Shipping Inputs
Formula Used
1. Actual shipment weight
Actual Weight Total = Actual Weight Per Package × Package Count
2. Dimensional weight
Dimensional Weight Per Package = (Length × Width × Height) ÷ Dimensional Divisor
Dimensional Weight Total = Dimensional Weight Per Package × Package Count
3. Billable weight
Billable Weight = Higher of Actual Weight Total or Dimensional Weight Total
4. Base freight
Base Freight = Billable Weight × Base Rate Per Kg × Zone Multiplier × Service Multiplier
If this value is below the minimum charge, the calculator uses the minimum charge instead.
5. Carrier cost build-up
Gross Carrier Cost = Base Freight + Fuel + Handling + Packaging + Insurance + Duty/Tax + Other Surcharges
6. Discount and markup
Net Carrier Cost = Gross Carrier Cost − Carrier Discount
Final Shipping Quote = Net Carrier Cost + Merchant Markup
7. Free shipping rule
If order value meets or exceeds the free shipping threshold, customer charge becomes zero and the merchant absorbs the quote.

FAQs
1. Why does dimensional weight matter?
Carriers often charge for the space a parcel occupies, not only its scale weight. Large lightweight boxes may cost more because dimensional weight becomes higher than actual weight.
2. What is a dimensional divisor?
A dimensional divisor converts package volume into chargeable weight. Different carriers and service types use different divisors, so enter the value that matches your contract or courier documentation.
3. When should I use a minimum charge?
Use a minimum charge when the carrier enforces a lowest billable shipment amount. This helps small parcels avoid unrealistically low shipping totals in your checkout model.
4. Does this calculator support free shipping offers?
Yes. Enter the order value and free shipping threshold. When the order reaches the threshold, customer charge becomes zero and the merchant absorbed cost is displayed.
5. Should duty and tax be used for domestic orders?
Usually no. In this calculator, duty and tax are only applied to international shipments. Domestic scenarios keep that component at zero for cleaner estimates.
6. What does the merchant markup represent?
Merchant markup is the extra amount added over net carrier cost. It can cover packaging labor, platform overhead, risk buffer, or profit on shipping operations.
7. Why can customer charge differ from final shipping quote?
The final shipping quote is your calculated operational shipping price. Customer charge can become zero when a free shipping threshold is met, shifting the cost to the merchant.
8. Can I use this for carrier comparison?
Yes. Recalculate the same shipment using different base rates, zone assumptions, divisors, and surcharges to compare pricing structures across carriers or service levels.
