3.3 - cost and revenue Flashcards
define costs
total expenditure a business incurs in order to run its operations. Costs are NOT price! Costs refer to the cost of production and price refers to the amount the product is sold for.
define revenue
(also known as sales revenue)it refers to the amount of money a business generates from the sale of goods and services
equation for revenue
TR=PQ
P - price per units
Q - quantity
P=TR/Q
AR=TR /Q
AR=P
define profit
it is the difference between revenue and cost (obviously , a higher Revenue and a lower cost will generate a bigger profit):
formula for profit
Pr=TR-TC
define fixed costs
the costs of production a firm has to pay regardless of how much it produces or sells. They remain fixed in the short run (where at least one factor of production does not change).
give 3 examples of fixed costs
Examples of Fixed costs are: rent, insurance, interest on loans. A firm has to pay these costs regardless of the production.
what factor effects fixed costs
Fixed cost can change, but independently on the level of production (output). For example, a landlord might increase the rent or managers being paid a higher salary.
explain variable costs
the costs of production that change in proportion with the level of production (output)or sales. Meaning that if the level of output or sales double the variable costs will also double (i.e. raw material costs will increase if a textile firm makes more curtains). They can be incurred in the short or the long run (where all factors of production are variable).
what effects variable costs
Variable costs are pegged with the quantity produced; if there is no production the firm won’t incur in variable costs.
give 3 examples of variable
sales commissions, packaging costs, energy usages costs
what are total costs
the sum of fixed costs (FC) plus the variable costs (VC)
equation for total costs
TC=FC+VC
equations for average fixed costs (AFC)
AFC=FC/Q
Q - quantity produced
FC - Fixed costs
equation for average variable costs (AVC)
AVC=VC/Q
Q= quantity produced
VC=variable costs
