Lease Payment Calculator
Calculate monthly lease payments for equipment or vehicles and compare the total cost of leasing vs. buying outright.
What Is a Lease Payment Calculator?
A lease payment calculator computes your monthly lease obligation by combining two components: the depreciation charge (the portion of the asset's value you "use up" during the lease) and the finance charge (interest on the depreciating balance). It then compares the total cost of leasing to buying the same asset outright with financing. The monthly lease payment formula is: (Cap Cost - Residual) / Term + (Cap Cost + Residual) x Money Factor. The first part covers depreciation; the second covers financing. The "money factor" is the leasing equivalent of an interest rate -- multiply it by 2,400 to get the approximate APR. A money factor of 0.00208 equals approximately 5.0% APR. Leasing makes financial sense when: (1) the asset depreciates rapidly (technology, vehicles), (2) you need to preserve capital for higher-return investments, (3) you want to upgrade frequently, or (4) the lease payments are tax-deductible as a business expense. Buying makes more sense when: (1) you plan to use the asset beyond the lease term, (2) interest rates on purchase financing are lower, or (3) you value ownership and equity buildup.
How to Use This Calculator
Enter the Asset Value
This is the manufacturer's suggested retail price (MSRP) or the negotiated purchase price. For vehicles, the "capitalized cost" (cap cost) may differ from MSRP after dealer markup or discount.
Set the Residual Percentage
The residual value is what the asset will be worth at lease end, expressed as a percentage of the original value. Vehicles typically have residuals of 40-60% for 36-month leases. Equipment may be 10-30%. Higher residual means lower monthly payment because you are financing less depreciation.
Enter the Interest Rate
Enter the annual interest rate. If you have a money factor, multiply by 2,400 to convert. Business equipment leases typically carry 5-12% implicit interest rates depending on credit quality.
Compare Lease vs. Buy
The calculator shows the total cost of leasing (all payments plus any purchase option) against buying with financing. Remember to factor in the tax treatment: lease payments are 100% deductible as a business expense, while purchased assets are depreciated (or expensed under Section 179).
Key Concepts
Residual Value
The projected value of the asset at the end of the lease term. A higher residual means a lower monthly payment but a higher purchase-option price if you want to buy the asset at lease end. Residuals are set by the lessor based on depreciation projections.
Money Factor
The leasing equivalent of an interest rate, expressed as a small decimal (e.g., 0.00208). Multiply by 2,400 to approximate the APR (0.00208 x 2,400 = 4.99%). Lower money factor = lower financing cost.
Capitalized Cost (Cap Cost)
The effective purchase price used to calculate lease payments. Cap cost = negotiated price + dealer add-ons + taxes rolled in - down payment - trade-in value. Negotiating the cap cost down is the most effective way to lower your lease payment.
Section 179 Deduction
IRS provision allowing businesses to expense the full purchase price of qualifying equipment in the year of purchase (up to $1,220,000 in 2024) rather than depreciating it over multiple years. This tax benefit is available for purchases but not for standard leases (though $1 buyout leases may qualify).
Expert Insights
Negotiate the Cap Cost, Not Just the Payment: Dealers can manipulate lease payments by adjusting multiple variables (cap cost, money factor, residual, term). Focus on negotiating the capitalized cost down first, then verify the money factor against published rates. A $2,000 reduction in cap cost saves roughly $56/month on a 36-month lease.
$1 Buyout Leases Are Essentially Loans: A lease with a $1 purchase option at the end is functionally a loan -- you will own the asset. These are common for business equipment and may qualify for Section 179 deduction. Compare the implicit interest rate against conventional financing; $1 buyout leases often carry higher rates.
Business Leases Have Tax Advantages: Operating lease payments are 100% deductible as a business expense in the period incurred. This can be more tax-efficient than purchasing and depreciating over 5-7 years, especially for businesses in higher tax brackets. However, under ASC 842, leases over 12 months must appear on the balance sheet.
