Gold efficiency

Gold efficiency is a derivative heuristic to compare item efficiency based on their stats vs price (gold cost).

Gold efficiency does not have direct gameplay implications, and is a subset of theorycrafting. Gold efficiency is most useful for comparing different items' relative, theoretical values.

The "true" value of an item cannot be easily modeled due to more complex interactions, such as named item effects, penetration effects vs armor and magic resistance, synergistic item combinations, or simply how the item interacts with the champions in a given game.

Gold Efficiency Formula

Gold efficiency is calculated as the ratio of the item's theoretical gold value to its actual in-game price.

The formula for the gold efficiency of an item as a percentage) is:

$\pagecolor {Black}\color {White}{\rm {Gold\ efficiency}}={{\rm {Gold\ value}} \over {\rm {Item\ price}}}\times 100\%$

• Gold value is the value of the items' stats based on "reference items", the cheapest items that provide a given stat.
  • If an item has passive or active effects, they are only taken into account if they provide stats with a gold value. For example, if an item's effect added a temporary flat movement speed, the gold value of this effect could be determined because there is a reference value for movement speed.
• Item price is the completed item cost from the in-game shop.
• The quotient is multiplied by 100% to convert the result to a percentage.

Basic reference items

The gold values assigned to stats are not measures of the effectiveness of those stats. They are simply base values meant to be used in determining the theoretical value of other items (or effects that are not item-related, such as Dragon buffs or Runes).

A stat's gold value is derived from the least expensive basic item that provides only that stat:

Secondary stat reference items

Not all stats have basic items that provide only that stat. This includes:

• Ability haste
• Armor penetration (flat, percent, and Lethality)
• Heal and shield power
• Life steal
• Magic penetration (flat and percent)
• Omnivamp
• On-hit damage
• Percentage-based movement speed

Item Statistics

An item is said to be gold efficient if its gold efficiency is at least 100%. Generally, items with less than 100% gold efficient have passive or active effects that are not taken into account when determining their gold value. This then results in a theoretical gold deficit in the item's value; in those cases that is compensated for by the the item's passive or active effects.

Trivia

• Spell vamp was valued at 27.5 per percentage point until Hextech Revolver's spell vamp was removed in V6.9.
• HP5 and MP5 (regen per 5 seconds) were valued at 60 and 36 respectively, prior to the regen changes in V4.20.
  • Flat HP5 is still available on Doran's Shield and Guardian's Horn.
  • Flat MP5 is still available exclusively on Guardian's Orb.
• The snowball item Mejai's Soulstealer begins with a very low gold efficiency, but upon reaching maximum stacks has one of the best possible in the game.
• Warmog's Armor and Titanic Hydra have no gold efficiency cap with Sion's Soul Furnace and Cho'Gath's Feast because they can hypothetically increase their health infinitely, which would scale their health regeneration and attack damage respectively.
• Rabadon's Deathcap and Vigilant Wardstone has no gold efficiency cap with Thresh's Damnation and Veigar's Phenomenal Evil Power.
  • Vigilant Wardstone also has no gold efficiency cap with Senna's Absolution.
