// Monthly Base Storage Cost = Volume * Rate
var monthlyBaseStorage = volume * rate;
// Total Storage Cost = Monthly Base * Duration
var totalStorageCost = monthlyBaseStorage * duration;

var totalAdminFees = admin * duration;
// Grand Total = Total Storage + Total Admin + Handling (One-time)
var grandTotal = totalStorageCost + totalAdminFees + handling;
// Average Monthly Cost = Grand Total / Duration
var avgMonthlyCost = grandTotal / duration;

Understanding Warehouse Rates & Storage Costs
Calculating warehousing costs involves more than just rent. Whether you are a logistics manager seeking 3PL (Third-Party Logistics) solutions or a business owner renting industrial space, understanding the variables that affect your bottom line is crucial for accurate budgeting.
1. Pricing Models: Pallet vs. Square Footage
Warehouse rates are typically calculated using one of two primary methods:
Per Pallet: Common in 3PL environments. You are charged a specific rate for every pallet stored per month (or week). This is ideal for stackable goods and fluctuating inventory levels.
Per Square Foot: Common in lease agreements. You pay for the total floor space occupied. This is often better for unstackable items or operations that require dedicated aisles and processing areas.
2. Handling and Inbound/Outbound Fees
Storage is passive, but moving goods is active labor. "Handling" refers to the cost of receiving inventory (inbound) and shipping it out (outbound). This is usually charged as a one-time fee per pallet or per hour of labor when goods arrive or leave the facility. Our calculator treats this as a cumulative one-time cost for the duration specified.
3. Recurring Operational Expenses (OpEx)
Many warehouse contracts include Common Area Maintenance (CAM) or administrative fees. These cover shared expenses like security, lighting, pest control, and office management. Even if your storage volume decreases, these fixed monthly costs often remain constant.
How to Use This Calculator
To get an accurate estimate, input your expected storage volume (either in pallets or square feet) and the quoted base rate. Add your expected duration of storage to forecast long-term costs. Don't forget to include estimated handling fees for the movement of goods and any recurring admin fees found in your contract.
