Minimum Stock Level: Definition and Explanation
A minimum stock level is a threshold value that indicates the level below which actual material stock items should not normally be allowed to fall.
In other words, a minimum stock level is a minimum quantity of a particular item of material that must be kept at all times.
The fixing of this level acts as a safety measure. For this reason, the minimum stock level is commonly known as safety stock or buffer stock.
If the actual stock falls below the minimum stock level, there is a risk of stopping production. Furthermore, management must prioritize the acquisition of fresh supplies.
The main objective of fixing the minimum stock level, and thus the minimum level of materials, is to ensure that the required quantity of each item is available at all times.
Main Factors Involved in Fixing the Minimum Stock Level
The main factors to consider when fixing the minimum stock level are:
- Average rate of consumption of materials
- Time needed to procure fresh supplies under top priority conditions
- Reorder level
- Production requirements in terms of materials
- Minimum quantity of materials that can be procured advantageously
Formula for Minimum Stock Level
The minimum stock level can be calculated by applying the following formula:
Examples
Example 1
Suppose we have the following information:
- Normal consumption = 300 units per week
- Normal delivery time = 7 weeks
- Reorder level = 2,400 units
Calculate the minimum stock level.
Solution 1
Based on this information, the minimum stock level can be calculated as follows:
Minimum Stock Level= 2,400 - (300 x 7)
= 300 units
Example 2
In a manufacturing operation, a particular material is used as follows:
- Maximum consumption = 9,000 units per week
- Minimum consumption = 3,000 units per week
- Normal consumption = 6,000 units
- Reorder level = 36,000 units
- Time required for delivery = 4 to 6 weeks
- Time required for emergent supplies: 1 week
Calculate the minimum stock level.
Solution 2
Since we know the above mentioned formula for calculating the minimum stock level, let’s start by calculating the reorder level first.
Reorder Level = Maximum Consumption per week x Maximum time required to obtain suppliers = 9,000 units x 6 weeks = 54,000 units
As the next step, we can calculate minimum stock level as follows:
Minimum Stock Level = 54,000 units - (6,000 units x 5 weeks) = 54,000 - 30,000 = 24,000 units
Note: The average time required to obtain suppliers was calculated in the following way:
= (Minimum period + Maximum Period) / 2 = 4 weeks + 6 weeks / 2 = 5 weeks

In most cases, safety stocks are necessary for companies operating with slow slow-moving. However, it may not be required for fast fast-moving.
It provides a higher level of customer service by ensuring that stocks are replenished before they fall below the minimum levels. It also reduces risk exposure to stoppages in production and sourcing problems.
Disadvantages include high costs associated with maintaining safety stocks and unnecessary storage space requirements for some levels of goods being held in inventory. Additionally, the cost of deteriorating quality of products kept in too large a quantity may exceed potential benefits from using a higher number for safety stock.
