Example calculations
Tap an example to prefill the calculator with sample values.
Neutral mid-power hit
Level 50, 90 BP, STAB into a neutral target
A clean baseline for checking whether a common attack is threatening a KO without extra boosts.
Result: A safe damage band that often pressures a 2HKO but not an immediate knockout
Boosted super-effective swing
2x effective hit with a +1 attack boost
Useful for reading setup turns and deciding whether the opponent can still survive the follow-up.
Result: Often converts directly into an OHKO or very high KO odds
Resisted defensive check
A resisted hit into a boosted wall
Shows how sharply the damage floor falls when both typing and stat boosts work against the attacker.
Result: Usually chip damage that needs hazards or prior damage to matter
How the damage band is estimated
The calculator uses the standard structure of the Pokemon damage formula, then rolls through the 16 random damage values to produce a min-max band and a simple one-hit knockout chance. That makes it useful for quick competitive decision-making without a full sim.
Because you supply the final stats directly, the tool works best when you already know the set and just want to test a few move or matchup assumptions.
Pokemon damage FAQs
What the calculator models, what it leaves manual, and how to read the KO lane.
Is this a full battle simulator?
No. It is a streamlined damage estimator. It covers the core damage formula and common modifiers, but it does not model every ability, item, field effect, or edge case automatically.
Why does the calculator ask for stats directly?
That keeps it flexible. You can use the exact attack, defense, and HP numbers from the set you are testing without needing a built-in Pokedex or EV engine.
Can I use this for resisted or boosted hits?
Yes. Type effectiveness, STAB, attack boosts, defense boosts, and an extra general modifier field are all available for quick scenario testing.
