Car Lease Calculator
Calculate your monthly lease payments and total lease costs
A Car Lease Calculator helps you determine monthly payments, total lease costs, and compare leasing vs. buying. It’s ideal for those who want to drive a new car without long-term ownership.
1. Key Lease Terms
A. Inputs Needed
Vehicle Price (MSRP) – Manufacturer’s Suggested Retail Price.
Negotiated Price – Discounted price after dealer negotiations.
Lease Term – Typically 24, 36, or 48 months.
Money Factor (Lease Interest Rate) – Expressed as a decimal (e.g., 0.0025 = ~6% APR).
Residual Value – Car’s estimated value at lease end (usually 50-60% of MSRP).
Down Payment & Fees – Includes capitalized cost reduction, acquisition fee, etc.
Annual Mileage Limit – Standard is 10,000–15,000 miles/year (excess incurs fees).
B. Outputs Calculated
✅ Monthly Payment
✅ Total Lease Cost (Payments + Fees)
✅ Effective Interest Rate (APR equivalent)
✅ Cost Per Mile
✅ Lease-End Buyout Price
2. How Lease Payments Work
Formula:
Monthly Payment = (Depreciation + Finance Charge) + Taxes
Depreciation Cost =
(Negotiated Price - Residual Value) / Lease Term
Finance Charge =
(Negotiated Price + Residual Value) × Money Factor
Taxes =
(Depreciation + Finance Charge) × Sales Tax Rate
Example Calculation
MSRP: $40,000
Negotiated Price: $36,000
Residual Value (58%): $23,200
Lease Term: 36 months
Money Factor: 0.0025 (~6% APR)
Down Payment: $3,000
Fees: $1,000
Step 1: Depreciation Cost($36,000 - $23,200) / 36 = **$355.56/month**
Step 2: Finance Charge($36,000 + $23,200) × 0.0025 = **$148/month**
Step 3: Pre-Tax Payment$355.56 + $148 = **$503.56/month**
Step 4: Add Taxes (8%)$503.56 × 1.08 = **$543.85/month**
Total Lease Cost = ($543.85 × 36) + $3,000 (down) + $1,000 (fees) = **$23,578.60**
3. Lease vs. Buy Comparison
Factor | Leasing | Buying |
---|---|---|
Monthly Cost | Lower | Higher |
Ownership | No equity | You own the car |
Mileage Limits | Yes (penalties) | No restrictions |
Maintenance | Often covered under warranty | Your responsibility |
Flexibility | Swap cars every few years | Long-term commitment |
4. Hidden Lease Costs to Watch For
⚠️ Disposition Fee ($300–$500) – Charged if you don’t buy the car at lease end.
⚠️ Excess Wear & Tear Fees – Dings, scratches, tire wear beyond "normal."
⚠️ Early Termination Fee – Costly if you end the lease early.
⚠️ Gap Insurance – Needed in case of a total loss (some leases include it).
5. When Leasing Makes Sense
✔ You want a new car every 2–4 years.
✔ You drive under mileage limits.
✔ You prefer lower monthly payments.
✔ Business tax deductions (some leases qualify).
