How this service works
Lease versus buy over the lease term: lease payment from money factor and residual, loan payment, resale equity and net cost.
Output
Returns a structured comparison including: monthly lease payment (with optional tax), monthly loan payment, residual value, resale equity if buying, total net cost of leasing vs. buying over the term, a verdict indicating which option is cheaper, a human-readable summary, and the money factor used. May also include disclaimer text and degraded-mode flags.
Example use cases
First-time leaser evaluating a deal
“I'm looking at leasing a $35,000 SUV for 36 months. The dealer quoted a residual of 52%, a money factor of 0.00180, and the loan APR if I bought would be 7.2%. No down payment and no extra fees. Can you calculate my monthly lease vs. loan payment and tell me which deal is better overall?”
High-mileage commuter comparing long-term cost
“I drive a lot so I'm considering buying instead of leasing. The car costs $48,000, I'd do a 48-month term, residual is 40%, money factor is 0.0022, loan APR is 5.9%, and I think the car will be worth about 35% of its price at the end. I'm putting $5,000 down. What's the net cost of each option?”
Tax-included lease payment breakdown
“My state charges 8.5% sales tax on each lease payment. The car is $29,500, 24-month lease, 63% residual, money factor 0.00150, and the loan APR is 6%. Can you show me the true monthly lease payment with tax and compare it to the loan payment?”
Technical details
Endpoint
GEThttps://automotive-calc.x402tookit.com/lease-vs-buy?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a side-by-side financial comparison of leasing vs. buying a specific vehicle, especially when you have the money factor and residual percentage from a dealer quote. It is the right choice when you want net cost, equity, and monthly payment for both paths in a single call. Prefer alternatives if you only need a standalone loan amortization schedule or a generic APR-to-payment converter.
Side effects
- Missing required parameters (price, termMonths, residualPercent, loanAprPercent) return a validation error
- residualPercent outside 10–90 range causes rejection
- termMonths outside 12–72 range causes rejection
- Providing neither moneyFactor nor leaseAprPercent may result in incomplete lease calculation
- loanAprPercent outside 0–30 range causes rejection
- Vehicle price of 0 or negative is rejected
