A comparison of the work output from an operation to the work input to that same operation.
The efficiency equation is a comparison of the work output from an operation to the work input to that same operation. The amount of work could refer to time, effort, capacity, or more tangible items. A high level of efficiency implies a minimal amount of wasted time, effort, capacity, materials, and so forth. With a typical engine efficiency of 40%, a belt efficiency of 98% and an alternator efficiency of 55%, this leads to an overall energy conversion efficiency of only 21%. Assuming a fuel cost of $4.00/gal, this leads to an on-board electrical power cost of $0.51/kWh, or roughly 4 times a typical household utility rate. The equation for calculating the cost-effectiveness ratio is the same as that for the efficiency ratio, but the average cost per graduate is used in place of the average cost per student. EQUATION for Cost-Effectiveness Ratio. This can translate into a high level of profitability in a business. The efficiency formula is: (Work output / Work input) x 100%. The work output in this definition is considered to be the useful amount of work output-that is, all scrap, spoilage, and waste is excluded from the numerator. The efficiency formula can be used in a variety of areas, such as to examine the efficiency of motors and in quantifying energy utilization. The concept has been most thoroughly formalized in cost accounting. For example: 1  Labor efficiency variance. The variable cost per unit is plugged into the cost formula as the variable cost (VC). The fixed costs are totaled separately to calculate the Y-intercept (TFC) component of the equation. This results in a cost equation that can be used to estimate costs for future periods. Cost-effectiveness is that term. Definition. Huelsmann hülsmann defines-cost effectiveness “. . . as the most efficient way to achieve a set (goal, 2004 page).” 22, essentially it expresses a balance between attempts to keep costs to a minimum while maximising the/outcomes outputs of an educational institution or. programme
