Lease Car vs Buy Calculator
Compare the total cost of leasing versus buying over your chosen time horizon. This model estimates cash outflow and equity impact.
How to use this lease vs buy calculator
This calculator is designed to answer one practical question: what will leasing or buying actually cost me over the period I care about? Instead of focusing only on monthly payment, it includes major ownership and leasing costs that often get ignored in quick dealership comparisons.
Start by setting your analysis period (for example, 36, 48, or 60 months). Then enter your best estimate for both buy and lease scenarios. When you click calculate, you get:
- Total estimated cost for buying over your horizon
- Total estimated cost for leasing over your horizon
- Estimated monthly effective cost for each option
- A simple “which is cheaper” recommendation
Why monthly payment alone is misleading
A lease frequently looks cheaper because the monthly payment is lower. But that does not automatically mean the total cost is lower. Leasing can include upfront cash due at signing, acquisition fees, disposition fees, mileage penalties, and possible wear-and-tear charges.
Buying can look expensive because monthly payments may be higher, but you are building equity in an asset. At the end of your time horizon, the car still has value. The calculator subtracts that estimated value and adjusts for remaining loan balance to produce a fairer comparison.
What this model includes
Buying side
- Purchase price and down payment
- Loan interest and principal payments made during your horizon
- Sales tax on purchase
- Annual maintenance, insurance, and fees
- Estimated resale value after depreciation
- Remaining loan balance (if loan is not fully paid by horizon)
Leasing side
- Monthly lease payment plus payment tax
- Due at signing and acquisition fees for each lease cycle needed
- Disposition fees for completed lease terms
- Mileage overage costs based on your driving habits
- Wear-and-tear estimate
- Annual insurance, maintenance, and fees
Interpreting your result
If buying appears cheaper, that usually means your expected resale value and long-term use are working in your favor. This is common for drivers who keep cars longer, drive more than average, or choose reliable models with strong resale demand.
If leasing appears cheaper, that often means you value frequent vehicle replacement, stay within mileage limits, and avoid long-term repair risk. Leasing can also make sense when heavily incentivized by manufacturer programs.
When leasing tends to make sense
- You want a newer vehicle every 2–3 years
- You drive close to or below mileage limits
- You prioritize warranty coverage and predictable short-term costs
- You can secure a low-money-factor, low-fee lease offer
When buying tends to make sense
- You plan to keep the car for many years
- You drive high annual mileage
- You want freedom to modify or personalize the car
- You want to eliminate payments eventually and lower long-run transportation cost
Tips to improve either outcome
If you buy
- Negotiate purchase price first, financing second
- Compare loan APR offers from multiple lenders
- Choose a reliable model with stronger resale value
- Avoid extending loan term just to reduce monthly payment
If you lease
- Negotiate the selling price (yes, even on a lease)
- Target lower acquisition fees and reduced drive-off cash
- Match mileage allowance to your real driving pattern
- Inspect and repair minor damage before lease turn-in
Important notes
This tool provides an estimate, not a guarantee. Real-world outcomes depend on taxes by state, exact lease contract terms, insurance market changes, your maintenance history, and actual resale prices. Use this as a decision framework and then verify details with your dealer, lender, and insurer.
