CSSBuy Spreadsheet: Automate Your Shipping Estimates

Managing costs for your CSSBuybefore

Why Automate Your Calculations?

Manually adding up item weights and estimating freight is tedious and prone to error. By using formulas, you can:

  • Get a real-time total estimated weight
  • See a dynamic shipping cost estimate
  • Track your budget and avoid surprises at the rehearsal packaging stage.
  • Compare different shipping lines instantly by changing variables.

Building Your Automated Spreadsheet

Here’s a breakdown of key columns and formulas for your sheet. Assume Column A holds item names, B is "Price (¥)", C is "Item Weight (g)".

Column Purpose Sample Formula / Note
D. Accumulated Weight (kg) Running total of weight converted to kilograms. =ROUND(SUM($C$2:C2)/1000, 2)
E. Estimated Vol. Weight (kg) Calculate volumetric weight if needed (L*W*H/6000). =ROUND((Length*Width*Height)/6000, 2)
F. Chargeable Weight (kg) Uses the greater of actual or volumetric weight. =MAX(D2, E2)
G. Carrier Rate Input Cell to enter your chosen carrier's price per kg (e.g., ¥120/kg). Manual Input Cell:
H. Estimated Freight Cost (¥) Calculates cost based on chargeable weight and rate. =F2 * $G$1
I. Item Cost + Freight Share (¥) Estimates total cost per item including a share of shipping. =B2 + (H2 / COUNTA($A$2:$A$100))

Key Formula In Detail

The core of your automation is the Total Estimated Cost

Total Estimated Weight (kg): =SUM(F:F)
Total Estimated Freight (¥): =SUM(F:F) * G1
Total Haul Cost (Items + Freight): =SUM(B:B) + (SUM(F:F) * G1)

As you input data, these summary figures will update automatically.
