Checking, savings, money market or a certificate: which account does what?
Every account is a place to keep money. They differ on three things: whether you can take the money out whenever you want, whether it pays interest, and whether you can spend from it directly. As a rule, the less access you need, the more you earn. Rewards checking is the one exception.
What is the trade-off between access and earnings?
Think of two scales. One is access: how many steps stand between the money and spending it. The other is what the money earns. Institutions pay for distance. Money you can spend with a card earns little. Money locked for a term earns the most.
| Account | Spending the money | Interest it earns | What it costs you |
|---|---|---|---|
| Spend it directly | |||
| Checking | Debit card, checks, bill pay and ATM | Little or nothing | The interest you give up |
| Rewards checking | Debit card, checks and bill pay; using the card is how you qualify | Can be among the highest rates an institution posts | A capped balance and monthly rules |
| Money market | Checks or a debit card at many, capped each month | More as the balance grows | A bigger balance to earn more |
| Move it to checking first | |||
| Savings | Transfer to checking, then spend | A modest rate | No card or checks |
| High-yield savings | Transfer to checking, often from another institution, which can take a business day or more | Often several times a standard savings rate | Usually online-only access, often conditions |
| Locked for a term | |||
| No-penalty certificate | Locked for the first days, then you can close it and take the whole balance | A little below a standard certificate | A short first lock, and usually all or nothing |
| Certificate (CD) | Locked until the term ends, or pay a penalty | Usually the highest fixed rate | The full term, or a penalty to leave early |
A credit union calls its certificate a share certificate. The product is the same.
What does each account ask of you?
Checking: day-to-day money
Money comes in by direct deposit, deposits and transfers, and goes out by debit card, checks, bill pay, ATM and transfers. It pays little or nothing. Where a monthly fee applies, it is usually waived for keeping a minimum balance or receiving a regular direct deposit.
Rewards checking: everyday money that also earns
The rate pays for your banking habits, every month. The usual requirements are a minimum number of debit card purchases, online banking with e-statements, and often a direct deposit. The top rate applies only up to a balance cap, with a much lower rate above it. Miss one requirement in a month and the whole balance can earn close to nothing for that month.
Money market: larger balances that still need access
It sits between savings and checking. Deposits and withdrawals any time, and many come with checks or a debit card, so you can spend from it directly. It is not built for daily spending, though: institutions usually cap card and check use each month, and not every money market account has a card. The federal limit of six withdrawals a month ended in 2020; many institutions still set their own. The rate usually climbs with the balance, so the top tiers need large balances, and a small balance earns little. Expect a higher minimum to open and a monthly fee unless a minimum balance is kept. Some pay well only alongside a linked checking account.
Savings: an emergency fund and short-term goals
You move money to checking before you spend it. Some institutions limit withdrawals each month. Opening one usually takes only a small deposit. At a credit union, you first need to be eligible to join.
High-yield savings: the same job at a better rate
Many are online-only, so getting money to where you spend it can take a business day or more. The higher rate is usually bought with something: a membership tier, a monthly direct deposit, a linked checking account, money that is new to the institution, new customers only, or a balance cap above which the rate drops.
No-penalty certificate: a certificate you can leave early
A certificate, described next, with one difference: after a short lock at the start, you can close it without the usual penalty. The rate is usually a little below a standard certificate of the same term. Leaving early usually means closing it and taking the whole balance, so it cannot be dipped into like savings.
Certificate of deposit: money you will not need for a while
One deposit at opening; most do not accept additions. Taking money out before the term ends costs an early-withdrawal penalty, often a set number of days' or months' interest, and the institution has to tell you how it is worked out before you open the account. Longer terms usually pay more, though not always. The strongest rates are often specials on an unusual term, such as 13 months, sometimes for new money only. Many renew into a lower standard rate unless you act when the term ends.
How do you read a rate?
The same headline number can mean very different things, depending on how the institution applies it. Four structures are common. The examples are illustrative, with each step worked out.
| Structure | What it means | Example |
|---|---|---|
| Whole balance | Every dollar earns the stated rate | A 3.00% rate on $50,000. All $50,000 earns 3.00%: $1,500 in a year. |
| Tiered, whole balance | Your total balance decides the tier, then every dollar earns that tier's rate | A tier paying 2.50% from $50,000. A $50,000 balance lands in that tier, so all $50,000 earns 2.50%: $1,250 in a year. At $49,999, the whole balance earns the lower tier's rate. |
| Split tier | Each slice of the balance earns its own rate, so the rate you actually get is a blend that falls as the balance grows | 4.00% on the first $5,000 and 0.20% above it, on a $20,000 balance. The first $5,000 earns 4.00%: $200. The other $15,000 earns 0.20%: $30. $230 on $20,000 is about 1.15%, not 4.00%. |
| Qualified or relationship rate | The headline rate needs something from you: a checking account, a direct deposit, card purchases or a membership tier | A 5.00% rewards rate that drops to 0.01% in any month the requirements are missed, on $10,000. In a month they are met, it earns about $41. In a month they are missed, under 10 cents. |
Compare the APY, the annual percentage yield, not the interest rate. APY includes compounding, so it shows what a balance earns over a year, and federal Truth in Savings rules require institutions to state it the same way.
