Banks offer four main account types, each balancing access, interest, and risk differently. Checking accounts give you instant access to your money; savings accounts store it at low interest; money market accounts pay more but require a minimum balance; and certificates of deposit (CDs) lock your money away for a fixed term in exchange for a guaranteed rate.
Checking account
A bank account that gives you easy access to your money through debit cards, cheques, and withdrawals. Think of it as your everyday spending account, the one your wages go into and your bills come out of.
Savings account
A bank account where you store money you do not need immediately but want to keep easily accessible. In simple terms, it is a holding pen for money you are not spending right now, earning a small amount of interest in the meantime.
Money market account (MMA)
A type of savings account that typically requires a higher minimum deposit but pays a higher interest rate than a standard savings account. It may also offer a debit card and limited cheque-writing. Think of it as a savings account with a few checking features and a better rate, provided you keep a larger balance.
Certificate of deposit (CD)
A savings certificate with a fixed maturity date and a specified fixed interest rate. In simple terms, you agree to leave your money untouched for a set period (six months, one year, five years) and the bank guarantees you a locked-in rate in return.
Primary purpose: daily transactions (paying bills, buying groceries, receiving wages)
Access methods: debit cards, cheques, ATMs, online and mobile banking
Benefits:
Immediate access to funds at any time
Online and mobile banking for convenience
Debit card for point-of-sale purchases
Risks and costs:
Monthly or maintenance fees at many banks
ATM withdrawal fees when using third-party machines
Overdraft fees if you spend more than the balance
Interest: typically earns little or no interest
Primary purpose: storing money you do not need immediately
Benefits:
Withdraw at any time, unlike longer-term investments
FDIC-insured (up to $250,000 per depositor per bank)
No maturity date or lock-in period
Risks and costs:
Low interest rates, meaning a poor real return after inflation
Some banks charge fees if the balance drops below a minimum
Key contrast with CDs: savings accounts offer flexibility; CDs offer a higher rate in exchange for locking funds away
Primary purpose: earning a better return on savings while retaining some transactional access
Benefits:
Higher interest rates than standard savings accounts
May include a debit card and limited cheque-writing
FDIC-insured
Risks and costs:
Require a minimum balance (often several thousand dollars)
Fees or rate reductions if the balance falls below the minimum
Best suited for: someone with a larger lump sum who wants a better rate but still needs occasional access
Primary purpose: locking in a guaranteed interest rate for a fixed term
Benefits:
Fixed interest rate for the life of the CD, protecting against rate drops
Generally higher rates than savings or money market accounts for the same bank
FDIC-insured
Risks and costs:
Money is locked away until maturity; early withdrawal usually triggers a penalty
Returns are typically lower than stocks or bonds over longer time horizons, reflecting the lower risk
Common terms: 6 months, 1 year, 2 years, 5 years
Students often think a savings account is the best place to grow money. It is not: savings rates typically fall below inflation, so your purchasing power can decline over time. Savings accounts are for safety and access, not wealth building.
Students sometimes confuse money market accounts with money market funds. A money market account is a bank product (FDIC-insured). A money market fund is an investment product (not FDIC-insured) and carries more risk.
Students frequently assume CDs always beat savings accounts. CDs offer a higher guaranteed rate, but if interest rates rise after you lock in, you are stuck at the lower rate or face an early withdrawal penalty.
Students occasionally believe checking accounts never charge fees. Most banks do charge monthly maintenance fees, though these can often be waived by maintaining a minimum balance or setting up direct deposit.
Be able to rank account types by liquidity (checking is most liquid, CD is least) and by typical interest rate (CD is highest, checking is lowest).
Know the trade-off: higher returns come with less access or higher minimum balances.
Understand what FDIC insurance covers and its limit ($250,000 per depositor per institution).
Expect questions that give a scenario (e.g. "a student saving for a car in two years") and ask which account type is most appropriate.
Be clear on the difference between a benefit and a risk for each account. Exams often list features and ask you to classify them.
True or false: A checking account typically earns the highest interest rate of the four account types. (False, it earns the lowest.)
Fill in the blank: A CD has a fixed ______ date and a fixed ______ rate. (Maturity; interest.)
True or false: You can withdraw from a savings account at any time without penalty. (True.)
Fill in the blank: A money market account usually requires a higher ______ than a standard savings account. (Minimum balance.)
True or false: CDs are riskier than stocks over the long term. (False, CDs are lower risk but also lower return.)
Q: A student wants to save money for a holiday in six months and needs to access it easily. Which account type is most appropriate?
A: A standard savings account. It earns some interest, has no lock-in period, and allows withdrawal at any time.
Q: What is the main advantage of a CD over a savings account?
A: A CD offers a higher, fixed interest rate that is guaranteed for the entire term. A savings account rate can change at any time and is typically lower.
Q: Why might someone choose a money market account over a regular savings account?
A: A money market account pays a higher interest rate, provided the account holder maintains the required minimum balance. It may also offer limited cheque-writing and debit card access.
Q: What are two risks associated with a checking account?
A: Monthly maintenance fees and ATM withdrawal fees from third-party machines. Overdraft fees are another common cost.
Q: Explain the liquidity trade-off across the four account types.
A: Checking is the most liquid (immediate, unlimited access) and pays the least interest. Savings is highly liquid with slightly more interest. Money market accounts offer moderate liquidity with a higher rate but require a minimum balance. CDs are the least liquid (funds are locked until maturity) but pay the highest guaranteed rate.
This material pairs with the Financial Institutions study notes. The exam may ask you to match institution types to the accounts they offer (e.g. which institutions issue CDs, which offer checking).
It also connects to personal finance topics such as budgeting, compound interest, and the time value of money. Understanding how different accounts balance risk, return, and liquidity is foundational for investment and saving decisions covered later in the course.
