Lease Calculator
Calculate fixed monthly lease payments or solve inversely for the effective interest rate (IRR/APR) on equipment, commercial assets, and vehicles.
Lease Calculator
The Lease Calculator can be used to calculate the monthly payment or the effective interest rate on a lease. If the interest rate is known, use the "Fixed Rate" tab to calculate the monthly payment. If the monthly payment is known, use the "Fixed Pay" tab to calculate the effective interest rate. Or use the Auto Lease Calculator regarding auto lease for U.S. residents.
• Use Fixed Rate to solve for monthly payment from asset value, residual value, term, and interest rate.
• Use Fixed Pay to reverse-solve for the implied annual interest rate (IRR) from a known monthly payment.

Principal vs. Interest
What is a Lease & How Does It Work?
A lease is a contractual agreement where the asset owner (the lessor) grants temporary operational use of equipment, vehicles, or property to another party (the lessee) in exchange for structured periodic payments over a defined term.
Depreciation Coverage
Rather than paying for the entire asset, lease payments primarily cover the asset's depreciation portion ($V - R$) over the lease term, plus finance interest and service fees.
Residual Value Buyout
At lease expiration, lessees typically have the contractual option to purchase the asset outright for its predetermined residual value ($R$), return the asset, or roll into a new lease.
Tax & Accounting Benefits
For commercial businesses, operating lease installments are often 100% tax-deductible as business operating expenses, preserving liquidity without tying up capital in heavy fixed assets.

Lease Calculator — Frequently Asked Questions
Q1 What is the fundamental difference between a lease and a loan? ▾
With a loan, you borrow money to purchase full ownership of the asset, repaying principal and interest until you own it outright. With a lease, you pay for the temporary use and depreciation of the asset (Asset Value minus Residual Value) plus financing fees over a set timeframe.
Q2 What is residual value in a lease contract? ▾
Residual value is the estimated fair market value of the leased asset at the end of the lease term. A higher residual value results in lower monthly lease payments because less of the asset principal depreciates during the lease.
Q3 What happens at the end of a lease? ▾
At the end of a typical lease agreement, lessees generally have three choices: purchase the asset for the agreed-upon residual buyout price, return the asset to the lessor, or renew/extend the lease under renegotiated terms.
Q4 How does the "Fixed Pay" mode calculate the effective interest rate? ▾
The Fixed Pay solver uses the Newton-Raphson numerical root-finding algorithm to determine the Internal Rate of Return (IRR) where the discounted cash flows of the monthly payments and future residual value exactly equal the initial asset value.
Q5 Are commercial equipment lease payments tax-deductible? ▾
In many jurisdictions, operating lease payments can be fully deducted as business operating expenses, which can reduce taxable net income and preserve working capital compared to debt-financed capital asset acquisitions.
