Retail basics and retail maths for everyone
Understanding Retail: Calculations & Jargon

It can sometimes feel like retailers talk a different language with so much terminology and jargon to understand, and when you add all the calculations into the mix, things get tougher still. 

To help, we have developed a comprehensive retail jargon buster together with a series of retail maths videos for all the key calculations. 

If you are new to retail they can teach you all you need to know, but also you can rely on them as a quick reference tool to jog your mind whenever you need them.

The jargon

A comprehensive online glossary of over 300 common retail terms and acronyms together with definitions, retail calculations and examples of each.

Always on hand, with quick and easy search functionality, this glossary of terms means you will know how to understand and apply retail jargon with ease and confidence.
