Lesson Narrative
Students move beyond the monthly auto loan payment to calculate the Total Cost of Ownership (TCO) for a vehicle. They will analyze the hidden costs of transportation, including fuel efficiency (MPG) math, routine maintenance (oil changes, tires), state registration fees, and insurance, proving that a car's sticker price is only a fraction of its true cost.
Learning Goals
• Calculate the annual fuel cost of a vehicle based on MPG and commute distance.
• Estimate annual maintenance and registration costs.
• Calculate the true monthly Total Cost of Ownership (TCO) of a vehicle.
Student Facing Learning Goals
• Let's calculate exactly how much money a car steals from your budget every month after you buy it.
Student Facing Learning Targets
• I can calculate how much gas will cost me for a year.
• I can list the hidden costs of owning a car.
• I can calculate the Total Cost of Ownership (TCO).
Required Academic Standards
National Jump$tart Standards:
• Planning and Money Management (Standard 1): Develop a plan for spending and saving.
Glossary Entries
Total Cost of Ownership (TCO): The purchase price of an asset plus the costs of operation.
MPG (Miles Per Gallon): A measure of a vehicle's fuel efficiency.
Registration Fee: A mandatory tax paid to a state to legally operate a vehicle on public roads.
Maintenance: Routine financial costs required to keep a vehicle safely operational (e.g., oil, tires, brakes).
Lesson
Warm Up
5.5.1: The $300 Mirage
Launch: Have students stand in randomized groups of 3 at vertical whiteboards. Present the prompt verbally or project it. Give them 4 minutes.
Synthesis: Select two groups to share. The car payment is just the entry fee. Insurance, gas, and repairs often double the monthly cost.
Student Facing Task
Student-Facing Task: You have exactly $300 a month left in your budget. You find a car loan that costs exactly $300 a month. Mathematically, why can you NOT afford this car?
Activity 1
5.5.2: The Fuel Math
Launch: Keep students at whiteboards. Project commute scenario. Give groups 8 minutes.
Synthesis: Have the class observe the boards. (Teacher Key: 20 miles/day x 20 days x 12 months = 4,800 miles. 4,800 / 20 MPG = 240 gallons. 240 x $4 = $960/year. Divide by 12 = $80/month). Contrast an SUV with a hybrid to show how MPG impacts monthly cash flow.
Student Facing Task
Student-Facing Task: Let's calculate gas costs. You commute 10 miles to work and 10 miles back, 20 days a month, all year. Your SUV gets 20 Miles Per Gallon (MPG). Gas costs $4.00 a gallon.
1. Calculate your total miles driven for the year.
2. Divide total miles by MPG to find total gallons used.
3. Multiply total gallons by gas price. What is your monthly gas bill?
Activity 2
5.5.3: The TCO Calculation
Launch: Present TCO scenario. Give the whiteboard groups 10 minutes to calculate.
Synthesis: Facilitate a class debate. (Key: Loan ($400) + Ins ($150) + Gas ($80) + Maint ($100) + Reg ($25) = $755/month). Discuss how buying a cheap used car often increases maintenance costs, while buying a new car increases insurance and loan costs.
Student Facing Task
Student-Facing Task: Calculate the true monthly Total Cost of Ownership (TCO) for this vehicle. Convert all yearly expenses to monthly numbers first.
• Auto Loan: $400/month
• Insurance: $1,800/year
• Gas: $80/month
• Maintenance Sinking Fund: $1,200/year
• State Registration: $300/year
1. What is the actual, mathematical monthly cost of operating this car?
Lesson Synthesis
Lesson Synthesis (5 min)
Narrative: Bring the class back to their seats. Review the student-facing learning targets. Summarize: "A car is not an investment; it is a liability that actively consumes your wealth. Keep your TCO as low as mathematically possible."
Cool Down
5.5.4: The Electric Decision
Narrative: This exit ticket serves as a formative assessment comparing upfront vs recurring costs.
Teacher Rubric: Must articulate that while the electric car has a higher loan payment, the elimination of gas and oil changes lowers the TCO, making it mathematically cheaper month-to-month.
Student Facing Task
Student-Facing Task: Car A costs $20,000 (Gasoline). Car B costs $25,000 (Electric). Why might Car B actually have a lower monthly Total Cost of Ownership (TCO) despite having a much higher monthly loan payment?
