Two cars with similar list prices can have very different monthly lease payments. The explanation lies in what each is predicted to be worth when the agreement ends.
What a lease payment actually covers
A lease charges for the portion of a car's value consumed during the term rather than for the whole vehicle.
That portion is the difference between the price at the start and the forecast value at the end, spread across the months of the agreement.
Interest on the outstanding amount is added, along with any fees, but the depreciation component is normally the largest part.
Why the forecast is the decisive number
A high predicted end value means less depreciation to charge, so the monthly payment falls even though nothing about the car's price changed.
A car costing more than a rival can therefore be cheaper to lease if it is expected to hold its value better.
This is why lease pricing frequently contradicts what a purchase price comparison would suggest.
How the prediction is made
Forecasters use historical performance of similar models, current used market conditions, expected supply and how many units the manufacturer plans to build.
Specification matters, since desirable colours, equipment and engine choices support values while unusual combinations narrow the pool of future buyers.
Anticipated regulation, fuel type expectations and the arrival of a replacement model all feed into the same estimate.
Who carries the risk
On a lease the finance company owns the vehicle and bears the difference if the forecast proves wrong, which is why it sets the figure conservatively.
Where an agreement gives the customer an option to buy at the predicted value, that option has real worth if the car turns out to be worth more.
If the car is worth less, handing it back transfers the shortfall to the finance company, which is the protection the arrangement provides.
Why mileage and condition are enforced
The forecast assumes a defined mileage and a defined standard of condition, and both assumptions are built into the payment.
Exceeding the mileage means the car is worth less than predicted, so excess mileage charges recover the difference.
Condition standards work the same way, which is why end-of-term inspections apply published criteria rather than a subjective judgement about wear.
Those criteria are published at the start of the agreement precisely so the assumption can be checked, and a customer who reads them early can have small damage repaired more cheaply than the charge levied for it.
