How to Calculate Order Fulfillment Rate
Order fulfillment rate is one of the most critical Key Performance Indicators (KPIs) in supply chain management, logistics, and e-commerce. It measures the efficiency of your order processing system by comparing the number of orders successfully shipped and delivered against the total number of orders received.
A high fulfillment rate indicates that your inventory management is accurate, your picking and packing processes are efficient, and your customers are receiving what they ordered. A low rate can signal issues with stockouts, backorders, or warehouse inefficiencies.
The Order Fulfillment Rate Formula
To calculate your order fulfillment rate, use the following formula:
(Total Fulfilled Orders / Total Orders Received) × 100 = Fulfillment Rate %
Where:
- Total Orders Received: The aggregate count of all orders placed by customers within a specific time frame.
- Total Fulfilled Orders: The count of orders that were successfully processed, shipped, and delivered without cancellations or stockouts.
Example Calculation
Let's say you run an online clothing store. During the month of November, you received 1,200 orders.
However, due to some inventory discrepancies, you had to cancel 20 orders, and 30 orders are currently on backorder and haven't shipped yet. This means you successfully fulfilled:
1,200 (Total) – 20 (Cancelled) – 30 (Backorder) = 1,150 Fulfilled Orders.
Using the formula:
(1,150 ÷ 1,200) × 100 = 95.83%
Your Order Fulfillment Rate for November is 95.83%.
Why is Order Fulfillment Rate Important?
Monitoring this metric helps businesses in several ways:
- Customer Satisfaction: Customers expect their orders to be processed quickly and accurately. A high fulfillment rate builds trust and loyalty.
- Inventory Accuracy: Frequent inability to fulfill orders often points to discrepancies between physical stock and system records.
- Revenue Protection: Every unfulfilled order represents potential lost revenue and the risk of losing a customer to a competitor.
What is a Good Order Fulfillment Rate?
While 100% is the ideal goal, it is not always realistic due to factors like supplier delays or sudden demand spikes. Generally, a fulfillment rate above 98% is considered excellent in most e-commerce sectors. Rates below 95% typically suggest that operational improvements are needed to prevent customer churn.
Improving Your Fulfillment Rate
To improve your metrics, consider implementing an Inventory Management System (IMS) to track stock in real-time, diversify your supplier base to avoid shortages, and optimize your warehouse layout to speed up the picking process.
function calculateFulfillmentRate() {
// 1. Get input values
var totalOrdersInput = document.getElementById('totalOrders');
var fulfilledOrdersInput = document.getElementById('fulfilledOrders');
