  2. Cigar Box method - Wikipedia

    en.wikipedia.org/wiki/Cigar_Box_method

    The Cigar Box Method is a toolkit which consists of a series of spreadsheets to help entrepreneurs, notably those in agribusiness in emerging markets, to calculate the costs of goods, margins, contribution, break-even quantity and profitability. It can be used for a single product or a complete portfolio of products.

  3. Pulse wave velocity - Wikipedia

    en.wikipedia.org/wiki/Pulse_wave_velocity

    The theory of the velocity of the transmission of the pulse through the circulation dates back to 1808 with the work of Thomas Young. [9] The relationship between pulse wave velocity (PWV) and arterial wall stiffness can be derived from Newton's second law of motion (=) applied to a small fluid element, where the force on the element equals the product of density (the mass per unit volume ...

  4. Moens–Korteweg equation - Wikipedia

    en.wikipedia.org/wiki/Moens–Korteweg_equation

    The Moens–Korteweg equation states that PWV is proportional to the square root of the incremental elastic modulus, (E inc), of the vessel wall given constant ratio of wall thickness, h, to vessel radius, r, and blood density, ρ, assuming that the artery wall is isotropic and experiences isovolumetric change with pulse pressure.

  5. Present value - Wikipedia

    en.wikipedia.org/wiki/Present_value

    The purchase price can be computed as: = [= (+)] + (+) The purchase price is equal to the bond's face value if the coupon rate is equal to the current interest rate of the market, and in this case, the bond is said to be sold 'at par'.

  6. 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.

  7. Cost–volume–profit analysis - Wikipedia

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

    When a company sells more than one type of product, the product mix (the ratio of each product to total sales) will remain constant. The components of CVP analysis are: Level or volume of activity. Unit selling prices; Variable cost per unit; Total fixed costs; Manpower Cost Direct and indirect

  8. Unit price - Wikipedia

    en.wikipedia.org/wiki/Unit_price

    A product's average price is the result of dividing the product's total sales revenue by the total units sold. When one product is sold in variants, such as bottle sizes, managers must define "comparable" units. Average prices can be calculated by weighting different unit selling prices by the percentage of unit sales (mix) for each product ...

  9. Total cost - Wikipedia

    en.wikipedia.org/wiki/Total_cost

    The long run total cost for a given output will generally be lower than the short run total cost, because the amount of capital can be chosen to be optimal for the amount of output. Other economic models use the total variable cost curve (and therefore total cost curve) to illustrate the concepts of increasing, and later diminishing, marginal ...
