## Review Notes

### Topic 5.1: Taxes, Net Income, and Budgeting

Individuals pay taxes to federal, state, and local governments. The U.S. federal income tax is progressive: higher income brackets face higher marginal rates. Employers withhold income taxes and payroll taxes (Social Security and Medicare) from each paycheck. At year end, individuals file a tax return and either pay the remaining balance or receive a refund. Self-employed individuals must submit estimated taxes themselves. A pay stub shows gross income, mandatory deductions, voluntary deductions, and net income. Pretax deductions (such as contributions to a 401(k) or health savings account) lower taxable income before taxes are calculated, which reduces the tax owed.

- **Progressive tax**: A tax structure in which higher income levels are taxed at higher marginal rates, as in the U.S. federal income tax.
- **Tax deduction**: An amount subtracted from gross income before calculating taxes owed; examples include mortgage interest, retirement contributions, and charitable donations.
- **Tax credit**: An amount subtracted directly from taxes owed, such as the child tax credit or earned income tax credit; more valuable dollar-for-dollar than a deduction.
- **Gross income vs. net income**: Gross income is total pay before deductions; net income is take-home pay after all mandatory and voluntary deductions are subtracted.
- **Capital gains tax**: A tax on profit from selling an asset; typically taxed at a lower rate than ordinary income and reported on the annual income tax return.

**Checkpoint:** Given a pay stub showing a $3,500 gross biweekly salary with federal income tax, Social Security, Medicare, and a pretax 401(k) contribution withheld, can you calculate net income and explain why the 401(k) contribution reduces the federal income tax withheld?

Type | What it reduces | Example
--- | --- | ---
Tax deduction | Taxable income | Mortgage interest, 401(k) contribution
Tax credit | Taxes owed directly | Child tax credit, earned income tax credit
Pretax deduction | Taxable income before withholding | Health insurance premium, HSA contribution

### Topic 5.2: Managing Personal Risk

Insurable risks are losses due to chance that are quantifiable and statistically predictable. The three categories are personal risk (health, injury), property risk (home, car), and liability risk (harm caused to others). Individuals transfer risk to an insurer by paying a premium; in exchange, the insurer reimburses covered losses after the policyholder meets the deductible. Coverage decisions depend on legal requirements (most states require auto liability insurance; mortgage lenders require property insurance), risk tolerance, and number of dependents. Individuals with low risk tolerance choose lower deductibles and higher premiums; those with higher risk tolerance accept higher deductibles to lower premiums. Financial fraud risks include predatory lending, phishing, identity theft, and online scams. Protection strategies include comparing loan terms, freezing credit, and verifying the credibility of financial offers before sharing personal information.

- **Insurable risk**: A risk involving potential loss due to chance that is quantifiable and statistically predictable, making it possible for an insurer to price a policy.
- **Premium**: The regular payment (monthly, semi-annual, or annual) an individual makes to maintain an insurance policy.
- **Deductible**: The amount the policyholder must pay out of pocket before the insurer covers the remaining loss.
- **Liability risk**: An insurable risk involving financial responsibility for harm or damage caused to another person or their property.
- **Predatory lending**: Deceptive or aggressive loan practices that trap borrowers in unfavorable terms; countered by comparing offers and consulting nonprofit credit counselors.

**Checkpoint:** A household with two young children and a mortgage is deciding between a health insurance plan with a $500 deductible and $400 monthly premium versus one with a $2,000 deductible and $250 monthly premium. What factors should guide their recommendation?

Insurance type | Risk covered | Legal requirement?
--- | --- | ---
Health insurance | Medical costs and preventive care | Varies; often employer-provided
Auto insurance | Vehicle damage and liability | Required in most U.S. states
Homeowner's insurance | Property damage and liability | Required by mortgage lenders
Renter's insurance | Personal property and liability for renters | Not typically required by law
Life insurance | Income replacement for dependents | Not required

### Topic 5.3: Saving and Investing for Education, Housing, and Retirement

Long-term financial goals typically include funding postsecondary education, buying a home, and saving for retirement. Education is financed through savings, federal and private student loans, scholarships, grants, and work-study; federal loans generally offer lower rates and more flexible repayment. Home purchases require a down payment and a mortgage; lenders evaluate credit history and income. Retirement savings grow through tax-advantaged accounts: 401(k) plans (employer-sponsored), traditional and Roth IRAs (individual), and taxable brokerage accounts. Compounding means that returns earned on an investment generate their own returns over time, so starting early dramatically increases long-term wealth. Diversification across asset classes (stocks, bonds, savings vehicles) reduces portfolio risk. Real return accounts for inflation, which erodes purchasing power. Risk tolerance and time horizon together determine the appropriate asset mix: longer horizons allow more exposure to higher-risk, higher-return assets like stocks.

- **Compounding**: The process by which investment returns generate their own returns over time, making early saving disproportionately valuable.
- **Diversification**: Spreading investments across different asset types to reduce the impact of any single asset losing value.
- **Time horizon**: The length of time an individual plans to hold an investment before needing the funds; longer horizons support higher-risk investments.
- **Real return**: The rate of return on an investment after adjusting for inflation; what actually increases purchasing power.
- **529 plan**: A tax-advantaged savings account designed to fund qualified education expenses; contributions grow tax-free when used for education.