Why is the highest advertised rate not always the best return?
Because the conditions attached to it change what it pays. The biggest headline numbers are often introductory, capped at a small balance, or tied to monthly requirements. For most balances, the best return comes from the best whole-balance or standard-term rate, not the biggest number on the page.
How do banks, credit unions and the others differ?
| Type | Who can open an account | Branches and access | Deposit insurance | Ownership, and what it usually means for rates |
|---|---|---|---|---|
| National bank | Anyone | Branches and ATMs across the country, plus full online banking | FDIC | Shareholder-owned. Funded by a very large deposit base, so deposit rates often sit at the lower end of a local market. The offer is scale: branches almost anywhere and the widest range of products |
| Regional bank | Anyone, usually within its footprint | Branches across a region or several states, plus online banking | FDIC | Shareholder-owned. Rates and fees often sit between the national banks and the local institutions |
| Community bank | Anyone; usually serves one metro area or a few counties | A few local branches, with decisions made locally | FDIC | Often locally owned. Competes on relationships and local knowledge, and will pay up for deposits when it wants to fund local lending, which is why one sometimes tops a rate table its size would not predict |
| Credit union | Those eligible to join, known as the field of membership | Its own branches, plus shared branching and ATM networks used by many credit unions | NCUA, at federally insured credit unions | Member-owned and not-for-profit. Earnings go back to members as better deposit rates, lower loan rates and lower fees, which is why credit unions often lead local rate tables |
| Online-only bank | Anyone | No branches. App and web, usually with an ATM network or ATM fee refunds. Depositing cash can be hard | FDIC, under its own bank charter | Shareholder-owned. With no branches to pay for, it competes on rates and fees, and often posts some of the highest savings and certificate rates |
| Banking app | Anyone | No branches. App-first, usually built around fee-free checking and budgeting tools | Only once the money is deposited at an insured partner bank, and only if the app meets the FDIC's rules for that coverage | Usually a technology company, not a bank. Expect a strong app and few fees; rates vary widely and often carry conditions |
Credit unions use their own words for the same things: members rather than customers, shares rather than deposits, share certificates rather than CDs, and dividends rather than interest.
Is your money insured, and up to how much?
Deposits at banks are insured by the FDIC, and deposits at federally insured credit unions by the NCUA. Both cover at least $250,000 per depositor, per ownership category, at each institution, and both are backed by the full faith and credit of the United States government. The agency differs; the protection does not.
- Accounts at one institution, in one ownership category, share one limit. $250,000 at each of two institutions is covered at both.
- Joint accounts are covered separately from individual ones. Each owner's share of joint accounts is covered up to $250,000, which is how a couple can cover $500,000 in joint accounts at a single institution.
- A banking app is not itself insured. The money is covered only after the app deposits it at an insured bank, and only if the app meets the FDIC's requirements. Ask which bank holds the money and check that bank on the FDIC's BankFind.
Common questions
What is the difference between a CD and a share certificate?
Nothing in how the product works: a fixed rate for a fixed term, with a penalty for leaving early. A share certificate is what a credit union calls it. The differences are who may open one, since a credit union requires membership, and which agency insures it.
Should I use a savings account or a certificate?
It depends on when you need the money. Savings pays less and lets you withdraw any time. A certificate pays more and locks the money for the term. High-yield savings or a no-penalty certificate pays much of the certificate rate without the full lock.
Why is a checking account paying more than a savings account?
Rewards checking pays a high rate to encourage everyday use. It caps the balance that earns it and asks for activity every month, so the rate applies only up to the cap, and only in months every requirement is met.
Can anyone join a credit union?
Not automatically. Each credit union sets who may join: often anyone who lives, works, worships or goes to school in an area, or the employees of a company, the members of a group, and the families of existing members. Joining means opening a share savings account, usually with a small deposit.
Is my money as safe at a credit union as at a bank?
Yes, at a federally insured credit union, and most are. The NCUA insures their deposits to the same $250,000 level as the FDIC does at banks, and both are backed by the United States government. A small number of state-chartered credit unions use a private insurer instead, which is not government-backed. They have to say so when you open an account, on statements and in their branches.
Are online banks and banking apps safe?
An online-only bank with its own charter is insured exactly as a bank with branches is. A banking app is different: the app is not a bank, and the money is insured only once it sits at an insured partner bank, named in the account agreement.
