Variable operating costs + fixed operating costs = total operating costs.
Average total cost is the average of all your costs. This is your Fixed Costs and your Variable costs. Average Variable Cost is the average of your costs that can fluctuate.
Explicit costs are those that are a result of a product. Implicit costs are costs that are associated with a product, but they can't be directly linked to the product.
Avoidable or escapable costs are those costs which can be avoided by stop doing or start doing any particular activity and unavoidable costs are those costs which cannot be avoidable whether activity is done or not.For Example all variable costs are avoidable costs and fixed costs are unavoidable costs but this is general criteria to explain but not always all fixed costs are unavoidable.
Economic costs look refers to a combination of accounting costs(Explicit costs),Implicit costs and opportunity costs. Accounting costs only considers financial and costs incurred or agreed to be payed in order to produce a good or a service.
If selling costs varies with production level then selling costs are variable costs but if they remain fix then these are fixed costs.
Actual Costs are costs which have occurred and can be reliably measured. Budgeted Costs are costs which have been estimated, possibly by using Forecasted Costs.
Generally variable costs are relevant costs but if due to any decision fixed costs are also going to affected then fixed costs are also relevant costs.
(a) By time when computed historic costs standard costs (b) By financial costing Revenue costs capital costs (c) By responsibility controllable costs uncontrollable costs (d) By identification with stock product costs period costs (e) By tracing costs to end products direct costs indirect costs
Variable operating costs + fixed operating costs = total operating costs.
Not sure about the "A" but OM costs are Operational and Maintenance costs (OPEX costs).
Production costs are costs to produce
Yes normally fixed costs are period costs because these costs have to be paid no matter production done or not.
It is done so to keep control on costs as direct costs are controllable while indirect costs are not.
If marginal costs are relevant for specific situation or specific decision making scenario then marginal costs are relevant costs otherwise marginal costs can be irrelevant.
direct costs,indirect costs,sunk costs, Activity based costing.
All of these: Unit purchasing costs, Holding costs, and Ordering and setup costs.
