How it is calculated
Depreciable base = purchase price + delivery and installation − salvage value. Annual depreciation = depreciable base ÷ useful life. Same straight-line method as the general straight-line depreciation calculator, but explicitly including installation costs, which for equipment often make up a significant share of the original cost.
Under standard accounting rules, the depreciable cost usually includes every expense needed to bring the equipment to a usable state — not just the supplier's invoice price, but also delivery, installation and commissioning work.
If there's no installation cost, or it's already folded into the purchase price, enter 0 — the calculation reduces to ordinary straight-line depreciation. For the declining balance method instead of straight-line, use the separate accelerated depreciation calculator.
