Financial Readiness
Three safe places to park cash. The right one depends on when you need the money.

Savings accounts, money market accounts, and CDs are all insured deposit accounts. They keep your money safe and pay interest. What differs is how fast you can reach the cash and how much rate you earn. The rate is shown as APY, which is the annual percentage yield, or what you earn in a year.
Quick read: use savings for everyday flexibility, a money market for a bit more rate with limited transactions, and a CD when you can lock a fixed rate on money you can leave alone. Many people use more than one at the same time.
All three are safe. The choice comes down to access and rate. Pick the one that matches how soon you need the cash.
Match it to your timeline
Same safety. Different access and rate.

A savings account is a basic deposit account that earns interest and lets you add or take out money. It is the flexible option, well suited to an emergency fund or a short-term goal where access matters most. A high-yield version pays a higher APY. A money market account is also a deposit account at a bank or credit union. It tends to pay a bit more than basic savings, but it usually limits how many transactions you can make by check, debit card, or electronic transfer, and it may ask for a higher minimum balance. A CD, or certificate of deposit, is a time deposit: you agree to leave a set amount for a fixed term, from a few months to several years, in exchange for a fixed rate.
Same safety, different access and rate. Savings gives you the easiest access and a variable APY, which is a strong fit for an emergency fund. A money market often pays a higher APY than basic savings, but it limits some transactions and may need a higher minimum. A CD locks your money for the term at a fixed rate, and taking it out early usually means an early-withdrawal penalty. All three are insured up to $250,000 per depositor, per institution, per ownership category, at an FDIC bank or NCUA credit union. One caution: do not confuse a money market deposit account with a money market mutual fund. The fund is an investment product, not a deposit, so deposit insurance does not cover it.
Savings and money market APYs are variable, so they can change over time. A CD rate is fixed for the term, which is the trade-off for locking the money up. One more thing worth knowing: the old federal six-per-month limit on savings transfers ended in 2020. Your bank or credit union can still set its own limits, so read the account agreement before you assume.
All three are insured the same way, so safety is not the deciding factor. The question is which tool fits the job, so the money is ready when your timeline says you need it.

Right tool, right job
Keep the emergency fund liquid, not locked in a CD.

You do not have to sort this out alone. Every active-duty, Guard, and reserve member, and their family, can get free financial counseling. Sit down with your installation Personal Financial Manager or Counselor, in person and on base, or reach a counselor through Military OneSource. The DoD Office of Financial Readiness has free military money education and tools. For plain-language answers on accounts, rates, and borrowing, the CFPB runs Ask CFPB, and the FDIC Consumer Resource Center explains how deposit accounts and insurance work.

Are all three FDIC insured?
Yes. At an FDIC bank, up to the limits. At a credit union, the NCUA gives comparable coverage. Either way, you are insured up to $250,000 per depositor, per institution, per ownership category.
Which pays the most?
It depends on the institution and the moment. CDs often pay a fixed rate above basic savings in exchange for locking the money up, and money market accounts can pay more than basic savings. Compare them by APY.
Can I lose money?
Insured principal is protected within the limits. The main things to watch are early-withdrawal penalties on CDs and inflation outpacing your APY over time.
