Accurately predicting international shipping costs is a major challenge for global e-commerce businesses. At PinguBuy, we've developed a straightforward, data-driven method that leverages your existing shipment records to build reliable cost forecasts. Here’s how you can do it.
Step 1: Gather and Clean Your Historical Data
Start by exporting your past shipment data into a spreadsheet (e.g., Excel or Google Sheets). Essential columns should include:
- Parcel ID/Reference
- Shipping Date
- Destination Country & Postal Code
- Parcel Weight (in kg or lbs)
- Parcel Dimensions (L x W x H)
- Carrier & Service Level
- Actual Shipping Fee Paid
Clean this data by removing duplicates, correcting obvious errors, and standardizing weight and currency units.
Step 2: Identify Your Key Cost Drivers
Analyze your cleaned data to find the factors that most significantly impact cost. Typically, these are:
- Weight Brackets:
- Destination Zones:
- Dimensional Weight:(L x W x H)/Dimensional Factor
- Seasonal Trends:
- Destination Zones:
Step 3: Build a Simple Forecasting Model
Create a new sheet within your workbook to build a prediction table.
- Create Zone & Weight Matrix:
- Calculate Average Costs:AVERAGEIFS()
- Incorporate Surcharges:
- Calculate Average Costs:AVERAGEIFS()
Your matrix becomes a quick lookup tool for future shipments based on planned weight and destination.
Step 4: Implement and Refine Your Forecast
For upcoming shipments, use your lookup matrix to estimate costs. To improve accuracy:
- Track Variance:forecastedactual
- Update Regularly:
- Use Scatter Plots:
- Update Regularly:
