Marginal cost is calculated by taking the change in total cost due to a change in production output. It is the additional cost incurred by producing one more unit of a product or service. For example, if a bakery produces 100 loaves of bread and it cost them $1000 to produce those loaves, the average cost per loaf is $10. If the bakery produces 101 loaves of bread, and it costs them $1015, the marginal cost is $15 ($1015 – $1000).
Now that we understand what marginal cost is let’s discuss How to calculate marginal cost.
Step 1 – Calculate variable costs
Variable costs are expenses that change based on the quantity of goods or services produced. These may include raw materials, labor costs (for hourly employees), packaging materials, and utilities. Fixed costs such as rent, insurance, and salaries don’t impact marginal costs since they don’t change with changes in output level. To calculate variable costs, add up all expenses that change with your production output.
Step 2 – Determine production output
The second step is to determine the number of goods or services that you produce in a given period for which you want to calculate marginal costs. For example, if you run a restaurant, you may choose to calculate the marginal cost for an extra meal served. If you run a manufacturing business, you may calculate the marginal cost for an additional product produced.
Step 3 – Calculate the change in total cost
Once you have your total costs for your chosen production output, calculate the cost of producing one more unit. This can be done by determining the change in total cost between producing the current output and producing one more unit. If your output is 100 units, and your total cost is $1000, and you produce 101 units, and your total cost is $1015, then the cost of producing one more unit would be the difference between the two production outputs or $15.
Step 4 – Calculate the marginal cost
Finally, to calculate the marginal cost, divide the change in total cost by the change in production output. By dividing the change in cost with the change in output (in this case, 1), we get the marginal cost. In our example, the marginal cost is $15/1= $15.
In conclusion, understanding how to calculate marginal costs is crucial for any business that wants to optimize its production processes and make informed decisions about pricing and output levels. Marginal cost can help you identify the point where producing one additional item is more expensive than the additional revenue it generates, helping you determine the optimal level of production. By following the steps outlined in this article, any business owner or manager can determine their marginal cost and make informed business decisions.
