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.
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.

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.
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.
| Vehicle Price | Cash Net Cost | Lease Total Cost | Difference |
|---|---|---|---|
| $30,000 | $18,229 | $13,439 | Lease −$4,790 |
| $40,000 | $24,305 | $17,915 | Lease −$6,390 |
| $50,000 | $30,381 | $22,390 | Lease −$7,991 |

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 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.
