About the Depreciation Calculator
This calculator estimates accounting depreciation using straight-line, declining balance, and sum-of-the-years’ digits methods. It returns annual depreciation, accumulated depreciation, book value, and a year-by-year schedule.
Straight line
Spreads depreciable cost evenly across the useful life.
Declining balance
Accelerates depreciation by applying a factor to the beginning book value.
Sum of years’ digits
Uses a declining fraction to recognize more depreciation earlier in the asset’s life.
How to use this calculator
Enter asset cost, salvage value, depreciation years, method, and optional partial-year convention. Review annual depreciation, accumulated depreciation, ending book value, and schedule rows.
⚠ Disclaimer: This is an educational accounting estimate. Tax depreciation, MACRS, Section 179, bonus depreciation, local rules, and accounting policies may require different treatment. Ask a qualified accountant or tax professional.
