How Lease vs. Buy Calculation Works

The calculation compares total costs for both options:

Lease Total = Down Payment + (Monthly Payment × Term)
Buy Total = Down Payment + (Monthly Payment × Term) - Residual Value
Buy Monthly = P × [r(1+r)^n] / [(1+r)^n - 1]
P=Principal, r=Monthly Rate, n=Months

Where:

  • Vehicle Price = Purchase price of the vehicle
  • Down Payment = Initial payment made upfront
  • Term = Lease/buy period in months
  • Residual Value = Estimated value at end of term
  • Interest Rate = Annual percentage rate for financing

The estimated value of a vehicle at the end of a lease or loan term.

Total Cost of Ownership

Includes purchase price, financing costs, depreciation, maintenance, insurance, and taxes.

Equity Building

The value you gain when buying a vehicle that you don't get with leasing.

Frequently Asked Questions (FAQ)

Q: What is the difference between leasing and buying a car?

A: Leasing is essentially renting a car for a specific period (typically 2-4 years) with monthly payments, after which you return the vehicle. Buying means you purchase the car outright or through financing, becoming the owner and building equity.

Q: When is it better to lease rather than buy?

A: Leasing may be better if you prefer driving newer cars with the latest features, want lower monthly payments, drive moderate miles, and don't mind not owning an asset. It's also suitable for business use where payments may be tax-deductible.

Q: When is it better to buy rather than lease?

A: Buying is better if you want to build equity, plan to keep the car long-term, drive high mileage, want the freedom to modify the vehicle, or prefer the security of ownership. While monthly payments are typically higher, you own the asset at the end.

Q: How does depreciation affect the lease vs. buy decision?

A: Depreciation significantly impacts both options. New cars lose value rapidly in the first few years. In a lease, you're only paying for the depreciation during the lease term. When buying, you absorb the full depreciation but own the asset at the end.

Q: What factors should I consider when deciding between leasing and buying?

A: Key factors include your financial situation, driving habits (mileage), how long you plan to keep the vehicle, preference for new cars, need for ownership equity, maintenance preferences, and potential tax implications.

Q: Are there tax benefits to leasing vs. buying?

A: For business use, both leasing and buying may offer tax deductions. Lease payments are typically fully deductible as a business expense. When buying for business, you can deduct depreciation and interest. For personal use, tax benefits are generally limited.
