Lease vs Buy Equipment Calculator

Leasing equipment vs buying is a classic economic comparison: lease trades cash flow flexibility for higher total cost; buying trades upfront cash for lower long-term cost. Which wins depends on equipment useful life, lease terms, and your cash flow situation.

Typical lease structure: monthly payment × 36 months covers 100-130% of retail price, with no ownership at end. Buying outright costs retail price upfront but equipment belongs to you with remaining useful life. For equipment with 5-7 year useful life and 3-year lease, buying typically saves 30-60% over lease.

Lease advantages: no large upfront cost, often includes maintenance, easy to upgrade at end. Buy advantages: cheaper long-term, residual value, no monthly obligation. Tax treatment differs depending on jurisdiction and use (business vs personal) — may affect decision but beyond the scope of basic comparison.

How to use it

Input purchase price, monthly lease cost, lease term in months, and remaining useful life of equipment after lease would end. The tool shows total cost of each option over equivalent total period.

What the result means

Total cost over equivalent period shows which option costs less. Savings amount quantifies the difference. Short useful life post-lease (1-2 years) makes lease more competitive. Long useful life (5+ years) strongly favours buying.

Decision tool, not financial advice.

A worked example

Try the defaults: purchase price of 3,000, monthly lease cost of 110, lease term of 36, useful life after lease of 36. The tool returns Buy. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Purchase Price, Monthly Lease Cost, Lease Term, and Useful Life After Lease. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the option with the lower calculated total changes.

The formula behind this

Lease total is monthly × term. Buy total is purchase price, with remaining value implied by months of useful life after lease ends. Buy wins if purchase price amortised over total useful life (lease term + remaining) is less than monthly lease. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Reading payback vs outright cost

Payback tells you when you're break-even, not whether the purchase is a good idea. A short payback on something you barely use is still a loss. Pair the number with an honest count of expected usage.

What this doesn't capture

Purchase decisions rarely come down to payback alone. Reliability, time saved, enjoyment, and alternatives outside the calculation all matter. The figure gives you the money side cleanly so you can weigh it against everything else honestly.
