Personal Finance Saving and Emergency Planning Flashcards

24 sample cards from the Saving and Emergency Planning deck

Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.

1. What is the future value of an ordinary annuity (regular equal deposits)?

   $$FV = PMT \times \frac{(1 + r)^{n} - 1}{r}$$ where $PMT$ is the periodic deposit, $r$ is the periodic rate, and $n$ is the number of periods.

2. Define a Certificate of Deposit (CD).

   A time deposit at a bank or credit union in which you lock a fixed sum for a fixed term (e.g., 6 months to 5 years) in exchange for a fixed, usually higher, interest rate. Funds are federally insured up to limits but committed until maturity.

3. What is the main trade-off and penalty associated with a CD?

   The trade-off is higher interest in exchange for reduced liquidity: withdrawing before the maturity date typically incurs an early-withdrawal penalty (often several months of interest). CDs suit money you will not need until a known future date.

4. What is a CD ladder, and what problem does it solve?

   A strategy of splitting money across several CDs with staggered maturity dates (e.g., 1-, 2-, 3-, 4-, and 5-year terms). As each matures you reinvest at the longest rung. It balances higher long-term rates with regular access to a portion of funds, reducing liquidity risk.

5. What is a Treasury bill (T-bill)?

   A short-term debt security issued by the U.S. government with maturities of one year or less (e.g., 4, 13, 26, or 52 weeks). It is sold at a discount and pays face value at maturity; it is considered essentially risk-free (backed by the government) and is highly liquid.

6. How does a T-bill generate a return if it pays no coupon?

   It is sold at a discount to its face (par) value and redeemed at full face value at maturity; the return is the difference. For example, buying a $\$1{,}000$ bill for $\$980$ yields $\$20$ at maturity.

7. What is a money market fund?

   A type of mutual fund that invests in very short-term, high-quality debt (T-bills, commercial paper, CDs). It aims to maintain a stable value (often $\$1$ per share), offers high liquidity and modest returns, and is used as a near-cash holding.

8. How does a money market fund differ from a money market deposit account (MMDA) at a bank?

   A money market deposit account is a bank product that is FDIC-insured. A money market fund is an investment product (not FDIC-insured, though very low risk) offered by brokerages/fund companies. Both are liquid and low-risk, but only the bank account carries deposit insurance.

9. What does 'matching savings to your time horizon' mean?

   Choosing where to keep money based on when you will need it: near-term funds go in liquid, stable, low-return vehicles (savings, money market, T-bills), while long-term funds can accept more risk for higher expected returns (stocks, bonds). The horizon dictates acceptable risk and liquidity.

10. For money needed in less than 1 year, which savings vehicles are most appropriate?

    Highly liquid, principal-stable options: high-yield savings accounts, money market accounts/funds, and short-term T-bills. Avoid volatile or locked instruments because the money must be available and safe.

11. For money needed in 1-3 years, which vehicles are commonly recommended?

    Short-term CDs, CD ladders, T-bills, and money market funds. These offer somewhat higher yields than savings accounts while keeping risk low and maturities aligned to the spending date.

12. For a goal 10 or more years away, why is a diversified stock-heavy portfolio often appropriate?

    A long horizon allows time to ride out market volatility and benefit from higher long-run expected returns and compounding. Short-term dips have time to recover before the money is needed, so accepting risk is reasonable.

13. What is liquidity, and why is it central to emergency savings?

    Liquidity is how quickly and cheaply an asset can be converted to cash without losing value. Emergency savings must be highly liquid because emergencies require immediate access; illiquid assets (real estate, locked CDs) fail this test.

14. What is the general relationship between risk, return, and liquidity across savings vehicles?

    Higher expected return generally requires accepting more risk and/or less liquidity. Savings accounts and T-bills are low-risk, liquid, low-return; CDs give up liquidity for slightly more yield; stocks offer higher potential return but higher risk and short-term volatility.

15. How does inflation affect the real return on savings, and what is the formula?

    Inflation erodes purchasing power, so the real return is the nominal return minus inflation. Approximately $r_{\text{real}} \approx r_{\text{nominal}} - \pi$, and precisely $$1 + r_{\text{real}} = \frac{1 + r_{\text{nominal}}}{1 + \pi}$$ where $\pi$ is the inflation rate.

16. What is the difference between APR and APY?

    APR (annual percentage rate) is the simple annual rate ignoring compounding. APY (annual percentage yield) reflects the effect of compounding within the year: $$APY = \left(1 + \frac{r}{n}\right)^{n} - 1$$ APY is the true earned rate and is always $\geq$ APR when compounding occurs more than once a year.

17. Compute the APY for a nominal rate of $6\%$ compounded monthly.

    $$APY = \left(1 + \frac{0.06}{12}\right)^{12} - 1 = (1.005)^{12} - 1 \approx 0.0617 = 6.17\%$$

18. What does continuous compounding formula look like, and when is it used?

    $$A = P e^{rt}$$ where $e \approx 2.71828$. It represents the theoretical limit of compounding infinitely often and gives the maximum possible growth for a given nominal rate, used as a benchmark in finance.

19. What is a high-yield savings account (HYSA), and why is it favored for emergency funds?

    An FDIC-insured savings account (often online) paying a significantly higher interest rate than a traditional bank savings account. It is favored because it combines full liquidity, principal safety, and a competitive yield that helps offset inflation.

20. How much does compounding frequency matter? Compare annual vs. monthly compounding at the same nominal rate.

    More frequent compounding yields slightly more because interest starts earning interest sooner. At $6\%$: annual gives $6.00\%$ APY, while monthly gives about $6.17\%$ APY. The effect grows with higher rates and longer horizons but is modest at typical savings rates.

21. What is the '50/30/20' budgeting guideline as it relates to saving?

    Allocate roughly 50% of after-tax income to needs, 30% to wants, and 20% to savings and debt repayment. It gives a simple structural target ensuring a meaningful, consistent savings rate.

22. Why is T-bill interest attractive from a tax standpoint in the U.S.?

    Interest on Treasury securities is exempt from state and local income taxes (though still subject to federal tax). This can raise the effective after-tax yield for investors in high-tax states compared with fully taxable CDs or savings accounts.

23. Rank these by typical liquidity from most to least liquid: a 5-year CD, a high-yield savings account, and a 4-week T-bill.

    Most liquid: high-yield savings account (instant access, no penalty). Next: 4-week T-bill (short maturity, sellable on the secondary market). Least liquid: 5-year CD (locked for 5 years with an early-withdrawal penalty).

24. Summarize the decision framework for where to keep a given pool of savings.

    Ask three questions: (1) When will I need it (time horizon)? (2) How much risk to principal can I tolerate? (3) How quickly must I access it (liquidity)? Short horizon and high liquidity needs point to savings/money market/T-bills; long horizons with tolerance for volatility justify higher-return, higher-risk investments.
