- ✦A CD early-withdrawal penalty is usually 3 months of interest on terms of a year or less, and 6 to 12 months on longer terms, set by the bank.
- ✦Breaking a CD pays only when the months of extra interest at the new rate exceed the penalty: breakeven months equals penalty divided by the monthly interest gain.
- ✦A half-point bump with a few months left almost never clears the penalty; a full point with a year or more of term remaining usually does.
The instinct when CD rates climb is to break the old one and grab the new rate. Sometimes that is right. Often the early-withdrawal penalty quietly eats the entire gain, and you end up worse off than if you had waited. The decision is not a feeling, it is one piece of arithmetic. Rates on this page were last verified recently.
The top 12-month CD pays 4.15% right now. Whether moving to it beats your current CD comes down to two numbers: the penalty you forfeit, and the extra interest the higher rate earns over the time you have left.
The breakeven, in one formula
There are only three inputs.
- The penalty. Banks quote it as months of interest. On a $25,000 CD at 4.00%, a 3-month penalty is $25,000 times 4.00% times 3/12, which is $250.
- The monthly interest gain. If the new rate is 0.50 points higher, the extra annual interest on $25,000 is $125, or about $10.40 a month.
- The breakeven. Penalty divided by monthly gain: $250 divided by $10.40 is about 24 months.
If your current CD has fewer than 24 months left, breaking it loses money. If it has more, breaking it wins, and the further past breakeven, the better.
Why small gaps almost never clear it
That example is the trap. A half-point looks like an upgrade, but it moves only $10 a month on $25,000, so it takes two full years to recover a single quarter's penalty. Most people chasing a small bump are breaking a CD with months, not years, left. They forfeit a real penalty to capture a gain that never catches up.
Flip the inputs and the answer flips too. A full-point gap doubles the monthly gain to about $20.80, which halves the breakeven to roughly 12 months. With a longer remaining term, say a 3-year CD you opened recently, the higher rate compounds over enough time to clear the penalty comfortably.
What clears the penalty, what does not
| Situation | Clears the penalty? |
|---|---|
| Small gap (about 0.5 pt), months left | No, the gain never catches up |
| Small gap, years of term remaining | Maybe, run the breakeven |
| Large gap (1 pt or more), a year or more left | Usually yes |
| Any gap, weeks from maturity | No, just wait for it to mature |
Run your own number
- Find your penalty in months of interest from the CD disclosure, and convert it to dollars: balance times your rate times months divided by 12.
- Find the monthly interest gain: balance times the rate difference, divided by 12.
- Divide the penalty by the monthly gain. That is your breakeven in months.
- Compare it to the months left on your CD. More time left than the breakeven means breaking it pays.
If you want to skip this math next time, the no-penalty CD lets you move for free, and a high-yield savings account stays liquid throughout. Both trade a little rate for the freedom to chase one.
Quick answers
Is it worth breaking a CD for a higher rate? Only when the months left on your CD exceed the breakeven: penalty divided by monthly interest gain. Small gaps with little time left lose; large gaps with a long term left win.
How big is the penalty? Usually 3 months of interest on short CDs, up to 12 months on 5-year CDs. It is set by the bank, so check your disclosure.
Can I lose principal? Only if you break it before accrued interest covers the penalty. Most banks take it from interest first.
