I did a test...

With Spirit of Ancient Golem and +X% health from Runes and Masteries, the health formula is

Base HP * (1 + 1.25*X%) + Bonus HP * 1.25 * (1+X%)

I tested this with: Sivir at level 1 has 460 base HP. Her runes give her +4 HP/level and she has Veterans scars (+36 HP ) and Juggernaut (+3% health). She sat around in fountain afk until she could afford Spirit Visage (+200HP, +25% bonus HP)

So that's 460 base HP, and 240 bonus HP.

460 * (1 + 1.25*.03) + 240 *1.25*1.03 = 460 * 1.0375 + 240 * 1.2875 = 477.25 + 309 = 786.25 health, displayed as 787.

Interesting to note that without Spirit Visage, (460+40)*1.03 gave me 516 HP instead of 515. It was a custom game with an enemy sivir bot without runes or masteries that didn't have an extra health point. It must have sometthing to do with percent health multiplication giving sivir 515.00000000000001 HP or something?
