Ragnarok Online character stats and damage
This free RO stat calculator helps you compare character builds before spending your stat points or choosing equipment. Calculate HP, SP, ATK, MATK, ASPD, HIT, FLEE and critical chance, then estimate damage against a monster or another character.
How to use RO Calc
- Choose your class, base level and job level. Set STR, AGI, VIT, INT, DEX and LUK.
- Add equipment, refinements, cards, learned skills and buffs. Change one choice to compare its effect on your stats.
- Choose a target and attack skill to check damage, hit chance, cast time and estimated battle duration.
Find equipment in the Renewal item database, compare monster stats, or plan prerequisites in the RO skill simulator.
Renewal character builds
This Renewal calculator uses Renewal rAthena rules for character stats, equipment and combat. Trait stats appear for characters that support them, and equipment and monster data follow the Renewal database.
Use the game-version switch above the calculator to compare the same build in Pre-Renewal. Each version applies its own requirements and formulas.
Private servers can change items, skills and combat settings. The calculation details identify the data source, and the advanced build options let you explore equipment outside normal requirements.
Before you start
Is this a stat calculator or a character simulator?
Both. Start with base stats, or build a complete character with equipment, cards, skills and buffs. The combat estimate adds PvM, MVP, PvP and War of Emperium scenarios.
Can I save and share my character build?
Use Save / load to keep a build in this browser. Share build copies a link containing your setup, so another player can open it in the same game version. No account is needed.
Why can damage differ from my server?
The calculator uses a specific rAthena data snapshot and samples attacks under the selected conditions. Server customizations, battle settings and situations outside that setup can change the result. Open Calculation details & sources for the reference.
