Cost Benefit Analysis refers to a formal method that is used to help estimate or evaluate the project request for a project or proposal. This issue is itself an estimate of project and an informal approach to make a decision, whatever it is. Both definitions imply, explicitly or not, weighing the total expected costs against the total expected benefits of one or more actions to determine what action is the best or most profitable. This tool is known by the abbreviation ACB, CBA. Close to the CBA, but slightly different, formal techniques include a value analysis and measuring profitability benefits.
The process involves the calculation of initial and ongoing costs relative to expected return. It is often very difficult to construct plausible measures of costs and benefits of specific actions. In practice, analysts try to estimate the costs and benefits or by making a study, either by drawing interference with market developments. For example, a product manager may compare manufacturing costs and marketing to sales projections of a given product and make the decision only if it hopes to produce a profit that will be enough to intersect the costs ultimately. The cost-benefit analysis attempts to bring the costs and benefits on the same level. We choose a discount rate, which is then used to estimate all costs and future income related to the current value. The discount rate used for present value calculations is simply an interest rate caught financial markets.
成本效益分析是指一个正式的方法，估计是用来帮助评估项目要求的项目或建议。这个问题本身就是一个估计项目和非正式的方式作出决定，不管它是什么。这两种定义暗示，明示或对一个或多个动作的总预期收益的预计总成本，重量，以确定哪些行动是最好的或最赚钱的。这个工具是公知的缩写的ACB，CBA。关闭CBA，但略有不同，正式的技术包括价值分析和衡量盈利能力的好处。
这个过程包括初始及持续成本相对于预期回报率的计算。它往往是非常困难的具体行动的成本和收益，构建合理的措施。在实践中，分析师估计的成本和效益的一项研究，通过绘制干扰市场的发展。例如，一个产品经理可以比较的制造成本和营销进行销售预测一个给定的产品，只有当它希望产生利润，这将是相交的成本最终作出决定。成本效益分析，试图在同一水平上带来的成本和收益。我们选择的贴现率，这是当时用来估计的一切费用和未来收入的当前值。用于计算现值的折现率是一个简单的抓金融市场的利率。
