The usual way to frame this (“which pays more?”) produces the wrong decision surprisingly often. A CD paying more than your savings account is only better if you actually leave the money alone for the full term. Break it early, and the penalty can hand back more than the extra interest ever earned you.
So the real question is narrower: can you name the date you need this money?
What you’re actually trading
High-yield savings gives you a variable rate and instant access. The bank can cut the rate tomorrow; you can withdraw tomorrow. Symmetrical, in a way.
A CD gives you a fixed rate and no access. The bank can’t cut your rate for the whole term; you can’t get the money out without paying for it. That’s the entire product.
Everything else (which pays more this week, which bank has the nicer app) is detail on top of that trade.

Two things jump out of that curve.
The one-month CD is a trap on average. At 0.23% it paid less than the average savings account’s 0.38%, for the privilege of locking your money up. Short CDs exist for cash-management reasons, not for savers.
The curve peaks at twelve months and then falls. A 60-month CD averaged 1.36%, below the 12-month’s 1.68%. You were being offered less to commit for five times as long, because banks expect rates to be lower in a few years and won’t promise today’s rate that far out.
The trap in reading this table is assuming it describes your options. It doesn’t. These are averages weighted by deposits, dragged down by the branch banks where most money sits. A genuinely competitive savings account can out-earn the average CD in that chart while keeping your money reachable — which is exactly why “CDs pay more” is a category-level claim that frequently fails at the account level.
Run the penalty maths before the interest maths
This is the step people skip, and it’s the one that decides the outcome.
Take $10,000 for twelve months. At the 1.68% average CD rate that’s roughly $168 of interest. At 0.38% savings, about $38. A gap of $130 — real, but not enormous.
Now assume you need the money in month seven. A three-month interest penalty on that CD is roughly $42, so you keep around $56 instead of $168, and the savings account you dismissed would have paid you about $22 with no drama. The CD still wins, narrowly. Because the term was short and the penalty modest.
Redo it with a five-year CD and a twelve-month penalty. Break it in year one and the penalty exceeds everything you’ve earned; the bank takes the difference out of your principal. Same product, completely different risk, and the only variable that changed was the term.
Rule of thumb: the longer the term, the more the penalty — not the rate — should drive your decision.
Which one, by situation
| Your situation | Pick |
|---|---|
| Emergency fund | Savings. Emergencies don’t check maturity dates. |
| House deposit, completion in ~9 months | CD matching the term |
| Saving for something, no date yet | Savings |
| Tax bill due in April | CD maturing in March |
| You’ll add to it monthly | Savings: most CDs don’t accept top-ups |
That last row catches people out. A CD is generally a one-time deposit. If your plan involves paying in every payday, a CD is the wrong container, no matter what it pays.
The maturity default that quietly costs money
When a CD matures you typically get a grace period of a week or two. Miss it, and most banks roll the balance into a fresh CD of the same length at whatever rate is current that day. That may be nothing like the rate you originally signed up for, and it locks you in again.
Two minutes of prevention: put the maturity date in your calendar with a reminder a fortnight before, and decide then whether to take the money, roll it, or move it. The automatic roll is the bank’s default, not yours.
If you can’t choose, don’t
Splitting the money is a legitimate answer, not a fudge. Keep the portion you might need in savings, and put the portion you’re confident about into a CD matching your timeline. If you want the CD share to stay semi-liquid, split it across several terms so something matures every few months.
You give up a little rate for a lot of optionality, a fair trade when nobody agrees on where rates go next. Check current CD terms before you commit to a ladder, and if you’re still weighing this against a money market account, that comparison is in the savings guide.
