Jawaban singkatnya
A short-term CD of 3 to 9 months earns a pro-rated share of its annual rate through A = P(1 + r/n)^(nt), where t is the term in months divided by 12. A $10,000 deposit in a 7-month CD at 4.75% APY earns $274.40; the same $10,000 at 4.50% APY over 6 months earns $222.52. Odd terms like 4, 7 or 13 months are usually promotional — banks use them to win deposits without repricing their standard shelf — so the headline rate is often above the 12-month rate and reverts to the standard rate on renewal if you let it roll. That renewal is the thing to diary. The trade-off against a longer CD is that you keep flexibility and reinvestment optionality, and give up the certainty of holding a known rate for longer.
Rumus & metode
A = P(1 + r/n)^(n × months/12)

Convert the term to years by dividing the months by 12.
Convert the advertised rate to a decimal and divide by n.
Add 1 and raise to the power of n × years.
Multiply by the deposit for the maturity value.
Subtract the deposit for the interest earned over the short term.

Metodologi
The promotional rate applies for the full stated term.
The CD does not auto-renew at the promotional rate — renewals almost always drop to the standard rate for that term.
The deposit meets any minimum required to qualify for the promotional rate.
Konvensinya mengikuti Regulation DD (12 CFR 1030), yang mengatur cara lembaga keuangan AS mengungkapkan APY pada rekening simpanan. Simpanan di lembaga yang dijamin dilindungi FDIC hingga $250,000 per penyimpan, per bank, per kategori kepemilikan.

Detail
Odd terms such as 4, 7, 11 and 13 months are deliberate: they are promotional products designed to attract new deposits, and they often out-pay the standard 12-month CD.
Watch the renewal terms. A 7-month CD at 4.75% typically rolls into a 6-month CD at a much lower standard rate unless you act during the grace period.
Early withdrawal penalties on short CDs are smaller — usually around 3 months of interest — but they represent a larger share of the total interest.
Short CDs suit money with a known deadline; if the date is unknown, a no-penalty CD or high-yield savings account may fit better.

FAQ
A 7-month CD pays seven twelfths of a year's compounding, calculated through A = P(1 + r/n)^(nt) with t set to 7 ÷ 12. At 4.75% APY, a $10,000 deposit earns $274.40 over the term; at 4.50% APY the same deposit earns $260.09. The interest is genuinely lower than a 12-month CD would pay, but the money is free again after seven months rather than twelve, and that optionality is the point. Odd terms like this are usually promotional — banks use them to attract deposits without repricing their standard shelf — so the advertised rate is often above the 12-month rate. The thing to diary is the renewal: a promotional 7-month CD that rolls over typically reverts to the bank's standard rate for that term, which can be considerably lower.
