4. Key Formulas & Calculation Logic

Current Book Value (3-Year Straight-Line Depreciation): =MAX(0, [@[Purchase_Cost]] - ([@[Purchase_Cost]] / 3 * (YEAR(TODAY()) - YEAR([@[Purchase_Date]]) + (MONTH(TODAY()) - MONTH([@[Purchase_Date]])) / 12)))
Total Asset Portfolio Valuation: =SUM(Table1[Current_Book_Value])
Active Deployed Asset Count: =COUNTIF(Table1[Lifecycle_Status], "Deployed")
Warranty Expiration Warning (Expiring within 60 Days): =COUNTIFS(Table1[Warranty_Expiration], ">="&TODAY(), Table1[Warranty_Expiration], "<="&TODAY()+60, Table1[Lifecycle_Status], "Deployed")
Orphaned/Unassigned Asset Audit Count: =COUNTIFS(Table1[Assigned_User], "Unassigned", Table1[Lifecycle_Status], "In Stock")

5. Summary KPI Dashboard

Metric Name	Calculation / Formula Reference	Value / Output
Total Active Assets	`=COUNTIF(Table1[Lifecycle_Status], "<>Disposed")`	`9` units
Total Portfolio CapEx	`=SUM(Table1[Purchase_Cost])`	`\$40,496.00`
Current Book Value	`=SUM(Table1[Current_Book_Value])`	`\$8,629.53`
Active Deployments	`=COUNTIF(Table1[Lifecycle_Status], "Deployed")`	`6` units
Stock / Spare Inventory	`=COUNTIF(Table1[Lifecycle_Status], "In Stock")`	`2` units
Assets in Repair	`=COUNTIF(Table1[Lifecycle_Status], "In Repair")`	`1` unit
Pending Warranties (<60 Days)	Calculated via formula rules above	`1` unit

6. Standard Operating Workflow

Procurement & Intake:
- Upon invoice approval, IT Procurement logs the record with status In Stock, assigning a system-generated Asset_ID and capturing the exact Serial_Number and Purchase_Cost.
Provisioning & Deployment:
- When assigned to an employee, update Assigned_User, Department, Location, and change Lifecycle_Status to Deployed. MDM (Intune/Jamf) agents must be verified as active.
Maintenance & Repair Operations:
- If an asset malfunctions, shift Lifecycle_Status to In Repair. If unrepairable, transition to Decommissioned and subsequently Disposed after secure data sanitization (NIST 800-88 compliance).
Audit & Reconciliation:
- On the first Monday of every month, run automated inventory scripts against Active Directory and cross-reference discrepancies against this master sheet. Verify book values match financial ledger entries.
