🤔 What is this tool?
A mathematical tool that replicates the mainline Pokemon game's damage engine.
🎯 What is it used for?
Competitive players use it to see if their attacks will knock out an opponent, or if they will survive a specific hit.
🛠️ How to use it?
Input the attacker's stats, the defender's stats, the move power, and check any multipliers like STAB or effectiveness.
⏰ When to use it?
Use it while building a competitive team to ensure you hit necessary damage thresholds.
Mastering Damage Ranges
In competitive Pokemon, guessing isn't good enough. You need to know if your Earthquake will achieve a One-Hit KO (OHKO) or leave the opponent with a sliver of health to retaliate. Our damage calculator runs the exact math the game uses, applying random rolls, STAB (Same Type Attack Bonus), and type effectiveness multipliers.
Knowing your damage ranges lets you confidently make plays, decide whether to risk a setup move, or safely switch out. We highly recommend running calculations for the biggest threats to your team before entering a tournament.
Frequently Asked Questions
How accurate is this damage formula?
This uses the standard generation 5+ damage formula used in the official games.
What is STAB?
STAB stands for Same Type Attack Bonus. If a Fire-type Pokemon uses a Fire-type move, it deals 50% more damage.
Are Critical Hits factored in?
Yes, you can toggle Critical Hits, which generally multiply damage by 1.5x (or 2x in older generations) and ignore defensive boosts.
Does it account for weather?
Weather multipliers (like Rain boosting Water moves) can dramatically shift damage ranges and should be calculated carefully.
Why is the damage a range instead of one number?
Every Pokemon attack rolls a random number between 0.85 and 1.0, meaning an attack can do slightly different damage each time.
What does OHKO mean?
OHKO stands for One-Hit Knockout. A guaranteed OHKO means even the lowest damage roll will defeat the opponent.
How do IVs and EVs affect damage?
Individual Values and Effort Values increase your Pokemon's raw stats, which directly feed into the damage formula multiplier.
Does this work for Pokemon GO?
No, Pokemon GO uses an entirely different damage and combat system. This is for the mainline games.
What about held items like Life Orb?
Held items apply specific multipliers (e.g., 1.3x for Life Orb) that significantly shift the minimum and maximum damage thresholds.
How do stat stages work?
Using moves like Swords Dance raises Attack stages. Each stage represents a 50% increase to the base stat in the formula.
