Two lease agreements, the same vehicle, the same term—and yet the monthly lease payments are different. The reason rarely lies in the margin, but rather in the calculation method: Residual-value leasing is based on a projected vehicle value, while mileage-based leasing is based on an agreed-upon mileage limit.
Anyone who wants to lease a vehicle must therefore decide which model is right for their own use—for leasing companies, that same choice determines what data is needed for calculations and the contract, as well as which processes are relevant at the end of the lease term. The CarWise Group maps both models within a single system using LeaseWise.

A Comparison of Two Costing Methods
In a residual value lease, the leasing company determines a calculated residual value for the vehicle at the end of the lease when the contract is signed, and this value is set as a binding term in the lease agreement. The monthly lease payment is calculated as the difference between the purchase price and this projected residual value, spread out over the term of the lease in equal installments. Thus, the expected depreciation of the vehicle plays a central role in the calculation.
If the actual market value differs at the end of the term, the lessee is generally responsible for the difference: If the residual value is lower than projected, this results in an additional payment; if it is higher, part of the difference is refunded. For the leasing company, the accuracy of the monthly payment therefore depends on a precise residual value forecast: vehicle type, features, market trends, and historical resale data are all taken into account.
With mileage-based leasing, this projection is not used. Instead, a fixed mileage limit is agreed upon for the entire term of the contract, and the monthly lease payment is calculated based on the expected mileage, not on a projected residual value.
The residual value risk is borne entirely by the leasing company. If the actual mileage differs from the agreed-upon mileage, a final adjustment is made upon return: excess mileage is billed at a rate specified in the lease agreement—which is usually higher—while mileage below the agreed-upon amount is credited at a lower rate.
From an operational standpoint, this shifts the focus from market monitoring to ongoing mileage tracking throughout the entire term.
In LeaseWise’s calculation module , both methods—residual value parameters and mileage rates—can be configured and automatically reconciled with the actual values at the end of the contract.
Both Leasing Models at a Glance
A direct comparison shows how the two models differ when it comes to leasing:
| Criterion | Residual value leasing | Kilometer Leasing |
|---|---|---|
| Basis for Calculation | Projected Residual Value | Agreed Mileage |
| Residual Value Risk | Primarily for the lessee | With the lessor |
| Final Settlement at the End of the Contract | Difference from Market Value | Difference from the distance traveled |
| Predictability for the Lessee | Depending on market trends | High, provided that the kilometer limit is observed |
| Requirements for the Leasing Company | Accurate Residual Value Forecast | Real-Time Kilometer Tracking |
The difference is most evident in the event of early termination
The specific calculation method becomes particularly relevant in the event of early termination of the contract. In the case of a residual value lease, the leasing company must recalculate the residual value valid at the time of termination and compare it with the current market value in order to correctly calculate the buyout amount—a calculation step that, in addition to the monthly payments already made, requires a new market value appraisal.
With mileage-based leasing, on the other hand, it is sufficient to compare the mileage driven up to that point with the originally agreed-upon mileage, adjusted for the shortened lease term; the monthly payments already made remain unaffected.
As a result, the calculation of the termination fee is generally easier to understand in kilometer-based leasing. For leasing companies that handle many early terminations, a system that standardizes both calculation methods offers a significant efficiency gain compared to manual, case-by-case calculations.
Which model is best suited for which usage profile?
Three questions can help you decide which model is right for your contract term and usage:
- How consistent is the driving performance? For predictable use—such as field service with fixed routes—mileage-based leasing is usually the most predictable option, since the residual value risk lies with the lessor and there is no risk of having to make additional payments due to deviations in residual values.
- How much does usage vary among drivers or over different time periods? In cases of highly fluctuating or difficult-to-predict usage—such as with fleet vehicles—residual-value leasing may make more sense—provided the lessee is able or willing to assess and bear the market-value risk. Anyone who wants to opt for lower monthly payments at the start of the contract should factor in the risk of having to make additional payments at the end.
- How many types of contracts should be active simultaneously in the portfolio? For the leasing company, this is primarily a portfolio issue: A company that offers both models across different contract terms manages two distinct risk frameworks simultaneously—residual value projections on the one hand, and mileage tracking and billing on the other.
What this means for a leasing company’s software
Both models require different data and different processes at the end of the contract. Residual-value leasing requires continuously updated market value data for each vehicle type, while mileage-based leasing requires complete tracking of the distance driven over the entire term. Anyone who manages both types of leases in parallel without calculating them in a single system risks having to perform manual post-calculations and dealing with inconsistent return processes.
This is exactly where LeaseWise comes in: Calculations, contract creation, asset management, and recalculations for residual value and mileage-based leases are all handled within the same system, using the same vehicle and contract data. This reduces discrepancies between calculations and actual billing and allows for consistent management of both models within the same portfolio.
Frequently asked questions
Residual value leasing is calculated based on a projected vehicle value, while mileage leasing is calculated based on an agreed-upon mileage limit. Risk: In residual value leasing, the risk lies primarily with the lessee; in mileage leasing, it lies with the lessor.
This depends on mileage and changes in market value. If the mileage agreement is adhered to, mileage-based leasing is usually easier to plan.
The lessee pays the difference between the actual residual value and the calculated residual value, usually based on a return appraisal. If the residual value turns out to be higher, a portion of the payment is refunded.
Anyone who wants to lease a vehicle and can accurately estimate their mileage will find that mileage-based leasing offers a high degree of predictability. With residual value leasing, on the other hand, changes in the vehicle’s value play a more significant role.
Based on the vehicle type, features, expected mileage, and market data. The projected depreciation affects the calculation of the lease payment. A lower estimated residual value results in a higher payment, and vice versa.
Kilometers in excess of the agreed-upon amount are billed at the agreed-upon rate; kilometers below the agreed-upon amount are usually billed at a lower rate.
