What is money factor in a car lease?

Money factor is the financing rate for a lease, similar to interest rate. Multiply money factor by 2,400 to get the approximate APR. A money factor of 0.00125 ≈ 3% APR.

What is residual value in a lease?

Residual value is the car's estimated worth at the end of the lease term, expressed as a percentage of MSRP. A higher residual value means lower monthly payments.

How do I convert lease money factor to an APR?

Multiply the money factor by 2400. For example, a money factor of 0.00208 equals roughly 5% APR (0.00208 × 2400 = 4.99%). This lets you compare a lease rate directly against a bank loan rate.

What is capitalized cost reduction?

Cap cost reduction is any upfront amount that lowers the financed (capitalized) cost of the lease — a cash down payment, trade-in equity, or manufacturer rebate. It reduces both the depreciation and finance portions, lowering your monthly payment.

Should I put money down on a lease?

Many advisers suggest minimizing the down payment on a lease. If the car is totaled or stolen early, you can lose that upfront cash since gap coverage pays the lender, not you. Rolling less into the lease keeps more cash protected.

What happens if I exceed my lease mileage limit?

You pay a per-mile overage fee at lease-end, commonly around 15 to 30 cents per mile depending on the contract. If you expect to drive more, negotiating a higher mileage allowance upfront is usually cheaper than paying overage penalties later.

Is gap insurance included in a lease?

Many leases include gap coverage, which pays the difference between what you owe and the car's value if it is totaled. Always confirm it is in your contract — if not, you may want to add it, since leased cars can owe more than they are worth early on.

Car Lease Calculator — Estimate Monthly Lease

How to use Car Lease Calculator

The car lease calculator computes your monthly lease payment from the capitalized cost, residual value, money factor and lease term. It also converts money factor to an equivalent APR and shows the total lease cost versus financing the same vehicle — giving you both numbers to make an informed lease-or-buy decision.

Enter the vehicle MSRP and negotiated cap cost (selling price).
Add any cap cost reductions (down payment, rebates).
Enter the residual value (from the dealer — a percentage of MSRP).
Enter the money factor (from the dealer quote).
Set the lease term in months and review the monthly payment.

Your data never leaves your device — 100% private processing.

How the monthly lease payment is calculated

A lease payment has two components: the depreciation fee and the finance fee. Depreciation fee = (Adjusted Cap Cost − Residual) ÷ Lease Term. Finance fee = (Adjusted Cap Cost + Residual) × Money Factor. Monthly payment = depreciation fee + finance fee + tax. Residual value is the car's projected worth at lease-end; a higher residual means less depreciation to pay and a lower monthly payment.

Money factor to APR conversion reference
Money factor	Equivalent APR	Notes
0.00083	~2%	Excellent — manufacturer subsidised
0.00125	~3%	Good rate
0.00208	~5%	Fair market rate
0.00292	~7%	Higher — check against bank financing
0.00417	~10%	Expensive — likely better to finance

Mileage limits, wear charges and lease-end options

Standard leases allow 10,000–15,000 miles per year; excess miles are charged at $0.10–$0.30 per mile. Negotiate higher mileage upfront (cheaper) rather than paying overage at return. At lease-end you can return, buyout at residual, or roll into a new lease. A buyout is worth considering if the car's market value exceeds the residual — you gain equity instantly.

Worked examples

Money factor 0.00125 → APR

Inputs: 0.00125 × 2,400

Result: ≈ 3.0% APR equivalent

$30k cap, $18k residual, 36 mo, MF 0.00125

Inputs: dep ($12,000÷36) + finance ($48,000×0.00125)

Result: $333 + $60 ≈ $393/mo before tax

5,000 miles over the limit at lease-end

Inputs: 5,000 × $0.20 per mile

Result: $1,000 overage charge
