How to use:
- Enter actual weight and dimensions
- Enter first-weight and per-kg rates
- Optionally add remote surcharge and other fees
- Click "Calculate"
Logic:
- Volumetric weight = L × W × H ÷ factor (default 6000)
- Billable weight = max(actual, volumetric)
- Cost = first-weight fee + (billable weight − first weight) × per-kg rate + surcharges
❓ Frequently Asked Questions
How is shipping cost calculated?▾
Cost = first-weight fee + extra weight × per-kg rate + surcharges. Billable weight uses the higher of actual and volumetric weight.
What volumetric factor should I use?▾
Common: 5000 (air express), 6000 (US domestic), 8000 (some carriers). Check your carrier's contract.
Why is volumetric weight higher than actual?▾
Light but bulky items are charged by volume. Example: 60×40×40 cm box → 16 kg volumetric even if it weighs 3 kg.
How do I fill first-weight and per-kg?▾
First weight is usually 1 kg. First-weight fee is the base rate (e.g., $8). Per-kg is the extra cost per additional kg.
What is a remote surcharge?▾
Some remote regions (Alaska, Hawaii, rural areas) add a surcharge — typically $5–20.
