  2. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The cost of a solar PV module make up the largest part of the total investment costs. As per the recent analysis of Solar Power Generation Costs in Japan 2021, module unit prices fell sharply. In 2018, the average price was close to 60,000 yen/kW, but by 2021 it is estimated at 30,000 yen/kW, so cost is reduced by almost half.

  3. Cost–volume–profit analysis - Wikipedia

    en.wikipedia.org/wiki/Cost–volume–profit...

    CVP assumes the following: Constant sales price; Constant variable cost per unit;; Constant total fixed cost;; Units sold equal units produced. These are simplifying, largely linearizing assumptions, which are often implicitly assumed in elementary discussions of costs and profits.

  4. Marginal cost - Wikipedia

    en.wikipedia.org/wiki/Marginal_cost

    The first component is the per-unit or average cost. The second component is the small increase in cost due to the law of diminishing marginal returns which increases the costs of all units sold. Marginal costs can also be expressed as the cost per unit of labor divided by the marginal product of labor. [5]

  5. Levelized cost of electricity - Wikipedia

    en.wikipedia.org/wiki/Levelized_cost_of_electricity

    The cost of energy production depends on costs during the expected lifetime of the plant and the amount of energy it is expected to generate over its lifetime. The levelized cost of electricity (LCOE) is the average cost in currency per energy unit, for example, EUR per kilowatt-hour or AUD per megawatt-hour. [5]

  6. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    Average variable cost (AVC/SRAVC) (which is a short-run concept) is the variable cost (typically labor cost) per unit of output: SRAVC = wL / Q where w is the wage rate, L is the quantity of labor used, and Q is the quantity of output produced. The SRAVC curve plots the short-run average variable cost against the level of output and is ...

  7. Unit price - Wikipedia

    en.wikipedia.org/wiki/Unit_price

    In retail, unit price is the price for a single unit of measure of a product sold in more or less than the single unit. [2] The "unit price" tells you the cost per pound, quart, or other unit of weight or volume of a food package. It is usually posted on the shelf below the food. The shelf tag shows the total price (item price) and price per ...

  8. Total cost - Wikipedia

    en.wikipedia.org/wiki/Total_cost

    The additional total cost of one additional unit of production is called marginal cost. The marginal cost can also be calculated by finding the derivative of total cost or variable cost. Either of these derivatives work because the total cost includes variable cost and fixed cost, but fixed cost is a constant with a derivative of 0.

  9. Economic order quantity - Wikipedia

    en.wikipedia.org/wiki/Economic_order_quantity

    Total Cost = purchase cost or production cost + ordering cost + holding cost Where: Purchase cost: This is the variable cost of goods: purchase unit price × annual demand quantity. This is P × D; Ordering cost: This is the cost of placing orders: each order has a fixed cost K, and we need to order D/Q times per year. This is K × D/Q
