  2. List of price index formulas - Wikipedia

    en.wikipedia.org/wiki/List_of_price_index_formulas

    It was inadequate for that purpose. In particular, if the price of any of the constituents were to fall to zero, the whole index would fall to zero. That is an extreme case; in general the formula will understate the total cost of a basket of goods (or of any subset of that basket) unless their prices all change at the same rate.

  3. Equivalent annual cost - Wikipedia

    en.wikipedia.org/wiki/Equivalent_annual_cost

    Calculating how much should be invested in an asset in order to achieve a desired result (i.e., purchasing a storage tank with a 20-year life, as opposed to one with a 5-year life, in order to achieve a similar EAC). [11] Comparing to estimated annual cost savings, in order to determine whether it makes economic sense to invest. [12]

  4. Economic cost - Wikipedia

    Shows a firm's Economic Costs in the "Short Run" - which, as defined, contains at least 1 "Fixed Cost" that cannot be changed or done away with even if the firm goes out of business (stops producing) Variable cost: Variable costs are the costs paid to the variable input.

  5. Life-cycle cost analysis - Wikipedia

    The term differs slightly from Total cost of ownership analysis (TCOA). LCCA determines the most cost-effective option to purchase, run, sustain or dispose of an object or process, and TCOA is used by managers or buyers to analyze and determine the direct and indirect cost of an item. [1] The term is used in the study of Industrial ecology (IE ...

  7. Cost estimation models - Wikipedia

    en.wikipedia.org/wiki/Cost_estimation_models

    Cost estimation models are mathematical algorithms or parametric equations used to estimate the costs of a product or project. The results of the models are typically necessary to obtain approval to proceed, and are factored into business plans, budgets, and other financial planning and tracking mechanisms.

  8. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...

  9. Average cost method - Wikipedia

    en.wikipedia.org/wiki/Average_cost_method

    The average cost is computed by dividing the total cost of goods available for sale by the total units available for sale. This gives a weighted-average unit cost that is applied to the units in the ending inventory. There are two commonly used average cost methods: Simple weighted-average cost method and perpetual weighted-average cost method. [2]
