Calculate working capital savings from consignment inventory by shifting holding costs to suppliers. Estimate carrying cost reduction.
Consignment inventory is a supply arrangement where the supplier retains ownership of materials stored at the manufacturer's facility until the manufacturer consumes them. The manufacturer only pays upon consumption, eliminating carrying costs and freeing working capital for the consigned items.
The financial benefit of consignment equals the carrying cost that the manufacturer would otherwise incur on the inventory. Typical carrying rates of 20-30% mean that even modest consignment programs can yield significant annual savings. However, suppliers may offset this with higher unit prices, so a total cost analysis is essential.
This calculator estimates the annual carrying cost savings from converting a portion of your inventory to consignment terms, along with the net benefit after accounting for any price premium the supplier charges.
Quantifying this parameter enables systematic comparison across time periods, shifts, and production lines, revealing patterns that might otherwise go unnoticed in routine operations. This analytical approach aligns with lean manufacturing principles by replacing waste-generating guesswork with efficient, fact-based processes that directly support value creation and cost reduction.
Consignment shifts the financial burden of inventory to the supplier while keeping material available at your facility. Understanding the carrying cost savings helps you evaluate consignment proposals and negotiate fair price premiums with suppliers. Data-driven tracking enables proactive decision-making rather than reactive problem-solving, ultimately saving time, materials, and labor costs in production operations.
Gross Savings = Consignment Inventory Value × Carrying Rate % Premium Cost = Annual Consumption Value × Price Premium % Net Savings = Gross Savings − Premium Cost
Result: $85,000 net annual savings
Gross savings = $500,000 × 25% = $125,000. Premium cost = $2,000,000 × 2% = $40,000. Net savings = $125,000 − $40,000 = $85,000 per year.
A well-drafted consignment agreement covers ownership transfer triggers, pricing and payment terms, insurance and liability, physical inventory reconciliation procedures, minimum and maximum stock levels, and termination conditions. Both parties must agree on how consumption is reported.
Consignment improves the buyer's balance sheet by reducing inventory and accounts payable. Cash flow improves because payment is deferred until consumption. For the supplier, receivables and inventory on the buyer's balance sheet increase, but the stronger relationship and volume commitment often outweigh the cost.
Consignment is less effective for low-value items (savings too small to justify administrative complexity), highly custom materials (supplier can't resell if buyer doesn't consume), or where the supplier's price premium exceeds the carrying cost benefit.
Consignment inventory is material owned by the supplier but stored at the buyer's location. The buyer pays only when they consume the material, transferring the carrying cost to the supplier.
Typically the supplier bears obsolescence risk since they own the inventory. However, this should be explicitly addressed in the consignment agreement, especially for custom or engineered materials.
Suppliers agree because consignment provides guaranteed floor space, demand visibility, and often a longer-term contract commitment. The higher per-unit price compensates for the additional carrying cost.
VMI (Vendor Managed Inventory) is a replenishment model where the supplier decides what and when to ship. Consignment is an ownership model. They are often combined but are independent concepts.
High-value items with steady demand and reliable suppliers are ideal. The carrying cost savings are largest for high-value items, and steady demand makes the arrangement predictable for the supplier.
Most ERP systems support a consignment stock type that tracks quantities without recording a financial liability until consumption. The inventory appears on the supplier's balance sheet, not yours.
