Fixed costs are costs that do not vary with the amount of output being produced. They are costs we cannot adjust or remove in the short run. A variable cost is a cost that we can adjust in the short run. This cost varies depending on the amount of output being produced. Taken together, fixed and variable costs represent the total cost of producti...
To better understand the difference between fixed and variable costs, imagine you are a small business owner. You’ve just signed a lease to rent out a retail space where you want to operate a hair salon. The rent you owe your landlord each month is an example of a fixed cost. It is a cost that you’ll incur regardless of the number of customers you ...
The table below shows additional examples of fixed and variable costs. Notice that we associate fixed costs with fixed inputs in production. We associate variable costs with variable inputs in production. Fixed inputs in production are factors of production that we cannot adjust in the short term. The level of output a company produces does not imp...
When discussing production costs, economists distinguish between costs in the short run and costs in the long run. In the long run, all production costs become variable. Given enough time, costs that were fixed in the short run become variable costs. In the long run, all fixed costs become variable costs. Think back to the hair salon example. Suppo...
Fixed Costs as a Share of Total Costs
Earlier, we said that total production costs are a combination of fixed and variable costs (TC = FC + VC). The share—or percentage—of total costs that are fixed varies depending on the scale of production. If the quantity of goods or services is low, the bulk of total costs will be fixed costs. In the extreme case where total output is zero, a business will only have fixed costs (TC = FC when output is zero). As a business ramps up production, fixed costs usually make up a proportionally smal...

- Choice of Production Technology. A firm can perform many tasks with a range of combinations of labor and physical capital. For example, a firm can have human beings answering phones and taking messages, or it can invest in an automated voicemail system.
- Economies of Scale. Once a firm has determined the least costly production technology, it can consider the optimal scale of production, or quantity of output to produce.
- Shapes of Long-Run Average Cost Curves. While in the short run firms are limited to operating on a single average cost curve (corresponding to the level of fixed costs they have chosen), in the long run when all costs are variable, they can choose to operate on any average cost curve.
- The Size and Number of Firms in an Industry. The shape of the long-run average cost curve has implications for how many firms will compete in an industry, and whether the firms in an industry have many different sizes, or tend to be the same size.
The long-run average cost curve shows the cost of producing each quantity in the long run, when the firm can choose its level of fixed costs and thus choose which short-run average costs it desires. If the firm plans to produce in the long run at an output of Q 3 , it should make the set of investments that will lead it to locate on SRAC 3 , which allows producing q 3 at the lowest cost.
Jun 12, 2023 · The long run refers to a period of time where all factors of production and costs are variable, and the goal is to produce at the lowest cost.
Costs in the Long Run. As in the short run, costs in the long run depend on the firm’s level of output, the costs of factors, and the quantities of factors needed for each level of output. The chief difference between long- and short-run costs is there are no fixed factors in the long run. There are thus no fixed costs.

Apr 25, 2016 · There are thus no fixed costs. All costs are variable,so we do not distinguish between total variable cost and total cost in the long run: total cost is total variable cost. The long-run average cost (LRAC) curve shows the firm’s lowest cost per unit at each level of output, assuming that all factors of production are variable.
