How do you calculate APR on a CD?

APR = n × ((1 + APY)^(1/n) − 1), where APY is the quoted yield as a decimal and n is the number of compounding periods per year. It converts an effective annual yield back into the nominal rate that is actually applied at each compounding period. A 4.60% APY compounded daily corresponds to a 4.50% APR. You need this conversion whenever a bank hands you an APY but a calculator, a spreadsheet or a comparison expects a nominal rate — entering an APY where a nominal rate belongs applies compounding a second time and overstates the result. APR is always the lower of the two figures on any account compounding more than once a year, and the gap widens as the rate and the compounding frequency rise. It is the rate the bank works with internally; APY is the rate it advertises.

Which is higher on a CD, APR or APY?

APY is higher on any CD that compounds more than once a year, and the two are identical only when interest compounds exactly annually. The reason is that APY includes the effect of interest earning interest, while APR is the plain nominal rate applied at each compounding period. A 4.40% APR compounded daily produces a 4.50% APY — a gap of ten basis points that widens as either the rate or the compounding frequency increases. On a $10,000 deposit that difference is worth about $10 over a year, which sounds trivial until you compare two offers where one is quoted as APR and the other as APY and assume they are equivalent. They are not. Regulation DD requires US institutions to disclose APY precisely so that offers can be compared on a single consistent number.

Why do banks advertise APY instead of APR on CDs?

Two reasons, and only one of them is marketing. Regulation DD, the Truth in Savings rule at 12 CFR Part 1030, requires US institutions to disclose APY on deposit accounts, so it is a legal obligation rather than a choice. The reason the rule exists is that APY is genuinely the more useful figure: it folds compounding frequency into one number, so a CD paying 4.40% compounded daily and one paying 4.50% compounded annually can be compared directly — they are both 4.50% APY and identical for a saver. The marketing benefit is real too, since APY is always the higher of the two figures on an account compounding more than once a year. On $10,000 over a year the difference is around $10, so the advertising advantage is smaller than the comparability benefit.

Jawaban singkatnya

Bagaimana cara menghitung APR pada CD?

A CD's APR is its nominal annual rate before compounding — the rate actually applied at each compounding period — and it converts from APY as APR = n × ((1 + APY)^(1/n) − 1). A 4.60% APY compounded daily corresponds to a 4.50% APR. You need this conversion whenever a bank quotes you a nominal or "interest rate" figure rather than APY, because entering a nominal rate into a calculator expecting APY applies compounding twice and overstates your return. It also matters when comparing a CD against a product quoted in APR, such as a loan you might otherwise pay down. APR is always the lower of the two numbers on any account compounding more than once a year, which is why marketing leads with APY, and why Regulation DD makes APY the required disclosure.

Rumus & metode

Cara menghitungnya

APR = n × ((1 + APY)^(1/n) − 1)

Strips the compounding effect back out of an advertised yield.

APR: Nominal annual rate, before compounding
APY: Advertised annual percentage yield, as a decimal
n: Compounding periods per year

Langkah demi langkah

1
Convert the advertised APY to a decimal (4.60% → 0.046).
2
Add 1 to get the annual growth factor.
3
Take the n-th root — raise it to the power of 1 ÷ n.
4
Subtract 1 to get the rate for a single compounding period.
5
Multiply by n and by 100 for the annualised nominal rate.

Panduan

Cara memakai kalkulator ini

Empat input, hasil langsung. Tidak ada yang perlu dikirim dan tidak perlu mendaftar.

1
Enter the advertised rate
Type the bank's quoted figure and set the toggle to APY, which is how deposit rates are normally published.
2
Match the compounding frequency
This drives the conversion. Daily compounding creates the largest gap between APY and APR.
3
Read both rates
The result card shows APY and APR together, so you can see precisely what compounding contributes.

Converting a 4.60% APY quote on a daily-compounding CD

Advertised: 4.60% APY
Compounding: Daily (n = 365)

Nominal APR: 4.50%
Contributed by compounding: 0.10 pts

The bank credits interest at a 4.50% annual rate; daily compounding is what lifts the effective yield to 4.60%.

APR here means the nominal deposit rate. On loans, APR also includes fees — that is a different calculation entirely.
The conversion assumes interest compounds at the stated frequency and stays in the account.
A 365-day year is used, consistent with Regulation DD.

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

Detail dan aturan penting

Fakta ringkas yang perlu diketahui sebelum Anda membuka atau memperpanjang CD.

For deposits, APY > APR whenever interest compounds more than once a year. For loans the relationship is reversed in effect, because fees inflate loan APR.
If a bank quotes only an 'interest rate' with no APY label, treat it as the nominal APR and convert before comparing.
The APY–APR gap scales with the rate: about 0.01 points at 1%, roughly 0.13 points at 5%.
If your CD pays interest out monthly rather than compounding it, your realised return matches the APR, not the APY.
