01Buy vs. Lease

Understanding the fundamental difference before you step foot on a lot

🤍
A note from Mom & Dad
You don't have to do this alone.
Buying your first car is a big decision — and we don't expect you to figure it out by yourself. We're always here to walk through the numbers with you, look at listings together, sit in the passenger seat on a test drive, or come along to the dealership when it's time. Just ask. We're rooting for you.

Buying means you own the car — eventually. Leasing means you're renting it for a set period and returning it. Neither is universally better — but for most first-time car-getters on a budget, a reliable used car purchased outright or financed is almost always the smarter long-term financial move.

Buying

New or used — you own it

  • You build equity — the car is yours to sell or keep
  • No mileage limits — drive as much as you need
  • Modify it however you want
  • Once paid off, no more monthly payments
  • Lower insurance requirements than leasing
  • Higher monthly payments (especially new)
  • Responsible for all repairs after warranty
  • Depreciation — value drops the moment you drive off
Best for: People who drive a lot, plan to keep the car long-term, or want to eventually own something outright. Buy used to avoid the steepest depreciation hit.

Leasing

You drive it — then return it

  • Lower monthly payment than buying new
  • Always driving a newer car under warranty
  • Less maintenance worry — warranty covers most issues
  • Walk away at the end of the term
  • You never own it — no equity built
  • Mileage limits (typically 10,000–15,000/year) — overages cost extra
  • Wear and tear fees at lease end
  • Higher insurance requirements (full coverage required)
  • Early termination is very expensive
Best for: People who drive limited miles, want a new car every 2–3 years, and can handle the ongoing payment cycle. Rarely the best financial choice for a first car on a tight budget.

New vs. Used — the depreciation reality

New Car
Loses ~20% of value the moment you drive it off the lot. Loses another 10–15% in year two. A $35,000 car may be worth $22,000 after two years — but you're still making payments on $35,000. Financing a new car at a high interest rate is one of the most expensive financial decisions young adults make.
Used Car (2–4 Years Old)
The original owner absorbed the steepest depreciation. You get a reliable, relatively modern vehicle at a significantly lower price. A certified pre-owned (CPO) vehicle from a manufacturer offers a warranty similar to new. This is the strongest first-car financial move for most young adults.
Which Path Are You Considering and Why?

02Research Your Car

Find a real vehicle — used or new — and document it here

Search these sites for real listings. Look at used cars 2–4 years old with under 50,000 miles for the best value. Always run a Carfax or AutoCheck report on any used vehicle before buying.

03Financing Calculator

What your monthly payment actually looks like — and what it costs you total

The monthly payment is not the price of the car. When you finance, you pay the purchase price plus interest over the loan term. A $20,000 car financed at 7% for 60 months costs you over $23,700 total. Run the numbers before you agree to anything.

04True Monthly Cost of a Car

The payment is just the beginning — add everything up

The monthly payment is the most visible cost — but not the biggest. Insurance, fuel, maintenance, registration, and parking can easily double what you thought you were paying. Calculate the real number before you commit.

Monthly Car Expense Notes Est. Monthly
Car Payment (Principal + Interest) From the calculator above
$
Auto Insurance Get quotes — see Section 5. First-time drivers often pay more.
$
Fuel Miles driven/month ÷ MPG × gas price per gallon
$
Oil Changes & Routine Maintenance Budget ~$100/month set-aside for oil changes, tires, brakes over time
$
Registration & Taxes (monthly set-aside) Annual registration ÷ 12. Varies by state — often $100–$500/year.
$
Parking Monthly parking at home or work — often overlooked
$
Emergency Repair Fund (set-aside) Budget $50–$100/month for unexpected repairs
$
True Total Monthly Car Cost $0

This total should be under 15% of your monthly take-home pay. If it's not — consider a less expensive car, a larger down payment, or a longer loan term.

05Auto Insurance

What you're required to carry — and what you actually need

State Required
Liability Coverage
Covers damage you cause to other people's cars and property, and injuries to others in an accident you caused. Required in nearly every state — minimums vary. Never drive without it.

Full Protection
Add-Ons Worth Considering
Uninsured motorist coverage protects you if someone hits you with no insurance. Roadside assistance is cheap and invaluable. Gap insurance covers the difference if your car is totaled but worth less than you owe.

How to get the best rate

Get at least 3 quotes. Use Progressive, Geico, State Farm, USAA (military families), and your renter's insurance provider. The same coverage can vary by hundreds of dollars between companies.
Bundle with renter's insurance. Insuring both with the same company typically saves 5–15% on each policy.
Choose a higher deductible. Raising your deductible from $500 to $1,000 can meaningfully lower your monthly premium. Only do this if you can afford the deductible in an emergency.
Ask about discounts. Good student discount, defensive driving course, low mileage, paperless billing, and pay-in-full discounts are all commonly available.
Consider staying on your parents’ policy — but understand the trade-off. While you’re still living at home or the car is garaged there, staying on their policy is often significantly cheaper. However, once you move out permanently and own your own car, getting your own separate policy is worth discussing with your family. On your own policy, any claim stays with you and doesn’t affect their rates or expose their assets. Talk it through before deciding.

06Reflect On It

What is your real car plan?

📊
Update Your Budget — Chapter 8
Your true monthly car cost belongs in your budget under Transportation.
Enter your total from Section 4 — car payment, insurance, fuel, maintenance, registration, and parking — into your Chapter 8 budget under Needs → Transportation. Now recalculate. Is your total needs category still under 50% of income? Is transportation alone under 15% of take-home? If not, something has to change — the car, the loan, or something else in the budget.
