Example data table

Sample inputs and first‑year outputs for quick validation.

Scenario	Cost	Salvage	Life	Method	Qty	Annual Dep (Y1)	Monthly Dep (Y1)
Laptop pool	1,500	150	3	Straight‑Line	10	4,500	375
Headsets	120	0	2	Sum‑of‑Years	50	4,000	333.33
Scanners	400	40	4	Declining (2×)	20	4,000	333.33

Values are illustrative. Your schedule may differ by date and rounding.

Formula used

Depreciable base = Purchase cost − Salvage value.
Straight‑Line: Annual = Base ÷ Useful life.
Declining Balance: Annual = Book value × (Factor ÷ Life), limited by salvage.
Sum‑of‑Years: Annual = (Remaining life ÷ Sum of years) × Base.
Units‑of‑Use: Per‑unit = Base ÷ Total units; Annual = Units in year × Per‑unit.
As‑of accumulation: Full years + pro‑rata current year by months.
Chargeback: Monthly total ÷ Assigned employees.

Why depreciation matters for People Ops

Employee devices behave like short-cycle investments: value falls while service demand rises. Depreciation converts that drop into a predictable expense line for workforce planning, onboarding scale, and internal chargeback governance. When teams know the monthly cost of laptops, headsets, or scanners, they can forecast hiring waves and avoid surprise refresh spend.

Setting useful life and salvage assumptions

Useful life should reflect policy, warranty, and performance thresholds rather than accounting tradition alone. A three-year laptop cycle may align with security updates, while four-year monitors can remain productive. Salvage value represents expected resale, redeploy, or residual value at retirement. Consistent assumptions improve fairness across departments and strengthen audit readiness.

Comparing methods for policy and reporting

Straight-line spreads cost evenly and suits standardized fleets. Declining balance front-loads expense, matching assets that lose value faster early. Sum-of-years digits is a structured front-load option without a factor input. Units-of-use connects depreciation to utilization, helpful for shared equipment with measurable output. This calculator lets HR partners compare impacts side by side.

For internal reporting, keep the chosen method consistent within an asset class. Changing methods midstream complicates comparisons and can distort cost-per-hire metrics. If finance requires one method, HR can still model alternatives here for operational decisions during budget season reviews.

Turning depreciation into monthly chargebacks

Once yearly depreciation is known, translating it into a monthly run-rate supports cost center accountability. Multiply by quantity for pooled inventories, then divide by assigned employees to estimate a per-person charge. That figure can be used in backfills, contractor onboarding, and benefit-to-cost reviews, especially when equipment bundles differ by role.

Using schedules for replacement planning

The schedule table shows book value and accumulated depreciation by year, which helps time refresh projects. When book value approaches salvage, replace-or-redeploy decisions become clearer. Pair the schedule with headcount plans to estimate upcoming purchase volume, minimize downtime, and keep provisioning SLAs stable across growth phases and reorganizations.

Exporting CSV supports reconciliation with asset registers, while the PDF snapshot helps approvals and ticket attachments. Encourage managers to review assumptions quarterly when vendor pricing shifts or remote-work policies change. Small updates to life or salvage move monthly allocations for teams.

FAQs

Which depreciation method should we use for HR chargebacks?

Use the method your finance policy mandates for that asset class. If policy is flexible, straight-line is simplest for predictable monthly chargebacks, while utilization-based teams often prefer units-of-use for fair allocation.

How does the as‑of date affect accumulated depreciation?

The calculator sums full years and then prorates the current year by completed months between purchase and as‑of dates. This supports mid-year reporting without rebuilding the schedule manually.

Can salvage value be zero?

Yes. Set salvage to zero for items that are retired with no resale or redeploy value. The depreciable base becomes the full purchase cost, increasing annual and monthly depreciation.

What if useful life differs by department?

Keep one useful life per asset class for consistency, then document exceptions. If a team has heavier usage or compliance needs, run a separate scenario and attach the exported report to the exception request.

How should we handle pooled equipment and spares?

Enter the pool quantity and assign employees who benefit from the pool. For spares, include them if they are routinely deployed; exclude them if they stay unused and are tracked separately.

Do the exports include the schedule and key results?

Yes. The CSV includes inputs, key results, and the full year-by-year schedule. The PDF provides a compact snapshot of inputs, key results, and a trimmed schedule suitable for approvals.
