------------------------------------------------------OTHER------------

MOVEMENT = 7g
Boots of Speed: Unique passive: Enhanced movement 1 (50). 350 gold

TENACITY = 3.21(Moonflair)
Tenacity is hard to calculate due to having such low sample pool
Moonflair Spellblade: +35 tenacity, +50 ability power. 1200 gold.(who even uses this item?)
50ap=1087.5
1200-1087.5=112.5

CDR = 8.25g
Cool Down Reduction is a bit tricky, because there is no flat/only CDR item.
So we have to do the closest thing. I chose 3 items to work out, then add the results of all three items, then divide by 3.
Fiendish Codex: 10% cooldown reduction, +30 ability power, +7 mana regeneration per 5 seconds. 1125 gold.
- 30 AP = 652.5 and 7 MRegen = 420 (^_^) = 1072.5
10%cdr @ 52.5
Kindlegem: +10% cooldown reduction, +200 health. 850 gold.
- 200 HP = 520g. 850-520=330
10%cdr @ 330g
Stinger: +10% cooldown reduction, +40% attack speed. 1090 gold.
- 40% as = 1120
10% cdr @ -30g

33+5.25+(-30)=8.25

Please check my math as I am an idiot.
Also add other samples if you wish to get a better idea.

I skimmed it quickly, and the only thing I noticed that was off was AS. It should be 28g/1% or 280g/10%.
420 g = 15% AS
280 (2/3 of 420) = 10% AS

Not sure how this helps, but thank you!

It helps a lot with masteries, and planning out what items you want to buy.
ex: when I play top lane olaf vs another ad its more cost effective to get my own armor rather than trying to get armor pen to counter their armor.

I'm sure there are many other uses

Someone has a full spread sheet in Google docs somewhere...

Really, the importance of doing this math isn't exactly the example Karus just pointed out. Rather, it's to show the relative value of comparable items.

It's great at showing the value of Doran's items. For example, compare Long Sword, Ruby Crystal, Vampiric Scepter, and Doran's Blade.

Ruby Crystal tells us health is worth 2.64 gold per point of health.
Long Sword tells us damage is worth 41.50 gold per point of attack damage.
Vampiric Scepter tells us life steal is worth 45.00 gold per %point of life steal.

Yet Doran's Blade has:
80 health * 2.64 gold = 211.20 gold worth of health
10 AD * 41.50 gold = 415.00 gold worth of damage
3% LS * 45 gold = 135.00 gold worth of life steal

So Doran's Blade has 761.20 gold worth of stats, but costs us only 475 gold. We get these stats at a 37.5% discount by purchasing Doran's Blade. The cost, however, is that the Doran's items don't combine into other items, like the other items do.

So let's now do the math for a Bloodthirster, and we'll do the math for 0 stacks and fully stacked.

A Bloodthirster with 0 stacks has:
60 attack damage * 41.5 gold = 2,490.00 gold worth of attack damage
12% life steal * 45.0 gold = 540.00 gold worth of life steal
Total value of stats = 3,030 gold

A fully stacked Bloodthirster has:
100 attack damage * 41.5 gold = 4,150 gold worth of attack damage
20% life steal * 45 gold = 900 gold worth of life steal
Total value of stats = 5,050 gold

The total cost of Bloodthirster is 3,000 gold.

Now, compared to the base items (Long Sword and Vampiric Scepter), a Bloodthirster with 0 stacks is 1% more gold efficient. You'd actually be better off with 6 Doran's Blades, as you'd have the same AD, more LS, and health, and you'd save 150 gold. (Obviously the other problem here is the fact that BT takes 1 slot, 6DB takes 6 slots).

But compared to the base items, you get 5,050 gold worth of stats with a fully stack Bloodthirster, and it only costs you 3,000 total gold to build. This makes Bloodthirster 68% better than base items. And a fully stacked Bloodthirster is even more cost efficient then Doran's Blades. You pay only about 59% the value of the stats, whereas you're paying around 65% of the value of the stats with Doran's Blades.

Now as it turns out, you can do this math for every item. It can be hard to take into account the unique passives of some items like Infinity Edge, and some items like Sheen rely on base stats so will have different cost efficiencies for different champs with their passive. Other items like Rabadon's Deathcap or Atma's Impaler have actual values that fluctuate based on other items you've built, but you can still get a roundabout idea of the gold efficiency of every item.

The problem with this example involving armor pen and armor is that they do two very different things.

Comparing the gold efficiency of items is generally better when deciding between related stats. For example, what will give a better value on survivability, health or armor? What will help me do more damage, AD or Armor Pen? Perhaps I'm Ryze and I need to get a better idea on the gold efficiency of building mana versus AP, as my abilities scale to both. Maybe I'm an AD/AP champ and I want to look at the gold efficiency of building AD heavy, versus AP heavy, versus a good balance of the two.

And one finally note, it's worth comparing items...

For example, Long Sword provides 10 AD for 415 gold, so provides an AD value of 41.5 gold per 1 AD, however when we compare it to the other item with just AD on it, BF Sword, which provides 45 AD for 1650 gold, we get a very different value: 36.67 gold per 1 AD.

The same thing happens when we compare:
Ruby Crystal and Giant's Belt
Dagger and Recurve Bow
Brawler's Gloves and Cloak of Agility
Faerie Charm and Meki Pendant
Amplifying Tome, Blasting Wand, and Needlessly Large Rod
Cloth Armor and Chain Vest
Rejuvenation Bead and Regrowth Pendant
Null-Magic Mantle and Negatron Cloak

In every example, the more expensive the item, the more cost-efficient it is in terms of stats per gold.

Good additions to the thread


The importance I suggested was the important valuded by my own opinion so this comment:

Has zero grounds, but like I said previousley

I think I was trying to point out that I don't really see the point of comparing Armor to Armor penetration.

That's a tactical decision. One helps you do more damage while the other helps you survive. You need to decide which one of those two is more important at the time, and build that item, regardless of the gold efficiency.

But if you've decided that you need an item to help you sustain in lane, then you might look at and compare the gold efficiency of various items that can help you survive. These items would be: armor, magic resist, health, health regen, and life steal.

And while we can look at a chart and see that Cloth Armor gives us 1 armor per 16.67 gold, and Ruby Crystal gives us 1 health per 2.64 gold, it's ALSO to understand that Armor effects our survivability differently than Health. It's important to understand whether 18 armor from the Cloth Armor will allow us to soak more or less damage than 180 health from Ruby Crystal. In some cases it will, in some cases it won't.

Ultimately, comparing the gold efficiency of items in this sense, especially for items with completely different stats, can provide some very misleading results. Someone comparing the gold efficiency of armor and health could see that armor is about 6 times more expensive, per point, than health, and decide that building 6 Warmogs is the best option for survivability, when in reality, 2 Warmogs, 1 Thornmail, and 1 Force of Nature will give you more survivability, it's cheaper, and uses 2 fewer item slots.
