Volumetric Weight Calculator
Enter parcel dimensions in centimetres and actual weight in kilograms to compare volumetric and chargeable weight. Add separate groups for different parcel sizes. Set the divisor according to your carrier’s terms; the default 3000 is only a starting value. I do not calculate shipping tariffs or prices with this tool.
Your data never leaves your device: everything runs in your browser and nothing is sent to a server.
The divisor and rounding may vary by carrier. No tariff or price is calculated.

How to use it
- 1Enter width, length and height in cm.
- 2Enter actual kg and a whole-number quantity for identical parcels.
- 3Set your carrier’s divisor and add groups for different parcels.
- 4Review total volumetric weight and the sum of per-parcel chargeable weights.
Example
30 × 20 × 10 cm / 3000 = 2. For two identical parcels weighing 3 kg each, total volumetric weight is 4 and chargeable weight is 6.
Formula and limitations
- Volumetric weight = width × length × height / divisor.
- Chargeable weight per parcel = max(actual, volumetric); multiply by quantity.
- Divisors and rounding may vary by carrier; carrier-specific rounding is not applied.
