Leverage Formulas for Precise Control Over Total Purchase Value, Domestic Freight, and International Shipping
For importers and online arbitrage sellers, meticulous cost tracking is the foundation of profitability. Manually calculating every expense for each product unit is tedious and error-prone. The USFANS Spreadsheet
Core Formulas for Automated Calculation
1. Total Purchase Value (Product Cost)
This is the sum of the cost of all items purchased. Automation begins here.
=SUMPRODUCT(Quantity_Column, Price_Per_Unit_Column)
Example:=SUMPRODUCT(B2:B100, C2:C100). It multiplies each row's Qty by Price and sums the results.
2. Domestic Freight (to Consolidation Warehouse)
Allocate domestic shipping costs proportionally across your items.
=(Item_Weight / Total_Shipment_Weight) * Total_Domestic_Freight_Cost
Implementation:=(D2 / $D$100) * $F$1. Drag this formula down a column to apply to all items.
3. International Shipping & Duties (Landed Cost)
The most critical calculation. Combine all costs to find the true cost per unit landed in your country.
=Purchase_Value + Domestic_Freight_Allocation + (Total_Intl_Cost * (Item_Volumetric_Weight / Total_Shipment_Vol_Weight)) + (Item_Customs_Value * Duty_Rate)
Master Formula Example:=C2 + E2 + ($G$2 * (H2/$H$100)) + (C2 * 0.1). This gives you the total landed cost per item line.
Creating a Summary Dashboard
Use a separate sheet or area to summarize totals instantly:
- Grand Total Landed Cost:=SUM(Landed_Cost_Column)
- Average Cost Per Unit:=Grand_Total_Landed_Cost / SUM(Quantity_Column)
- Cost Breakdown Percentage:=SUM(Domestic_Freight_Column)
Best Practices for Implementation
- Use Absolute References ($):$G$2) to prevent errors when copying formulas.
- Keep a Constants Section:
- Data Validation:
- Automate Unit Cost:=Total_Landed_Cost_for_Line / Quantity. This is your true cost basis for pricing.
- Data Validation:
