**TCO categories (comprehensive 2025 breakdown)**: **Purchase/financing costs**: Vehicle purchase price, sales tax (avg 7.5%), registration/title fees ($200-800), destination charge ($1,000-2,000), dealer fees ($500-1,500), loan interest (5.5-8.5% APR 2025), or lease payments. **Depreciation**: New car 20% first year + 15%/year years 2-5 (50-60% in 5 years total), used car 10-15%/year, luxury/EV higher rates 60-70%, trucks/SUVs retain better 40-45% loss. **Insurance**: Full coverage $1,500-2,500/year (new), liability-only $800-1,200/year (older), age 25-65 best rates, urban vs rural 2× difference, collision/comprehensive required if financed. **Fuel costs**: Gas at $3.50/gallon (2025 avg), 12,000 miles/year ÷ MPG × price, EV at $0.15/kWh ÷ efficiency (3.5 mi/kWh avg) = $514/year vs $1,750/year gas (25 MPG). **Maintenance**: Routine oil changes $50-100 × 3/year, tire rotation $25 × 2/year, brakes $400/30k miles, tires $800/40k miles, transmission $300/30k miles, EV minimal ($300/year avg vs $1,200 gas). **Repairs**: Warranty years 1-3 = $200/year, years 4-7 = $800-1,500/year, luxury brands 2-3× higher, extended warranty $1,500-3,000 upfront. **Taxes/fees**: Annual registration $80-300, inspection $25-50/year, tolls/parking variable. **Total 5-year example (Honda Civic)**: $28,000 purchase - $10,000 depreciation + $1,800 tax + $1,200 fees + $4,800 interest + $7,500 insurance + $8,750 fuel + $3,500 maintenance + $2,500 repairs + $1,000 registration = **$49,050 total**, **$9,810/year**, **$0.82/mile** (12k miles/year).

**New vs used TCO comparison (2025 Toyota RAV4 example, 5-year ownership)**: **New $35,000 RAV4**: Purchase $35,000 + tax/fees $3,200 + depreciation $17,500 (50%) + insurance $10,000 (higher full coverage) + financing $6,500 (6.5% on $28k, 5yr) + fuel $9,000 + maintenance $4,000 + repairs $1,500 = **$51,700 total**, **$0.86/mile**.

Resale value $17,500 after 5 years. **3-year-old used $23,000 RAV4** (was $35k new): Purchase $23,000 + tax/fees $2,100 + depreciation $8,050 (35% next 5 years) + insurance $7,500 (lower liability) + financing $4,200 (7.5% on $18k, 5yr) + fuel $9,000 + maintenance $5,500 (older) + repairs $4,500 (more repairs) = **$40,850 total**, **$0.68/mile**.

Resale value $14,950 after 5 years. **Savings**: Used saves $10,850 (21% lower TCO) but higher repair risk. **Break-even analysis**: If used car needs $3,000+ unexpected repair in years 1-2 (transmission, engine), savings erode to $7,850.

If new car offers 0% APR financing (saves $6,500 interest), gap narrows to $4,350. **Sweet spot**: 2-3 year old certified pre-owned (CPO) with warranty coverage, avoid 20% first-year depreciation ($7,000), gain warranty protection, finance at CPO rates (6-7%). **Risk factors for used**: No powertrain warranty, unknown maintenance history, higher interest rates, potential lemon. **When new wins**: 0% financing offers, manufacturer rebates >$3,000, brands with low depreciation (Toyota/Lexus), planning 10+ year ownership (dilute initial depreciation), warranty peace of mind worth premium.

**EV vs Gas TCO comparison (5-year, 12,000 miles/year, 2025 pricing)**: **Tesla Model 3 Long Range ($45,000)**: Purchase $45,000 - $7,500 fed tax credit = $37,500 net + $2,625 tax/fees + depreciation $20,250 (45%, EV depreciation improved) + insurance $6,000 (higher EV) + charging $2,570 ($0.15/kWh × 3,429 kWh/year) + maintenance $1,500 (minimal, no oil, brakes, transmission) + repairs $500 (less wear) = **$45,945 total**, **$0.77/mile**. **Honda Accord ($32,000)**: Purchase $32,000 + $2,400 tax/fees + depreciation $16,000 (50%) + insurance $4,500 (lower gas) + gas $8,750 ($3.50/gal, 27 MPG) + maintenance $6,000 (oil, brakes, exhaust) + repairs $2,500 = **$56,150 total**, **$0.94/mile**. **EV savings**: $10,205 (18% lower) over 5 years, **$2,041/year**, breakeven at 3.2 years. **Key assumptions verified (2025 reality)**: Federal tax credit $7,500 (income limits apply, <$150k single, <$300k joint), electricity $0.15/kWh national average (varies $0.10-0.40 by state), home charging 80% (cheap overnight), Supercharger 20% ($0.40/kWh = $1,714/year if 100% public), EV depreciation improved to 45% (was 60% in 2022-2023), maintenance savings $750-1,000/year (Consumer Reports 2024), insurance 10-30% higher (expensive repairs, parts). **When gas wins**: High-mileage drivers >20k miles/year (battery degradation accelerates), renters without home charging (public charging 2-3× cost), cold climates (range loss 20-40%), rural areas (limited charging infrastructure), road-trippers (charging time penalty 30 min/200 miles vs 5 min gas). **When EV wins**: Home charging available, low-mileage drivers (maximize tax credit per mile), high electricity cost differential ($0.10 vs $4/gallon equivalent), tax credit eligible, planning 8-10 year ownership (dilute higher purchase price).

**Lease vs buy TCO (2025 BMW 330i, 3 years, 12k miles/year)**: **Leasing $45,000 BMW**: $3,000 down + $550/month × 36 = $22,800 payments + $1,000 fees + insurance $5,400 + gas $5,250 + maintenance $900 (covered in lease) + $0 repairs (warranty) = **$32,350 total**, **$0.90/mile**.

Return car, $0 equity, must lease/buy next vehicle. **Buying $45,000 BMW**: $5,000 down + $750/month × 60 = $50,000 payments (includes interest 6.5%) + $3,375 tax/fees + insurance $6,750 (required full) + gas $8,750 + maintenance $4,500 + repairs $1,500 = **$74,875 gross**, but **own car worth $27,000** after 5 years = **$47,875 net cost**, **$0.80/mile** (5 years). **Analysis at 3-year mark**: Lease total $32,350 (3 years), Buy total $33,000 payments + $10,125 costs - $31,500 value = $11,625 net (own car worth $31,500). **Lease advantages**: Lower monthly payment ($550 vs $750), no repair risk, always under warranty, drive new car every 3 years, sales tax on payments only (not full price), easier to afford luxury. **Buy advantages**: Build equity, no mileage limits, can customize/modify, can sell anytime, lower insurance possible (drop collision on old car), total cost lower over 10+ years. **Lease disadvantages**: Never own, mileage limits (12k = $0.25/mile overage penalty), wear-and-tear charges ($500-2,000), early termination impossible/expensive, gap insurance required, higher insurance always. **Buy disadvantages**: Higher monthly payment, depreciation risk, repair risk after warranty, responsible for selling. **Lease makes sense**: Drive <12k miles/year, like new cars every 3 years, business tax deduction (100% deductible if >50% business use), luxury brands (avoid repair costs), always want warranty coverage. **Buy makes sense**: High mileage >15k/year, keep cars 7+ years, customize vehicle, want to own outright, concerned about long-term costs, lower credit score (lease requires 700+, buy accepts 650+).
