Your Historical Spreadsheet: A Goldmine for Prediction
Most businesses track shipping data, often in simple spreadsheets. Each row holds the secret to better forecasting:
- Parcel Dimensions:
- Route Details:
- Cost Data:
- Temporal Data:
This collected data forms the foundation for a reliable predictive model.
A Step-by-Step Forecasting Method
Step 1: Data Cleaning & Organization
Ensure your spreadsheet data is consistent. Standardize weight units (e.g., all in kilograms), currency values, and destination names. Remove any outliers or errors.
Step 2: Identify Primary Cost Drivers
Analyze your data to confirm correlations. Typically, weightdestination zone
Step 3: Build a Simple Predictive Model
For a straightforward model, calculate the average cost per kilogram
Estimated Cost = (Forecasted Parcel Weight) × (Historical Avg. Cost per Kg for Route)
Adjust for a ~5-10% buffer for carrier rate increases.
Step 4: Incorporate Seasonal Trends
Label past shipments by quarter or season. If costs consistently rose 15% in Q4 (holiday season), apply that trend to your Q4 forecasts.
Step 5: Automate & Refine
Transfer your logic to spreadsheet formulas. Use VLOOKUPXLOOKUP
Practical Example: From Past to Forecast
Imagine your Q3 spreadsheet shows five shipments to France, averaging 2kg and $18 per shipment ($9/kg). You have a planned Q4 shipment of 3kg to France.
Basic Forecast:
Seasonally Adjusted Forecast (with 10% Q4 Surcharge):$29.70.
Your budget forecast for this parcel becomes approximately $30.
