About Auto Lease Calculator
The Auto Lease Calculator estimates your monthly car lease payment from the MSRP, negotiated price, down payment, trade-in value, residual percentage, money factor, and lease term. It works out the residual (buyout) value, splits the payment into its depreciation and finance-charge components, then adds sales tax to produce a total monthly figure. It is useful when comparing dealer lease offers, checking how a higher or lower residual changes the payment, or converting a quoted interest rate into a money factor. Figures are estimates only — not financial advice — and everything runs locally in your browser, so your price and lease details are never uploaded.

Example
Input
MSRP $40k, 55% residual, MF .0025
Output
Monthly lease: ~$500
A $40,000 MSRP vehicle leased near its residual value with a 0.0025 money factor lands close to $500 a month before tax.
Common errors & troubleshooting
- Monthly payment looks far too high. — Enter the money factor as a small decimal (0.0025), not a percentage (0.25) — the Auto Lease Calculator treats the money factor field as-is, not as a percent.
- Residual value looks wrong compared to the dealer's lease sheet. — Enter the residual as a percent of MSRP (55), not a dollar amount. The Auto Lease Calculator multiplies MSRP by the residual percentage to get the residual value.
- Depreciation charge is negative. — This happens when the residual value is close to or above the negotiated price — a high residual can make the depreciation portion very small or slightly negative, which is expected on strong lease deals.
- Don't know what money factor to use. — If you only have an APR quote, divide it by 2400 to approximate the money factor (a 6% APR is close to a 0.0025 money factor).
Frequently asked questions
- What is the Auto Lease Calculator?
- It is a tool that estimates your monthly car lease payment from the MSRP, negotiated price, down payment, trade-in value, residual percentage, money factor, and lease term, split into depreciation, finance charge, and tax.
- What does the money factor mean in the Auto Lease Calculator?
- The money factor is the lease equivalent of an interest rate. It is roughly the APR divided by 2400, so a 6% APR is close to a 0.0025 money factor. The Auto Lease Calculator uses it directly to compute the monthly finance charge.
- How does the Auto Lease Calculator compute the residual value?
- It multiplies the MSRP by the residual percentage you enter (for example, 55% of a $40,000 MSRP is a $22,000 residual). This is the vehicle's projected value — and buyout price — at the end of the lease.
- Does the Auto Lease Calculator include acquisition or disposition fees?
- No. It covers price, down payment, trade-in, residual, money factor, term, and sales tax only. Add any acquisition, disposition, or dealer fees separately if you want to compare full out-of-pocket cost.
- Is the Auto Lease Calculator's monthly payment exact?
- It is an estimate based on the numbers you enter. This is a planning figure, not financial advice — your actual lease payment may differ due to lender fees, rounding, or local tax rules, so verify the final numbers with your dealer.
- Does the Auto Lease Calculator upload my vehicle or lease details?
- No. Every calculation runs locally in your browser. The price, residual, money factor, and tax figures you enter are never sent to ArrayKit or anywhere else.
