HOW TO COST A PROJECT

V. Ryan © 2001-2005

 

Any company manufacturing a product or a supplier supplying goods have to calculate their costs very carefully. The cost of employing people to promote, manufacture, market and sell products should not be overlooked when you are designing a solution and you must carefully explain the costing of designs, especially when you select your best idea and develop it. There are two types of costs - ‘fixed costs’ and ‘variable costs’

   

FIXED COSTS

VARIABLE COSTS

These are costs that do not increase or decrease as output fluctuates. For example, salaries of employees, rent for premises and advertising costs.

These change as output increases and include such things as materials required to manufacture the product. If production increases then more materials are needed and consequently costs increase.
 
 

TOTAL COSTS = FIXED COSTS + VARIABLE COSTS

     

EXAMPLE - Imagine you have designed a clock and intend to produce it on a large scale (called mass production). The costs would have to be calculated in detail before you could secure a loan from a bank which would allow you to set up the business/company. The table below suggests a method of setting out the costs.

     

     

Complete the table above by filling in the total costs and unit costs.

UNIT COST = TOTAL COST / NUMBER PRODUCED

     

Costing a project with a view to producing it on a mass production line is an aspect of design work and you must present this as part of the development section of the design process. Having decided which of your ideas is the best, ‘cost’ its’ manufacture.
