Meaning
Accounting methods that distribute initial capital expenditures for injection molds and stamping dies across unit piece prices allocate non-recurring engineering costs over production volumes. Tooling amortisation adds a fixed surcharge to each manufactured plastic enclosure until the total initial tooling investment is fully recovered by the supplier or buyer. The accounting mechanism ends once agreed unit volume thresholds are reached or tool recovery balances drop to zero.
Cost Allocation
Supply agreements specify exact amortisation surcharges appended to component unit costs during production runs. Under typical tooling amortisation agreements, an original equipment manufacturer pays an extra set amount per plastic housing component until the mold cost is satisfied. Procurement invoices itemize piece prices and tool recovery fees separately.
Volume Sensitivity
Financial payback timelines depend directly on factory production volumes matching forecast schedules. When sales volumes fall short of projections, tooling amortisation extends recovery periods, leaving unamortized tool balances on vendor balance sheets. Volume shortfalls may trigger contractual lump-sum settlement clauses.
Recovery Boundary
Final tool payoff shifts piece pricing down to baseline material and manufacturing costs once target production volumes pass accounting thresholds. Clear tracking of tooling amortisation guarantees that buyers cease paying capital surcharges after recovering original tooling investments.
