What this calculator does
Create a straight-line, mid-month-convention depreciation schedule for U.S. residential rental or nonresidential real property.
How it works
The calculator evaluates annual depreciation = basis ÷ recovery years, with a half-month allowed in the placed-in-service and disposition months. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
Input query strings and outputs
Use an input name in this page’s URL as ?name=value, and join additional inputs with &. Portable shared links may instead use the compact ?ac= state parameter.
