Camera Gear Depreciation Calculator

How the estimate works

The calculator applies a declining-balance rate to the original price for each year held, then stops at the value floor you choose. Every assumption remains visible and editable.

• A higher annual rate produces a steeper value curve.
• The floor prevents the planning estimate from falling below a percentage of the original price.
• Cost per shoot divides estimated depreciation by your estimated number of shoots.

What the result is not

It is not a live used-market quote, an appraisal, an insurance replacement value, or a tax depreciation calculation. Brand, model, condition, shutter count, demand, repairs, and local markets can move actual resale value in either direction.

Tax depreciation is separate

Business tax treatment depends on jurisdiction, tax year, use, elections, and other facts this page does not collect. U.S. taxpayers can start with IRS Publication 946 and a qualified tax professional.

The formula

For a purchase price P, annual rate r, value floor f, and years held t:

estimated value = max(P × f, P × (1 − r) ^ t)
cost per shoot  = (P − estimated value) ÷ (shoots per year × t)

The calculator starts at $1,799, 15% a year, and a 10% floor. Here is how the rate alone changes the same $1,799 body over six years:
