Use the formula notes to check units, rounding and supported operations. A reference result validates the stated calculation; it does not add information that was never entered. Any limits or entertainment-only purpose are described on this page.
Formula and calculation method
Straight line=(cost−residual)/life. Double declining uses 2/life×opening book value, with a residual floor and final-year adjustment. Sum-of-years uses remaining life/sum(1..life).
