How does Amazon calculate my minimum capacity threshold?

Amazon uses your rolling 30-day order fulfillment performance to set the minimum. The threshold is recalculated daily and reflects what you have proven you can handle.

What happens if I cannot fulfill the minimum capacity?

If your actual performance drops below the minimum threshold, it can trigger late shipment warnings, affect your delivery promise accuracy, and potentially impact your account health metrics.

What's Happening

Amazon now automatically sets minimum order handling capacity for Fulfilled by Merchant (FBM) sellers. You can increase your capacity above this minimum, but you can no longer decrease it below what Amazon calculates. This change removes manual control over capacity floors and directly impacts your delivery promise accuracy. Check SKU-level results rather than relying only on account totals.

The feature rolled out in early 2025 for US sellers and has since expanded globally. Amazon uses your historical order data to determine the minimum capacity threshold, recalculating it on a rolling basis. If your actual performance drops below the threshold, it can trigger late shipment warnings and affect your account health.

How Order Handling Capacity Works Now

Your order handling capacity determines the maximum number of orders Amazon will assign to you for delivery within a specific timeframe. This directly affects the delivery promises shown to customers at checkout.

Aspect	Previous System	Current System
Minimum Setting	Seller controlled	Amazon controlled (automatic)
Maximum Setting	Seller controlled	Seller controlled (can increase)
Calculation Basis	Manual estimation	Historical performance data
Flexibility	Full control up or down	Only increase above minimum
Delivery Promises	Could be conservative	Based on proven capability

Why Amazon Made This Change

Amazon found that many sellers set artificially low capacity limits to avoid late shipment penalties. This resulted in conservative delivery promises that hurt customer experience. By setting minimums based on actual performance data, Amazon ensures delivery dates reflect what you've proven you can handle.

Who's Affected Most

High-Volume FBM Sellers

If you process hundreds of orders daily, your minimum will be set based on peak performance. This can be challenging during slower periods when staffing is reduced.

Seasonal Sellers

Sellers with seasonal spikes may find their minimums set too high for off-peak months. Your Q4 performance will set expectations Amazon applies year-round.

Multi-Channel Sellers

If you fulfill orders from other channels (Shopify, eBay) from the same warehouse, Amazon's minimum won't account for that workload. You'll need to build in buffer capacity.

Small Operations

Smaller sellers with limited staff may struggle if Amazon's minimum assumes peak capacity during vacations or unexpected absences. Late shipments can quickly damage account health.

What You Should Do Now

1.
Check Your Current Capacity Settings
Go to Seller Central → Settings → Shipping Settings → General Shipping Settings. Review your current handling capacity and compare it to your actual fulfillment capabilities.
2.
Analyze Your Late Shipment Rate
Check Account Health → Customer Service Performance → Late Shipment Rate. If you're already at risk, the automatic minimum will compound the problem. Address fulfillment bottlenecks now.
3.
Build Capacity Buffer
Plan for your capacity minimum to be based on your best 30-day performance. Ensure you can consistently meet that level, even during staff shortages or supplier delays.
4.
Consider FBA for Volume Spikes
For peak seasons, consider sending inventory to FBA to avoid capacity constraints. This lets Amazon handle fulfillment spikes without affecting your FBM metrics.
