How Restock Limits Are Calculated

Amazon calculates restock limits based on your IPI score, inventory performance, and seasonal demand. Understanding these formulas helps you maximize your available capacity.

Available Capacity = Restock Limit - Current Stock - Inbound

  • Restock Limit: Maximum units Amazon allows you to have in FCs (varies by IPI score)
  • Current Stock: Units currently available for sale in FCs
  • Inbound: Units in transit or processing at FCs

Real Example: Planning Your Restock

Let's calculate restock capacity and timing for a typical product:

  • Current Stock: 280, Inbound: 150, Restock Limit: 1000
  • Daily Sales: 15, Lead Time: 14 days, Safety Stock: 7 days

Step 1: Used Capacity = 280 + 150 = 430 units (43%)
Step 2: Available to Send = 1000 - 430 = 570 units
Step 3: Days Until Stockout = 280 / 15 = 18.7 days
Step 4: Reorder Point = (14 + 7) Γ— 15 = 315 units
Step 5: Suggested Reorder = max(315 - 280, 0) = 35 units

Key Factors That Impact Restock Limits

Several variables determine your FBA restock limits:

  • IPI Score (High): Inventory Performance Index above 500 gives full access, below 450 reduces limits
  • Seasonality (High): Amazon increases limits during peak seasons (Q4)
  • Category (Medium): Some categories have specific limit rules
  • Seller Status (Medium): New sellers may have lower initial limits

What This Tool Doesn't Include

This tool provides estimates. You should also consider:

  • Restock Limit Changes: Amazon updates limits weekly based on your IPI
  • FC Processing Time: Inbound shipments can take 2-14 days to become available
  • Sales Variability: Daily sales can fluctuate due to promotions, seasonality, etc.
  • Long-Term Storage: Items stored over 365 days incur additional fees

FAQ About FBA Restock Limits

What is a good IPI score for FBA?
A score of 500 or above gives you full restock limit access. Scores between 450-499 result in reduced limits, and below 450 can significantly restrict your inventory capacity. Focus on reducing excess inventory and improving sell-through rate.
How often does Amazon update restock limits?
Restock limits are typically updated weekly on Sundays. However, during peak seasons or if your IPI score changes significantly, Amazon may adjust limits more frequently.
Can I request higher restock limits?
Yes, you can request limit increases through Seller Central. Provide evidence of strong sales performance, customer demand, and your ability to fulfill orders. Amazon reviews these requests on a case-by-case basis.
What happens if I exceed my restock limit?
Amazon will reject inbound shipments that would exceed your limit. You may also face storage restrictions or additional fees. It's important to monitor your limits and plan shipments accordingly.
How can I increase my IPI score?
Improve your IPI by reducing overstocked items (sell or remove excess inventory), increasing sell-through rate (optimize listings, run promotions), and reducing stranded inventory (fix listing issues). Amazon provides specific recommendations in Seller Central.
