How to build a CD ladder in 5 steps.
Last verified July 7, 2026The direct answer. Divide your cash into equal parts and buy CDs maturing at staggered dates, one year apart for a classic five-year ladder. From then on, one CD matures every year; roll each one into a new five-year CD and soon every dollar earns the longest, typically highest, rate while a rung still comes due every twelve months. The ladder suits money you want beyond an emergency fund, with a known schedule and FDIC insurance. Set maturity reminders, because banks auto-renew silently.
Decide how much belongs in the ladder.
Ladder money is cash you can schedule: a house fund three years out, retirement cash reserves, proceeds waiting for a plan. Keep the emergency fund out; a properly built ladder still charges early-withdrawal penalties on any rung you break. $10,000 makes a clean five-rung ladder at $2,000 a rung, and most banks open CDs from $500.
Pick the structure to match your horizon.
The classic build is five equal rungs at one, two, three, four, and five years. A shorter ladder of 3, 6, 9, and 12 months fits money you may want within two years. Compare rates across online banks and credit unions before buying; the spread between an average and a top rate on the same term often exceeds half a percent.
Buy every rung on the same day.
Open all the CDs at once so the maturity schedule stays clean: one rung per interval, no gaps and no bunching. At an online bank the whole purchase runs in under an hour from a linked account. Note each CD's rate, maturity date, and early-withdrawal penalty in a simple tracking sheet.
Roll each maturing rung into a new longest CD.
When the one-year CD matures, reinvest it into a new five-year at that day's best rate. Repeat every year, and by year five all rungs are five-year CDs earning long-term rates while one still matures annually. Any maturity you need in cash simply exits the ladder; the rest keeps rolling.
Guard the two quiet risks: auto-renewal and FDIC limits.
Banks auto-renew maturing CDs into same-term CDs at whatever rate applies, inside a grace window of typically 7 to 10 days. Calendar every maturity two weeks ahead so each rollover is your decision at your chosen bank. Keep total deposits per bank under the $250,000 FDIC limit per depositor, and split across banks past it.
Five things to do this week.
- Separate schedulable cash from your emergency fund.
- Choose the five-year or the 12-month ladder structure.
- Compare CD rates at three online banks or credit unions.
- Open every rung the same day and log rates and maturities.
- Set calendar alerts two weeks before each maturity.
Questions readers ask most often.
What is the point of a CD ladder over one big CD?
The ladder captures long-term rates while returning a rung to cash every year. One five-year CD pays the top rate and locks everything for five years; one one-year CD stays liquid at a lower rate. The ladder takes both halves of the trade.
Are CD ladders worth it versus a high-yield savings account?
A high-yield account's rate floats with the market; a CD locks its rate for the term. Ladders win when you want today's rates guaranteed forward, and savings accounts win on pure access. Many savers run both: the emergency fund floating, the scheduled money laddered.
What happens if I need the money before a CD matures?
You break one rung and pay its early-withdrawal penalty, typically 3 to 12 months of interest, while the other rungs keep earning untouched. That isolation is a designed feature of the ladder. No-penalty CDs can serve as the shortest rung when flexibility ranks high.
Are CDs safe?
CDs at FDIC-insured banks and NCUA-insured credit unions are protected to $250,000 per depositor, per institution, per ownership category. The rate is contractual, the schedule is known, and the ladder adds diversification across time.
Brokered CDs or bank CDs for a ladder?
Bank CDs suit most ladders: simple, penalty-defined, auto-manageable. Brokered CDs from many banks sit in one brokerage account, useful for large ladders spread across issuers, and sell on a market rather than by penalty when exited early, which can return less than face value.
