How it's calculated

How the lease vs. cash calculator works

This calculator compares the true financial cost of leasing a vehicle against paying cash outright over the same hold period. The cash scenario subtracts the estimated resale value you recover when you sell, then adds the opportunity cost — the investment return you give up by tying up capital in a depreciating asset. The lease scenario totals all payments and fees with no residual offset.

Cash total cost = Vehicle price Resale value + Opportunity cost of capital
Opportunity cost = Vehicle price × ((1 + r)^t 1) [r = annual rate, t = years]
Lease total cost = Drive-off + (Monthly payment × Term) + Disposition fee
Net advantage = |Cash total Lease total|

At a 5% annual return, $30,000 in cash grows to approximately $34,729 over three years — meaning the buyer forgoes about $4,729 in investment gains. Adding that to the net purchase cost (price minus resale) gives the true economic cost of the cash purchase compared to keeping the money invested and leasing instead.

Example

Worked example: $30,000 vehicle over 36 months

Example: $30,000 vehicle, 36-month comparison

Cash: $30,000 paid upfront, 55% resale ($16,500), 5% opportunity cost on $30k over 3 years ($4,729). Lease: $1,200 drive-off, $329/mo × 36 months, $395 disposition fee.

Cash total = $30,000 $16,500 + $4,729
= $18,229
Lease total = $1,200 + ($329 × 36) + $395
= $1,200 + $11,844 + $395
= $13,439
$4,790
When opportunity cost of capital is included at 5%, leasing saves approximately $4,790 over three years versus paying cash — though cash leaves you with an owned asset.
Quick reference

3-year total cost: lease vs. cash by vehicle price

The table below compares net 3-year costs across three vehicle price points. Cash scenario assumes 55% resale value and 5% annual opportunity cost. Lease scenario assumes $1,200 drive-off, a payment equal to roughly 1.1% of vehicle price per month, and a $395 disposition fee.

Practical tips

Tips for the lease vs. cash decision

The opportunity cost argument often surprises people. Keeping $30,000–$50,000 liquid and invested can genuinely offset the cost of leasing — but only if you actually invest the difference. Here's what else to weigh.

  • Only invest the freed capital if you actually will — The opportunity cost calculation only works in the lease column if the cash you don't spend on the car is genuinely invested. If it would sit in a checking account earning 0.01%, the math reverses.
  • Business owners gain from lease deductibility — Self-employed drivers can deduct the business-use percentage of lease payments on Schedule C. Cash buyers must depreciate the vehicle over five to seven years under MACRS, which typically yields a smaller annual deduction.
  • Cash eliminates all interest and finance risk — Paying cash means no monthly obligation. In a job loss or income disruption, a paid-off car is never at risk of repossession — unlike a leased vehicle where missed payments trigger a return.
  • High-value cars favor cash if resale is strong — Luxury and performance vehicles often retain value exceptionally well (70%+ at three years for some models), making the cash net cost very competitive and eliminating lease mileage penalties.
  • Check whether your state taxes leases favorably — Several states (e.g., Texas, Illinois) tax the full purchase price on a cash buy but only the monthly payments on a lease, potentially saving $1,000–$3,000 over the lease term.
Accuracy & limits

Accuracy and limitations

The opportunity cost rate you choose has an outsized effect on the result. At 3% (high-yield savings), leasing loses much of its mathematical edge. At 7–10% (long-run equity returns), leasing wins decisively. Use a rate that honestly reflects how you would invest the cash, not an optimistic projection.

Resale value is estimated at the time of calculation and subject to market conditions. The used-car market surge of 2021–2023 pushed resale values far above historical norms for many segments, dramatically improving the economics of buying with cash. This model does not predict future market shifts. For the most accurate residuals, check Kelley Blue Book, Edmunds, or NADA Guides for your specific make, model, and trim.

Glossary

Lease vs. cash terms defined

The investment return you forgo by spending cash on a vehicle instead of investing it. Calculated as the compound growth on the purchase amount over the hold period at your expected rate of return.
All amounts due at lease signing — first month, acquisition fee, security deposit, taxes, and registration. Lower drive-off preserves more cash for investment.
A charge of $300–$500 assessed at lease end if you do not purchase the vehicle or re-lease from the same brand. Adds to the true cost of leasing.
The market value of a purchased vehicle at the end of the ownership period. Recovering a high percentage of the original purchase price is the primary financial advantage of buying with cash.
A fee (typically $595–$995) charged by the leasing company at the start of a lease to cover administrative and origination costs. Usually rolled into drive-off.
The interest rate component of a lease payment, expressed as a small decimal. Multiply by 2,400 to approximate the equivalent APR. Zero-percent APR promotions often appear as MF 0.00000.
The IRS Modified Accelerated Cost Recovery System — the method used to depreciate a purchased vehicle for business tax purposes over a five- to seven-year schedule, often less favorable than deducting lease payments directly.

Questions

Frequently asked questions about the free lease vs cash calculator

A lease vs cash calculator is a free online tool that helps you compare leasing against buying outright with cash (or buying then financing). Same comparison logic as buy-vs-lease — adjust the buy-side inputs to model a cash purchase (0 down, 0 APR). It runs entirely in your browser with instant results and no sign-up.
The base payment uses principal + APR. Sales tax can be added via the input. Doc fees, registration, and destination charges aren't included — add them to the principal.
Your new lender pays off the old loan and issues a new one in its place. The savings come from a lower rate or longer term. A longer term lowers monthly but raises total interest.
No — these are estimates for planning. Actual loan terms depend on credit score, lender, and current rates. Always read the disclosure (TILA box) before signing.
