Depreciation Estimate Calculator
Use simple straight-line arithmetic for planning only; this calculator does not select or apply a tax depreciation method.
Estimated result
Calculation summary
Planning estimate only. Calculations retain decimals; displayed money is rounded.
Understand your estimate
What these numbers mean
Use this result as a planning checkpoint, then verify the inputs and official rules that apply to you.
What these numbers mean
The result shows depreciable basis, recovery period, straight-line annual amount, first-year proration, and remaining basis.
How they were calculated
Cost and improvements increase basis, salvage value reduces it, and the result divides basis evenly across the entered years with a simple month proration.
Common mistakes
Do not use this straight-line illustration for assets requiring MACRS conventions, omit business-use allocation, or expense the same basis twice.
Important assumptions
The model assumes straight-line recovery, entered salvage value, and a simple months-in-service fraction without conventions or bonus rules.
Why an actual return may differ
MACRS class life, Section 179, bonus depreciation, listed property, improvements, dispositions, and recapture can produce very different tax results.
How this calculator works
The calculator uses only the values shown in the form. User-entered percentages, limits, recovery periods, mileage rates, and eligibility assumptions are not treated as official defaults.
Hypothetical example
Hypothetical: A hypothetical photographer enters a $6,000 asset, five-year planning period, and six months in service. Actual tax depreciation may differ. The example is not an actual taxpayer result or a promise of tax treatment.
Important limitations
This calculator does not prepare or file a return, determine legal eligibility, select accounting or depreciation methods, apply every annual limit, or calculate state-specific law. Verify current official instructions and individual facts.
