What is Vehicle Ownership Cost Comparison?
A buy vs lease comparison calculates the total cost of vehicle ownership versus leasing over 3-5 years including depreciation, interest, and maintenance.
The Formula
Buy TCO = Purchase Price โ Resale Value + Finance Interest + Maintenance Lease TCO = Monthly Payment ร Term + Excess Charges
Worked Example
A $35,000 car: buy with $7,000 down payment at 6.5% APR over 4 years, or lease at $450/month for 4 years.
- Buy total: $35,000 + $3,900 interest โ $18,000 resale = $20,900 net cost
- Buy maintenance: $1,800 over 4 years
- Buy TCO: $22,700
- Lease TCO: $450 ร 48 = $21,600 + $600 excess estimate = $22,200
๐ Leasing saves $500 over 4 years, but buying builds $18,000 in equity that offsets the next purchase.
Why This Matters
Cash flow management
Leasing requires lower monthly outlay and a smaller down payment, freeing capital for other business or personal uses.
Tax efficiency
Business lease payments are often fully tax-deductible while purchase depreciation follows IRS Section 179 and MACRS schedules.
Flexibility
Leasing allows vehicle upgrades every 2-4 years without selling hassle. Buying builds equity but locks capital.
Common Mistakes
โ Ignoring mileage limits
Lease excess mileage charges of $0.15-$0.30 per mile can add $1,500-$4,000. Estimate annual mileage accurately.
โ Not including maintenance
Bought vehicles need tires, brakes, and servicing. These costs erode the equity advantage of ownership.
โ Comparing monthly payments only
Low lease payments hide the total cost. Always compare total cost of ownership over the full period.
