Elden Ring calculators. Make every level count.
Plan an Elden Ring character with transparent calculations—not guesswork. Compare starting classes, allocate your eight stats, budget runes, and find your equip-load tier.
Choose your tool
Explore seven reviewed tools including level 125/150/200 build budgets, Smithing Stone planning and an independent soft caps reference; experimental tools are clearly separated. Start with a build, compare starting classes, check equipment load or browse the level-up rune cost chart. Reference v1.17 AR passes 50 independently repeated same-input external-site comparisons; current-patch certified AR and enemy damage remain separate accuracy claims.
Build calculator & planner
Allocate all eight stats, calculate character level and runes, compare builds and try level 50/150 examples.
Open Elden Ring build calculator ↗Starting class optimizer
Compare ten original starting classes and their eight stats to find the lowest-level origin for your build.
Compare classes ↗Rune calculator
Plan your level-up costs and see how far your rune budget reaches.
Count runes ↗Equip load & roll calculator
Check exact 30% and 70% roll thresholds, with safe weight examples for your maximum load.
Check load ↗Respec calculator & stat planner
Compare all eight attributes before and after rebirth, preserving starting class and character level. Try verified same-level examples.
Plan a respec ↗Elden Ring soft caps
Understand Vigor 40/60, Mind and Endurance breakpoints, plus separate weapon and spell scaling returns, with official source caveats.
Explore stat breakpoints ↗Smithing Stone calculator
Calculate regular (+25) and somber (+10) upgrade stones, subtract shared inventory across multiple weapons, and export a checklist.
Count Smithing Stones ↗Which Elden Ring calculator should I use first?
Each reviewed tool answers a different question. Start with the problem you have in-game; these calculators do not substitute for one another.
I want to plan eight attributes for my character
Use the Build Calculator to distribute stats and calculate the resulting level. If you have not picked an origin yet, compare starting stat minimums and fresh-start rune cost in the Starting Class Optimizer first.
I need to know what leveling or upgrades cost
The Rune Calculator adds character level-up rune costs. The Smithing Stone Calculator separately counts weapon-upgrade materials and subtracts stones you already own. It does not calculate smithing rune fees.
I need to make an existing build playable
Enter actual equipped weight and maximum load in the Equip Load Calculator for light, medium or heavy roll thresholds. To redistribute points while keeping your starting class and total level, use the Respec Calculator. See Soft Caps before allocating points.
These are browser-based planning tools, not a promise of optimal gameplay. See our calculation methods and evidence limits.
Research & experimental tools
These additional calculators and community-reference tools are available to explore, but are not approved for Google indexing. Some models or individual data fields have limited validation, and results must not be treated as universally current-game verified. See the accuracy and source record before relying on them.
Weapon requirements
Check minimum weapon STR, DEX, INT, FAI and ARC for one- or two-handed use.
Check requirements ↗Custom armor optimizer
Optimize 13 published armor stats, including physical/elemental negation, with an exact minimum Poise and roll-weight limit using an opt-in community reference.
Optimize armor ↗Weapon database
Search 487 uniquely named weapon and shield references (377 base-game, 102 Shadow of the Erdtree, 8 Tarnished Pack). 72 base-game entries were recovered by reverse matching pinned Regulation 1.17: their minimum attributes are sourced but attack/weight/critical/scaling remain unknown. Including 102 Shadow of the Erdtree entries (102 with sourced +0 base-attack facts) and 8 Tarnished Pack armaments (8 with separately sourced community +0 base facts; remaining requirements/weight only, with 1 new source-disputed shield). Source versions and current-patch game accuracy remain unverified. These are not player Attack Ratings.
Browse real weapons ↗Weapon AR calculator
Choose a real weapon, source-defined affinity, upgrade and your attributes to calculate v1.17 reference attack rating. 15 live Tarnished.dev comparisons matched.
Calculate reference AR ↗Damage Calculator
Estimate per-hit damage and DPS from weapon AR, motion value and eight manually entered enemy defenses and negations. Research model, not validated Tarnished.dev damage parity.
Preview damage ↗Know the limits.
Trust the result.
Every number should have a method. We publish level and load calculations with validation notes, while experimental weapon AR remains clearly separated from real-game results.

Weapon AR is being validated
A new weapon reference now includes real names and community-reported base stats. The separate AR research workbench uses fictional or local imported parameters. Our independent v1.17 reference AR engine now matches 50 of 50 independently repeated Tarnished.dev v1.17 browser cases across twelve weapon families, including DLC, Regular/Somber upgrades, elemental/status affinities and 1H/2H. Free opt-in pinned-source calculations remain in the local Weapon Data Workbench; no game installation is needed. Current-patch game-certified AR, enemy damage and complete armor data remain distinct and unverified.
