Types of Business Costs Explained

Cost graphEvery organisation has various daily costs and expenses that result from its trading activities.

Some of these don't change over the short to medium term whilst others increase or decrease directly as a result of production or sales changes.

A break-even analysis pinpoints when revenues equal fixed costs. Any margins above this point start to produce profits and positive cash flow.

Fixed Costs

Definition: An expense or cost that neither increases or decreases from changes in sales made or units produced.

The most common Profit and Loss items paid each month would include rent, rates and other utilities. These are the baseline costs in a business that still require paying even if sales are zero.

As you start to scale your operations and require larger premises or more staff then these foundation values will increase in steps. It's something to bear in mind when preparing future forecasts.

Examples of Fixed Costs

For standard operations, the following will not change on a daily, monthly or quarterly basis apart from small inflationary increases over time.

  • Monthly rental payments.
  • Local council business rates.
  • Office premises electricity and gas.
  • Staff salaries, pension payments and National Insurance contributions.
  • Water rates, broadband and telephone line rental.
  • Mortgage and loan repayments.
  • Vehicle leasing and maintenance.
  • Accounting and legal.
  • Most marketing and advertising.

Variable Costs

Definition: An expense that is accrued resulting from one additional sale or stock production.

Costs that vary directly from one additional sale or manufactured product are called variable costs. These mostly contribute to gross margin calculations and are directly related to generating stock or sales.

Variable Cost Examples

  • Staff salaries paid on a piecemeal or time basis.
  • Cost of goods sold or made.
  • Raw materials used for production.
  • Travel, entertainment and hotels.
  • Delivery and transportation.
  • Sales commissions and bonuses.

The above classifications will change depending on the industry of the business. For example, an Accountant would have their mortgage payments as a fixed cost whereas a buy to let landlord would see these as variable.

Calculating Break-Even Points

Your break-even point is where sales revenues less variable and fixed costs produce zero profits. The place in which the purple and green lines cross in the graphic below is this critical time. To the left of this point the business makes a loss and to the right, with more sales, then profits begin to increase.

Break-even charge

Pricing and improving margins play an important role in profitability. Although manufacturing organisations mainly use the analysis, it's applicable to any almost any business that has unit based pricing. For example:

  • Accountants and Solicitors charge by the customer account.
  • Restaurants increase their profitability with more reservations.

To produce this type of analysis use your forecasting tools and project the average revenue value for each additional customer together with their direct costs to produce a margin. Multiply the margin by the number of sales forecasts at various points to see the volume required to cover your fixed costs. At that point, you are at break-even.
