What $40,000 earns in savings accounts, money markets, and CDs now

How the same $40,000 pays very different returns

A $40,000 balance can generate just $152 a year in a 0.38% savings account or about $228 in a 0.57% money market account, while a top high-yield savings account at 4.21% APY can produce about $1,684. The spread is the whole story here: safe cash is not one product, it is a set of tradeoffs between access, rate certainty and yield.

Average rates still lag inflation

FDIC national data as of April 20 show average savings at 0.38% APY, money market accounts at 0.57%, and short CDs at 0.96% for one month, 2.00% for three months and 2.19% for six months on the rate-cap-adjusted scale. Bankrate’s late-April surveys land in the same low-yield zone, with a 0.59% average savings yield and a 0.43% average money market yield, which is why the exact winner can change depending on the bank, the balance tier and the product design. On a $40,000 deposit, Bankrate’s averages translate into about $236 a year in savings and $172 a year in a money market account, still well below the Bureau of Labor Statistics’ 3.3% inflation reading for the 12 months ending March 2026.

That gap matters because sub-1% deposit yields are not just modest, they are losing purchasing power in real terms. Even if the balance is insured, the return may not keep pace with day-to-day price increases, so a saver looking only at the headline APY can miss the bigger question: what is the money actually doing after inflation?

CDs pay for patience, not flexibility

A CD makes sense when the cash has a date attached to it. The FDIC’s rate-cap-adjusted benchmarks show why shorter terms can still beat ordinary savings: a 3-month CD at 2.00% APY earns about $199 over the term on $40,000, and a 6-month CD at 2.19% APY earns about $436 over six months. A 1-month CD at 0.96% APY is still only about $32 for the month, but the rate is locked, which is the main attraction when you want certainty instead of a moving target.

That certainty comes with strings attached. CD rates are typically fixed for the term, while savings and money market rates can change more quickly, and if money has to come out early, banks can charge an early withdrawal penalty. Federal guidance says those penalties can apply when a CD is redeemed before maturity, so a CD works best only when the cash can truly sit untouched until the end date.

The best online accounts still separate themselves from the average

If you are willing to shop beyond national averages, the yield difference becomes much more dramatic. Bankrate says the best high-yield savings accounts are paying around 4% APY, and its top savings rate in late April is 4.21% from Axos Bank. On $40,000, that is about $1,684 a year, which is why online savings accounts can look more like a short-term parking place than a traditional bank account.

Bankrate’s CD survey points in the same direction. It says the best CDs are still around 4% APY, with top offers above 4%, so the strongest CD yields are close to the best savings rates on a gross basis. The difference is that a high-yield savings account leaves your money available, while a CD asks you to trade some liquidity for a fixed return. That tradeoff can be useful if you know the money will not be needed until a tuition bill, tax payment or house closing.

Safety is the same, but the strategy is not

FDIC insurance covers savings accounts, money market deposit accounts and CDs at FDIC-insured banks, up to $250,000 per depositor, per insured bank, per ownership category. A $40,000 balance sits comfortably inside that limit, so the real decision is not whether the money is safe, but how much access you need and how long you can leave the funds in place.

That is why the “best” account changes with the goal. If you need ready access, a savings account or money market account usually wins because the money stays liquid, even if the rate is middling. If the date is known and the money can stay put, a CD can beat average savings by a wide margin. If you want the highest blend of yield and flexibility, a top high-yield savings account is still the most practical middle ground, especially when average deposit rates remain far below inflation.

In short, $40,000 can earn almost nothing by current standards or something meaningful, depending on where it sits. The right choice comes down to three questions: when will the cash be needed, how much rate certainty matters, and whether the balance stays inside FDIC limits. The account with the highest headline yield is not always the best home for short-term money, but the account that matches the timeline can make a real difference.
