How to Build a CD Ladder in 2026
Step 1: Determine your total investment amount. Popular options: $5,000, $10,000, $25,000, or $50,000. Divide by the number of rungs (usually 5 for a 5-year ladder).
Step 2: Choose your term structure. A 5-year ladder uses 1yr, 2yr, 3yr, 4yr, and 5yr CDs. A 3-year ladder uses 1yr, 2yr, and 3yr CDs. Longer terms typically offer higher rates.
Step 3: Shop for the best rates. Compare APY across online banks, credit unions, and traditional banks. Online banks typically offer 0.5-1% higher rates. Use the sponsored link above to compare rates.
Step 4: Purchase CDs. Buy each CD at different banks if needed to get the best rates. Keep each CD under $250,000 to maintain FDIC coverage.
Step 5: Reinvest maturing CDs. When each CD matures (annually), reinvest the full amount (principal + interest) into a new 5-year CD to maintain the ladder indefinitely.
