How to Use the Carrying Cost Calculator – Step-by-Step

Enter Storage, Insurance, Depreciation, and Opportunity Cost for the same period (typically annual).
Enter Total Inventory Value for that period (average on-hand is best).
Click Calculate to get Carrying Cost (%).
Use the % to benchmark locations/SKUs and prioritize reductions.

Validation: Values must be ≥ 0. Use consistent currency and period (all annual or all monthly). If using monthly figures, annualize for “annual inventory carrying cost.”

Understanding Your Carrying Cost

Once you enter your values and click Calculate, the tool shows Carrying Cost (%)—the portion of inventory value consumed by holding costs.

Why It Matters?

High carrying cost signals excess stock, slow turns, or expensive storage. Lowering it releases cash, cuts risk of obsolescence, and lifts margins.

When to Use It?

Use this calculator to:

Compare warehouses, categories, and seasons.
Set reorder policies and safety stock with cost awareness.
Evaluate the impact of clearance, consignment, or 3PL shifts.

Note: Want to optimize order quantities with carrying cost factored in? Use our EOQ (Economic Order Quantity) Calculator (link to be added).

Industry Carrying Cost Benchmarks?

Business Type / Context	Typical Carrying Cost Range (% of inventory value, annual)
Most industries (overall)	15% – 30%
Retail / eCommerce	20% – 25%
Manufacturing	30% – 40%
Electronics / High-tech	20% – 30%
3PL / Warehousing	15% – 22%

Note: Ranges vary by turnover, space costs, risk of obsolescence, and cost of capital. Use your own data for decisions.

Practical Examples

Example 1 — Mid-size warehouse

Storage: ₹1,00,000
Insurance: ₹25,000
Depreciation: ₹50,000
Opportunity Cost: ₹75,000
Total Inventory Value: ₹10,00,000
Carrying Cost: (1,00,000 + 25,000 + 50,000 + 75,000) ÷ 10,00,000 × 100 = 25%
Interpretation: You spend 25% of inventory value annually on holding costs.

Example 2 — High-rent urban facility

Storage: ₹2,40,000
Insurance: ₹40,000
Depreciation: ₹70,000
Opportunity Cost: ₹1,20,000
Total Inventory Value: ₹12,00,000
Carrying Cost: (2,40,000 + 40,000 + 70,000 + 1,20,000) ÷ 12,00,000 × 100
= 4,70,000 ÷ 12,00,000 × 100 = 39.2%
Interpretation: Elevated storage and capital costs push carrying cost near 40%—optimize space and inventory turns.

Growth Tips & Business Impact

Increase inventory turns. Tighten forecasting, reduce lead times, and accelerate replenishment cycles to lower average on-hand. (Impacts: Working capital, Margin.)
Right-size safety stock. Set service levels by ABC class, lead-time variability, and demand volatility to avoid overstock. (Impacts: Stockouts vs. holding cost balance.)
Optimize space & handling. Re-slot fast movers, use racking/vertical space, and renegotiate warehousing. (Impacts: Storage cost, Throughput.)
Reduce obsolescence risk. SKU rationalization, lifecycle pricing, and timely markdowns keep depreciation/shrinkage low. (Impacts: Write-offs, Gross margin.)
Lower cost of capital. Improve payment terms, use inventory financing wisely, and free cash via consignment/VMI. (Impacts: Opportunity cost.)
Leverage 3PLs strategically. Compare 3PL vs. in-house for space, labor, and SLAs; shift where total carrying cost drops. (Impacts: Cash flow, Flexibility.)
