Formula & Mathematical Methodology: Inventory Holding Cost Formula

CarryingRate% = CapitalCost% + StorageCost% + InsuranceTax% + ObsolescenceShrink%
AnnualHoldingCost = AvgInventoryValue × CarryingRate%
CarryingRate% = CapitalCost% + StorageCost% + InsuranceTax% + ObsolescenceShrink%; AnnualHoldingCost = AvgInventoryValue × CarryingRate%
  • averageInventoryValue: Average on-hand inventory valuation at cost.
  • costOfCapitalWaccPct: Annual opportunity cost of capital / credit line rate (%).
  • storageWarehousingPct: Annual warehouse space, handling & climate cost (% of inventory).
  • insuranceTaxesPct: Annual cargo/property insurance & inventory taxes (%).
  • obsolescenceShrinkagePct: Annual write-offs, pilferage, damage & expiration (%).

Rounding: Internal floating-point calculations preserve full precision; currency and percentage outputs round to 2 decimal places.

Worked Example: Inventory Holding Cost Worked Example

Break down annual inventory holding cost into capital, warehousing, insurance, and obsolescence.

  1. Enter your operational, financial, or physical measurement inputs.
  2. Apply the standard domain equation: CarryingRate% = CapitalCost% + StorageCost% + InsuranceTax% + ObsolescenceShrink%; AnnualHoldingCost = AvgInventoryValue × CarryingRate%.
  3. Review the primary result, sensitivity metrics, and 3 interactive SVG graphs.
Result: Calculates Inventory Holding Cost via CarryingRate% = CapitalCost% + StorageCost% + InsuranceTax% + ObsolescenceShrink%; AnnualHoldingCost = AvgInventoryValue × CarryingRate%.

Inventory Carrying & Holding Cost Rate (% of Average Inventory Value) Calculator: inputs, method, and how to read the result

Break down annual inventory holding cost into capital, warehousing, insurance, and obsolescence.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Display Currency: Amounts are treated in the selected currency; no foreign-exchange conversion is applied.
  • Average Inventory Value: Average on-hand inventory valuation at cost.
  • Cost Of Capital Wacc Pct: Annual opportunity cost of capital / credit line rate (%).
  • Storage Warehousing Pct: Annual warehouse space, handling & climate cost (% of inventory).

What the calculation includes

With the default values shown, Annual Inventory Carrying Cost is USD 108,000.00. The calculation follows Inventory Holding Cost Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Average Inventory Value from 450,000 $ to 495,000 $ changes Annual Inventory Carrying Cost from USD 108,000.00 to USD 118,800.00. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses industry-standard APICS/ASCM supply chain, lean manufacturing, and consumer physics formulas.
  • Actual commercial freight tariffs, marketplace commissions, and utility rates vary by carrier and contract.

Scope: Global Supply Chain, Business & Consumer Standard Check the assumptions and limitations against your situation before relying on the estimate.
