The best 1-year CD rates in September 2026 are paying 4.30%–4.44% APY at online banks and credit unions. On a $10,000 deposit, that’s $430–$444 in guaranteed interest over 12 months — with zero investment risk.
Rates shown are as of September 2026 and are sourced from Bankrate, CNBC Select, and WalletHub rate surveys published this month. CD rates change frequently — verify the current rate directly with the institution before opening an account.
Best 1-Year CD Rates — September 2026
| Institution | APY | Minimum Deposit | Early Withdrawal Penalty |
|---|---|---|---|
| Top online banks/CUs | 4.30%–4.44% | $0–$10,000 | 90–180 days interest |
| Mid-tier online banks | 4.00%–4.30% | $0–$2,500 | 90–150 days interest |
| National average (FDIC, Aug 2026) | 1.71% | Varies | Varies |
| Traditional big banks | 0.01%–0.50% | $500–$1,000 | 90–180 days interest |
The FDIC publishes national average deposit rates monthly (most recent release: August 17, 2026). The top rates come from online banks that operate with lower overhead and compete actively for deposits. Always verify rates at the institution’s website — they change frequently.
How to Find the Best Rate
Look for institutions that are:
- FDIC-insured (banks) or NCUA-insured (credit unions) — both protect deposits up to $250,000 per depositor
- Paying at or near 4.30% APY for a 1-year term
- Charging no more than 180 days of interest for early withdrawal
The big-four banks (Chase, Bank of America, Wells Fargo, Citibank) typically pay 0.01%–0.50% APY on 1-year CDs — a fraction of what online institutions offer. Switching to a top online bank can add $250–$400 in interest per $10,000 over 12 months.
What a $10,000 1-Year CD Earns
| APY | Interest Earned in 12 Months | Total Value at Maturity |
|---|---|---|
| 0.50% (big bank typical) | $50 | $10,050 |
| 1.71% (national average) | $171 | $10,171 |
| 4.30% | $430 | $10,430 |
| 4.35% | $435 | $10,435 |
| 4.44% | $444 | $10,444 |
CDs compound interest — most 1-year CDs compound daily and credit interest at maturity or monthly. Check whether interest is compounded daily, monthly, or at maturity, since this affects your actual earnings slightly.
Example: Sarah deposits $25,000 into a 1-year CD at 4.35% APY. At maturity, she receives $25,000 + $1,087.50 in interest = $26,087.50. If she had put the same money in a traditional bank 1-year CD at 0.25% APY, she’d receive only $25,062.50 — about $1,025 less.
Is a 1-Year CD Right for You?
A 1-year CD makes sense if:
- You have money you won’t need for 12 months — emergency funds, savings earmarked for a specific goal
- You want to lock in today’s rates before the Fed cuts further
- You want FDIC-guaranteed returns with no market risk
A 1-year CD is not the right choice if:
- You might need the funds before maturity (the early withdrawal penalty erodes your returns)
- You believe rates will rise significantly (locking in now means missing higher rates later)
- You need monthly income — most CDs pay interest at maturity or reinvest it automatically
1-Year CD vs. High-Yield Savings Account
| Feature | 1-Year CD | High-Yield Savings Account |
|---|---|---|
| Current top rate | 4.30%–4.44% APY | Roughly 4.00%–4.40% APY (verify current rate — HYSA rates move with the Fed) |
| Rate guaranteed? | Yes — locked for 12 months | No — can change any time |
| Withdraw anytime? | No — penalty applies | Yes |
| FDIC insured? | Yes (up to $250K) | Yes (up to $250K) |
| Best for | Rate certainty, 12-month timeline | Flexibility, emergency funds |
In September 2026, top high-yield savings accounts pay rates in a similar band to 1-year CDs. The key difference: if the Fed cuts rates further, your savings account rate will drop automatically while your CD rate stays locked. If you don’t need immediate access to the funds, a 1-year CD offers better rate protection.
When Is the Best Time to Open a 1-Year CD?
The best time to open a 1-year CD is when rates are near a cyclical peak — before the Fed cuts further. Rates have already come down substantially from the 2024 peak of 5.25%–5.50%. The federal funds rate has been at 3.50%–3.75% through most of 2026 after a series of cuts.
Acting now locks in today’s rates. Waiting risks opening a 1-year CD at a lower rate if the Fed cuts again.
If you’re uncertain about timing, consider a CD ladder: split your money into multiple CDs with different maturity dates (e.g., 3-month, 6-month, 12-month, 18-month). This gives you rate exposure at several points in the cycle and regular liquidity.
1-Year CD vs. Other Terms
| CD Term | Typical Top Rate (September 2026) | Best For |
|---|---|---|
| 3 months | 3.90%–4.25% APY | Very short-term parking |
| 6 months | 4.15%–4.30% APY | Short-term with slightly less flexibility |
| 1 year | 4.30%–4.44% APY | Sweet spot of rate and flexibility |
| 2 years | 4.30%–4.40% APY | Medium-term lockup |
| 3 years | 4.30%–4.50% APY | Locking in current rates longer |
| 5 years | 4.30%–4.50% APY | Long-term rate certainty |
By September 2026 the CD yield curve has largely flattened: 1-year rates no longer carry the clear premium over 3- and 5-year rates that they did earlier in the year. Longer-term CDs now pay about the same as, or slightly more than, the 1-year term at several top-rate institutions — because banks are locking in deposit costs before rates potentially fall further. Confirm the current curve shape at the time you’re shopping, since it can shift with each Fed meeting.
How to Open a 1-Year CD
- Compare rates — use the FDIC’s monthly rate table or comparison sites, then verify directly on the bank’s website
- Confirm FDIC/NCUA insurance — all legitimate US banks and credit unions participating in federal deposit insurance programs qualify
- Fund the account — most online banks allow ACH transfer from your existing bank account; funds typically arrive in 1–3 business days
- Set a maturity reminder — most banks automatically roll your CD into a new CD at the current rate unless you instruct otherwise. Set a calendar reminder 7–10 days before maturity to review your options
- Decide at maturity — you can withdraw, renew at the current rate, or switch to a different term
Most banks give you a 10-day grace period at maturity to change your mind without penalty.
