The 3-Year CD: The Middle of the Curve
Three years sits at the center of the CD curve — long enough for compounding to matter and for a locked rate to protect you through a full rate-cutting cycle, short enough that the commitment doesn't feel permanent. A $10,000 deposit at 4.30% APY grows to about $11,346 — roughly $1,346 in interest, of which about $56 is pure compounding that simple interest would never pay.

At 4.30% APY: $10,000 → about $11,346; $25,000 → about $28,366; $50,000 → about $56,731. Enter your own deposit and rate above for exact figures.
When 3 Years Is the Right Term
- Medium-term goals: a car purchase, a wedding, or a home project about three years out matches this maturity exactly — no penalty risk, maximum rate.
- Rate-cycle insurance: most rate-cutting cycles play out within 2-3 years. A 3-year lock rides through one at yesterday's rates.
- Ladder middle: the 3-year rung anchors the classic 5-rung ladder — plan yours with our CD Ladder Calculator.
Check Both Neighbors First
Rate curves aren't always smooth: sometimes the 2-year rate is nearly identical (take the shorter lock), and sometimes the 4-year rate pays a real premium (consider stretching). Penalties on 3-year CDs typically run 6-12 months of interest — check your exit cost with the Early Withdrawal Penalty Calculator before committing money you might need.
