Shipping Cost Calculator
Estimate total shipping from weight, first-weight fee, additional fee and piece count (local & cross-border).
Input Data
Results
At a glance:Common logistics bills by 'first weight + additional weight': a fixed fee within the first weight, then additional fee per unit of excess. Formula: per-piece cost = first-weight fee + max(0, piece weight − first weight) × additional rate; total = per-piece cost × pieces. If billed on total actual weight, multiply pieces first then subtract first weight.
Formula
excess = max(0, piece weight − first weight).
per-piece cost = first-weight fee + excess × additional rate.
total = per-piece cost × pieces.
How to Use
- Enter the weight per piece.
- Enter first weight, first-weight fee and additional rate.
- Enter the piece count.
- The tool computes the total shipping.
Case Studies
3 pieces, 2.5 kg each
First weight 1 kg/$30, additional $12/kg.
excess = 2.5 − 1 = 1.5 kg; per-piece = 30 + 1.5×12 = $48.
3 pieces total = 48 × 3 = $144.
FAQ
What are 'first weight' and 'additional weight'?
First weight is a base allowance (e.g. 1 kg) charged a flat first-weight fee; the excess is billed per kg (or per 0.5 kg) as additional weight. This is the common local and cross-border billing structure.
Additional per kg or per 0.5 kg?
Varies by carrier. This tool uses per kg; if a carrier bills per 0.5 kg, convert the rate to per kg (e.g. $6/0.5kg → $12/kg) before entering.
Actual vs volumetric weight?
Most carriers bill the greater of actual weight and volumetric weight (L×W×H÷divisor). Light bulky goods (e.g. pillows) often use volumetric. This tool uses the weight you enter; convert volumetric to weight first if needed.
Does each piece pay first weight separately?
Usually yes. Each piece pays a first-weight fee, so many pieces repeat the first-weight cost. This tool uses the 'independent first weight per piece' model, matching most courier practice.
Free-shipping threshold?
Many shops offer 'free shipping above a spend' — that is a merchant promo, not carrier billing. If your order qualifies, shipping is 0; this tool only computes the base carrier fee.
Cross-border vs local differ a lot?
Yes. Cross-border (especially international) usually has higher first and additional rates, plus fuel surcharge and customs fees. This tool gives a base estimate; actual quote from the carrier applies.
