CD ladder vs bullet vs barbell — which is best in 2027?
A CD ladder splits your money equally across several maturities (typically 1, 2, 3, 4, and 5 years). Every year one CD matures, giving you liquidity to spend or reinvest. A bullet puts all the money in a single maturity that lines up with when you need the cash — like one 5-year CD when funding a future down payment. A barbell splits money between very short CDs (3-12 months) and very long CDs (5-10 years), skipping the middle of the curve.
In 2027, the Treasury yield curve has been normalizing back to an upward slope after the 2023-24 inversion. Top brokered CDs from Marcus, Synchrony, Discover, and Schwab Brokerage are paying 4.0-5.0% APY across the 1-5 year range. The right strategy depends on (1) the curve's shape, (2) your liquidity needs, and (3) your view on future rates.
Strategy 1: CD ladder for steady cash flow
A ladder is the default recommendation for emergency funds and unrestricted savings because it balances three risks: reinvestment risk (rates fall), liquidity risk (need cash), and opportunity cost (rates rise after you lock in long). With $50,000 split into five $10,000 CDs at 1, 2, 3, 4, and 5 years, you get a blended APY around 4.4% and one CD maturing every year for liquidity.
When a CD matures, you reinvest it at the new 5-year rate, extending the ladder. This dollar-cost-averages your interest rate exposure across the curve over time — you never wake up to find your entire savings locked at a now-uncompetitive rate.
Strategy 2: Bullet for a specific future expense
Bullets work best when you know exactly when you need the money. Saving for a house down payment in 2030? Put it all in one 5-year CD maturing then. This captures the highest single rate on the curve (~4.8% in 2027) with zero ambiguity. The catch: zero liquidity until maturity, and early withdrawal costs 6-12 months of interest.
Bullets also work in an inverted curve where short rates are higher than long. In that case, a 6-month bullet at 5.0% beats locking in 4.0% for 5 years — assuming you can keep rolling at similar short rates.
Strategy 3: Barbell to hedge both ends
A barbell (50% in 1-year, 50% in 5-year) gives you liquidity in 12 months plus a long-rate lock-in. Its blended APY (~4.4% in a normal curve) often matches the ladder, but the rebalancing is simpler — only two CD positions to manage. The drawback: when the 1-year matures, you're fully exposed to whatever 1-year rates are at that moment.
How to use this calculator: enter your investment amount, pick a yield curve shape (or enter custom 1y/2y/3y/5y rates from your bank's website), and the tool shows blended APY and 5-year total interest for all three strategies. Use this to choose the right approach for your specific time horizon and liquidity needs.
