Precision and calculation record

Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

Value = initial × (1 − loss rate)^years. Rate is your scenario; no make, model, mileage or market dataset is implied. Actual resale value can rise or fall differently.

Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.

Example inputs: vehicle value now = 20000, assumed annual value loss (%) = 20, years = 3. Projected resale value = 10240.

Before you use the result

Value = initial × (1 − loss rate)^years. Rate is your scenario; no make, model, mileage or market dataset is implied. Actual resale value can rise or fall differently.

Example results for vehicle value now

These examples use Assumed annual value loss (%): 20; Years: 3. They are reference calculations, not recommended settings.

Vehicle value now	Projected resale value
10000	5120
