If you have cash sitting in a regular savings account, you might be leaving money on the table.
Certificates of deposit have been paying well above what most big banks offer on savings for a while now, and the gap is still wide enough to notice.
The catch is that these rates move with the Federal Reserve, and nobody knows exactly how long they'll stay this high.
A CD is a savings product where you agree to leave your money alone for a set period, anywhere from a few months to five years.
In exchange, the bank locks in your interest rate.
Top nationally available CDs have recently been landing in the 4% to 5% range for terms around six months to one year, while a typical big-bank savings account still pays a fraction of that.
The trade-off is simple: the longer you lock in, the more you usually earn, but your money is tied up.
Pull it out early and you'll typically owe an early withdrawal penalty, which can eat several months of interest.
So the first question isn't "which CD pays the most" — it's "when will I actually need this cash?" Rates vary a lot depending on where you look.
Online banks and credit unions tend to offer the most competitive yields because they don't carry the overhead of a branch network.
The big national banks often pay far less, sometimes under 1%, even on longer terms.
On $10,000, the gap between 0.5% and 4.5% is roughly $400 over a single year.
One thing worth knowing: these rates aren't guaranteed to stick around.
The Fed has been signaling that its next moves depend on inflation and jobs data, and CD yields tend to drift down when rate cuts are expected.
Some banks have already trimmed their best offers.
That doesn't mean you should panic and lock up every dollar today, but waiting months to decide can cost you real interest.
First, check what your current bank pays — you may be surprised how low it is.
Second, compare a handful of online banks and credit unions rather than just one.
Third, think about a CD ladder: split your money across several terms so a chunk matures every few months, giving you access without one big penalty risk.
And always confirm the penalty terms before you sign, not after.
If you're saving for something specific — a car, a home repair, next year's tuition — a CD that matures around that date can be a clean fit.
If you might need the money at any moment, a high-yield savings account usually makes more sense, even if the rate is slightly lower.
The best choice depends on your timeline, not just the headline number.
My take: CD rates today are still worth a serious look, but they won't stay this attractive forever.
If you've been meaning to move idle cash somewhere it earns more, doing a little comparison shopping this week beats waiting for a perfect rate that may never come.
Final Thoughts
Just don't lock up money you can't afford to leave alone.
