Ally Bank’s CD rates ranged from 2.70% to 4.15% APY as of September 19, 2026 (verified directly at ally.com and cross-checked via CD Valet’s rate tracker, both dated within the prior week), making it a competitive online bank for certificates of deposit. With no minimum deposit and a range of terms from 3 months to 5 years, Ally is a straightforward choice for savers who want FDIC-insured returns without the rate penalty of a big traditional bank.
Rates shown are as of September 19, 2026 and change frequently — especially following the Federal Reserve’s September 16, 2026 rate hike to 3.75%–4.00%. Verify the current rate directly with Ally Bank before opening an account.
Ally Bank CD Rates by Term (September 19, 2026)
| Term | APY |
|---|---|
| 3 months | 2.70% |
| 6 months | 3.50% |
| 9 months | 3.90% |
| 11 months (No-Penalty CD) | 2.70% |
| 12 months | 4.00% |
| 18 months | 4.15% |
| 2 years (Raise Your Rate, 1x) | 3.00% |
| 3 years | 3.60% |
| 4 years (Raise Your Rate, 2x) | 3.00% |
| 5 years | 4.00% |
Ally’s rate curve isn’t a simple downward slope — the 18-month term currently pays the most (4.15%), while the 2-year and 4-year “Raise Your Rate” CDs pay less (3.00%) in exchange for a one-time or twice-per-term rate-increase option. Confirm current rates at ally.com, since this shape can shift.
How Much Can You Earn?
On a $10,000 deposit at Ally’s 12-month rate of 4.00% APY (as of September 19, 2026):
- After 12 months: ~$10,400 ($400 in interest)
- After 2 years (Raise Your Rate CD at 3.00% APY): ~$10,609 ($609 in interest, compounding annually)
- After 5 years (5-year CD at 4.00% APY): ~$12,167 ($2,167 in interest, compounding annually)
Compare that to a big bank standard CD at 0.05% APY: $10,000 after 12 months would earn just $5 in interest.
Ally’s No-Penalty CD — What Makes It Different
The 11-month No-Penalty CD is one of Ally’s standout products. It works like a standard CD — fixed rate, FDIC insured — but allows you to withdraw your full balance (principal plus all interest earned) without penalty after the first 6 days.
When the no-penalty CD makes sense:
- You’re not certain you’ll need the funds before 11 months, but want the option
- You’re waiting for a large purchase (down payment, tuition, planned expense)
- You want to park cash at a higher rate than a HYSA with the safety of a fixed rate
- You’re waiting to see if rates improve before locking into a longer term
The trade-off: the no-penalty rate is typically 0.25–0.50 percentage points below the standard 12-month CD rate. On $10,000, that’s roughly $25–$50 less per year — a reasonable price for the added flexibility.
Early Withdrawal Penalties
If you need to access funds from a standard Ally CD before it matures, the penalties are:
| Term | Early Withdrawal Penalty |
|---|---|
| 24 months or less | 60 days of interest |
| 25–36 months | 90 days of interest |
| 37–48 months | 120 days of interest |
| 49 months or more | 150 days of interest |
These are moderate penalties compared to some banks that charge 180–365 days of interest on longer terms. However, breaking a CD early always reduces your effective yield — the no-penalty CD eliminates this risk entirely.
Ally vs. Marcus and Discover
| Ally | Marcus by Goldman Sachs | Discover Bank | |
|---|---|---|---|
| 12-month APY (as of 9/19/2026) | 4.00% | 3.90% | No longer independent — merged into Capital One (2025) |
| Minimum deposit | $0 | $500 | N/A |
| No-penalty CD | Yes (11 months) | No | N/A |
| Early withdrawal penalty | 60–150 days | 90–270 days | N/A |
| FDIC insured | Yes | Yes | N/A |
Note on Discover: Discover Bank’s consumer banking business, including its CD products, was acquired by and merged into Capital One in 2025. Discover is no longer a standalone CD option — compare Capital One 360 CDs instead if you were considering Discover.
All three are solid online banks. Ally wins on the no minimum deposit and no-penalty option. Marcus and Discover occasionally edge Ally on specific term rates. If you have $2,500+ and want the highest available rate on a single term, compare all three at the time you open — rates shift frequently.
Ally CD Renewal — What to Watch
When an Ally CD matures, it automatically renews into the same term at the current rate. The grace period is 10 days after the maturity date — you can withdraw, transfer, or change terms without penalty during this window.
The renewing rate is whatever Ally is paying on that term at maturity. If rates have fallen significantly, this could be lower than what you were earning. Set a calendar reminder 30 days before maturity to review your options.
Who Should Open an Ally Bank CD?
Ally CDs are well-suited for:
- New savers — no minimum deposit lowers the barrier to entry
- Savers who want flexibility — the no-penalty CD is one of the best on the market
- People uncomfortable with traditional banks — Ally’s online interface is well-rated and customer service is available 24/7
- CD ladder builders — the range of terms and no minimums make Ally easy to use for a multi-rung ladder
Ally is less ideal if you want to make deposits in person (Ally is online-only) or if you’re comparing against a local credit union that may be offering a higher promotional rate at a given moment.