**Checkpoint:** A 25-year-old wants to retire at 65 and also save for a home purchase in 5 years. How should risk tolerance and time horizon differ between the retirement portfolio and the home down payment fund, and which account types are most appropriate for each goal?

Account type | Goal | Tax advantage | Key limit or rule
--- | --- | --- | ---
401(k) | Retirement | Pretax contributions; tax-deferred growth | Employer-sponsored; annual contribution limit
Traditional IRA | Retirement | Pretax contributions; tax-deferred growth | Individual; income limits may apply
Roth IRA | Retirement | After-tax contributions; tax-free growth | Income limits; tax-free withdrawals in retirement
529 plan | Education | Tax-free growth for qualified education expenses | State-sponsored; penalties for non-education use

## Practice Preview

### Multiple-choice practice

- **AP-style practice question**: Skill Category 1 - Concept Application | A homeowner hosts a neighborhood cookout. A guest trips over a garden hose left in the yard and breaks her arm, incurring $5,800 in medical expenses. That same evening, a grease fire damages the homeowner's deck, causing $4,300 in repair costs. The homeowner also misses two days of work as a result of dealing with the incident, losing $600 in wages. Which answer correctly classifies all three financial losses the homeowner faces?
- **AP-style practice question**: Skill Category 2 - Entrepreneurship | A commission-based sales employee earns 5% of her total sales each pay period. In one period she closes $28,000 in sales. Her pay stub lists Social Security tax, Medicare tax, federal income tax, and state income tax as separate line items, along with a $95 voluntary contribution to an employer-sponsored retirement savings plan. Which line on her pay stub represents her gross income?
- **AP-style practice question**: Skill Category 2 - Entrepreneurship | An employee earns $3,600 gross income per pay period. Her pay stub shows a $180 pretax dental and vision insurance premium and a $120 pretax flexible spending account contribution for dependent care. After these pretax deductions, what amount is subject to mandatory tax withholdings?
- **AP-style practice question**: Skill Category 2 - Entrepreneurship | A salaried employee's annual compensation of $62,400 is paid in 24 semi-monthly installments. Her pay stub for one period lists federal income tax of $195, state income tax of $78, Social Security tax of $161.50, and Medicare tax of $37.78. She also has a $60 post-tax life insurance premium deducted. What is her net income for this pay period?
- **AP-style practice question**: Skill Category 2 - Entrepreneurship | Two employees each have $2,500 gross income per pay period. Employee X has a $200 pretax health insurance premium and a $150 post-tax union dues payment. Employee Y has a $200 post-tax health insurance premium and a $150 pretax union dues payment. Assuming identical mandatory tax rates, which statement correctly compares their pay stubs?
- **AP-style practice question**: Skill Category 2 - Entrepreneurship | Rodrigo's employer offers him a group health insurance plan where the company pays 60% of the monthly premium and Rodrigo pays the remaining 40%. After a routine physical, Rodrigo's insurer covers the full cost of the visit. Which pair of insurance concepts does this scenario illustrate?

### FRQ practice

- **Customer service scaling for e-commerce business**: FRQ 4 – Business Decision | Customer service scaling for e-commerce business

## Key Terms

- **gross income**: Total earnings during a pay period before any mandatory or voluntary deductions are subtracted.
- **payroll tax**: Mandatory taxes withheld from wages to fund Social Security and Medicare; both the employee and employer contribute.
- **pretax deduction**: A voluntary deduction taken from gross income before taxes are calculated, such as a 401(k) contribution or health savings account deposit, which lowers taxable income.
- **budget**: A plan that allocates net income across spending categories, savings, and debt payments to help a household meet its financial goals.
- **deductible**: The out-of-pocket amount a policyholder must pay before the insurer covers a loss; higher deductibles correspond to lower premiums.
- **compounding**: The process by which investment returns generate their own returns over time, making early and consistent saving disproportionately powerful.
- **diversification**: Spreading investments across different asset types (stocks, bonds, savings vehicles) to reduce the risk that any single loss significantly damages the portfolio.
- **time horizon**: The length of time before an investor needs to access funds; longer horizons support higher-risk, higher-return asset allocations.
- **rate of return**: The percentage gain or loss on an investment over a period, used to compare the performance of different financial assets.
- **real return**: The rate of return on an investment after subtracting the inflation rate; the measure of actual purchasing power gained.
- **401(k)**: An employer-sponsored retirement savings account funded with pretax contributions that grow tax-deferred until withdrawal.
- **IRA**: An individual retirement account that allows individuals to save for retirement with tax advantages; traditional IRAs use pretax dollars, Roth IRAs use after-tax dollars.
- **529 plan**: A state-sponsored, tax-advantaged savings account designed to fund qualified postsecondary education expenses.
- **down payment**: The portion of a home's purchase price paid upfront from savings; a larger down payment reduces the mortgage amount and may eliminate private mortgage insurance.
- **mortgage**: A long-term loan used to finance a home purchase, secured by the property itself; lenders evaluate credit history and income before approval.

