How to Calculate Shipping Cost and Weight Automatically Before Final Payment
Automating the Key Calculations
1. Total Parcel Weight & Cost
Sum all item weights and add a buffer for packaging (e.g., box, filler). CSSBuy provides the actual weight and volumetric weight after rehearsal shipping, but you can estimate with a 10-15% buffer.
Formula Example:
=SUM(F2:F10) * 1.1 / 1000
2. Shipping Cost Estimation
Use CSSBuy's shipping estimator or known rates (e.g., $20 for first kg, $8 per additional kg for a specific line). The IFVLOOKUP
Basic IF Formula:
=IF(TotalKg <= 1, 20, 20 + (TotalKg - 1) * 8)
Advanced VLOOKUP:VLOOKUP
3. Grand Total
Combine item costs, domestic shipping, and international freight.
Formula Example:
=SUM(C2:C10) + SUM(G2:G10) + EstimatedShippingCost
