What is fill rate?

Fill rate is a metric that measures the percentage of customer orders that a company fills from its available inventory within a certain time frame.

The fill rate indicates the business’s ability to fully meet customer demand quickly. The fill rate is typically a percentage calculated by dividing the number of orders filled by the total number of orders received, multiplied by 100.

A higher fill rate indicates that a business is effectively managing its inventory and meeting customer demand. If a business has a lower fill rate, it suggests potential issues such as stockouts, supply chain disruptions, or inefficiencies in order fulfilment processes. 

Fill rate formula

The fill rate formula is very easy to follow. You need to gather the number of orders you’ve filled and the total number of orders before using the formula. 

Here is the fill rate formula:

Fill Rate = (Number of Orders Filled / Total Number of Orders) * 100

How to calculate fill rate

To calculate the fill rate, follow these steps:

• Determine the total number of customer orders received within a specific time period. Let's say your business received 500 customer orders in one month.

• Calculate the number of customer orders that your company fills from available inventory within the same time period. Let's assume you were able to fulfil 450 customer orders.

• Divide the number of filled orders by the total number of orders received. In this case, the calculation would be 450 / 500 = 0.9.

• Multiply the result by 100 to express it as a percentage. In this case, the calculation would be 0.9 x 100 = 90%.

The fill rate for this specific time period would be 90%. It indicates that 90% of the customer orders received were successfully fulfilled from available inventory.

Example fill rate calculation

Let’s look at another example of how to calculate fill rate.

If a business receives 200 customer orders and can fulfil 180 of them from available inventory, the fill rate is as follows:

Fill Rate = (200 / 180) x 100 = 90%

Frequently asked questions

How do you calculate fill rate?

To calculate your fill rate, determine the total number of customer orders received within a specific time period. Then, calculate the number of customer orders that you were able to fill from available inventory during the same time period.

Finally, divide the number of filled orders by the total number of orders received, and multiply the result by 100 to express it as a percentage.

Why is fill rate important?

Fill rate is essential for businesses as it directly impacts customer satisfaction and loyalty. High fill rates indicate that a business is effectively managing its inventory, stocktaking, fulfilling orders on time, and meeting customer expectations. 

High fill rates help maintain customer trust, reduce backorders, and improve overall customer experience. Without regularly monitoring fill rates, it could take weeks to fulfil a customer’s order. 

How can businesses improve fill rate?

Businesses can improve fill rates by regularly monitoring inventory management practices, such as maintaining optimal stock levels, setting accurate reorder points, and establishing efficient replenishment processes. 

Streamlining order fulfilment operations, improving supply chain visibility, and enhancing supplier communication also help to increase fill rates.
