Methods

Setup amortization, minimum lot charges, machine-hour rates, tooling cost and scrap credits.

  • Activity-based costing

    Trace resource costs through activities to products, services, and customers, with explicit drivers, capacity assumptions, and decision limits.

  • Actual costing

    Actual versus normal and standard costing, cost-pool boundaries, period-end reconciliation and an illustrative inventory-cost example.

  • Break-even quantity

    Sales volume required to cover a defined cost base, with contribution formulas, reconciled whole-unit examples, sales-mix assumptions, and capacity checks.

  • Consumable cost allocation

    Separate purchases, physical use, direct job charges, shared consumable pools, and losses before assigning costs to work.

  • Contribution margin

    Unit, total and percentage contribution; reconciliation to gross margin; and bounded examples for sales mix and constrained capacity.

  • Energy cost allocation

    Assigning electricity costs to jobs, equipment, or departments using measured consumption, tariff-specific demand, and explicit shared-cost policies.

  • Job-order costing

    Accumulate costs by identifiable job, apply overhead explicitly, and reconcile work in process, finished goods, and cost of goods sold.

  • Machine-hour rates

    Defining machine cost pools and capacity denominators, separating setup from runtime and labour, and reconciling cost recovery with selling rates.

  • Minimum lot charges

    Interpreting supplier minimum charges by lot, process, line, and invoice, with reconciled examples that distinguish billing from internal unit-cost allocation.

  • Non-recurring engineering charges

    Define NRE scope and deliverables, separate ownership from payment, and reconcile upfront charges with recovery through unit prices.

  • Process costing

    Departmental cost accumulation, equivalent units, weighted-average versus FIFO treatment, WIP valuation and process-loss boundaries.

  • Scrap recovery credits

    Estimating and reconciling the net value recovered from production scrap, with ownership, yield, settlement, and accounting boundaries.

  • Setup amortization

    Spread a defined setup cost over an explicit batch quantity while separating resource burden, supplier fees, yield, and repeated setups.

  • Standard costing

    Standard inputs allowed for actual output, reconciled material and labour variances, overhead absorption and inventory-reporting limits.

  • Tool-life cost allocation

    Assigning cutting-tool consumption and change costs to good output using usable edges, measured time in cut, and bounded reconditioning assumptions.
