Fixed Asset Depreciation Excel Dashboard
FINANCIAL MODELS LAB
When does each asset stop contributing depreciation?
Use the populated dashboard to read the result, investigate its components and explore the stated decision assumptions. The workbook keeps the source figures and calculation steps available so another reviewer can trace the same selection.
See the illustrative example
Month: Oct 2026, Unit: Packaging line. The workbook opens with calculated sample figures and working financial charts. Each displayed amount belongs to its labelled selection and unit of measure.
Explore the financial questions
Depreciation allocates depreciable basis over inclusive in-service days. Period expense stops at the residual floor. A month outside the service interval contributes zero.
For each future month compute covered useful-life days/total useful-life days×depreciable basis. Sum across assets, capped at remaining basis.
Compare the observed results using each unit’s own denominator.
Move between the decision views
The analytical views include Dashboard, Driver detail, Asset life sensitivity. Start with the overview, then use the relevant driver, register or scenario view to explain a difference. Keep the reporting context consistent when comparing an amount with its source or another operating unit.
How to adapt the dashboard
Start with the short How to worksheet, which identifies the inputs, selectors and result views for this dashboard. Keep an unchanged copy of the sample before replacing its data. Enter your source values in the highlighted cells, review one reporting selection and reconcile a headline amount to your records. Change a material driver and check the result in its labelled unit. A decision assumption describes a modelled case; it does not replace the observed source figures.
Understand the calculation basis
Single straight-line asset per unit. Assumes acquisition on in-service date and no impairment, sale, revaluation or useful-life revision. Future covered dates use the existing asset start and stop dates, inclusive. The window begins after the selected cutoff plus the input delay. No life extension is assumed.
For a team review, record the selected period, operating unit, source of the inputs and the case assumptions alongside the conclusion. This context helps a colleague reproduce the result and distinguish a change in the business from a change in the modelling assumptions. The included sample is illustrative rather than company reporting.
