3-Year CD Calculator

A 3-year CD is the medium-term sweet spot — long enough to often capture the best rate of any single CD term, short enough to limit how long you're locked in.

A 3-year CD commits funds for 36 months in exchange for a fixed APY. In a normal upward-sloping yield curve, 3-year CDs pay slightly more than 1-year CDs and slightly less than 5-year — they sit in the middle. In flat or inverted curves (like much of the recent rate cycle), the 3-year rate is often comparable to or even higher than the 5-year, making it the rate-sensitive saver's preferred term.

Common uses: a planned home down payment 2–3 years out, an education-savings rung that matures the year a child enters college, a middle rung in a CD ladder, or any sum where you're confident you won't need the money for three years and want a higher rate than a savings account would pay. A $10,000 3-year CD at 4.50% APY grows to about $14,117 over the term — roughly $4,117 in compound interest.

3-Year CD: Real Return After Inflation

At 4.50% APY on a $10,000 deposit, here is what a 3-year cd's nominal interest is worth after inflation eats some of the purchasing power. Real return uses the Fisher relation: (1 + APY) / (1 + inflation) − 1.

Inflation Assumption Real Interest Nominal Interest Real Maturity Value
2.5% (long-run CPI average) $596.86 $1,411.66 $10,596.86
3.0% (recent average) $443.29 $1,411.66 $10,443.29
3.5% (above-target) $292.66 $1,411.66 $10,292.66

Real interest = inflation-adjusted purchasing-power gain. Nominal interest is the dollar amount the bank credits. See the inflation calculator to model other rates.

3-Year CD Interest After Federal Tax

CD interest is taxed as ordinary income each year. Below: net interest earned on a 3-year cd at 4.50% APY after federal income tax at common marginal brackets, for several deposit sizes. State tax (where applicable) is on top of these numbers. Holding the CD inside a traditional IRA defers this tax until withdrawal.

3-Year CD: Frequently Asked Questions

How much does a 3-year CD earn? +

A 3-year CD earns deposit × ((1 + APY)³ − 1) in compound interest. At 4.50% APY: $10,000 earns about $1,411.66, $25,000 earns $3,529.16, $50,000 earns $7,058.31, and $100,000 earns $14,116.62. At 5.00% APY: $10,000 earns about $1,576.25, $25,000 earns $3,940.63, $50,000 earns $7,881.25, and $100,000 earns $15,762.50. Compounding adds noticeably more than 3× the 1-year return because each year's interest also earns interest.

Are 3-year CD rates better than 5-year CD rates? +

Sometimes yes, sometimes no, depending on the yield curve. In a normal upward-sloping curve, 5-year CDs pay slightly more than 3-year. In flat or inverted curves (like much of 2024–2025), 3-year CDs often pay the same or even higher than 5-year ones because the market expects rates to fall. Always check current APYs at your target bank — never assume "longer = higher rate."

What is the early-withdrawal penalty on a 3-year CD? +

Most 3-year CDs charge 6 months of interest as the early-withdrawal penalty, though some banks use 9 or 12 months for terms in this range. On a $10,000 3-year CD at 4.50% APY, a 6-month penalty is roughly $225. If you withdraw very early in the term (before 6 months of interest has accrued), the penalty can reduce your principal — your withdrawal could be less than the original deposit.

Is a 3-year CD a good idea right now? +

A 3-year CD makes sense if you have a sum you're confident you won't need for at least 36 months and you want a fixed rate that's typically higher than a savings account or a 1-year CD. The risk to consider: if rates fall sharply during the 3 years, the locked-in CD rate looks even better; if they rise sharply, you're locked in below market and can't take advantage. A CD ladder mitigates this risk by spreading maturities across several years.

Should I keep a 3-year CD inside an IRA? +

IRA CDs are a common low-volatility component of a retirement portfolio. Holding a 3-year CD inside a traditional IRA defers the tax on accrued interest until you withdraw funds in retirement; inside a Roth IRA, the interest grows tax-free if Roth rules are met. The trade-off is that IRA CDs share IRA contribution limits ($7,000 / $8,600 for age 50+ in 2026) and IRA early-withdrawal rules apply on top of the CD's own early-withdrawal penalty. Most large savers use IRA CDs for the retirement-side of a barbell, with non-IRA CDs for medium-term goals.
