Compare Lease vs Buy Costs with a Free Calculator

Stop scrolling—if you’re trying to decide whether leasing or buying a car saves you money, this guide gives you one exact method to see the true cost in minutes. We’ll walk through the common pitfalls, hand you a ready‑to‑use spreadsheet, and show a real‑world example so you can instantly answer “lease or buy?” for any vehicle.

Why Simple Monthly Comparisons Fail

Most people look at the headline payment, do quick mental math, and call it a day. That quick compare lease vs buy costs ignores the hidden fees, interest, mileage limits, and resale value that can swing the total cost by thousands.

Leases often hide acquisition, disposition, and mileage‑overage fees.
Buying adds sales tax, registration, financing interest, and eventual depreciation.
Neither option should be judged without a total cost of ownership view that includes every line item.

Build Your Own Lease vs Buy Cost Spreadsheet

The easiest way to stop guessing is to plug every cost into a single worksheet. Below is the minimal data set you need; copy it into Excel or Google Sheets and let the formulas do the work.

Input	Lease	Buy
Down payment	$300	$2,000
Monthly payment	$350	$450
Term length (months)	36	60
Fees (acquisition, registration, etc.)	$650	$300
Interest rate / Money‑factor	3.5 % APR*	4 % APR
Mileage allowance	12,000 mi/yr	N/A
Overage charge	$0.25/mi	N/A
Estimated resale value	N/A	$12,000

*Convert the lease money‑factor to APR before entering it.

How the sheet works

Total lease cost = (Monthly × Term) + Down + Fees + Mileage overage.
Total purchase cost = (Monthly × Term) + Down + Fees + Interest – Resale value.

The result gives you a clear compare lease vs buy costs figure you can trust.

Step‑by‑Step Example

Using the numbers above:

Lease:
- Payments: $350 × 36 = $12,600
- Fees + Down: $300 + $650 = $950
- Expected mileage overage: 1,200 mi × $0.25 = $300
- Total lease cost: $16,300
Buy:
- Payments: $450 × 60 = $27,000
- Fees + Down: $2,000 + $300 = $2,300
- Interest (built into monthly rate) is already accounted for.
- Subtract resale value: $27,000 + $2,300 – $12,000 = $17,300

In this scenario the lease saves roughly $1,000 over five years, but if you drove more than the allowed miles or kept the car longer, the purchase would quickly become the cheaper option. Just change the mileage or term cells and the spreadsheet updates instantly.
