How it is calculated
Value after N years = current value × (1 − decline rate ÷ 100)^N. The calculation assumes the value drops by the same percentage each year from an already-reduced base — the same mechanics as compound interest, just with a minus sign, so the value loss isn't linear: in absolute money, the first year loses more than the last.
Real depreciation rates vary a lot between vehicles and aren't captured by one universal number: it depends on make and model, mileage, the new and used car market, and often a sharper drop in the very first year of use — which is why the decline rate here is an editable field, not a constant.
This calculation is a rough estimate based on a constant rate, not a forecast of a specific market price: for an actual deal, it's better to check the value against current listings for similar vehicles of the same year and mileage.
