HipoBuy: How to Forecast Monthly Shipping Costs Using the HipoBuy Spreadsheet

2026-01-18

Managing international shipping costs can be one of the most unpredictable aspects of running an e-commerce or import business. Unexpected freight charges can disrupt your budgeting and impact your profit margins. The HipoBuy Spreadsheet template offers a simple yet powerful solution: by analyzing your past shipment data, you can transform unpredictable expenses into a clear, forecastable budget.

The Problem: Unpredictable Shipping Expenses

Without a systematic approach, monthly shipping costs feel like a guessing game. Factors like fluctuating parcel weights, changing carrier rates, and varying destination zones make it difficult to plan financially. The HipoBuy method solves this by turning historical data into your most valuable planning tool.

Step-by-Step: Building Your Forecast Model

The core philosophy is straightforward: past trends can predict future costs. Here’s how to implement it using the HipoBuy Spreadsheet.

Step 1: Gather and Input Historical Data

Compile data from your last 6-12 months of shipments. In your spreadsheet, create columns for:

  • Month & Year
  • Total Number of Parcels
  • Total Freight Cost
  • Aggregate Parcel Weight
  • Primary Destination Country/Zones
This dataset forms the foundation of your analysis.

Step 2: Calculate Key Metrics

From your raw data, derive two essential metrics:

  • Average Cost per Shipment:
  • Average Cost per Unit Weight:
Tracking these averages over time reveals the true unit economics of your shipping.

Step 3: Analyze Trends and Identify Patterns

Look for correlations and patterns by asking:

  • Do costs spike in certain months (e.g., around holidays) due to volume or carrier surcharges?
  • Is there a clear relationship between total weight shipped and total cost?
  • Have new supplier or customer destinations changed your average zone cost?
Visualizing this data with simple line or bar charts within the spreadsheet can make patterns instantly clear.

Step 4: Create Your Forecast for the Next Period

Based on your analysis, project your upcoming month:

  1. Estimate Volume:
  2. Apply Your Average Metrics:
  3. Factor in Seasonality:
The result is a data-driven shipping budget
