Full-year educational accounting schedules. Does not implement tax depreciation, partial-year conventions or local reporting rules.

Your calculation, step by step

No black boxes
  1. Book value cannot fall below salvage.
  2. Declining balance uses the entered factor divided by life and writes the residual to salvage in the final year.

How to use this calculator

  1. Enter your own values in the labeled fields. Check the units and assumptions before comparing results. Only the fields needed for your selected calculation mode are shown.
  2. Your answer updates automatically. Review the calculation steps to see exactly how it was calculated.
  3. Copy, share, save, or download your result. Saved inputs stay on this device.

How the calculation works

Straight-line=(cost−salvage)/life; declining=book value × factor/life

All methods stop at the entered salvage value. Declining balance uses the selected factor and adjusts the final year to salvage. These are full-year educational accounting schedules; tax allowances and partial-year rules are not calculated. Review the units, period and assumptions before comparing scenarios. Displayed values are rounded, while the underlying calculation retains its available precision.

A worked example

A $10,000 asset with $1,000 salvage over 5 years has straight-line depreciation of ($10,000−$1,000)/5 = $1,800 per year.

Reading your result

Use the main result together with its units and supporting figures. Display values are rounded; calculations keep their underlying precision. A change in inputs or assumptions can change the answer. Compare the step-by-step working with your intended use before relying on an estimate.
