Best 6-Month CD Rates 2026

Quick answer

A 6-month CD makes sense if you have cash you will not touch for six months and want a guaranteed rate for that stretch. As of October 1, 2026, the best 6-month CD SwitchWize tracked paid about 4.33% APY, against about 4.25% for the best high-yield savings account. That is a small edge, so if you might need the money sooner, stay liquid instead, since breaking a CD early usually costs more than the extra yield. With the Fed raising rates in September 2026, the short term is also a plus: you can reinvest at maturity if rates are higher then. Comparing the best 6-month CD rates 2026 across banks helps you find the right fit for your timeline.

The full picture

A 6-month CD earns a guaranteed rate for six months, full stop. As of today, Synchrony Bank's 6-month CD is paying … APY and Marcus by Goldman Sachs is offering … APY, useful live benchmarks for the tier. If you have cash sitting in a 0.01% checking account or a low-yield savings account, the math is straightforward. The only question is whether you can commit the funds for six months. If you cannot, a no-penalty CD or a high-yield savings account is the better tool. If you can, the six-month CD typically wins on yield and certainty.

What $10,000 earns over 6 months

Rather than showing a static dollar table that goes stale, plug your deposit into our calculator to see exact earnings at today's live rates for any 6-month CD, HYSA, or the national average.

Calculate your 6-month CD earnings

For context, the national savings average is just 0.38% APY. As of October 1, 2026, $10,000 in the best 6-month CD (about 4.33% APY) earned about $214 over six months, compared with about $19 at the 0.38% national average.

Liquidity penalty test: what early withdrawal actually costs

Before opening a 6-month CD, run this test. Most 6-month CDs charge 60 to 90 days of interest as an early withdrawal penalty. On a short hold the penalty can exceed the interest earned, meaning you lose money. Use our CD calculator to model early-withdrawal scenarios at today's rates for your specific deposit.

Rules of thumb: the penalty is counted in days of interest, so compare it with how many days you have held the CD.

• Withdraw after 1 month (about 30 days of interest earned): a 60- or 90-day penalty is bigger than what you earned. You come out behind.
• Withdraw after 2 months (about 60 days earned): roughly break even with a 60-day penalty; still about 30 days of interest behind with a 90-day penalty.
• Withdraw after 3 months (about 90 days earned): you keep about 30 days of interest with a 60-day penalty, and roughly break even with a 90-day penalty, far less than high-yield savings would have paid with full access.
• Hold the full 6 months: no penalty, full interest. This is the only scenario where the CD reliably wins.

On $10,000 at 4.33% APY, one day of interest is about $1.16, so a 90-day penalty is about $105. Some banks deduct a penalty larger than the interest earned from your principal.

Conclusion: if there is any meaningful chance you will need the funds in the first two months, a HYSA or no-penalty CD is a better fit. Run your own numbers with our CD calculator before committing.

When a 6-month CD makes sense

• You have cash you will not need for at least six months (emergency fund is separately funded).
• You want a guaranteed rate for six months but don't want to lock in for long. The Fed raised rates on September 16, 2026 (the fed funds upper bound is currently 4.00%), and its projections show one more hike penciled in for 2026, so a short term lets you reinvest at maturity if rates are higher.
• You are building a CD ladder with a 6-month rung for short-term liquidity.
• You have a specific financial goal with a known date 4 to 8 months away (tax bill, vacation, equipment purchase).

When to skip a 6-month CD

• Your emergency fund is not fully funded. Never lock emergency cash in a CD.
• You are unsure whether you will need the funds before maturity.
• The CD rate is within a few basis points of the best HYSA rate. The best high-yield savings accounts are currently paying up to 4.40% APY, so if the spread is negligible, HYSA liquidity is worth the small yield difference.
• You are comfortable with T-bills. Compare a 6-month Treasury bill with top CD rates (the 3-month Treasury yield sits at 4.30% and the 1-year at 4.40%); T-bill interest is exempt from state income tax, which can tip the math in high-tax states. See our CD vs bond vs Treasury comparison for details.

6-month CD vs. high-yield savings: the real comparison

The CD wins if rates fall after you open. High-yield savings wins if you might need access, or if rates keep rising and your bank passes the increase along. As of October 1, 2026, the best of each paid similar rates (about 4.33% for a 6-month CD vs. about 4.25% for savings). The decision comes down to liquidity certainty and rate outlook.

Choose X if

• Choose a 6-month CD if you have a specific short-term goal, want a guaranteed rate, and can commit the funds.
• Choose a HYSA if you value daily access or are not certain you can leave the funds untouched.
• Choose a no-penalty CD if you want a fixed rate without the lockup risk and the no-penalty rate is close to savings rates. Compare carefully: Ally's 11-month No Penalty CD was 2.80% APY on September 30, 2026, well below top savings accounts.
• Choose a T-bill if you pay high state income taxes (T-bill interest is exempt from state tax).
• Build a CD ladder if you want a mix of short-term access and guaranteed yield at multiple maturities.
