Why It Exists
Most Elden Ring planning tools split stat planning, weapon AR comparisons, equip load, and rune costs across separate pages or separate sites entirely. This calculator was built to put all four in one view, so you can see how a single stat point changes your HP, your weapon's AR, your roll speed, and your leveling cost at the same time — without leaving the page or losing your place.
Methodology & Data
Every number this calculator produces — HP and FP curves, Stamina, equip load, weapon scaling grades, and rune costs — is built from Elden Ring's known stat-correction and leveling formulas, cross-checked against publicly documented breakpoints for soft caps and scaling grades. Curves are implemented as smoothed interpolation between known reference points rather than the game's exact internal tables, so results are approximate — usually within a small margin of the true in-game value, and consistent enough to compare builds against each other reliably. Where this matters — for example, rune costs at very high levels — the relevant guide says so explicitly rather than presenting an approximation as exact.
Keeping It Current
The calculator covers the base game and the Shadow of the Erdtree expansion. It's maintained on an ongoing basis; when a data error is found, it's corrected in the source and reflected here, not silently patched over.
Found a Mistake?
If a number here doesn't match what you're seeing in-game, please open an issue on GitHub with the specific stat, weapon, or level involved. Corrections are always welcome.
