Example Data Table
| Move | Base Power | STAB | Type | Weather | Estimated Use |
|---|---|---|---|---|---|
| Thunderbolt | 90 | 1.5 | 2 | 1 | Strong electric matchup |
| Flamethrower | 90 | 1.5 | 1 | 1.5 | Sun boosted fire attack |

| Ice Beam | 90 | 1 | 4 | 1 | Double weakness coverage |
Formula Used
This calculator uses a practical version of the common Pokemon damage structure:
Damage = floor((((2 × Level ÷ 5 + 2) × Power × Attack ÷ Defense) ÷ 50 + 2) × Modifier)
The modifier combines STAB, type effectiveness, critical hit, burn, weather, screen, spread move, terrain, item, ability, and random damage roll. The calculator uses 0.85 for the low roll and 1.00 for the high roll.
How to Use This Calculator
Enter the move name and base power first. Add the attacking level, attack stat, and defending stat. Select STAB, type effectiveness, weather, terrain, critical hit, burn, and screen settings. Use custom item, ability, and move modifiers when a rule changes power. Press the calculate button. The result appears above the form and below the header.
Pokemon Move Power Planning Guide
Why Move Power Matters
Move power is more than the printed number beside a move. It changes with the user, target, field, item, and battle rule. A move with modest base power can become a winning option when the matchup is right. A stronger move can also fail when screens, resistance, burn, or weather reduce its final damage.
Understanding Base Power
Base power is the starting strength of a move. Moves like Thunderbolt, Flamethrower, and Ice Beam begin from a reliable value. Other moves change with speed, weight, friendship, status, or held items. This tool lets you enter a custom move modifier, so unusual moves can still be tested with practical accuracy.
Using Battle Modifiers
STAB is one of the most important bonuses. It rewards a Pokemon for using a move that matches its own type. Type effectiveness is often even larger. A super effective hit doubles the result. A double weakness can multiply it again. Weather, terrain, items, abilities, screens, and critical hits also change the final number.
Reading Damage Ranges
Pokemon damage usually has a random roll. This calculator shows a low and high estimate. The low value uses the common 85 percent roll. The high value uses the full roll. Average damage helps compare options quickly. It is useful for choosing between safe damage, coverage damage, and risky knockout attempts.
Planning Better Battles
Use the calculator before building a team, testing a move set, or writing a guide. Compare one move against several defenses. Change type effectiveness to study matchups. Add screen reduction for defensive teams. Add weather or terrain boosts for offensive plans. Export the result when you need records for notes, articles, or team sheets.
FAQs
What is move power?
Move power is the starting strength of a Pokemon attack. The final damage can change through stats, STAB, type matchups, weather, terrain, items, abilities, screens, and random rolls.
Does this calculator include STAB?
Yes. You can choose no STAB, normal STAB, or Adaptability STAB. This helps compare same-type attacks against coverage moves.
Can I calculate special moves?
Yes. Enter Special Attack as the attacking stat and Special Defense as the defending stat. The same damage structure works for special attacks.
What does type effectiveness mean?
Type effectiveness measures how well the move type hits the target. It can be zero, reduced, neutral, doubled, or quadrupled depending on the matchup.
Why is there a damage range?
Pokemon damage commonly uses a random roll. This calculator estimates the low roll at 85 percent and the high roll at full damage.
Can I use custom item modifiers?
Yes. Enter any item multiplier manually. For example, use 1.2 for a boosting item or 1 when no item affects damage.
Does the tool support spread moves?
Yes. Select the spread move option when a move hits multiple targets and the battle rule applies a spread damage reduction.
Is this exact for every game generation?
No. It is a practical advanced estimator. Some generations, moves, abilities, and edge cases use special rules that may require manual modifier adjustment.
