Compare first. Add afterwards.
Per-package comparison prevents dense and bulky parcels from wrongly offsetting one another. Confirm rounding and minimums with your carrier.

Bulky and light
60 × 40 × 30 ÷ 5000 = 14.4 kg
Actual weight: 4 kg
14.4 kgHigher value · no rounding
Compact and dense
30 × 20 × 10 ÷ 5000 = 1.2 kg
Actual weight: 7 kg
7 kgHigher value · no rounding
14.4 + 7 = 21.4 kg
Add the higher value selected for each parcel.
Why do totals alone mislead?
Actual weights total 11 kg and dimensional weights total 15.6 kg. Choosing 15.6 kg from these totals ignores each parcel’s comparison. Under the per-package method in this example, the correct result is 21.4 kg.
Actual chargeable weight remains subject to service rules, including minimums and rounding. This tool gives a selected total under your inputs, not a promise of an invoice amount.
An assumption still unclear?
Start with a question about measurement, divisors or rounding. Confirm the actual service policy before making a shipping decision.
