Rental Economy
Asset Depreciation Calculator
What an asset silently costs you every month as it wears out — the expense no invoice ever shows.
Inputs
- Purchase price
- Useful life
- Residual value
How to use this calculator
- Enter the purchase price, useful life in years, and the residual (salvage) value.
- The tool spreads the cost evenly across the years, which is the straight-line method.
- Use the annual figure to set aside for replacement and to understand the asset's true yearly cost.
What each term means

- Spreading an asset's cost across the years it's used, not all at once.
- Useful life
- How many years the asset earns before it's retired.
- Residual value
- What the asset is worth at the end of its useful life.
