Compare a fixed CD rate against a variable savings rate to find the best home for your cash.
Should you lock your money in a CD or keep it liquid in a high yield savings account (HYSA)? This tool starts from today's MonitorBankRates average CD and savings rates, lets you say how much you expect savings rates to move each year while the CD stays fixed, and shows the dollar difference at the end of the term, the savings rate that would make the two tie, and what the CD nets if you had to break it early. Pull current CD rates and high yield savings rates to see what beats the averages right now.

CD vs. High Yield Savings at Today's Average Rates
As of September 21, 2026, the MonitorBankRates national average APY is 2.87% on a 12 month CD and 2.00% on a high yield savings account. A $10,000 deposit grows to about $10,286.70 in the CD after 12 months and to $10,199.60 in the savings account if today's savings rate holds for the full year, so the CD comes out $87.10 ahead. The CD rate is locked for the term while the savings rate can change at any time; if savings rates fall during the year the gap moves in the CD's favor, and if they rise the savings account catches up. A standard savings account at today's 0.82% average would grow to only $10,081.70.
| $10,000 for 12 months at today's MBR national average | APY | Value after 12 months |
|---|---|---|
| 12 month CD (fixed rate) | 2.87% | $10,286.70 |
| High yield savings (variable rate) | 2.00% | $10,199.60 |
| Standard savings (variable rate) | 0.82% | $10,081.70 |
Averages are recalculated every day from the rates banks and credit unions publish, so this example reflects today's market rather than a sample rate. The best CDs and savings accounts pay well above the averages.
CD vs. HYSA: Key Differences
Both accounts are FDIC insured, but they serve different purposes. The main trade off comes down to rate certainty versus liquidity:
- CDs lock in a fixed APY for a set term (3 months to 5 years or more). The rate is guaranteed regardless of what the Federal Reserve does, but you pay a penalty if you withdraw early.
- HYSAs let you withdraw any time without penalty, but the APY is variable; banks adjust it as market rates move. You can lose yield quickly when rates are falling, which is what the drift input models.
- Yield gap. Today the national average 12 month CD pays 2.87% against 2.00% for high yield savings, a gap of 0.87 percentage points in favor of the CD. The best offers in each category are usually well above the average.
How to Use the CD vs. HYSA Calculator
-
Enter your initial deposit
Type in the amount you would put into either the CD or the HYSA. The calculator assumes you deposit the same amount in both for a like for like comparison.
-
Set the CD term
Pick the term of the CD you are considering and the CD APY fills in with today's MonitorBankRates average for that term. Choose a custom term to enter any number of months.
-
Check the CD and savings APYs
Replace the averages with real quotes if you have them, or pick your state to use the state averages. The best nationally available CDs and savings accounts pay well above the averages.
-
Say where you think savings rates are headed
The savings rate is variable, so enter how many percentage points per year you expect it to move. Leave it at zero to compare today's rates head to head, or enter a negative number if you expect cuts. The break even result shows the savings APY that would tie the CD under your assumption.
-
Test an early withdrawal
Turn on the early withdrawal scenario to see what the CD nets if you break it after a set number of months and pay the penalty, compared with the savings balance at the same point.
Which One Is Right for You?
The right choice depends on what kind of money you are parking. Same dollars, different jobs; pick the account that fits the job:
Choose a CD when
- You have a specific timeline (wedding, house down payment, tuition due in 2 years)
- You want to lock in today's rate before the Fed cuts
- You will not need the money before the term ends
- You want to maximize yield on idle cash you do not need access to
- You are laddering (try the CD ladder calculator for that approach)
Choose a HYSA when
- This is your emergency fund and access matters more than yield
- You expect rates to rise (a HYSA captures the increase automatically)
- You are saving for a goal with no fixed deadline
- You might need to dip in unexpectedly
- The CD yield premium over your HYSA is small (under 0.25 percentage points)
The hybrid play: many savers use both. Keep 3 to 6 months of expenses in a HYSA as your emergency fund, then put longer term savings (down payment, future tuition, retirement gap) into CDs to capture the yield premium. You do not have to pick one.
Frequently Asked Questions
Do HYSA rates change?
Yes. High yield savings rates are variable and typically move with the Federal Reserve's federal funds rate. When the Fed cuts rates, HYSA APYs usually fall within weeks. CDs lock in the rate at the time you open the account, regardless of what happens to market rates afterward. The drift input in the calculator lets you model that.
Which pays more right now, a CD or a high yield savings account?
As of September 21, 2026, the MonitorBankRates national average is 2.87% APY on a 12 month CD and 2.00% on a high yield savings account, so on $10,000 for a year the CD earns about $87.10 more at the averages. The averages move with the rate cycle, and the top offers in each category are usually well above them, so compare real quotes before you decide.
Is my money safe in both?
Yes, as long as the bank is FDIC insured (or NCUA insured for credit unions), your deposits are protected up to $250,000 per depositor, per institution, per ownership category. If you have more than that, spread it across multiple banks to keep all of it covered.
Can I lose money in a CD if I withdraw early?
You can lose interest and sometimes a small portion of principal. The early withdrawal penalty is typically 3 to 12 months of interest depending on the term length. If you withdraw before earning that much interest, the penalty eats into your principal. The early withdrawal scenario above shows the net, and our early withdrawal penalty calculator goes into more detail.
Should I open a CD if I think rates will rise?
Generally no. If you lock in a 5 year CD and rates climb, you are stuck with the lower rate or pay a penalty to break it. When rates are rising, HYSAs win because the rate moves up automatically. When rates are falling, CDs win because they preserve today's higher rate. Enter a positive or negative savings rate change per year to see either case.
What is the minimum deposit for each?
HYSAs at most online banks have $0 minimums. CDs typically require $500 to $1,000 minimums per CD, though jumbo CDs may require $100,000. Some institutions offer no minimum CDs at slightly lower rates than their standard CDs.
Are HYSA and CD interest taxable?
Yes. Interest from both accounts is taxed as ordinary income at the federal level (and in most states). Banks send you an interest statement each January showing what you earned. The tax treatment is the same for both products, so there is no advantage either way.
Can I add money to a CD after I open it?
Generally no for traditional CDs; the deposit is fixed at opening. Some banks offer add on CDs that allow additional deposits during the term, usually at slightly lower rates. HYSAs allow unlimited deposits at any time. If you want to keep adding savings monthly, a HYSA is more practical even if a CD's headline rate is higher. See current savings rates to find a HYSA that fits.
