Diminishing Marginal Returns occur when increasing one unit of production, whilst holding other factors constant — results in lower levels of output. In other words, production starts to become less efficient. For example, a worker may produce units per hour for 40 hours. In the 41st hour, the output of the worker may drop to 90 units per hour. This is known as Diminishing Returns because the output has started to decrease or diminish.
An important aspect of diminishing marginal returns, is that output does not necessarily start to decrease. Instead, output is not increasing at such a high rate as previously. To put it another way — employing another worker does not increase output as much as it did by employing the previous worker.
So adding another worker makes the process less efficient. A company may employ an additional factor of production. This may be another machine or another employee, or some other factor. Diminishing Marginal Returns then occurs when these factors start producing fewer goods than previously. At a certain point in production, businesses start to become less productive. In economics, this is an important concept as efficiency starts to decrease at this point. Businesses may wish to stop production or re-assess its pricing strategy as the marginal cost increases.
Diminishing Returns can occur when a business needs to purchase new capital equipment or other fixed cost. For example, a manufacturer may create a new factory, but it may produce less than existing factories — therefore creating diminishing returns. At a certain point, hiring an additional worker can be counterproductive.
For example, 2 staff in a coffee house may be enough. However, a third, fourth, or fifth employee may create a chaotic environment that is inefficient. They may also start talking with each other rather than working on tables. A firm may hire an additional worker to satisfy demand, but they may not cover the full output that the employee is capable of. For example, an employee may be able to produce 10 units, but there is only demand for 5. Therefore, the employee only produces 5, resulting in diminishing returns.
We may see this in local stores which see a low footfall. On occasion, employing more people can disrupt others. For example, squeezing more workers into the same office may create an uncomfortable atmosphere. Similarly, bringing in a new piece of machinery might create unintended consequences.
For instance, it may alter the room temperate, thereby affect the quality of other products. Financial Ratios Guide to Financial Ratios. Key Takeaways The law of diminishing marginal returns states that adding an additional factor of production results in smaller increases in output.
After some optimal level of capacity utilization, the addition of any larger amounts of a factor of production will inevitably yield decreased per-unit incremental returns. For example, if a factory employs workers to manufacture its products, at some point, the company will operate at an optimal level; with all other production factors constant, adding additional workers beyond this optimal level will result in less efficient operations.

Related Terms Law of Diminishing Marginal Productivity Explains the Decay of Cost Advantages The law of diminishing marginal productivity states that input cost advantages typically diminish marginally as production levels increase.
What Is the Isoquant Curve? The isoquant curve is a graph, used in the study of microeconomics, that charts all inputs that produce a specified level of output. It is also known as a marginal value product. Demand For Labor The demand for labor describes the amount and market wage rate workers and employers settle upon at any given moment.
It follows the law of diminishing returns, eroding as output levels increase. Why Minimum Efficient Scale Matters The minimum efficient scale MES is the point on a cost curve when a company can produce its product cheaply enough to offer it at a competitive price.

Variable inputs are easier to change in a short time horizon when compared to fixed inputs. As such, returns to scale is a measure focused on changing fixed inputs and is therefore a long-term metric. Both metrics show that an increase in input will increase output up until a point, the main difference between the two is the time horizon and therefore the inputs that can be changed: variable or fixed.
Understanding both and their differences is important for firms in their decision-making process to reach optimal levels of production and cost efficiency. Financial Analysis. Financial Statements.
