20. Production Costs Paying your workers and purchasing capital are all costs of producing goods and services. The production costs break down into four categories: –1. Fixed Cost –2. Variable Cost –3. Total costs –4. Marginal Costs

21. 1. Fixed Costs A cost that does not change, no matter how much of a good is produced – Examples include: The cost of renting/mortgage of a building, repairing equipment in a factory, property taxes, salaries of workers who run the business

22. Fixed Costs

23. 2. Variable Costs A cost that rises or falls depending on the quantity produced – Examples include: The cost of raw material, the cost of labor, utilities bill (electricity and heating/air condition)

24. Variable Costs

25. Total Costs The sum of your fixed costs plus your variable cost equals your total costs – In other words, add up everything your paying for to run your business

26. Marginal Costs The cost of producing one more unit of a good is called the marginal cost. – In the business world, will you make more money leaving BP gas station open all night or even a couple of hours later make a difference in making more money?? or…….. Will you lose money (not worth the total cost). – All business deal with this (not only how late to be open but number of workers needed and how much supplies to order)