## Common Mistakes

- **Confusing tax deductions with tax credits**: A deduction reduces taxable income, so its value depends on your tax bracket. A credit reduces taxes owed dollar-for-dollar. Students often treat them as equivalent, but a $1,000 credit saves more than a $1,000 deduction for most households.
- **Mixing up gross income and net income on a pay stub**: Gross income is total earnings before any deductions. Net income is what actually hits your bank account. When building a budget, you must use net income, not gross income, as your starting point.
- **Assuming higher risk tolerance always means better outcomes**: Higher-risk assets have higher expected returns but also higher potential losses. A household saving for a home purchase in two years should not hold mostly stocks, because a market downturn could force them to sell at a loss right when they need the funds.
- **Forgetting that a lower deductible means a higher premium**: Students sometimes recommend low deductibles as universally better. In practice, a lower deductible transfers more risk to the insurer, so the insurer charges a higher premium. The right choice depends on the household's risk tolerance and cash reserves.
- **Ignoring inflation when evaluating investment returns**: A savings account earning 2% interest does not grow your purchasing power if inflation is 3%. Real return equals nominal return minus inflation, and it is the figure that actually matters for long-term goal planning.

## Exam Connections

- **Scenario-based recommendation tasks**: AP Business with Personal Finance exam questions frequently present a household profile (income, dependents, goals, risk tolerance, time horizon) and ask you to recommend a course of action. For Unit 5, this means recommending insurance coverage levels, investment account types, or asset allocations with explicit reasoning tied to the household's specific situation rather than general rules.
- **Interpreting financial documents**: Pay stub interpretation is a core Unit 5 skill. Exam tasks may ask you to identify specific line items, calculate net income, or explain why a pretax deduction reduces the tax withheld. Practice reading sample pay stubs and labeling each component before the exam.
- **Explaining trade-offs using financial concepts**: Unit 5 FRQ tasks often require you to explain a trade-off rather than just name a concept. For example, explaining why a longer time horizon justifies a higher-risk portfolio requires connecting compounding, potential for recovery after a downturn, and the risk of needing to liquidate assets at a loss. Build the habit of stating the concept, applying it to the scenario, and naming the consequence.

## Final Review Checklist

- **Final Unit 5 review checklist**: Use this checklist to confirm you can handle every major skill in Unit 5 before your exam.
- **Identify and distinguish tax types**: Name and explain income tax, capital gains tax, payroll taxes (Social Security and Medicare), property tax, and sales tax, and describe who pays each and when.
- **Explain progressive taxation and tax adjustments**: Describe how marginal tax brackets work, and distinguish between a tax deduction (reduces taxable income) and a tax credit (reduces taxes owed directly).
- **Read and interpret a pay stub**: Calculate net income from gross income by subtracting mandatory deductions (income tax, Social Security, Medicare) and voluntary deductions (health insurance, pretax retirement contributions), and explain why pretax deductions lower the tax withheld.
- **Categorize insurable risks and match insurance types**: Classify a given risk as personal, property, or liability, and identify the appropriate insurance product. Explain how deductible level, premium cost, and risk tolerance interact in coverage decisions.
- **Recognize and counter financial fraud**: Identify predatory lending tactics, phishing, and identity theft, and describe specific protective actions such as comparing loan terms, freezing credit, and verifying financial offers.
- **Apply compounding, diversification, and real return**: Explain why starting early increases long-term wealth through compounding, how diversification reduces portfolio risk, and why real return (adjusted for inflation) is the relevant measure of investment growth.
- **Recommend an investment plan based on goals and time horizon**: Given a household's education, housing, or retirement goal, time horizon, and risk tolerance, recommend an appropriate mix of financial assets and account types (401(k), IRA, 529 plan, savings account, stocks, bonds).

## Study Plan

- **Step 1: Taxes and pay stubs (Topic 5.1)**: Read the Topic 5.1 guide on taxes, net income, and budgeting. Practice labeling each line of a sample pay stub as gross income, a mandatory deduction, or a voluntary deduction, and calculate net income. Then distinguish a tax deduction from a tax credit using a concrete example like the child tax credit versus a mortgage interest deduction.
- **Step 2: Insurance and fraud protection (Topic 5.2)**: Read the Topic 5.2 guide on managing personal risk. For each insurance type (health, auto, homeowner's, renter's, life), identify the risk category it covers and whether it is legally required. Practice recommending coverage levels for a sample household by weighing deductible, premium, risk tolerance, and number of dependents. Review the fraud protection strategies as a short list.
- **Step 3: Long-term saving and investing (Topic 5.3)**: Read the Topic 5.3 guide on saving and investing for education, housing, and retirement. Work through a compounding example comparing a saver who starts at 22 versus one who starts at 32. Then practice matching account types (401(k), Roth IRA, 529 plan) to specific goals and time horizons, and explain how diversification and real return factor into the recommendation.
- **Step 4: Practice and synthesis**: Use the 25+ available practice questions to test yourself across all three topics. For FRQ practice, work through the 3 available FRQs and focus on structuring recommendations with explicit reasoning: name the concept, apply it to the household scenario, and explain the trade-off.
