How much will a $10,000 CD earn in a year?

At 4.35% APY (a competitive rate as of September 2026), a $10,000 CD earns $435 in one year. At 4.50% APY, it earns $450. At a typical big bank rate of 0.50%, it earns only $50. The difference between the best and worst CD rates on a $10,000 deposit is roughly $400 per year.

Are CDs worth it in 2026?

CDs are worth it when rates are competitive (above 4% APY) and you have cash you won't need for a specific period. They guarantee a fixed return with FDIC insurance up to $250,000. However, if rates are expected to rise, shorter-term CDs or high-yield savings may be better to avoid locking in lower rates.

What is a CD ladder and how does it work?

A CD ladder splits your deposit across multiple CDs with staggered maturity dates (e.g., 1-year, 2-year, 3-year, 4-year, 5-year). As each CD matures, you reinvest it at the longest term. This gives you regular access to funds while capturing higher long-term rates. A $50,000 ladder across 5 terms means $10,000 matures every year.

Figures use the APY compounding convention: A = P(1+APY)^years.

At 5.00% APY (Illustrative Higher-Rate Scenario)

Deposit	6 Months	1 Year	2 Years	3 Years	5 Years
$1,000	$25	$50	$103	$158	$276
$5,000	$124	$250	$513	$789	$1,381
$10,000	$248	$500	$1,025	$1,577	$2,763
$25,000	$620	$1,250	$2,563	$3,941	$6,907

$100,000	$2,480	$5,000	$10,250	$15,763	$27,628

As of September 2026, top nationally available CD rates generally run below 5.00% APY across most terms — this scenario is illustrative for comparison, not a current top-rate claim. Check best CD rates for current offers.

At 0.50% APY (Typical Big Bank Rate)

Deposit	6 Months	1 Year	2 Years	3 Years	5 Years
$10,000	$25	$50	$100	$151	$253
$25,000	$63	$125	$251	$377	$631
$50,000	$125	$250	$501	$754	$1,263
$100,000	$250	$500	$1,003	$1,508	$2,525

The difference matters: $100,000 for 5 years at 4.35% earns $23,726 vs only $2,525 at 0.50%. That’s over $21,000 more just for choosing a better bank.

CD Ladder Strategy

How a 5-Year CD Ladder Works

Split $50,000 across 5 CDs with staggered maturity dates, using illustrative September 2026 top rates (confirm current rates before opening):

CD	Amount	Term	Illustrative APY	Maturity	Interest Earned
CD 1	$10,000	1 year	4.35%	Year 1 → Reinvest for 5 years	$435
CD 2	$10,000	2 years	4.35%	Year 2 → Reinvest for 5 years	$889
CD 3	$10,000	3 years	4.40%	Year 3 → Reinvest for 5 years	$1,379
CD 4	$10,000	4 years	4.45%	Year 4 → Reinvest for 5 years	$1,902
CD 5	$10,000	5 years	4.45%	Year 5 → Reinvest for 5 years	$2,432

Benefits: After year 1, you have $10,000 maturing every year (liquidity) while earning long-term rates.

CD Ladder vs Single CD vs High-Yield Savings

Strategy	$50,000 Over 5 Years	Total Interest (approx.)	Access to Cash
Single 5-year CD at 4.45%	One lump at maturity	~$12,160	None for 5 years
5-year CD ladder (see above)	$10K matures yearly	~$7,037 (sum of individual rungs’ interest, not directly comparable — each rung matures and is reinvested at then-current rates)	$10K per year
High-yield savings at ~4.20% (verify current rate)	Anytime withdrawal	~$11,420	Anytime
Checking account at 0.01%	Anytime	~$25	Anytime

In a declining- or flat-rate environment, locking in with CDs can win. In a stable/rising rate environment, HYSAs may keep pace or outpace CDs. The ladder row is not a true apples-to-apples total since each rung’s future reinvestment rate is unknown — it’s included to illustrate the liquidity trade-off, not a precise 5-year total.

CD vs Other Safe Investments

Investment	Approx. Yield (Sept 2026)	FDIC Insured	Liquidity	Tax Treatment
1-Year CD	4.30–4.44%	Yes ($250K)	Locked (early withdrawal penalty, varies by bank)	Federal + state income tax
High-yield savings	~4.00–4.40% (verify current rate)	Yes ($250K)	Anytime	Federal + state income tax
Money market account	~3.80–4.20% (verify current rate)	Yes ($250K)	Limited (check current transfer limits)	Federal + state income tax
1-Year Treasury	~4.37% (per Fed H.15, Sept 14, 2026)	N/A (gov backed)	Sell on secondary market	Federal only (no state tax)
I Bonds	4.26% composite (May–Oct 2026 rate, per TreasuryDirect)	N/A (gov backed)	1-year lockup, then flexible (penalty before 5 years)	Federal only (no state tax)
Series EE Bonds	2.40% fixed (bonds issued May–Oct 2026, per TreasuryDirect)	N/A (gov backed)	1-year lockup	Federal only (no state tax)

Early Withdrawal Penalties

Penalty formulas vary significantly by bank — there is no industry-standard schedule. As an illustrative example, using a $10,000 CD at 4.35% APY:

CD Term	Illustrative Penalty	Approx. Amount Lost on $10,000 at 4.35%
3 months	~1 month interest	~$36
6 months	~3 months interest	~$109
1 year	~6 months interest	~$218
2 years	~6–9 months interest	~$218–$326
3 years	~9–12 months interest	~$326–$435
5 years	~12–18 months interest	~$435–$653

Confirm the exact penalty schedule with your specific bank — Capital One 360, for example, charges a flat 3 months of interest for terms of 12 months or less and 6 months for longer terms, which is a different structure than the tiered illustration above. Some banks offer no-penalty CDs with somewhat lower rates. Worth considering if you might need access.

CD Interest and Taxes

Tax Bracket	Tax on $5,000 CD Interest	After-Tax Return (4.35% CD)
10%	$500	3.92%
12%	$600	3.83%
22%	$1,100	3.39%
24%	$1,200	3.31%
32%	$1,600	2.96%
35%	$1,750	2.83%
37%	$1,850	2.74%

CD interest is taxed as ordinary income. Consider holding CDs in tax-advantaged accounts (IRA CD) to defer or eliminate taxes.

When CDs Make Sense

Scenario	Why CDs Work
Saving for a house (1-3 years out)	Guaranteed return, no market risk
Emergency fund tier 2	3-6 months expenses in accessible savings, remainder in CDs
Rates are high and might fall further	Lock in today’s rates before they potentially drop
You need to separate savings from spending	Locked money = can’t impulsively spend it
Near retirement and need safety	Preserve capital with guaranteed yield
FDIC insurance matters	Full government backing up to $250K

When to Skip CDs

Scenario	Better Alternative
Need access to cash anytime	High-yield savings account
Investing for 5+ years	Diversified stock index funds (higher expected returns, but with market risk)
Want state tax savings	Treasury bills/notes (exempt from state tax)
Rates are rising	Shorter-term CDs or HYSA to capture higher rates
Large amounts (over $250K)	Treasuries (no FDIC limit) or spread across banks
