 | $0–$2,500 |
| Typical 1-year APY (Sept 2026) | ~4.30% | 4.30%–4.44% |
| FDIC insured? | Yes (up to $250K) | Yes (up to $250K) |
| Early withdrawal | Penalty structure varies by bank | Penalty structure varies by bank |
| Rate premium for large deposit | Not reliable — verify before assuming | N/A — already at top rate |
This comparison shows why many large depositors default to top online banks’ standard CDs instead of jumbo CDs — the rate premium, when it exists at all, often doesn’t compensate for the loss of flexibility from a large minimum requirement.
When Jumbo CDs Make Sense
A jumbo CD is the right call when:
- Your existing bank offers a verified, meaningful rate premium over standard rates for large deposits
- You’re committed to keeping the funds at a specific FDIC-insured institution and can verify the full deposit is within the $250,000 insurance limit (or spread appropriately)
- You need a single institution relationship for estate or trust management purposes
