The TRUE Growth stat formula you can't seem to find anywhere else..

Lol it took me forever too figure it out The formula people keep giving me is the formula for the additional stat gain at that level, not the total amount of stats earned at that level. I'll post the true formula at the top, but if you want to understand keep reading.

B = Original Base Stat, G = Growth Stat, L = Current Level Total Base at Current Level = B + .65G(L-1) + .035G(1.5 + (.5L-.5))(L-1)

Found a nifty way to simplify that mess of a formula.. : B + G(L-1)[.65 + .035(.5L + 1)] Into finally: Total Base Stat at Current Level = B + G(L-1)(.685+.0175L) Your Welcome and good night.

Why thats different from everything i've heard so far...

Non-Linear stat formula:

StatValue = BaseValue + (GrowthValue* ((ChampionLevel*3.5) + 65)/100))

For Vi's Health we get:

Level Health Growth
1 582.8 85
2 644.0 61.2
3 708.2 64.2
4 775.3 67.2
5 845.5 70.1
6 918.6 73.1
7 994.6 76.1
8 1073.7 79.1
9 1155.7 82.0
10 1240.7 85.0
11 1328.7 88.0
12 1419.6 91.0
13 1513.6 93.9
14 1610.5 96.9
15 1710.3 99.9
16 1813.2 102.9
17 1919.0 105.8
18 2027.8 108.8

Same formula for Health, Mana, Attack Damage, HP5 and Armor.

Level	Health	Growth
1	582.8	85
2	644.0	61.2
3	708.2	64.2
4	775.3	67.2
5	845.5	70.1
6	918.6	73.1
7	994.6	76.1
8	1073.7	79.1
9	1155.7	82.0
10	1240.7	85.0
11	1328.7	88.0
12	1419.6	91.0
13	1513.6	93.9
14	1610.5	96.9
15	1710.3	99.9
16	1813.2	102.9
17	1919.0	105.8
18	2027.8	108.8

The problem with that. Vi:

Level // Health // Growth // Your Formula //////////////////// Your Formula Answer. 8 ///// 1073.7 /// 79.1 // 582.8 + (85*((83.5)+65)/100)) //// 661.85 9 ///// 1155.7 /// 82.0 // 582.8 + (85((93.5)+65)/100)) //// 664.825 10 ///// 1240.7 /// 85 /// 582.8 + (85((10*3.5)+65)/100)) /// 667.8

If you ignore the base stat add on 582.8, your only calculating the value of growth at each level, not the complete growth gained from all previous levels. The real, far more complicated formula is as follows. This formula will work for any growth stat of any champion at their current level.

B = Original Base Stat, G = Growth Stat, L = Current Level

Total Base Stat at Current Level = B + G(L-1)(.685+.0175L)

If you theorycraft it takes 2 minutes to make a automated formula in excel or some similar spreadsheet. It took me two hours of soul crushing math to work it out since I haven't done this kind of thing in a long time. I hope someone appreciates it. :)

It's been posted by Rioters and the formula is even available on the wiki.

Stats Gained Per Level

Stat advantages through levels have been smoothed out. Honestly speaking, Leona + Graves will still beat the stuffing out of you at level 2, but level advantages should be more focused on ability ranks than raw stat gains. Mana regeneration has been normalized across mages and supports to account for the new mana regeneration item changes.

Basically we're trying to smooth out level advantages through stat gains. Given how strong basic attacks and ability levels are during the early game, flat stat per-level advantages only magnify early game snowballing - especially that level 2 power spike that laners use to punch their opponents in the face.

For the attack damage change, we saw an opportunity to lightly address the minor imbalance between ranged and melee in the solo lane, so ranged champions (and Jayce / Kayle) won't have their base AD modified by the base stat buff (which rounds out to +2 AD for melee champions). There's something to be said about loss aversion, but let's not go into that.

* HOW DID WE ARRIVE AT 168%* All champions have had their base stats raised by 168% of their old per-level statistic (except attack speed) *NO SUCH THING AS LOSS AVERSION *All ranged champions (and Kayle / Jayce) have opted out of having their attack damage increased by 2 via the above +168% base stat buff STATISTICAL RENAMING "Per level" statistics have been renamed "growth" statistics to better reflect what's going on - see below for more information STATS GAINED PER LEVEL No longer linear. Instead, stats follow the following formula:

    Level 1: Immediately gain 0% of your growth statistic. All of your 'base stats' will be calculated off of this
    Level 2: Gain +72% of your growth statistic
    Level 3: Gain +75.5% of your growth statistic
    Level 4: Gain +79% of your growth statistic
    ... Gain +((Level*3.5 - 7) + 72)% of your growth statistic
    Level 18: Gain +128% of your growth statistic

TOO LONG, DIDN'T READ At level 18, you've gained +1700% of your growth statistic (this is slightly more than the old formula)

Source: 4.20 Patch Notes

The StatGain value for a given level is in fact (GrowthValue* ((ChampionLevel*3.5) + 65)/100)) My post was not completely accurate.I knew it looked off, and it didn't help that i didn't provide context.

Wow, i'm not sure you even read my post. Again all you posted was a formula to show the amount of stat gain you get from last level to next level. There isn't a formula you posted for complete current base stat at current level.

Base stat + (GrowthValue ((ChampionLevel3.5) + 65)/100)) = Is not your total current stat level. Try it.

But thanks for posting.

I'm merely pointing out the fact that you didn't look very hard since the formula was provided in the patch notes.

Either way, I did say Stat Gain for a given level.

Don't get mad because you didn't do your research or because you couldn't tell that I didn't retranscribe the formula correctly.

Ok, I think we're not understanding each other.

I'm saying that I had to figure out the following formula on my own. (The formula that calculates total base stat at current level) B = Original Base Stat, G = Growth Stat, L = Current Level Total Base Stat at Current Level = B + .65G(L-1) + .035G(1.5 + (.5L-.5))(L-1)

Your saying, that that formula is already posted somewhere? Can you show me exactly where, cause i've looked though all the growth stat pages, on lol, lol wiki, patch notes. Its not anywhere that I can tell.

Sorry, I didn't mean to sound mad or rude, its just i was very frustrated how much time I put into this, and it seemed like you posted the same information that was leading to my frustration.
