About the Invoice Shipping Calculator

Shipping on an invoice is a number somebody has to justify, and the two ways it goes wrong are charging by actual weight when the carrier charges by volumetric weight, and forgetting that in most of Europe delivery charged alongside taxable goods takes the tax rate of those goods.

This works the charge out by whichever basis you use: a flat rate, a rate per kilogram, a percentage of order value, a zone table, or a free-shipping threshold with a charge below it. It calculates volumetric weight from the dimensions and uses whichever is greater, which is what every courier actually bills on — a box of cushions weighing two kilograms is charged as fifteen.

It also shows the margin on the charge: what the carrier costs you against what you are charging, as an amount and a percentage. Shipping is one of the few lines on an invoice where the customer can check your cost, so knowing where you stand on it is worth the ten seconds.

Frequently asked questions

A carrier’s charge based on the space a parcel takes rather than its mass: length times width times height divided by a divisor, commonly 5,000 for air freight. Couriers bill on whichever is greater, actual or volumetric.
