Chapter 6: Business costs and revenue

Business costs

All business activity involves some kind of cost. Managers need to think about the because:
  • Whether costs are lower than revenues or not. Whether a business will make a profit or not.
  • To compare costs at different locations.
  • To help set prices.
There are two main types of costs, fixed and variable costs. Here are some types of costs:
  • Fixed costs = stay the same regardless of the amount of output. They are there regardless of whether a business has made a profit or not. Also known as overheads.
  • Variable costs = varies with the amount of goods produced. They can be classified as direct costs (directly related to a product).
  • Total costs = fixed + variable costs
Break-even charts, comparing costs with revenue
Drawing a break-even chart

Uses of break-even charts
There are other benefits from the break-even chart other than identifying the breakeven point and the maximum profit. However, they are not all reliable so there are some disadvantages as well:
  • The expected profit or loss can be calculated at any level of output.
  • The impacts of business decisions can be seen by redrawing the graph.
  • The breakeven chart show the safety margin which is the amount by which sales exceed the breakeven point.
  • The graph assumes that all goods produced are sold.
  • Fixed costs will change if the scale of production is changed.
  • Only focuses on the breakeven point. Completely ignores other aspects of production.
  • Does not take into account discounts or increased wages, etc. and other things that vary with time.
Break-even point: the calcultion method.
It is possible to calculate the breakeven point withought having to draw the graph. We need two formulas to achieve this:
  • Selling Price - Variable Costs = Contribution
  • Break-even point = Total fixed costs/Contribution
Business costs: other definitions
There are other types of costs to be analysed that is split from fixed and variable costs:
  • Direct costs: costs that are directly related to the production of a particular product.
  • Marginal costs: how much costs will increase when a business decides to produce one more unit.
  • Indirect costs: costs not directly related to the product. They are often termed overheads.
  • Average cost per unit: total cost of production/total output
Economies and Diseconomies of scale:
Economies of scale are factors that lead to a reduction in average costs that are obtained by growth of a business. There are five economies of scale:
  • Purchasing economies: Larger capital means you get discounts when buying bulk.
  • Marketing: More money for advertising and own transportation, cutting costs.
  • Financial: Easier to borrow money froAlign Leftm banks with lower interest rates.
  • Managerial: Larger businesses can now afford specialist managers in all departments, increasing efficiency.
  • Technical: They can now buy specialised and latest equipment to cut overall production costs.
However, there are diseconomies of scale which increases average costs when a business grows:
  • Poor communication: It is more difficult to communicate in larger firms since there are so many people a message has to pass through. The managers might loose contact to customers and make wrong decisions.
  • Low morale: People work in large businesses with thousands of workers do not get much attention. They feel they are not needed this decreases morale and in turn efficiency.
  • Slower decision making: More people have to agree with a decision and communication difficulties also make decision making slower as well.
Budgets and forecasts: looking ahead
Business also needs to think ahead about the problems and opportunities that may arise in the future. There are things to try to forecast such as:
  • sales or consumer demands.
  • exchange rates appreciation or depreciation.
  • wage increases.
There are some forecasting methods:
  • Past sales could be used to calculate the trend, which could then be extended into the future.
  • Create a line of best fit for past sales and extend it for the future.
  • Panel consensus: asking a panel of experts for their opinion on what is going to happen in the future.
  • Market research.

"Budgets are plans for the future containing numerical and financial targets". Better managers will create many budgets for costs, planned revenue and profit and combine them into one single plan called the master budget.

Here are the advantages of budgets:
  • They set objectives for managers and workers to work towards, increasing their motivation.
  • They can be used to see how well a business is doing by comparing the budget with the result in the process of variance analysis. The variance is the difference between the budget and the result.
  • If workers get a say in choosing the objectives for a budget, the objectives would be more realistic since they are the ones that are going to do it and it also gives them better motivation.
  • Helps control the business and its allocation of resources/money.
All in all, budgeting in useful for:
  • reviewing past activities.
  • controlling current business activity - following objectives.
  • planning for the future.
Finished! That'll be all for today!

  26. How to calculate revenue?

    1. Revenue is the total sales buddy. As in you sold 10 units, each for 10$. Therefore your revenue is 100$. Revenue - Costs = Profits.

  27. This is honestly really helpful. I don't know how much time and effort you must've put in, but the fact that it's written so well just proves the level of hard work you must've done. I usually don't comment on stuff online but I thought this deserves it and I hope you see this and feel happy because we really appreciate this. Thanks a lot.

  28. Incredible post, you provide unique information in your blog.

  29. All businesses have individual costs. Managers need to keep proper account of each cost. However, to achieve such term many businesses provide their managers a software to error free management. This can be measured by analytics software such as PanXpan's finance summary research module.

  35. Please BEWARE of SCAM FRAUD by Economic Frauds Detection & Prevention Inc.

    Economic Frauds Scam -

    Around May 23, this year my office received a call from a representative (he refused to mention his name) from Economic Frauds Detection & Prevention Inc. telling us that someone had filed a damaging complaint against our company, although he would give no further details, and we have no knowledge of any such complaint. During the conversation, he suggested that we should make a payment of $650 and in return that they will not make the complaint public as it would damage our reputation. We told him that we would think about it, because it is a corporate matter, and we don't have the discretion to make payments for reasons like this without approval from our bosses. Up until this week, they have been calling us about it continuously. They even threatened to make our company famous with the information that they have by exaggerating the complaint and posting it publicly on their site and all over the internet. They even gave us their site name, which is, and asked us to check for ourselves what had happened to other companies that refused to settle with them in the past.
