Dimloom estimates dimensional (DIM) weight, billable weight and shipping cost for a package. Enter the size and weight, edit each carrier profile's divisor, thresholds and rounding, and paste your own rate card. A placeholder DEMO rate card shows how it works and is not any carrier's rates. It shows actual, dimensional and billable weight side by side. These are estimates only: carriers set the final billable weight, surcharges and price and can change their rules, so always confirm with your carrier. It runs in your browser and nothing you enter is uploaded. Free: the first 3 carrier profiles. An optional paid Pro upgrade adds unlimited profiles, multi-zone rate cards, batch CSV and a print report. Not affiliated with any carrier.
