Leverage historical data to transform your shipping budget from a guess into a precise forecast.
The Forecasting Challenge in Logistics
For businesses of all sizes, unpredictable shipping expenses disrupt financial planning. Relying on static averages or rough estimates often leads to budget overruns and reactive cost management. The key to stability lies in your existing data: past shipment weightcost. By applying structured analytics through a familiar tool—your spreadsheet—you can build a powerful, predictive model for your logistics budget.
The Analytical Framework: A Four-Phase Approach
1
Begin by compiling at least 12-24 months of historical shipment records. Essential data points include:
- Shipment Date:
- Actual Weight/Dim Weight:
- Total Freight Cost:
- Service Level, Origin, Destination, Carrier:

This is the core of forecasting. Use the spreadsheet's Linear RegressionLINESTSLOPE/INTERCEPT) to derive the formula for the line of best fit through your data points:

Implementation: A Practical Spreadsheet Example
| Projected Weight (lbs) (x) | Formula (Slope m = $4.2, Intercept b = $15) | Forecasted Cost (y) |
|---|---|---|
| 50 | =(4.2 * 50) + 15 | $225 |
| 120 | =(4.2 * 120) + 15 | $519 |
| 275 | =(4.2 * 275) + 15 | $1,170 |

From Data to Strategic Advantage
Moving from historical tracking to forward-looking prediction empowers proactive decision-making. This spreadsheet model provides a data-driven foundation
Start with a clean dataset, build your linear model, and iterate. Your freight budget is no longer a financial black box—it's a calculated, strategic plan.
