CD vs high-yield savings account

A CD trades access for a fixed rate; a high-yield savings account keeps your money available at a rate that can change any time. On Nov 10, 2026, 12-month CDs paid 0.60 to 1.25 points more than the same banks’ savings accounts.

How this page was made: it’s built from each provider’s own terms, rate and fee pages and from regulator sources, all listed at the bottom. We haven’t opened these accounts or products to test them, and we don’t give scores. Every rate shows the day we checked it. Our methodology.

Quick answer

Short answer: use a high-yield savings account for money you might need soon, like an emergency fund, and a CD for money you won’t touch for a set time and want at a guaranteed rate. On Nov 10, 2026, Sallie Mae paid 4.00% APY on savings vs 4.60% on a 12-month CD; Capital One paid 3.20% vs 4.45%.

Last updated Rates checked Nov 10, 2026

We compared each bank’s savings account and 12-month CD using rates from its own pages on Nov 10, 2026. Both products are FDIC-insured bank deposits. This is general information, not advice; we haven’t opened these accounts.

Same bank: savings APY vs 12-month CD APY (Nov 10, 2026)
BankHigh-yield savings12-month CDDifference
Sallie Mae Bank4.00% APY (variable) as of Nov 10, 20264.60% APY (12-month, fixed; $2,500 minimum) as of Nov 10, 2026+0.60 points for the CD
Marcus (Goldman Sachs Bank USA)3.50% APY (variable) as of Nov 10, 20264.40% APY (12-month, fixed; $500 minimum) as of Nov 10, 2026+0.90 points for the CD

How they differ

  • Rate: savings APYs are variable; every bank we checked says its savings rate can change before or after you open. A CD’s rate is fixed for the term once you open it.
  • Access: you can withdraw from savings any time (some banks cap withdrawals, e.g. Sallie Mae at 6 a month). Taking money out of a CD early costs a penalty, for example 90 days of simple interest on a 12-month Synchrony CD or 90 days’ interest on an 11-month or shorter Amex CD.
  • Adding money: you can add to savings whenever you like. CDs are generally funded once; Amex, for example, doesn’t allow additional deposits after the CD is opened, except during the 10-day grace period after it matures.
  • Insurance: the same. Both are deposits covered by the FDIC[11] up to $250,000 per depositor, per bank, per ownership category, and they count together at one bank.

What the gap is worth

On $10,000 for one year, Capital One’s 12-month CD at 4.45% APY would earn about $445, versus about $320 in its savings account at 3.20%, if the savings rate stayed the same all year, which isn’t guaranteed. The extra $125 is what you get for locking the money up. If savings rates rose, the gap would shrink; if they fell, it would grow.

The middle ground: no-penalty CDs

A no-penalty CD fixes the rate but lets you withdraw after a short wait. Marcus showed 4.00% APY on an 11-month No-Penalty CD ($500 minimum; withdrawals allowed starting seven days after funding, full balance only), and Ally showed 2.90% on an 11-month No Penalty CD with no minimum (withdraw any time after the first six days). Compare with the bank’s savings rate before choosing.

Who should skip this

  • Your only emergency fund: keep it in savings so a penalty never stands between you and the money.
  • Money for a purchase with an uncertain date (a house, a car): savings or a no-penalty CD avoids a forced penalty.
  • Money you’ll invest for 5+ years: neither may be the right tool for long-term growth; see our investing guides.

Frequently asked questions

Is a CD better than a high-yield savings account?
Only if you won’t need the money before the CD matures. On Nov 10, 2026, 12-month CDs at Sallie Mae, Marcus and Capital One paid 0.60 to 1.25 percentage points more than the same banks’ savings accounts, but early withdrawal costs a penalty.
Can a high-yield savings rate drop?
Yes. Savings APYs are variable and can change at any time, before or after you open the account. A CD’s rate is fixed for its term.
Are CDs and savings accounts insured the same way?
Yes. Both are deposits covered by FDIC[11] insurance at FDIC-insured banks, up to $250,000 per depositor, per bank, per ownership category, combined with your other deposits in that category at the same bank.
What if I need my CD money early?
You’ll usually pay an early withdrawal penalty, often a set number of days of interest. Synchrony charges 90 days of simple interest on terms of 12 months or less; Amex charges 90 days’ interest under 12 months and 270 days from 12 to under 48 months.

Treasury bills are short-term U.S. government securities that are exempt from state and local income tax. CDs are FDIC-insured bank deposits with a fixed APY and an early withdrawal penalty. Near-identical yields can come out differently after tax.

Best high-yield savings accounts

Every account here is at an FDIC-insured bank, charges no monthly maintenance fee and paid 3.20% APY or more on the bank’s own page on Nov 10, 2026, versus the FDIC’s 0.38% national average for savings. The differences are tiers, minimums and how you move money.

High-yield savings vs money market account

Both are FDIC-insured bank deposits with variable APYs. A money market account usually adds checks or a debit card; a high-yield savings account often pays the same or more. At the three banks we checked on Nov 10, 2026, savings paid the same or more every time.
