Gross requirements are the total quantity of a product or service needed to meet customer demand. Understanding and calculating ‘gross requirements’ are essential for ensuring that your business has the necessary inventory on hand to meet customer demand.

This blog post will discuss gross requirements and how to calculate them. We will also explore some of the factors that can impact gross requirements, such as seasonality and changes in customer demand.

What is the gross requirement?

Gross Requirements

Gross requirements are the sum of independent and dependent demand for a component before netting on-hand inventory and scheduled receipts.

The total requirement for raw materials, other components, and subassemblies required to produce a particular item is the gross requirement.

It is an additive feature of both the dependent and independent demands. It takes into account both the availability of dependent demands and independent demands.

The dependant demand is processed or unprocessed items through the production line. In contrast, independent demands come from external market factors, which dictate what will ultimately become of your finished goods once you’ve completed all processes involved in creating them.

How is it evaluated?

We calculate and fix the gross requirements even before netting the on-hand inventory or subtracting the demands based on the scheduled receipts.

The gross requirement is the minimum inventory required to keep the firm running smoothly. It does not consider the availability of raw materials in the inventory or any predetermined evaluation of scheduled receipts.

Example

The total amount of input of a thermal plant can be termed its gross requirement.

The thermal plant will measure it in tons of coal required at the end of each periodic productive cycle.

The total amount of flour required to produce, say 40 pieces of bread at a roadside food joint, would be its gross requirement.

The above is done without considering,

  1. the leftover materials from the previous month or
  2. any orders placed beforehand that are scheduled to arrive.

What is the gross material requirements formula?

Gross material requirements (GMR) calculate the minimum amount of materials required to produce a product. The calculation considers the raw materials’ weight of the finished product and the waste associated with production.
The GMR calculation is used by manufacturers to ensure they have an adequate supply of raw materials on hand and to help them plan for future production needs.

How to find gross requirements in MRP?

One way to find gross requirements in MRP is by multiplying the quantity of a product by the unit price. This will give you the total cost of the product for one unit. Then, to find the gross requirement, divide this number by the sale price to get the number of units that need to be sold to cover costs.

Why is gross requirements essential to figure out?

A firm needs to figure out its gross requirements capacity before operating. It is the amount of raw material the firm can function with at its full potential.

Based on the gross amount required, the firm can easily calculate the amount of on-hand inventory and other inventories based on rising demand.

If a company has a clear idea of the gross amount required to function, the company can cut down costs based on storage.

That gives an idea of the on-hand inventory required to avoid running a risk of massive loss due to loss of demand.

Similarly, due to loss of supply, a firm can lose out on customers if it is not stocked sufficiently for the future.

Characteristics of Gross Requirements

  1.  The gross requirement does not vary from day to day or even within two periodic productive cycles.
  2. Gross material meaning for a firm is the position it holds over the market it captures. The higher the demand is, among the customers, the more is the gross requirement of the company.
  3. The gross requirement can be increased by improving the facility, performing units, production units, and also demand for the finished product. This is where Materials requirement planning (MRP) can be implemented.

What is net requirement?

Net requirements are requirements for a product based on its gross requirements minus on-hand stock and scheduled receipt.

The difference between a gross requirement and a net requirement is as follows.

A net requirement plan adjusts for on-hand inventory and scheduled receipt at each level, whereas a gross requirement plan is a plan that shows the total demand for a product and it also shows when production should start to meet its requirements.

Most manufacturing industries are all about maintaining the balance between the gross and net requirements, also keeping in mind the on-hand inventories and scheduled receipts.

Striking a balance is very important and key to a thriving industry.

Conclusion

Gross requirements are the total number of units required by customers or retailers. The gross requirement is calculated by determining how many units were sold and adding to that amount the additional quantity needed for backorders (orders placed but not yet fulfilled).

Companies can use gross requirements to measure demand forecasting to consider both immediate needs and future potential needs from existing inventory stocks.
