What is residual value?
Residual value is the expected vehicle value at a future date and mileage. A current market valuation describes today; an RV forecast describes an uncertain future. A contractual RV is the amount a leasing provider commits to in its economics. Setting it above the eventual sale proceeds creates residual-value exposure. Keep these three values separate and agree the same sale channel, gross or net basis, condition and currency before comparing offers.
Age, mileage and model lifecycle
Depreciation is not a uniform annual deduction. Age and mileage overlap, so the model estimates mileage effects within registration-year groups before fitting a non-linear age curve. Exact generation, derivative, powertrain and transmission determine relevance. Older generations can provide a weaker proxy when the current model has little age coverage. A successor, facelift or production ending should affect a forecast only when supported by evidence or clearly entered as a scenario assumption.
Supply, demand and new-car prices
Discounted new cars may compete with used stock. Fleet registrations, rental returns and lease maturities can alter available supply. Demand can differ by country and powertrain. These drivers need dated, relevant evidence: a large collection of listings does not reveal completed sales or future demand. ChatAuto currently does not have verified registration, de-fleet or macroeconomic feeds. Enter any quantified market impact as an assumption and document its rationale; it is never silently applied as a fact.
ICE, hybrid, PHEV and BEV
Comparable curves keep powertrains separate. BEVs and PHEVs also need careful treatment of usable battery capacity, charging performance, warranty, efficiency and technological obsolescence. New-EV price competition and incentives can change an outlook, but future incentives and launches must not be invented. A measured battery SoH is different from expected SoH at return. Unknown battery health stays unknown, and an assumed monetary technology impact is explicit and editable.
Why fixed depreciation tables are weak
A fixed percentage misses differences in local markets, mileage, model age, generation changes and observed price dispersion. This tool instead anchors a robust age-and-mileage curve to a current shared valuation. Its present limitation matters: prices are observed today across different vehicle ages, not historical realized transactions. When the necessary same-country sample or mileage separation is missing, ChatAuto withholds a forecast and does not charge a question.
Downside, base and upside
The base case combines the fitted curve and entered assumptions. Downside and upside apply editable market stresses. Stress higher mileage, a 10% market fall, a six-month extension and poorer return condition separately to see which exposure matters most. A wider range and lower forecast confidence justify a larger risk buffer; they do not prove a particular loss probability. Review assumptions as new observations arrive and create a fresh, dated forecast when needed.
Contract economics and disciplined RV decisions
Subtract predicted RV from acquisition price to calculate capital depreciation and divide by the full term for average monthly depreciation. This is not a lease quote: financing, services, insurance, tax treatment and margin need separate inputs and policy. Compare market RV with the suggested risk-adjusted contract RV, inspect the source listings and assumptions, and retain the immutable forecast snapshot. Pro and Business access includes one standard question per completed forecast; viewing the result and its sensitivities uses none.
Lifecycle and mileage model
The current valuation and dated FX come from ChatAuto's shared engine. The forecast uses same-country dealer asking prices, deduplicated and matched by model, powertrain and transmission. Mileage is fitted from same-year, same-generation pairs. Robust age-group slopes then fit log(price) against log(1 + age in years), after adjusting for mileage. The resulting non-linear change is anchored to today's estimated transaction value. This is a cross-sectional lifecycle proxy, not a historical transaction model.
The uncertainty range and risk policy have not been back-tested against realized future sales. They are not a statistical confidence interval.
