How to use this tool

  1. Enter your own assumptions using a consistent currency and period.
  2. Review the scenario outputs and compare alternative inputs.
  3. Check the stated model limits before using the result in an operating plan.

Try this example

{
  "cost": 20000,
  "residual": 2000,
  "life": 6,
  "elapsed": 2
}

Accuracy and scope

Simple book-value model, not tax depreciation or jurisdiction-specific accounting advice. Assumes no impairment, additions or partial-year convention.
