In breve

How much does a 6-month CD earn?

A 6-month CD locks your deposit for half a year at a fixed rate, and at most banks it is the best-priced short term on the sheet — banks compete hardest here because six months is where deposit money is most mobile. At 4.40% APY a $10,000 deposit earns $217.63 and matures at $10,217.63; $25,000 earns $544.08. The half-year term means you receive roughly half the advertised APY: 4.40% APY over six months is about 2.18% of your deposit, not 4.40%. The interesting comparison is not against savings but against the one-year CD. Rolling a 6-month CD twice at 4.40% produces $26,100.00 on $25,000, against $26,062.50 for a single 12-month CD at 4.25% — the shorter term wins by $37.50, provided the rate is still there in six months. That proviso is the entire decision.

Formula e metodo

Come viene calcolato

A = P(1 + r/n)^(nt), t = 0.5

Half a year of compounding. At 4.40% APY that returns about 2.18% of the deposit, not 4.40%.

A
Maturity value after six months
P
Opening deposit
r
Nominal annual rate as a decimal
n
Compounding periods per year (daily = 365)
t
0.5 — six months expressed in years

Passo dopo passo

  1. 1

    Convert the 6-month rate to a decimal and divide by n.

  2. 2

    Raise (1 + r/n) to the power n × 0.5 — about 182 daily credits.

  3. 3

    Multiply by the deposit for the six-month maturity value.

  4. 4

    Subtract the deposit to isolate the interest.

  5. 5

    To test rolling, square the six-month growth factor and compare it against a 12-month CD.

Guida

Come usare questo calcolatore

Quattro dati, risultati in tempo reale. Nulla da inviare e nessuna registrazione.
  1. 1

    Enter your deposit

    Type the amount or drag the slider. Six-month promotional CDs sometimes require a higher minimum than the standard tier — check before you assume the rate applies.

  2. 2

    Use the 6-month rate specifically

    Banks price each term separately and the six-month line is often the most competitive. Do not carry over the rate from a different term.

  3. 3

    Read the interest figure

    You receive roughly half the annualised APY over six months. The interest tile shows the actual dollars rather than the annualised percentage.

  4. 4

    Test it against 12 months

    Switch the term chip to 12 and compare. If the six-month rate is higher, you are being paid to stay flexible — but only until it renews.

A $25,000 deposit in a six-month CD

Risultato

Return over the term

The 4.40% APY delivers 2.18% across six months. Savers routinely expect the full 4.40% and are disappointed at maturity — the APY is a per-year figure and the term is half a year.

Rolling a 6-month CD twice versus one 12-month CD, on $25,000

Risultato

Two 6-month terms
$26,100.00
One 12-month term

$37.50

Rolling wins by $37.50 only if the second six-month rate matches the first. If it renews 0.50% lower you finish at $26,037.43 — behind the 12-month CD. The 12-month term is buying rate certainty, and $37.50 is what that certainty costs.

Metodologia

Accuratezza e ipotesi

Ogni calcolatore parte da alcune ipotesi. Ecco le nostre, dichiarate apertamente, così sa esattamente che cosa i numeri considerano e che cosa no.
  • Six months is treated as 0.5 years. Banks count actual days, so a 181- or 184-day half-year differs marginally from the figure shown.

  • The rolling comparison holds the second-term rate constant, which is the assumption most likely to be wrong. It is shown to make the trade-off visible, not as a forecast.

  • The rate is fixed and the interest compounds inside the CD rather than being paid out.

  • The savings comparison assumes the savings rate persists. It is variable and can be reduced without notice.

Le convenzioni seguono la Regulation DD (12 CFR 1030), che disciplina il modo in cui gli istituti statunitensi comunicano l'APY sui conti di deposito. I depositi presso istituti assicurati sono protetti dalla FDIC fino a $250,000 per depositante, per banca e per categoria di titolarità.

Dettagli

Dettagli e regole principali

Informazioni rapide da conoscere prima di aprire o rinnovare un CD.
  • Six months is where promotional pricing concentrates. If one term on a bank's sheet is materially above the others, it is frequently this one — and it usually reverts to a standard rate on renewal.

  • A 90-day interest penalty on a six-month CD costs roughly half the term's interest. On $25,000 at 4.40% that is about $271 against $544 earned, so an early withdrawal at the halfway point still leaves you ahead of zero — unlike a 3-month CD.

  • The APY is annualised regardless of term length. Regulation DD requires it, which is what makes a six-month CD comparable with a five-year one, but it is also why the interest looks smaller than savers expect.

  • A six-month CD renews twice a year, so you face the reinvestment decision twice as often as on a one-year term. On an inverted curve that is an advantage; when rates are falling it is the main risk.

  • Pairing a six-month CD with a longer one is the simplest form of laddering — half the money stays liquid within six months, half captures the longer rate.

Applicazioni

A chi serve questo calcolatore

  • Savers who want yield without a long lock

    Six months is the shortest term that reliably carries a competitive rate. It is the default answer for money you will not need immediately but do not want to commit for a year.

  • Anyone expecting rates to move

    If you think rates are near a peak, six months lets you capture today's rate and reassess before the year is out. If you think they are near a floor, the twelve-month term is the safer choice.

  • First-time CD buyers

    Half a year is long enough to be worth doing and short enough that a mistake is cheap. Most people's first CD should probably be this one.

  • At 4.40% APY, $217.63 — maturing at $10,217.63. The APY is an annual figure, so a six-month term returns about half of it: 2.18% of the deposit rather than 4.40%.
