Formula Used
Average base hit = ((minimum damage + maximum damage) ÷ 2) + added flat damage.
Final hit = base hit × skill effectiveness × increased damage × more damage × resistance factor × damage taken factor × critical factor × uptime.
DPS = final hit × uses per second × hits per use. Burst DPS adds the burst more damage value. Fight DPS also adjusts for burst uptime and ramp time.
Physical EHP = life and shield ÷ final taken physical damage. The estimate uses armour, evasion, and block. Elemental and chaos EHP use resistance and block.
Mana time = unreserved mana ÷ net mana cost per second. If recovery is higher than cost, the result is marked stable.

POE 2 Build Planning Guide
A build calculator helps you test ideas before you spend currency. It turns gear values, skill choices, and defenses into clear numbers. This tool is made for flexible planning. You can model attacks, spells, minions, or hybrid setups by changing the input values.
Why Damage Estimates Matter
Damage in an action role playing build usually comes from many layers. Base weapon damage or spell damage starts the process. Skill effectiveness then scales that base. Increased damage adds one large pool. More damage multiplies after that. Critical chance and critical multiplier add expected value. Enemy resistance and penetration change the final hit. This calculator keeps those layers separate, so weak areas are easy to see.
Defense Is Not One Number
A strong build also needs survival. Life and energy shield form the main pool. Armour helps against physical hits. Resistance helps against elemental or chaos hits. Block and evasion reduce the number of hits that land. Recovery supports long fights. The calculator estimates effective hit points from these parts. It is not a replacement for in game testing, but it gives a useful planning target.
Resource Planning
Many builds fail because the main skill costs too much. Mana cost, use rate, and recovery decide whether the skill can run smoothly. The calculator checks net cost per second. It also estimates how long your unreserved mana lasts. This is useful when testing support gems, faster attacks, or cast speed changes.
How To Use Results
Start with your current character values. Enter average gear and skill numbers. Press calculate. Review damage, burst damage, effective life, and sustain. Then change one section at a time. Try a new weapon, more critical chance, better resistance, or extra recovery. Compare the exported results later.
Best Use Cases
Use this page during theory crafting. Use it when comparing two items. Use it before changing passive points. It also helps explain tradeoffs. A higher damage setup may lose sustain. A tankier setup may clear slower. Balanced builds usually feel better during mapping and bosses.
Keep the numbers conservative. Boss fights include movement, misses, and downtime. Leave space for mistakes, resistance penalties, and gear upgrades during progression. This makes planning safer for new leagues.
FAQs
What does this POE 2 build calculator estimate?
It estimates hit damage, sustained DPS, burst DPS, effective life, recovery, mana sustain, attribute needs, and a build score from your entered values.
Can I use it for attack and spell builds?
Yes. Enter weapon damage for attacks or average skill damage for spells. Adjust skill effectiveness, cast speed, damage multipliers, and hit count to match your setup.
Does it support minion builds?
Yes. Treat one minion hit as the base hit. Use hits per use for active minions or total attacking minions. Then adjust uptime and damage multipliers.
Why is my mana status marked stable?
Stable means your mana recovery per second is equal to or higher than your skill cost per second. Your main skill should sustain under those values.
How is critical damage included?
The calculator uses expected critical value. It multiplies normal damage by critical chance and the extra value from critical multiplier.
Is the defense score exact?
No. It is a planning estimate. Real combat includes monster types, debuffs, movement, recovery timing, avoidance streaks, and player decisions.
What is ramp time?
Ramp time is the delay before your build reaches full damage. Use it for poison stacks, minion setup, charges, exposure, or temporary buffs.
Why export CSV or PDF files?
Exports help compare builds later. Save one version before changing gear, passives, gems, or defensive layers. Then compare the results side by side.
