Car Lease vs Buy: Which Is Better?

How car lease vs buy works in practice

A car lease is long-term rental — you pay for depreciation plus interest (money factor) during the lease term, then return the vehicle. Buying means financing or paying cash, owning the asset, and keeping it after the loan is paid off.

The goal is not to memorize every term — it is to know which inputs matter and what outcome you are aiming for.

So what: When you can explain this in your own words, you are far less likely to accept a bad quote, fee, or assumption.

A real scenario worth running

$35,000 MSRP vehicle, 36-month lease vs 60-month purchase at 6.9% APR. Step by step: Lease: ~$2,000 down + ~$420/month × 36 = ~$17,120 total (no equity) → Buy: $3,500 down + ~$610/month × 60 = ~$39,900 total — own $18k+ value car → After 3 years: lease walk away; buyer has equity and no payment years 6–10. Bottom line: Lease costs less per month short-term; buying wins if you keep the car 5+ years.

So what: Plug your own numbers into the same logic before you decide.

Lease vs buy: the fundamental difference

Leasing is long-term rental — you pay for depreciation plus interest during the term, then return the car. Buying means financing or paying cash, building equity, and keeping the vehicle after the loan is paid. Leasing offers lower monthly payments; buying wins for long-term ownership (5+ years).

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

How lease payments are calculated

Monthly lease ≈ (Cap cost − Residual value) ÷ Term + Finance charge + Tax

Cap cost = negotiated price (like purchase price)
Residual = predicted value at lease end
Money factor = lease interest rate (× 2,400 ≈ APR)

You pay only for the portion of the car's value you use — not the full price.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Worked example: 36-month lease vs 60-month purchase

$35,000 MSRP vehicle, 6.9% purchase APR:

After 3 years: lessee starts over; buyer has equity and no payment in years 6–10 if they keep the car.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Side-by-side comparison

Who should lease?

Leasing suits drivers who:

• Want a new car every 2–3 years
• Drive predictable, low mileage (under 12,000/year)
• Prefer lower monthly payments and newer safety tech
• Can treat payments as a transportation expense, not an investment

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Who should buy?

Buying suits drivers who:

• Keep cars 5+ years
• Drive high mileage (15,000+ miles/year)
• Want no restrictions on modifications or wear
• Prefer zero car payment after the loan is paid off

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

End-of-lease options

Always compare buyout price to Kelley Blue Book / market listings before deciding.

Money factor: lease APR in disguise

Money factor 0.0025 × 2,400 ≈ 6% APR equivalent. Negotiate cap cost (like purchase price) — the residual is often set by the manufacturer and harder to change.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Common mistakes

1. Lease payment based on residual value — you pay for depreciation only..
2. Typical lease: 36 months, 10,000–15,000 miles/year limit — this quietly costs you over time.
3. Excess mileage fees ~$0.15–$0.30/mile; wear-and-tear charges apply — this quietly costs you over time.
4. Buying at 5+ years often lower total cost than leasing repeatedly — this quietly costs you over time.
