Formula and assumptions

For a building held for rental throughout the selected year after its placed-in-service date. Enter the already-determined depreciable basis, excluding land and personal-use amounts. This does not choose basis, assess eligibility, model ADS, disposition, improvements, casualty adjustments or recapture. Full-year and final-year amounts are limited to the original basis.

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