What is the difference between CD yield and CD rate?

The rate is the input the bank applies to your balance; the yield is the output you receive once compounding and the term have done their work. On a one-year CD compounding daily, a 4.10% rate produces a 4.185% yield. Regulation DD requires banks to advertise the APY precisely so savers compare yields rather than rates.

What is a good CD yield?

A competitive CD yield tracks short-term Treasury yields, because that is the bank's alternative source of funds. If the best CD you can find pays materially less than a Treasury bill of the same maturity, the bank is not competing for your deposit and it is worth looking elsewhere.

How is CD yield taxed?

As ordinary income, at your full marginal rate, in the year the interest is credited — reported on Form 1099-INT when it exceeds $10. There is no preferential rate as there is for qualified dividends or long-term capital gains, which is why the after-tax yield sits so far below the headline.

Does a higher yield always mean a better CD?

No. A higher yield paired with a longer term means you are locked in longer, and one paired with a harsher early withdrawal penalty means less flexibility if rates rise. Compare the yield first, then read the penalty and the renewal terms before deciding.

संक्षिप्त उत्तर

How do you calculate the yield on a CD?

A CD's yield is the interest it pays expressed as a percentage of the deposit, and there are three versions of it that get confused with one another. Total yield over the term is simply interest ÷ principal: a $50,000 CD at 4.10% for 18 months earns $3,171.34, a total yield of 6.343%. Annualised yield — the APY — restates that as a per-year figure so terms of different lengths can be compared, here 4.185%. After-tax yield subtracts what you owe, and for most savers it is the only one that describes reality: at a 24% marginal rate the same CD keeps $2,410.22, an after-tax APY of roughly 3.181%. The reason the distinction matters is that CD interest is taxed as ordinary income at your full marginal rate in the year it is credited, not at the long-term capital gains rate, so the headline yield on a CD is further from the yield you keep than on almost any other saving instrument.

फ़ॉर्मूला और तरीक़ा

गणना कैसे होती है

Yield = (A − P) / P

Total yield over the term. Annualising it gives the APY: (A/P)^(1/t) − 1.

A: Maturity value at the end of the term
P: Principal — your opening deposit
t: Term in years, used to annualise
APY: Annualised yield — the per-year rate the term-yield implies
τ: Your marginal tax rate; after-tax yield ≈ APY × (1 − τ)

चरण दर चरण

1
Compute the maturity value A with A = P(1 + r/n)^(nt).
2
Subtract the principal to get the interest the CD paid.
3
Divide by the principal. That is the total yield across the whole term.
4
Raise (A/P) to the power 1/t and subtract 1 to annualise it into an APY.
5
Multiply the APY by (1 − your marginal tax rate) for the after-tax yield.

इस कैलकुलेटर का उपयोग कैसे करें

चार इनपुट, तुरंत नतीजे। न कुछ सबमिट करना है, न कहीं साइनअप करना है।

1
Enter your deposit and rate
Type the amount and the rate from the bank's rate sheet, setting the toggle to match whether they quoted an APY or a nominal APR.
2
Set the exact term
Yield is only comparable once it is annualised, and annualising needs the true term. A 13-month promotional CD is not a one-year CD.
3
Read the effective APY
The effective APY tile is the annualised yield. This is the figure to carry across to any other offer, whatever term it runs for.
4
Apply your tax rate
Multiply the APY by one minus your marginal rate. Compare that against a Treasury or municipal alternative, which are taxed differently.

हल किए गए उदाहरण

असली आँकड़े, पूरी तरह हल किए गए — ताकि आप अपने आँकड़ों से कैलकुलेटर को परख सकें।

An 18-month CD, shown as term yield, annual yield and after-tax yield

Deposit: $50,000
Rate: 4.10% nominal, compounded daily
Term: 18 months
Marginal tax rate: 24%

Interest earned: $3,171.34
Total yield over the term: 6.343%
Annualised yield (APY): 4.185%
After-tax yield: ≈ 3.181%

The three figures describe the same CD and differ by more than three percentage points. Quoting the 6.343% makes the CD look better than a one-year account paying 4.30%; annualising shows it is slightly worse. Always compare annualised.

Two offers on different terms, made comparable by annualising

Offer A: $50,000, 7-month promo at 4.60% APY
Offer B: $50,000, 18-month at 4.10% nominal

Offer A — interest: $1,329.08
Offer A — annualised yield: 4.600%
Offer B — interest: $3,171.34
Offer B — annualised yield: 4.185%

Offer B pays more than twice the dollars, and is the worse rate. That is the whole reason annualised yield exists. Offer A wins on yield but leaves you re-investing after seven months at whatever rate exists then — the trade-off the annualised figure cannot show you.

सटीकता और मान्यताएँ

हर कैलकुलेटर कुछ मान्यताएँ रखता है। हमारी मान्यताएँ यहाँ साफ़-साफ़ दी गई हैं, ताकि आपको ठीक-ठीक पता रहे कि ये आँकड़े क्या शामिल करते हैं और क्या नहीं।

The after-tax figure applies a single flat marginal rate to all the interest. Real returns straddle brackets, and state income tax is on top of federal.
Yield is calculated on the opening deposit. If you add to the CD, or if the bank pays interest out rather than compounding it, the yield on your average balance differs.
The rate is fixed and the CD is held to maturity. An early withdrawal penalty can push the realised yield below zero on a short holding period.
No fee is assumed. Maintenance fees on a CD are rare but not extinct, and they come straight off the yield.

मुख्य जानकारी और नियम

CD खोलने या नवीनीकरण से पहले जान लेने लायक़ बातें, एक नज़र में।

Yield and rate are not synonyms. The rate is what the bank applies; the yield is what you end up with after compounding, term length and — if you count it — tax.
CD interest is taxed as ordinary income in the year it is credited, reported on Form 1099-INT. On a multi-year CD you owe tax annually even though you cannot touch the money until maturity, which is a genuine cash-flow consideration on long terms.
Comparing a CD against a Treasury bill needs the tax treatment included. T-bill interest is exempt from state and local income tax, so in a high-tax state a Treasury yielding slightly less than a CD can keep more.
"High-yield CD" is a marketing phrase with no regulatory definition. It usually signals an online bank with no branch network, which is a real cost advantage — but check the minimum deposit and whether the rate is promotional.
Credit unions call the payout a dividend rather than interest and quote a dividend rate alongside an APY. The APY is calculated the same way and remains the figure to compare.

आपस में कैसे जुड़े हैं

यह कैलकुलेटर किसके लिए है

Savers comparing terms that do not match
A 7-month promo against an 18-month standard cannot be judged on interest earned. Annualise both here and the ranking often flips.
Anyone in a higher tax bracket
At a 32% or 37% marginal rate the after-tax gap between a CD and a municipal bond fund narrows sharply. Knowing your after-tax yield is what makes that comparison honest.
Retirees living on interest
Income planning runs on the yield you keep, not the yield advertised. Work from the after-tax figure and the monthly interest line when you build the budget.
