A Factory Just Asked for Your EAU // Here's What That Means
EAU stands for Estimated Annual Usage, and it is the projected number of units you plan to order from a supplier over a 12-month period. If a factory or sourcing company has asked you for your EAU, they need this number to quote you accurately, plan material purchases, and determine whether your order volume fits their production capacity.
Getting your EAU right matters. Overestimate it, and you risk committing to volumes you can't move. Underestimate it, and you may get quoted higher unit prices or find that factories aren't interested in working with you. This guide walks you through what EAU actually means in practice, why it matters for your pricing, and how to calculate a realistic number before you start requesting quotes.
Why Factories Ask for Your EAU
When we send RFQs to factories on behalf of our clients at Cosmo Sourcing, EAU is one of the first things manufacturers ask for. There is a practical reason for this: factories use your EAU to make decisions that directly affect your quote.
Production Planning
A factory producing thousands of SKUs for dozens of clients needs to allocate machine time, labor, and floor space. Your EAU tells them how much of their capacity your project will require across the year. A buyer projecting 50,000 units annually receives a different level of attention and resource allocation than one projecting 2,000 units.
Material Procurement
Raw materials are purchased in bulk, and suppliers often have their own minimum order requirements. If you are sourcing a product that uses a custom fabric, for example, the textile mill supplying that fabric may require a minimum run of 3,000 meters. Your EAU helps the factory determine whether your annual volume justifies sourcing that material or whether they need to suggest an alternative.
Pricing Tiers
This is where EAU has the most direct impact on your bottom line. Factories price based on volume, and they typically quote at different price breaks. An EAU of 10,000 units per year might get you one price, while 50,000 gets you a meaningfully lower unit cost. The factory is not just looking at your first order; they are evaluating the total business you represent over the year.
How to Calculate Your EAU
Calculating your EAU depends on whether you have an existing product with sales history or you are launching something new.
For Existing Products
If you already sell the product, your EAU calculation is relatively straightforward. Start with your actual sales data from the past 12 months. If your business is growing, adjust upward based on your projected growth rate. If you are entering a new sales channel (adding retail distribution on top of e-commerce, for example), factor that additional volume in separately.
A simple formula: take your average monthly sales, multiply by 12, and apply a growth adjustment if applicable. If you sold an average of 800 units per month last year and expect 15% growth, your EAU would be approximately 11,000 units (800 x 12 x 1.15).
For New Product Launches
This is where it gets harder, and where we see buyers make the most mistakes. Without sales history, you are estimating, and factories know that. What they are looking for is a credible, thought-through number rather than an exact prediction.
Base your estimate on comparable products in your catalog (if you have them), market research on similar products in your category, your marketing budget, the traffic or demand you can realistically generate, and any pre-orders or commitments you already have.
Be honest with the factory. If you are launching a new product and your first order will be 2,000 units with a projected annual reorder of 8,000 to 10,000, say exactly that. Factories appreciate transparency, and it helps them quote you appropriately for both the initial run and subsequent orders.
How EAU Affects Your Pricing and MOQs
EAU and MOQ (Minimum Order Quantity) are closely related, but they are not the same thing. MOQ is the smallest order a factory will accept for a single production run. EAU is your total projected volume across the year, which might be split across multiple orders.
Why This Distinction Matters
A factory's MOQ might be 3,000 units per order. If your EAU is 12,000 units, you could place four orders of 3,000 throughout the year. The factory sees the full 12,000-unit annual relationship, which makes your account more attractive and gives you more leverage on pricing, even though each order is at the minimum.
On the other hand, if your EAU is only 3,000 units total and you plan to place a single order, the factory may still accept it, but you are unlikely to get their best pricing. You are also less likely to be prioritized if production schedules get tight.
What Happens When EAU Is Too Low
When your projected annual volume is very low, several things can happen. Factories may decline your project entirely because the volume does not justify the setup. Those that do accept may charge a premium per unit to cover their fixed costs. You may also have fewer options for customization, packaging, or material choices, since suppliers further up the chain have their own minimums.
This does not mean small-volume buyers are out of luck. It means you need to be strategic. Some factories specialize in lower-volume production, and a sourcing partner can help identify those. We frequently match clients with factories that are a better fit for their actual volume rather than pushing them toward manufacturers whose minimums they cannot realistically meet.
What to Do If You Don't Have an EAU Yet
If you are in the early stages of product sourcing and do not have a firm EAU, you still need to provide one when requesting quotes. Here is how to approach it honestly.
Start With Your First Order
Tell the factory what you plan to order initially. Then share your best projection for reorders over the following 12 months. Frame it as a range if necessary: "initial order of 3,000 units with projected annual volume of 10,000 to 15,000 based on sales performance."
Use Conservative Estimates
It is better to under-promise and over-deliver than to inflate your EAU to get a lower quote and then never hit those volumes. Factories remember, and your credibility affects how they treat you on future orders. If your actual orders consistently exceed your EAU, the factory will proactively offer better pricing because you have proven yourself as a reliable buyer.
Revisit and Update
Your EAU is not a number you set once and forget. As your sales data comes in, update your projections and share them with your factory. This is especially important if your volumes are growing, since the factory may be able to offer better terms once you have a track record. Understanding key procurement terms and how they work together will help you communicate more effectively with suppliers throughout this process.
Get Your EAU Right Before You Start Sourcing
Your EAU is one of the first things a factory evaluates when deciding whether to work with you and how to price your product. Getting it right, or at least getting it credibly close, sets the foundation for better quotes, stronger factory relationships, and a smoother sourcing process overall.
At Cosmo Sourcing, we help clients work through their EAU projections as part of our sourcing process. We know which factories are the right fit for different volume levels, and we present original quotes from 2 to 6 factories so you can compare pricing at your projected volume. Our flat-fee model means we have no incentive to push you toward higher volumes than you need. We are here to find the right factory for your actual business, not the biggest order we can broker.
