CD Ladder Calculator

A CD ladder splits your money across CDs of different lengths, so cash frees up regularly while most of it earns long-term rates. Enter your amount and rates to see your ladder.

How a CD ladder works

Split $20,000 into five $4,000 CDs maturing in 1, 2, 3, 4, and 5 years. Every year a rung matures: spend it if needed, or roll it into a new 5-year CD at the top of the ladder. After the first cycle, every dollar earns 5-year rates while a rung still matures every single year.

Liquidity of a 1-year CD + (eventually) the rate of a 5-year CD

Why ladder instead of one CD

  • Rate-risk insurance both directions: if rates rise, next year's maturing rung catches the new rates; if they fall, most of the money is already locked in high.
  • No big early-withdrawal penalty risk: needing cash means waiting months for the next rung, not breaking a 5-year CD (penalties typically eat 3–12 months of interest).
  • Inverted-curve note: when short CDs pay more than long ones (as in the default numbers), ladders lose some appeal versus rolling short CDs — but the ladder still hedges reinvestment risk when short rates eventually drop.

Where ladders fit

Money needed in 1–5 years with zero risk tolerance: house down payment, planned tuition, a known big expense. Not for emergency funds (not liquid enough — use high-yield savings) and not for 20-year money (stocks historically beat CD rates by a wide margin).

Frequently asked questions

What is a CD ladder?

Splitting savings across CDs of staggered maturities (e.g., 1–5 years). One matures every year for spending or reinvestment at the long end, combining regular access with long-term rates.

Is a CD ladder worth it?

For safe money needed over the next 1–5 years, usually yes — it hedges rate moves in both directions. When short-term rates exceed long-term (inverted curve), simply rolling 1-year CDs can compete.

What happens when a CD matures?

A short grace window (usually 7–10 days) to withdraw or move it; otherwise most banks auto-renew at the current rate. Calendar the maturity dates — auto-renewal rates are often poor.

Are CDs safe?

US bank CDs carry FDIC insurance up to $250,000 per depositor per bank (NCUA at credit unions). The risk is not loss but lock-up: early withdrawal costs months of interest.
