Gold efficiency is a term that compares an item's purchase price in the ingame shop to the amount of gold that item is actually worth, based on the stats it provides. This is a form of theorycrafting within the game, but it does follow a set of guidelines that allows it to hold merit in usage within the community.

[show]Calculating Gold Efficiency
There are several basic items in League of Legends that grant just one stat. These items are used as a baseline to determine the gold value of their respective stats. Whether or not an item is gold efficient can be determined by comparing the item's ingame purchase price to its theoretical price, which is the combined gold value of all the stats the item provides. Note the theoretical price seldom takes into account any passive or active effects. However, if an item's passive is "Gain some fraction of stat X as stat Y", and the item itself gives stat X, it is customary to include the bonus to stat Y from the item's passive working on its own stats to calculate its theoretical price (for example, the Manamune).
The gold efficiency of an item is the theoretical price divided by its actual price. An item is said to be gold efficient if its gold efficiency is greater than or equal to 100%. For an item that is not gold efficient, the amount of gold its passive and/or active abilities must be worth in order to achieve gold efficiency is called its gold deficit.
The gold values assigned to stats are not measures of those stats' effectiveness. These values are simply base prices for use in determining the theoretical prices of highertier items. The goal of this page is to provide a more accurate valuation of items by measuring the worth of an item's yield (stats and abilities) in comparison to the stats a player could acquire through spending the same amount of gold on base items. In other words, how does an item with +20 AD and +20 Armor compare to buying a +20 AD item and a +20 Armor item?
An external tabular analysis of items' gold efficiencies can be found here.(Slightly outdated.)
Base Stat Prices
One way of deriving a stat's gold value is from the least expensive basic item that provides only that stat.
