Jumbo CD Rates: Do Larger Deposits Actually Earn More? (May 2026)
The short answer: usually not. Most major online banks offer identical rates whether you deposit $1,000 or $100,000. The jumbo CD premium is a relic of an era when banks needed to attract large deposits. In 2026, online banks have nearly eliminated it. Here is the actual data.
Standard vs Jumbo: 1-Year CD Rate Comparison
| Bank | Standard APY | Jumbo APY | Premium | Jumbo Minimum |
|---|---|---|---|---|
| Discover | 4.05% | 4.05% | None | $100,000 |
| Capital One | 3.95% | 3.95% | None | $100,000 |
| Ally | 4.00% | 4.00% | None | No jumbo tier |
| Marcus | 4.05% | 4.05% | None | No jumbo tier |
| Synchrony | 3.90% | 3.90% | None | No jumbo tier |
| First Internet Bank | 3.86% | 3.92% | +6 bps | $100,000 |
| Connexus Credit Union | 4.01% | 4.11% | +10 bps | $100,000 |
bps = basis points (1 bps = 0.01%). Most major online banks offer zero premium for larger deposits.
When Jumbo CDs Make Sense
Credit unions: Some credit unions (like Connexus) still offer meaningful jumbo premiums of 0.05%-0.10%. If you are eligible for membership, this can be worth it.
Relationship pricing: Traditional banks sometimes offer rate bonuses for customers who maintain large deposit relationships. If you already bank with a large institution, ask about their CD specials for existing customers.
Negotiation leverage: With $250K+ in deposits, some banks will negotiate rates that are not publicly advertised. This is more common with private banking divisions than retail branches.

Frequently Asked Questions
What is a jumbo CD?▾
A jumbo CD requires a minimum deposit of $100,000 or more. Historically, banks offered higher rates for larger deposits. In 2026, most online banks have eliminated the jumbo premium, offering the same rate regardless of deposit size. Some credit unions and traditional banks still offer a small premium of 0.05%-0.10%.
Is a jumbo CD worth it?▾
In most cases, no. The rate premium at major online banks is zero. Even where a premium exists (like Connexus Credit Union), it is typically 0.10% or less. On $100,000, that is $100 per year. You are better off splitting across multiple banks for FDIC coverage or using brokered CDs for automatic FDIC spread.
What about FDIC limits for jumbo CDs?▾
FDIC insurance covers $250,000 per depositor, per bank. A $100,000 jumbo CD at a single bank is fully covered. But if you have $500,000, you need to spread across at least two banks. Brokered CDs through Fidelity or Schwab automatically split your deposit across multiple issuing banks for full FDIC coverage.
