简短回答

How much does a 5-year CD earn?

A 5-year CD is the longest term most banks offer as standard, and it exists to sell one thing: a rate you cannot lose for half a decade. A $25,000 deposit at 3.80% APY earns $5,124.98 and matures at $30,124.98; $100,000 matures at $120,499.92. Over five years compounding contributes $374.98 more than simple interest would have, so the effect is finally material rather than decorative. Two considerations dominate the decision. Rolling one-year CDs at today's 4.25% would produce $30,783.67 — $658.69 ahead — so on current pricing you are paying to lock in, not being paid to. And the early withdrawal penalty at this term is typically a full 365 days of interest, $950.00 on $25,000, which means an exit in the first two years hands back most of what you earned. Take the five-year term when you are confident about both the money and your view on rates.

公式与方法

计算方式

A = P(1 + r/n)^(nt), t = 5

Five years of compounding. At 3.80% on $25,000 it adds $374.98 over what simple interest would have paid.

A
Maturity value after 60 months
P
Opening deposit
r
Nominal annual rate as a decimal
n
Compounding periods per year (daily = 365)
t
5 — the term in years

分步说明

  1. 1

    Convert the 60-month rate to a decimal and divide by n.

  2. 2

    Raise (1 + r/n) to the power n × 5.

  3. 3

    Multiply by the deposit for the maturity value.

  4. 4

    Subtract the deposit for the total interest across five years.

  5. 5

    Multiply the deposit by the rate to approximate a 365-day early withdrawal penalty.

使用指南

如何使用本计算器

输入四项参数,结果实时呈现。无需提交,也无需注册。
  1. 1

    Enter your deposit

    Type the amount or drag the slider. Five years of interest is enough to push a large deposit past the $250,000 insurance limit — check the maturity value against it.

  2. 2

    Enter the 60-month rate

    Use the rate quoted for the five-year term. On an inverted curve it will usually be below the one-year rate; that is expected, not an error.

  3. 3

    Read the growth chart

    Five years is the first term where the curve visibly bends away from a straight line. That bend is the compounding you are buying.

  4. 4

    Price the exit before you commit

    Multiply the deposit by the rate for an approximate 365-day penalty. If that number would be unsurvivable, the term is too long for this money.

示例

A $25,000 deposit in a 60-month CD

输入项

Deposit
$25,000
Rate
3.80% APY
Term
60 months

结果

Total interest
$5,124.98
Maturity value
$30,124.98
Simple interest would have paid
$4,750.00
Contributed by compounding
$374.98

Compounding adds $374.98 across five years — about 7.9% more interest than a simple-interest account at the same rate. This is the term where the effect stops being a rounding difference.

Breaking the same CD at month 24 with a 365-day interest penalty

输入项

Deposit
$25,000
Rate
3.80% APY
Withdrawn
Month 24 of 60
Penalty
365 days of interest

结果

Interest earned by month 24
$1,936.10
Penalty charged
$950.00
Net proceeds
$25,986.10
Effective annual return
≈ 1.95%

Two years in, the penalty takes nearly half the interest and cuts the realised return to about 1.95% a year — below what a savings account would have paid with no lock-up at all. The penalty does not just cost money; it retroactively makes the whole decision wrong.

方法论

精确度与假设条件

每一个计算器都有其假设前提。以下是我们的假设,明确列出,让你清楚知道这些数字涵盖了什么、又没有涵盖什么。
  • The rate is fixed for all sixty months and interest compounds inside the CD.

  • The penalty example uses a 365-day interest convention, which is the most common at five years. Some institutions charge 540 days on terms this long — check the disclosure.

  • The rolling comparison holds the one-year rate at 4.25% for five consecutive years, which is a scenario for contrast rather than a prediction.

  • Figures are gross of tax and of inflation. At 2.5% inflation, a 3.80% nominal return is roughly 1.27% in real terms.

细节

关键细节与规则

在开立或续存 CD 之前值得快速浏览的要点。
  • Five years is the standard maximum term. Beyond it, availability thins sharply and the rate premium usually disappears entirely — which is why a ten-year CD is a specialist product rather than a longer version of this one.

  • The penalty at this term is typically a full year of interest, $950.00 on $25,000 at 3.80%. Federal rules allow the shortfall to come from principal if the CD has not earned that much yet, so an exit inside year one returns less than you deposited.

  • Interest is taxed annually as ordinary income. Five years produces five 1099-INT forms and five tax bills on money you cannot access without triggering the penalty.

  • A five-rung ladder using 1, 2, 3, 4 and 5-year CDs earns close to the five-year rate on average while freeing a fifth of the money every twelve months. For most savers it is the better version of this decision.

  • No-penalty CDs exist but pay materially less. If there is real doubt about the horizon, the lower rate on a no-penalty product is usually cheaper than the penalty risk on this one.

适用场景

本计算器适合哪些人

  • Savers who want a rate they cannot lose

    If your view is that rates fall from here, five years at today's level is the trade that expresses it — and the $658.69 you appear to give up against rolling is the premium on that insurance.

  • Retirees building predictable income

    A known figure on a known date, insured to $250,000, with no market risk. For the stable sleeve of a retirement plan the five-year CD does a job no fund can quite replicate.

  • Anyone tempted by the headline

    Read the penalty example before committing. Five years is a long time, and the term punishes changed circumstances harder than any other standard CD.
