Closed-end lease: A lease structure with a stated mileage allowance and possible end-of-lease charges for excess miles, wear, damage, or disposition.

Open-end lease: A lease structure where the lease-end value matters; the difference between the contract residual and net sale proceeds can create a shortfall or surplus. [1]

Contract residual: The per-vehicle end-of-term benchmark stated in the open-end lease agreement. It is not the same as expected resale value.

Net sale proceeds: Expected gross sale value minus selling costs, such as remarketing, auction, or transport fees.

Excess-mile charge: The dollars charged for each planned mile above the closed-end included mileage allowance.

Cost per planned mile: Expected fleet cost divided by all planned fleet miles during the lease term.

Mistake: Using Expected annual miles (mi per year) as the closed-end contract limit.
Fix: Enter planned driving in Expected annual miles and copy the agreement limit into Closed-end included miles (mi per year).

Mistake: Entering 25 for Closed-end excess-mile charge ($ per mile) when the quote says 25 cents per mile.
Fix: Enter 0.25 because this field uses dollars per mile.

Mistake: Entering the same number for Open-end contract residual ($ per vehicle) and Expected gross sale value ($ per vehicle) without checking the market estimate.
Fix: Copy the contract benchmark into the residual field and use a separate expected resale estimate in the sale value field.

Mistake: Including the first monthly payment in both Closed-end upfront cash not in monthly payment ($ per vehicle) and Closed-end monthly payment ($ per vehicle).
Fix: Put only due-at-signing items not included in the recurring payment into the upfront-cash field.

Mistake: Treating a negative Open-end lease-end settlement per vehicle as an error.
Fix: A negative settlement is an expected surplus because net sale proceeds are above the contract residual.

Mistake: Comparing Fleet cost difference (open-end minus closed-end) when the quotes include different maintenance, insurance, or tax treatment.
Fix: Make the payment and upfront-cash entries use the same included items, or compare those missing costs separately.

• Results use the quote amounts entered and assume both lease options cover the same vehicles, lease term, and planned use.
• Expected gross sale value is an estimate. Actual open-end settlement can change with vehicle condition, market prices, sale timing, and actual selling costs.
• Closed-end wear or damage charges are included only when entered in Closed-end expected wear or damage charge ($ per vehicle).
• The calculator does not add taxes, registration, maintenance, insurance, fuel, electricity, tires, downtime, early termination charges, or other services unless they are already included in the quote amounts entered.
• Planned mileage is used for the closed-end excess-mile estimate. Actual charges can differ if actual mileage differs from the plan or the agreement has different mileage rules.
• A negative open-end settlement is treated as an expected surplus and reduces expected fleet cost; confirm whether the specific agreement returns that surplus to your business.

Calculation method

The calculator first converts the shared lease term from months to years, then applies each quote's per-vehicle charges across the fleet. Blank optional disposition, wear, and selling-cost fields count as $0.

term years = lease term months / 12

planned fleet miles = number of vehicles x expected annual miles x term years

For the closed-end quote, only planned miles above the contract allowance create an excess-mile charge.

closed-end planned excess miles per vehicle = greater of 0 or (expected annual miles - closed-end included miles) x term years

closed-end expected return charges per vehicle = excess miles x excess-mile charge + disposition fee + expected wear or damage charge

closed-end expected fleet cost = number of vehicles x (upfront cash + monthly payment x lease term months + return charges)

For the open-end quote, gross expected sale value is reduced by entered selling costs. The remaining net sale proceeds are compared with the contract residual.

open-end expected net sale proceeds per vehicle = expected gross sale value - open-end selling costs

open-end lease-end settlement per vehicle = open-end contract residual - net sale proceeds

open-end expected fleet cost = number of vehicles x (upfront cash + monthly payment x lease term months + lease-end settlement)

fleet cost difference = open-end expected fleet cost - closed-end expected fleet cost

cost per planned mile = expected fleet cost / planned fleet miles

Worked example

With 10 vehicles for 36 months, 15,000 planned miles per vehicle per year, and a 12,000-mile closed-end allowance, the closed-end quote has 9,000 planned excess miles per vehicle. At $0.25 per mile, plus a $350 disposition fee and $500 expected wear charge, return charges are $3,100 per vehicle. If the open-end residual is $25,000, expected gross sale value is $23,000, and selling costs are $750, the expected settlement is $2,750 owed per vehicle. Using the example quote payments, open-end fleet cost is $265,700 and closed-end fleet cost is $267,000, so the difference is -$1,300 and open-end costs less under those entries.

Calculation choices

A positive fleet cost difference means open-end costs more; a negative difference means open-end costs less. A positive open-end settlement means an expected amount owed, while a negative settlement means an expected surplus. The comparison is only fair when recurring payments and upfront cash use the same treatment for taxes, maintenance, insurance, and bundled services.
