Lease vs Buy Equipment Calculator

How to Use This Tool

Enter the purchase price of the equipment you’re evaluating, then fill in all lease-related terms including monthly payment and down payment. Add annual maintenance costs for owned equipment, expected residual value after the comparison period, and your corporate tax rate. If you plan to finance the purchase with a loan, include the interest rate and loan term. Click Calculate to see a full cost breakdown, and use Reset to clear all fields. You can copy the full results to your clipboard for records.

Formula and Logic

We calculate pre-tax and after-tax costs for both leasing and buying over the specified lease term:

• Lease Costs: Total lease payments (down payment + monthly payment * term) minus tax savings from deducting lease payments as business expenses.
• Cash Purchase Costs: Purchase price plus prorated annual maintenance over the term, minus tax savings from deducting the full purchase price and maintenance, minus residual value recouped from selling the equipment.
• Financed Purchase Costs: Total loan payments (principal + interest) plus prorated maintenance, minus tax savings from deducting loan interest and maintenance, minus residual value.

All tax savings are calculated as (deductible amount * corporate tax rate). We assume straight-line depreciation for tax purposes over the comparison period, and that all lease payments and maintenance costs are fully tax-deductible in the year they are incurred.

Practical Notes

For small business owners and e-commerce sellers, consider these category-specific factors when interpreting results:

• Equipment with fast technological obsolescence (e.g. office laptops, fulfillment scanners) often favors leasing to avoid holding outdated assets.
• Heavy machinery or vehicles with long useful lives typically have higher residual values, making purchasing more cost-effective for long-term use.
• Lease payments are fully deductible as operating expenses, while purchased equipment depreciation deductions may be spread over multiple years depending on tax jurisdiction.
• E-commerce sellers should factor in peak season demand: leasing additional fulfillment gear for Q4 may be more cost-effective than purchasing underused equipment.

Why This Tool Is Useful

Entrepreneurs and procurement teams often face pressure to minimize upfront costs while maintaining operational flexibility. This tool removes guesswork by quantifying all direct and tax-related costs for both options, including often-overlooked factors like residual value and maintenance. It helps avoid overpaying for equipment, aligns procurement decisions with cash flow needs, and provides auditable records for accounting teams.

Frequently Asked Questions

Can I use this tool for used equipment?

Yes, simply enter the actual purchase price of the used equipment and adjust the residual value to reflect its expected resale value after the comparison period. Used equipment may have lower purchase prices but higher maintenance costs, which you can factor in via the annual maintenance field.

How do I handle lease buyout options?

If your lease includes a buyout option at the end of the term, add the buyout price to the total lease cost and compare it to the cash purchase cost. You can also enter the buyout price as the residual value if you plan to purchase the equipment after leasing.

What if my tax rate changes during the lease term?

Use your average expected corporate tax rate over the full comparison period for the most accurate results. You can run multiple calculations with different tax rates to model best and worst-case scenarios.

Additional Guidance

Always consult with a certified public accountant (CPA) or tax professional before making major equipment procurement decisions, as tax laws vary by jurisdiction and business structure. For equipment with variable usage (e.g. seasonal machinery), consider running calculations for multiple term lengths to see how costs change over time. Keep records of all input values used in this calculator to support tax filings and internal procurement approvals.
