Lease vs Buy Equipment Calculator

How to Use This Tool

Follow these steps to generate an accurate lease vs buy comparison for your business equipment:

1. Gather your buying details: equipment purchase price, expected down payment, loan terms from your lender, annual maintenance costs, and how long you plan to use the equipment (useful life).
2. Collect your leasing details: monthly lease payment, lease term, security deposit, initiation fees, and any maintenance costs not covered by the lease.
3. Set your comparison period (the number of years you want to compare both options) and your corporate tax rate for tax savings calculations.
4. Click the Calculate Comparison button to see a detailed breakdown of costs, tax savings, and a final recommendation.
5. Use the Reset Form button to clear all inputs and start a new calculation.

Formula and Logic

This calculator uses Total Cost of Ownership (TCO) adjusted for tax savings to compare leasing and buying over your chosen comparison period. Below is the core logic:

Buying Cost Calculation

• Loan Amount = Purchase Price - Down Payment
• Monthly Loan Payment = Loan Amount * (monthly interest rate * (1 + monthly interest rate)^number of payments) / ((1 + monthly interest rate)^number of payments - 1)
• Total Buying Cost (pre-tax) = Down Payment + (Monthly Loan Payment * 12 * Loan Term) + (Annual Maintenance * min(Comparison Period, Useful Life))
• Tax Savings = (Total Interest Paid + Straight-Line Depreciation) * Corporate Tax Rate
• Net Buying Cost = Total Buying Cost (pre-tax) - Tax Savings

Leasing Cost Calculation

• Total Leasing Cost (pre-tax) = Security Deposit + Initiation Fee + (Monthly Lease Payment * 12 * Lease Term) + (Annual Maintenance * min(Comparison Period, Lease Term))
• Tax Savings = (Total Lease Payments) * Corporate Tax Rate (lease payments are fully tax-deductible as operating expenses)
• Net Leasing Cost = Total Leasing Cost (pre-tax) - Tax Savings

All calculations use straight-line depreciation for buying, and assume tax deductions are applied in the year expenses are incurred. For simplified reporting, we compare costs over the same user-defined period to ensure an apples-to-apples comparison.

Practical Notes

When evaluating lease vs buy decisions for your business, consider these industry-specific factors:

• Cash Flow Impact: Leasing typically requires lower upfront costs, which preserves working capital for inventory, marketing, or payroll. Buying ties up capital in equipment that depreciates over time.
• Tax Implications: Buying allows you to deduct depreciation and loan interest, while leasing lets you deduct 100% of lease payments as operating expenses. Consult your accountant to align with current IRS or local tax regulations.
• Equipment Obsolescence: For fast-evolving equipment (e.g., e-commerce servers, point-of-sale systems), leasing avoids the risk of owning outdated equipment. For long-lasting equipment (e.g., industrial machinery, delivery vehicles), buying may be more cost-effective long-term.
• Balance Sheet Impact: Operating leases are typically off-balance sheet, which can improve financial ratios like debt-to-equity. Buying adds an asset and a liability (loan) to your balance sheet.
• Maintenance and Repairs: Many leases include maintenance coverage, which reduces unexpected costs. Buying requires you to cover all maintenance, which can vary year-to-year.

Why This Tool Is Useful

Small business owners and entrepreneurs often face high-stakes equipment decisions with limited financial data. This tool eliminates guesswork by:

• Quantifying hard-to-track costs like tax savings and long-term maintenance
• Providing an unbiased recommendation based on your specific numbers
• Allowing you to test multiple scenarios (e.g., different loan terms, tax rates, comparison periods)
• Helping you justify decisions to stakeholders, investors, or lenders with detailed breakdowns

It is tailored for real-world business use cases, from e-commerce sellers buying packaging equipment to contractors leasing construction tools.

Frequently Asked Questions

Should I include sales tax in the purchase price?

Yes, enter the total amount you will pay to acquire the equipment including sales tax, delivery fees, and setup costs in the Purchase Price field. This ensures your cost calculations are accurate.

What if my lease has a buyout option at the end?

If your lease includes a buyout option, add the buyout cost to the Total Leasing Cost calculation manually, or run a separate calculation for buying at the buyout price. This tool compares standard lease and buy scenarios, but you can adjust the purchase price to match a lease buyout for custom comparisons.

How do I find my corporate tax rate?

Your corporate tax rate is the percentage of profit you pay in taxes, set by your federal, state, and local governments. For U.S. C-corporations, the federal rate is 21%, but your total rate may be higher with state taxes. Consult your tax professional for your exact rate.

Additional Guidance

Before making a final decision, consider these non-financial factors that this calculator does not account for:

• Customization needs: Buying equipment lets you modify it to fit your business processes, while leased equipment may have restrictions.
• Usage limits: Many leases have annual usage caps (e.g., miles for vehicles, hours for machinery) that incur overage fees.
• End-of-term options: Leases may offer options to upgrade, extend, or return equipment, while buying requires you to resell or dispose of the equipment.
• Credit impact: Loan payments for buying build business credit, while lease payments may not be reported to credit bureaus depending on the lessor.

Always review lease agreements and loan terms carefully before signing, as hidden fees (e.g., early termination fees, excess wear charges) can change your total costs.
