How it works
Allocate depreciable cost evenly over useful life. Salvage cannot exceed cost; this is a general model, not a local tax schedule.
annual depreciation = (cost−salvage)/life

Questions and answers
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
