Shipping Cost Calculator

1. 01Enter weight and dimensionsType the actual weight in kilograms and the box length, width, and height in centimeters.
2. 02Set the divisor and your rateType the volumetric divisor (often 5000 or 6000) and your own rate per kg, plus any handling fee.
3. 03Read the estimated costThe estimated cost, the chargeable weight, and the volumetric weight update as you type.

• Compare carriers you already knowPlug in each carrier’s rate and divisor to compare costs on the same box.
• Price a product listingEstimate the shipping to build into an online price.
• Check volumetric impactSee when a light but bulky box is billed on volume, not weight.

• Volumetric winsA 5 kg box of 60 x 40 x 30 cm at divisor 5000 has a volumetric weight of 14.4 kg, so it is billed on 14.4 kg.
• Actual weight winsA small dense 20 kg box has a tiny volumetric weight, so it is billed on the full 20 kg.
• Adding handlingA 10 handling fee is added on top of the weight-based cost.

Volumetric weight = (L x W x H in cm) / divisor. Chargeable weight = the greater of the actual weight and the volumetric weight. Estimated cost = chargeable weight x your rate per kg + handling fee. Every number comes from you, so the estimate is only as good as your inputs.

You enter weight (kg), dimensions (cm), a divisor, a rate per kg, and an optional handling fee. The tool returns the estimated cost, the chargeable weight, and the volumetric weight. It assumes a single package and a per-kg pricing model.

Use it to compare carriers whose rates you know, or to model a courier that prices per kg. For carriers that use zones or brackets, use your effective rate for the destination.

This tool has no live carrier rates, so it cannot tell you an exact UPS, FedEx, or DHL price; it only applies the rate you enter. Common mistakes are using the wrong divisor or mixing units. This is an educational estimate based on the numbers you enter, not financial advice or a carrier quote. Check it against your own figures before you rely on it.

The calculation runs in your browser on your device. Your numbers are never uploaded, stored, or shared, and closing the tab clears everything.

Does it use real carrier rates?

No. It has no carrier lookup. You enter your own rate per kg and divisor, so the estimate is transparent and under your control.

What is the volumetric divisor?

A number carriers use to turn box volume into a billable weight. Air freight often uses 5000 or 6000 (cm³ per kg).

What is chargeable weight?

The greater of the actual weight and the volumetric weight. Carriers bill on whichever is higher.

Why is my light box so expensive?

Because it is bulky. When the volumetric weight is higher than the actual weight, you are billed on volume.

Is my data saved?

No. Everything runs in your browser and nothing you enter is stored.
