A CD ladder splits your money across multiple CDs with staggered maturity dates — typically 1, 2, 3, 4, and 5 years. Every year one CD matures and you can reinvest at then-current rates, or use the cash. You get the higher rates of longer-term CDs combined with annual access to one rung.

How much money should I put in a CD ladder?

Money you don't need for 1+ years but want guaranteed returns on. Typical use case: $20K-$200K of medium-term savings (down payment in 3-5 years, retirement bucket beyond emergency fund). Anything you might need within 12 months belongs in HYSA, not CD.

Is a CD ladder better than a single 5-year CD?

Ladder usually wins on flexibility. Single 5-year CD has a marginally higher rate (~0.2-0.4% more) but locks 100% of your money for 5 years. Ladder gives you 20% liquidity every year while still capturing most of the long-term rate after year 5 (every rung becomes a 5-year CD).

What if interest rates rise during my ladder?

You benefit: each year a rung matures, you reinvest at the new higher rate. After 5 years, all rungs are at the new rate. A single long CD would have you locked in at the old (lower) rate.

What if interest rates fall during my ladder?

You're partially protected: rungs already in place keep their original rates until maturity. New money rolling in gets the new lower rate, but the average yield drops gradually rather than dropping all at once.

Can I build a CD ladder at one bank or do I need multiple?

Same bank works fine if amounts stay under the $250K FDIC limit per depositor per bank. Many use 2-3 banks to chase best rate per term — Marcus often best on 1-2 yr, BMO Alto or Bask on 5 yr. The tracking overhead is real; some prefer one bank for simplicity.

What's the minimum to start a CD ladder?

Some online banks (Ally, Marcus) have no minimums per CD, so you could ladder $1,000 across $200 rungs. Practically, $5,000 minimum total ($1,000/rung) makes the math worthwhile — below that the absolute dollars saved vs HYSA are small.

How a CD ladder works

Year 0: split your money into 5 equal parts. Buy 1-year, 2-year, 3-year, 4-year, and 5-year CDs.
Year 1: the 1-year CD matures. Reinvest the principal + interest into a new 5-year CD at then-current rates (or take the cash if you need it).
Year 2: the 2-year CD matures. Reinvest into a new 5-year CD.
Years 3-5: same pattern. Each year one CD matures and you reinvest into a new 5-year.
Steady state (Year 5+): every CD is now a 5-year CD, and you have one maturing every year. You earn the (highest) 5-year rate with 20% liquidity every year.

CD ladder vs single long CD vs HYSA

Strategy	Yield ($50K example)	Liquidity	Best when
5-rung CD ladder	4.37% blended	20%/year	Unsure about rates, want flexibility
Single 5-year CD	4.10%	Locked 5 yrs	Convinced rates will fall
HYSA only	~4.50% (variable)	Daily	Need full liquidity or expect rates to rise
50/50 ladder + HYSA	~4.44%	~60%/year	Balanced default for most people

When NOT to build a CD ladder

If you have high-interest debt (credit cards 18%+). Paying that off is a guaranteed 18%+ return — beats any CD ladder.
If your time horizon is 10+ years. Index funds historically return ~7% real, ~10% nominal — CD ladders top out around 4-5%.
If you might need the money in <1 year. Use HYSA — no penalty, similar APY.
If your balance is over $250K at one bank. Either split across banks or use Treasury Direct for federally-backed T-Bills with unlimited coverage.

Tax note

CD interest is taxed as ordinary income in the year earned (federal + state, no preferential treatment). On a $50K ladder yielding ~$2,250/yr at a 22% federal bracket plus 5% state, your after-tax yield is ~3.27%. T-Bills are state-tax-free, which often makes them a better choice in high-state-tax states (CA, NY, NJ) — see the comparison in our best HYSA rates guide.

Plug your own numbers

Interest projections assume simple interest over the CD term (most CDs credit at maturity). Daily-compounded CDs yield marginally more than shown. APYs change weekly; verify at your chosen bank's site before opening.
