La réponse en bref
A 2-year CD fixes your rate for 24 months, and it is the first term where the interest starts to compound on itself in a way you can see. A $25,000 deposit at 3.95% APY earns $2,014.01 and matures at $27,014.01 — the second year contributes $1,026.51 against the first year's $987.50, because the first year's interest is itself earning. The decision here is not against savings, it is against rolling a one-year CD twice. At today's inverted pricing, two 12-month CDs at 4.25% produce $27,170.16, beating the two-year lock by $156.15. That gap is the price of certainty: the two-year CD wins the moment the one-year rate in twelve months' time comes in below about 3.65%. Whether you take that trade depends entirely on whether you think short rates are going to fall.
Formule et méthode
A = P(1 + r/n)^(nt), t = 2
Two years of compounding. The second year's interest is larger than the first because it is earned on a bigger balance.
Convert the 24-month rate to a decimal and divide by n.
Raise (1 + r/n) to the power n × 2.
Multiply by the deposit for the maturity value.
Subtract the deposit for the total interest across both years.
To test the alternative, square the one-year growth factor and compare the two results.
Mode d'emploi
Type the amount or drag the slider. Check the balance against the $250,000 FDIC limit — two years of interest on a large deposit can push it over.
Use the rate quoted for the two-year term. On an inverted curve it is frequently below the one-year rate, which is the whole point of the comparison.
The growth chart shows the second year climbing faster than the first. That divergence is compounding, and it is why two years at one rate is not simply twice one year.
Set the term to 12 months at today's one-year rate, square the result mentally, and compare. If rolling wins, you are being asked to pay for rate certainty.

Résultat
The second year pays $39.01 more than the first on an identical rate, purely because it is earned on a balance that now includes year one's interest. That is the entire mechanism of compounding, visible for the first time at this term length.

Résultat
Rolling wins by $156.15 while short rates hold. If the one-year rate falls below roughly 3.65% by the renewal date, the two-year lock would have been the better decision. There is no way to know which — the two-year CD is insurance, and $156.15 is the premium.
Méthodologie
The rolling comparison holds the second one-year rate constant at 4.25%. That is the assumption carrying the result, and it is a scenario rather than a forecast.
The break-even rate is calculated on the second year only, assuming the first year is fixed at 4.25%.
Interest compounds inside the CD. Drawing it monthly lowers the maturity value and removes the second-year compounding effect shown above.
Figures are gross of tax, and a two-year CD generates taxable interest in each of the years it spans — payable before you can access the money.
Les conventions suivent la Regulation DD (12 CFR 1030), qui encadre la façon dont les établissements américains communiquent l'APY des comptes de dépôt. Les dépôts effectués auprès d'établissements assurés sont protégés par la FDIC jusqu'à $250,000 par déposant, par banque et par catégorie de propriété.

Détails
Two years is the shortest term where compounding is visible without a magnifying glass. The second year outpaces the first by $39.01 on $25,000 at 3.95%, and the gap widens with every additional year.
The early withdrawal penalty steps up at this term. Most banks charge 180 days of interest on CDs of a year or more, against 90 days on shorter terms — $486.99 on $25,000 at 3.95%.
Interest is taxable annually even though it is inaccessible. On a two-year CD you will receive two 1099-INT forms and owe tax on interest you cannot withdraw without a penalty.
A two-year CD is a bet that short rates fall. If you have no view on that, a ladder splitting the money between 12 and 24 months captures part of both outcomes and is the more defensible default.
Check the FDIC headroom. A $245,000 deposit at 3.95% is fully insured at opening and matures at $264,737.26, leaving $14,737.26 uninsured — accrued interest counts toward the limit.

Cas d'usage
If you expect cuts, locking two years at today's rate is exactly the right trade — and the $156 you appear to give up now is what buys the protection.
A deposit for a house purchase, a car replacement or a school fee two years out. The date is known, so the lock-up costs nothing and the rate is guaranteed.
The 24-month rung is where most short ladders top out. Combined with 6- and 12-month rungs it produces a maturity every six months without giving up much yield.

At 3.95% APY, $2,014.01 in total — $987.50 in the first year and $1,026.51 in the second, maturing at $27,014.01. The second year pays more because it is earned on a balance that already includes the first year's interest.
