The best 9-month CD rates reach approximately 4.20%–4.35% APY in September 2026, slotting neatly between 6-month and 12-month rates. The 9-month term is less common — not every bank offers it — but it can be a useful middle ground when your timeline falls between the two more standard options.
Rates shown are as of September 2026 and change frequently. Verify current rates directly with the institution before opening.
Best 9-Month CD Rates (September 2026)
| Institution Type | Approximate 9-Month APY |
|---|---|
| Online banks (top offers) | 4.20%–4.35% |
| Credit unions | 4.05%–4.25% |
| Brokered CDs (Fidelity, Schwab) | 4.10%–4.30% |
| Traditional big banks | 0.01%–1.00% |
Brokered CD platforms aggregate 9-month-equivalent offerings from multiple banks and are worth comparing when hunting this specific term, since fewer standalone banks advertise an exact 9-month CD than 6-month or 12-month terms.
How Much Does a 9-Month CD Earn?
| Deposit | APY | Interest Earned (9 months) |
|---|---|---|
| $5,000 | 4.30% | ~$160 |
| $10,000 | 4.30% | ~$321 |
| $25,000 | 4.30% | ~$802 |
| $50,000 | 4.30% | ~$1,604 |
Figures use the APY compounding convention: A = P(1+APY)^0.75.
9-Month CD vs. 6-Month and 12-Month CDs
| Term | Typical Top APY (Sept 2026) | Interest on $10,000 |
|---|---|---|
| 6 months | 4.15%–4.30% | ~$210 |
| 9 months | 4.20%–4.35% | ~$321 |
| 12 months | 4.30%–4.44% | ~$435 |
The rate difference between terms is typically small — often 0.10 percentage points or less at top institutions. On $10,000, the difference between a 6-month and 9-month CD is roughly $111 in additional interest. The practical question is simpler: how long can you confidently leave the money locked up?
When to Choose a 9-Month CD
A 9-month CD makes sense when:
- You have a specific cash need in approximately 9 months (a payment due, a renovation planned, a purchase scheduled)
- The 9-month rate at your target institution is meaningfully better than its 6-month rate
- You’re building a CD ladder and need a rung at this exact maturity date
- You want to avoid locking in for a full 12 months in case rates rise in the next year
A 9-month CD is less useful when:
- You find 6-month or 12-month rates at other institutions that exceed the 9-month rate you’re evaluating
- Your timeline is flexible — in which case the more liquid 12-month term at a top online bank is typically better
9-Month CD vs. High-Yield Savings Account
As of September 2026, high-yield savings accounts pay roughly 4.00%–4.40% APY on a variable basis (verify current rates). A 9-month CD at 4.30% APY is comparable — but the CD locks in that rate, while a HYSA rate can change at any time.
If you think interest rates will fall over the next 9 months, a CD locks in today’s rate and protects you from that decline. If you think rates will rise, a HYSA or the 6-month CD gives you more flexibility to reinvest at higher rates sooner.
Early Withdrawal Penalty
Typical 9-month CD early withdrawal penalty: 60–90 days of interest.
On a $10,000 CD at 4.30% APY, 90 days of interest is approximately $107. If you open a 9-month CD and need funds after 3 months, you would receive your $10,000 back plus the roughly 3 months of interest you earned minus the 90-day penalty — netting roughly zero net interest income. This underscores the importance of knowing your timeline before opening.
