What is a Lease vs. Buy Calculator?

A lease vs. buy calculator is a free automotive financial tool that helps you compare the total costs of leasing versus buying a vehicle. It calculates all expenses associated with each option including monthly payments, fees, interest, depreciation, and equity to help you make an informed decision based on your financial situation and driving needs.

This calculator helps with cost comparison (understand total expenses for leasing vs. purchasing), financial planning (budget for monthly payments and long-term costs), decision making (choose the best financing option for your situation), value analysis (evaluate which option provides better financial value), and scenario comparison (test different terms, prices, and conditions).

How Lease vs. Buy Calculation Works

The Comparison Formulas
Industry-standard lease and buy calculations

Lease Total Cost:

Down Payment + (Monthly Payment × Term) + Fees + Excess Mileage

Buy Total Cost:

Down Payment + (Monthly Payment × Term) - Residual Value

Buy Monthly Payment:

P × [r(1+r)^n] / [(1+r)^n - 1]

P=Principal, r=Monthly Rate, n=Months

Where:

  • Vehicle Price = Purchase price or MSRP
  • Down Payment = Initial payment upfront
  • Term = Lease/buy period in months
  • Residual Value = Estimated value at term end
  • Interest Rate = Annual percentage rate

Example:

$30,000 car, $3,000 down
Lease (36 mo): $400/mo = $17,400 total
Buy (60 mo, 4.5% APR): $503/mo = $15,202 net cost
Result: Buying saves $2,198 (12.6%)

Key Concepts Explained

Depreciation
The decrease in vehicle value over time, which significantly impacts both leasing and buying costs.
  • New cars lose 20-30% in first year
  • Leasing: You only pay for depreciation during lease
  • Buying: You absorb all depreciation but keep the asset
  • Fast-depreciating cars better for leasing short-term
Residual Value
The estimated value of a vehicle at the end of a lease or loan term.
  • Predetermined in lease contracts (buyout price)
  • Your equity if you buy and keep the vehicle
  • Higher residuals = lower lease payments
  • Affects total cost comparison significantly
Equity Building
The value you gain when buying a vehicle that you don\'t get with leasing.
  • Leasing: $0 equity - you return the car
  • Buying: Typically $15,000-20,000 after 5 years
  • Equity can be used for next vehicle down payment
  • Building equity makes buying cheaper long-term
Total Cost of Ownership
Includes all expenses: payments, fees, insurance, maintenance, and depreciation.
  • Leasing: Typically higher insurance requirements
  • Buying: Higher initial payments, lower total cost
  • Lease hidden fees can add $2,000-5,000

Benefits of Using This Calculator

Informed Decisions

Make better vehicle financing choices based on real cost comparisons. See exactly how much you\'ll spend and what you\'ll own with each option. Avoid buyer\'s remorse by understanding the full financial picture before signing.

Financial Planning

Budget accurately for vehicle expenses and understand long-term costs. Plan for lease-end fees or loan payoff. Compare how different down payments, terms, and rates affect your total cost over the entire ownership period.

Value Optimization

Determine which option provides better financial value for your specific situation. Understand the trade-offs between lower monthly payments (lease) and long-term savings (buy). See how mileage, term length, and interest rates affect the comparison.

Scenario Analysis

Compare different vehicles, terms, and financing options side-by-side. Test how changes in down payment or interest rates affect your decision. Explore multiple scenarios to find the perfect financing strategy for your budget and goals.

Factors That Affect Your Results

1. Vehicle Depreciation Rate

Different vehicles depreciate at different rates, significantly impacting both lease and buy costs. Luxury vehicles and EVs depreciate faster, making leasing potentially better short-term, while economy cars with slow depreciation favor buying.

Slow Depreciation

Toyota, Honda, Subaru - 50% retained after 5 years. Buying strongly recommended.

Average Depreciation

Ford, Nissan, Hyundai - 35-45% retained. Buying usually better if keeping 5+ years.

Fast Depreciation

Luxury, EVs - 25-30% retained. Leasing can limit depreciation exposure short-term.

2. Interest Rates and Money Factor

Financing rates dramatically affect the total cost of buying. A 1% difference in APR equals $1,500+ over a 5-year loan. Leases use a "money factor" (interest rate ÷ 2400 = money factor). For example, 4.8% APR = 0.002 money factor. Shop rates aggressively - credit unions often beat dealer financing by 1-2%, saving thousands.

3. Mileage and Usage Patterns

Higher mileage strongly favors buying. Leases typically allow 10,000-15,000 miles/year with $0.20-0.30/mile excess fees. If you drive 20,000 miles/year, that\'s $1,500-2,250 in annual excess fees. Over 3 years, that\'s $4,500-6,750 extra - often more than the savings from lower lease payments. High-mileage drivers should almost always buy.

4. How Long You Keep Vehicles

If you like new cars every 2-3 years, leasing can make sense with lower payments and no trade-in hassle. However, if you keep vehicles 5+ years, buying is dramatically cheaper. After 5 years of payments, you own a vehicle worth $15,000-20,000. If you lease continuously, payments never end and you never build equity. The break-even is typically 3-4 years.
