How is this calculated?
Monthly depreciation = (cap cost - residual value) / term Money factor = APR / 2400 Monthly finance charge = (cap cost + residual value) * money factor Monthly tax = (depreciation + finance charge) * sales tax rate Monthly payment = depreciation + finance charge + tax
Example: a $42,000 MSRP vehicle negotiated to $39,500 with $2,000 down, 60% residual, 36 months, 6% APR and 7% tax has an estimated payment near $533 per month.

| Scenario | Inputs | Result | Notes |
|---|---|---|---|
| Compact SUV | $34,000 MSRP, 61% residual | $431/mo | 36 months, 6.5% APR |

What tips improve accuracy?
- Negotiate the sale price, not just the monthly payment.
- A higher residual value usually lowers the payment.
- Convert money factor to APR by multiplying by 2400.
- Keep down payments modest because leases can be totaled or stolen.
- Confirm whether tax is monthly or upfront in your jurisdiction.
- Compare total lease cost, mileage allowance and disposition fee.
