짧은 답변
A 10-year CD locks a fixed rate for a decade, and it is the term where compounding finally dominates: a $25,000 deposit at 3.60% APY earns $10,607.18 and matures at $35,607.18, with more than $1,600 of that coming from interest earned on interest. On $100,000 the same term matures at $142,428.71. The catch is that ten-year CDs rarely pay a premium for the extra time — the rate is often below the five-year and well below the one-year. Rolling a one-year CD at 4.25% for the decade would produce $37,905.36, or $2,298.18 more, and the ten-year CD only wins if the average short rate over ten years falls below 3.60%. Inflation then takes another bite: at 2.5% a year, the $35,607.18 is worth $27,816.27 in today's money, a real gain of $2,816.27 on $25,000 across ten years. The term makes sense as insurance against a sustained low-rate decade, and for very little else.
공식과 방법
A = P(1 + r/n)^(nt), t = 10
A decade of compounding. On $25,000 at 3.60% it contributes $1,607.18 above what simple interest would have paid.
Convert the 120-month rate to a decimal and divide by n.
Raise (1 + r/n) to the power n × 10.
Multiply by the deposit for the maturity value.
Subtract the deposit for the decade's total interest.
Divide by (1 + inflation)^10 to restate the result in today's money.
가이드
Type the amount or drag the slider. Over ten years the accrued interest is large enough that a deposit comfortably under $250,000 can mature above the FDIC limit.
Ten-year CDs are uncommon; the rate frequently sits below the five-year term. If it does, that is the market telling you it does not want your money for a decade.
Switch the term chip to 60 or 12 months. If the shorter terms pay more, the ten-year CD is only worth it as protection against rates falling.
Divide the maturity value by (1 + inflation) to the power ten. Over a decade this changes the answer more than the rate does.

The deposit grows by 42.4% and compounding supplies $1,607.18 of the $10,607.18 — 15.2% of the total return. This is what a decade of compounding looks like, and it is the one genuine argument for the term.

Rolling wins by $2,298.18 while short rates hold, and the ten-year CD only comes out ahead if the average one-year rate across the decade falls below 3.60%. After 2.5% inflation the real gain on $25,000 is $2,816.27 over ten years — about 1.07% a year.
계산 방법
The rate is fixed for all 120 months. Ten-year CDs are almost always fixed, but callable versions exist and can be redeemed by the bank early — check before assuming the rate is yours for the decade.
The rolling comparison holds the one-year rate at 4.25% for ten consecutive years. Over a decade that is a scenario, not a forecast; it is shown to define the break-even, which is 3.60%.
Inflation is assumed at a constant 2.5%. The actual figure over ten years will differ and is the single largest source of uncertainty in the real return.
Figures are gross of tax. Ten years of ordinary-income tax on interest you cannot access is a substantial and often overlooked cost.
계산 관행은 미국 금융기관이 예금 계좌의 APY를 공시하는 방식을 규정한 Regulation DD(12 CFR 1030)를 따릅니다. 예금자보호 대상 기관의 예금은 예금자별, 은행별, 소유 형태별로 $250,000까지 FDIC의 보호를 받습니다.

세부 사항
Ten-year CDs frequently pay less than five-year ones. The term premium that ought to exist for a decade of illiquidity generally does not, because banks have limited appetite for deposits they must pay a fixed rate on for that long.
Callable CDs are common at long terms. If rates fall the bank redeems the CD and you reinvest at the lower rate; if rates rise you are locked in. The optionality runs one way, and the extra yield is the price of it.
The early withdrawal penalty is severe — commonly 365 to 730 days of interest. On $25,000 at 3.60%, a 730-day penalty is $1,800.00, so an exit at year three nets $25,998.37 against $27,798.37 held.
Ten years of accrued interest can breach FDIC coverage on its own. A $200,000 deposit at 3.60% matures at $284,857 — around $34,857 of it uninsured unless the account is restructured before then.
A Treasury note or a long ladder does the same job with more flexibility. The ten-year CD's only genuine edge is that its principal never moves in value, which matters if you might have to look at the balance rather than sell it.

활용 사례
A decade at today's rate is the strongest expression of that view available in an insured product. If you are right, the $2,298.18 you appear to give up becomes a substantial gain.
For money genuinely not needed for ten years, a CD guarantees the figure. What it does not do is grow ahead of inflation by much — 1.07% a year in real terms on these numbers.
Check it against the five-year and one-year terms first. If the ten-year pays less, the extra nine years of lock-up are buying you nothing but certainty.
