Preparation
Lesson Narrative
Students dissect a standard paystub, calculating the mathematical difference between gross and net income. They will analyze mandatory tax withholdings and voluntary deductions to project realistic take-home pay.
Learning Goals
• Differentiate between Gross Income and Net Income.
• Identify mandatory payroll deductions (Federal, State, FICA).
• Estimate take-home pay percentages for budgeting.
Student Facing Learning Goals
Let's perform an autopsy on a paystub to see exactly where all our hard-earned money disappears to before we even get paid.
Student Facing Learning Targets
• I can define gross and net income.
• I can read a paystub.
• I can calculate the percentage of my money taken by taxes.
Required Academic Standards
National Jump$tart Standards:
• Earning Income (Standard 2): Analyze how taxes and other deductions affect income.
Glossary Entries
Gross Income: The total amount of money earned before any taxes or deductions are taken out.
Net Income: The amount of money you actually take home in your paycheck (Take-Home Pay).
FICA: Federal Insurance Contributions Act; mandatory taxes automatically deducted for Social Security and Medicare.
Withholding: The portion of an employee's wages that is not included in their paycheck but is instead remitted directly to the tax authorities.
Lesson
Warm Up
1.6.1: The Missing Money
Launch: Have students stand in randomized groups of 3 at vertical whiteboards. Present the prompt verbally. Give them 4 minutes.
Synthesis: Select two groups to share. Establish the baseline: You never actually see your "Gross" salary. You must base your entire financial life solely on your "Net" income.
Student Facing Task
You get your very first job paying $20 an hour. You work 50 hours in two weeks. You do the math: 50 x $20 = $1,000. On Friday, you open your paycheck and it only says $780.
1. Who took your missing $220?
2. If you signed a lease for an apartment that costs $900 a month assuming you made $1,000 per check, what is your immediate problem?
Activity 1
1.6.2: The Paystub Autopsy
Launch: Keep students at whiteboards. Project a realistic sample paystub. Give groups 8 minutes to map the deductions.
Synthesis: Have the class observe the boards. (Teacher Key: Differentiate between mandatory taxes (Federal/State/FICA) and voluntary deductions (Health Insurance/401k). The combination equals the wedge between gross and net).
Student Facing Task
Look at the sample paystub provided.
1. Identify the "Gross" pay number.
2. List the three mandatory taxes that the government legally forces the employer to withhold.
3. List two "voluntary" deductions the employee chose to pay for out of their check.
4. Identify the final "Net" pay number.
Activity 2
1.6.3: Net Income Projections
Launch: Present the job offer projection scenario. Give groups 8 minutes to estimate.
Synthesis: Facilitate a class debate. (Key: A safe rule of thumb is assuming 25-30% of your gross pay will vanish to taxes and basic benefits. Budgeting on gross income leads straight to bankruptcy).
Student Facing Task
You accept a job offering a "Gross Salary" of $60,000 a year. You want to build your monthly budget right now.
1. Calculate your Gross Monthly Income ($60k / 12).
2. Assume you will lose 25% of your gross income to taxes, health insurance, and retirement deductions. Calculate your estimated Net Monthly Income.
3. Which number must you use when deciding how much you can spend on rent?
Lesson Synthesis
Narrative: Bring the class back to their seats. Review the learning targets. Summarize: "Your gross income is a vanity number used for cocktail parties. Your net income is your reality. When you negotiate a salary, always mentally chop off a quarter of it before you make any lifestyle upgrades."
Cool Down
1.6.4: The Offer Letter
Narrative: This exit ticket serves as a formative assessment on budgeting reality. Teacher Rubric: A successful response must articulate that the $50,000 offer is gross income, and after FICA, federal, state, and benefit deductions, the actual cash deposited in the bank (net income) will be significantly lower.
Student Facing Task
A friend tells you, "I just got hired for $50,000 a year! That means I have exactly $4,166 to spend every single month!" Mathematically, explain to your friend why their budget is going to fail on their very first payday.
