Financial Readiness
A CD ladder gives you fixed rates and regular access, without locking up all your cash at once.

A certificate of deposit, or CD, is money you agree to leave at a bank for a set term at a fixed rate. A CD ladder splits your money across several CDs with staggered end dates, so one comes due at regular intervals while the rest stay locked at a fixed rate.
You get the higher fixed rates of longer CDs plus regular access to part of your cash. Less guesswork about rates, and fewer early-withdrawal penalties.
Instead of one big CD, split a lump sum into rungs that mature one year apart. Each year one rung comes due, and you roll it into a new long-term CD at the top of the ladder.

How it works
You are not betting everything on one rate at one moment.

A CD ladder is a set of CDs with different end dates. Instead of putting one lump sum in a single CD, you divide it into rungs that mature one after another. As each rung matures, you can spend the money or roll it into a new long-term CD at the top of the ladder.
Three reasons. Access: part of your money frees up at regular intervals, so you are less likely to break a CD early and pay a penalty. Rate protection: if rates rise, your next rung can capture the change; if they fall, your longer rungs hold their fixed rate. Discipline: the structure keeps money parked for dated goals, like a PCS or a vehicle, without tempting daily withdrawals.
A ladder still ties up money. If you pull from a rung before it matures, the early-withdrawal penalty applies, and federal law sets only a minimum, not a maximum, so check the terms. Ladders also take a little setup and tracking. And a CD is for money you can leave alone, so your emergency fund belongs in a liquid account like savings, not in a CD.
Here is why the timing fits military life.
A ladder lets you point each maturity at a known event, so cash arrives when you need it at a fixed rate.
Timed to your dates: Military life runs on dates: ETS, PCS windows, reenlistment, a vehicle you know you need to replace. ETS is the end of service. A ladder makes cash arrive when you need it, at a fixed rate.

How many rungs should a ladder have?
Common ladders use 3 to 5 rungs, but the right count depends on your timeline and how often you want money to free up. There is no single correct number.
What happens when a CD matures?
You can withdraw the principal and interest with no penalty, or roll it into a new CD. Review your account agreement, since many CDs renew automatically, and set a reminder before the maturity date.
Are CD rates fixed?
A standard CD rate is fixed for the term. That is the point of a ladder: you lock fixed rates across several dates.
