What Is a Lease Calculator?
A lease calculator estimates your monthly lease payment, commonly for vehicles, based on the negotiated price, expected residual (future) value, down payment, money factor (leasing's version of an interest rate), and lease term.
How to Use the Lease Calculator
- Enter the negotiated price (capitalized cost) of the vehicle or equipment.
- Enter the residual value (its estimated worth at lease end, usually provided by the leasing company).
- Enter your down payment (cap cost reduction).
- Enter the money factor and lease term.
- Enter your local sales tax rate.
Lease Payment Formula
The money factor is leasing's equivalent of an interest rate. To convert it to an approximate annual interest rate, multiply by 2,400.
Worked Example
Depreciation fee: ($35,000 − $2,000 − $18,000) ÷ 36 ≈ $416.67
Finance fee: ($35,000 − $2,000 + $18,000) × 0.00125 ≈ $63.75
Base payment: $416.67 + $63.75 ≈ $480.42
With 7% tax: total monthly payment ≈ $514.05
Understanding Your Results
Depreciation Fee covers the vehicle's expected loss in value during the lease. Finance Fee is the leasing company's profit margin (similar to interest). Together they form your base payment, before sales tax is applied.
Common Mistakes to Avoid
- Confusing money factor (a small decimal like 0.00125) with a standard percentage interest rate.
- Not negotiating the capitalized cost — it's negotiable just like a purchase price.
- Ignoring mileage limits and excess wear fees, which can add significant cost at lease end.
Frequently Asked Questions
It's leasing's equivalent of an interest rate, expressed as a small decimal. Multiply it by 2,400 to get an approximate equivalent annual percentage rate.
It's the vehicle's (or equipment's) estimated value at the end of the lease term, set by the leasing company — a higher residual value generally means a lower monthly payment.
Yes — the capitalized cost (negotiated price) is generally negotiable, similar to a purchase price. Residual value and money factor are typically set by the leasing company based on the specific vehicle and your credit.
Most leases charge a per-mile fee for mileage beyond the agreed limit, which can add up significantly if you drive more than expected.
Leasing often has lower monthly payments than financing a purchase, but you don't build equity and may face mileage and wear restrictions — the better choice depends on your driving habits and financial goals.
