Lease vs Buy Car Calculator 2026

The decision between leasing and buying a car depends on multiple factors: personal or business use, annual mileage, years of ownership, vehicle type (gas/hybrid/EV), tax status (personal/sole proprietor/LLC). This calculator compares Total Cost of Ownership (TCO) considering depreciation, maintenance, insurance, registration, fuel, and financing interest, with specific tax analysis for business users.

When Leasing Makes Sense

• Business use: Section 179 deduction up to $30,500 first year (2026 MACRS)
• High mileage >18,000 miles/year: lease payments include maintenance coverage
• Electric/hybrid vehicles: high technology depreciation risk transferred to lessor
• Short-term 2-3 years: heavy first-year depreciation penalty avoided
• Frequent car changes every 2-3 years: no resale/trade-in hassles
• Fixed monthly budget: predictable expense with warranty coverage

When Buying Makes Sense

• Ownership >5-7 years: buying breaks even then wins
• Low mileage <12,000 miles/year: leases have expensive per-mile caps
• Personal use no tax benefit: ownership has no lease deduction advantage
• Want to customize (wheels, paint, aftermarket mods - leases restrict)
• Cash available: eliminates financing interest costs
• High-reliability vehicles (Toyota, Honda): long-term ownership pays off

TCO Buying Components

• Financing interest: 7-9% APR over 3-7 years

• Registration/taxes: $100-800/year (varies by state)
• Maintenance: $600-1,500/year (oil changes, tires, brakes)
• Fuel: $1,500-3,000/year at 15,000 miles
• Tires: $500-1,200/year amortized
• Major repairs: $300-1,500/year after year 4-5
• Residual value: subtract from total

Lease Components

• Monthly payment: $250-900 depending on MSRP and mileage
• Down payment: 0-$3,000 (or $0 with "zero down" specials)
• Acquisition fee: $400-1,000 at signing

• Insurance required: comprehensive + collision at higher liability

US Depreciation by Vehicle Type

• Premium (BMW, MB, Audi): 20-25%/year (heavier depreciation)
• Trucks (F-150, Silverado): 10-14%/year (best retention)

US Business Deductibility 2026

• Standard mileage rate 2026: $0.70/mile (IRS annually)

• Lease advantage: $1,136 (5%)
• Verdict: equivalent economically, lease if want new car every 3 years

Frequently Asked Questions (FAQ)

Lease or buy: which saves more?

Depends on usage and tax. Personal 5-7 years: buying saves 5-15%. Business 3 years with Section 179: similar cost, lease preferred for simpler accounting. EVs: lease usually preferred due to tech depreciation. High mileage >18,000 mi/year: lease has per-mile overage penalties, buying better.

What's included in lease payment?

Includes: depreciation, financing (money factor), taxes. Does NOT include: insurance, fuel, maintenance (on most leases), tickets, damage. Some "lease all-inclusive" products (rare in US) include maintenance. Always check your specific lease agreement.

Can I buy the car at lease end?

Yes, via residual buyout. Price is set in contract (50-65% of MSRP typically). If market value > residual, buyout is good deal. If less, walk away. Increasingly common strategy: lease then buy out at end if vehicle performed well.

Do EVs really depreciate that fast?

First 1-2 years yes (25-30%/year) due to

• rapid tech improvements (range, battery capacity)
• used market uncertainty (limited history)
• battery degradation concern. Stabilizes from year 3. Primary reason EVs are commonly leased

What are hidden costs of buying?

• Major repairs year 4-5+: transmission, suspension, alternator: $800-3,000
• Private sale loss: -15-25% below KBB private-party value
• Time spent: private sale 20-40 hours (listings, viewings, paperwork)
• Seasonal tires: snow tires in snowy states $600-1,000 set

Business: lease or buy with Section 179?

Both work. Section 179 + Bonus Dep: immediate $30,500 deduction for SUVs >6,000 lbs, large tax benefit year 1 but then lower subsequent deductions. Lease: full monthly payment deductible, smoother cash flow, easier accounting. For stable businesses: Section 179. For growth/changing fleets: lease.

Can I terminate lease early?

Yes with early termination fees (typically 3-6 months remaining payments + disposition fee). Alternative: lease transfer services (Swapalease, LeaseTrader) let you transfer remaining lease to another driver, saving most of the penalty.
