What is the total principal amount? d. What is the gross margin? b. What is the total revenue? e. What is the gross margin rate? c. What is the total profit?\"crime is the difference between a product's selling price and cost as a percentage of the cost. For example. if a product sells for Php 125 and costs F'hp 100. the additional price increase is {Php 125 Php 100}! Php1] x 100 = 25%. Gross margin is the difference between a product's selling price and the cost as a percentage of revenue. For example. if a product sells for Php 125 and costs Php 100. the gross margin is {Php 125 Php 100) l Php 125 = 0.2{2D%) = 20%. Recall example 1 above. The gross margin would be {Php Q?4.4{} Php 312.000}! Php 924.400 = 0.155? = 15.62%. While the markup was 20% lntuitivelv. the markup is always larger. as compared to the gross margin. as long as you charge more than what the product costs. Markup percentage varies greatly:F depending on the industry. In some industries. the increase is a tiny percentage {5%- 1uail.) of the total cost of the product or service. while other industries mark up their products or services by an extraordinarily high amount. Therefore. there is no \"ncn'nal\" markup percentage that applies to all products. although there may be an average for a particular industry.

Let us assume that the cost of goods consists of the Php 20.000 it spends on manufacturing supplies. plus the F'hp 80.000 it pays in labor costs. Therefore. after subtracting its CUES. the company boasts Php 100.000 gross margin. The gmss margin represents the portion of each peso of revenue that the company retains as gross prot. For example. it a company's recent quarterly gross margin is 35%. that means it retains Php 0.35 from each peso of revenue generated. Because COGS have already been taken into account. those remaining funds may consequently be channeled toward paying debts. general and administrative expenses. interest fees. and dividend distributions to shareholders. Companies use gross margin to measure how their production costs relate to their revenues. For example. if a company's gross margin is falling. it may strive to slash labor costs or source cheaper suppliers of materials. Alternatively. it may decide to increase pnces. as a revenue increasing measure. Gross prot margins can also be
