What is a Damage Calculator Smogon?

A damage calculator smogon is an essential tool for any serious competitive Pokémon player. It’s a digital application that simulates the complex damage formula used in the Pokémon games, allowing players to predict the outcome of specific matchups. By inputting variables like Pokémon stats, move power, items, abilities, and field conditions, a player can see the range of damage an attack will inflict. This knowledge is crucial for making informed decisions during a battle, such as whether to stay in and attack, switch to a more defensive Pokémon, or use a status move. These calculators are a cornerstone of platforms like Smogon and Pokémon Showdown, where competitive battling thrives.

The Pokémon Damage Formula and Explanation

The core of any damage calculator smogon is the official damage formula. While it has slight variations between generations, the modern formula is generally as follows:

Damage = ( ( ( (2 * Level / 5) + 2 ) * Base Power * (Attack / Defense) ) / 50 ) + 2 ) * Modifiers

This formula calculates a base damage value which is then multiplied by a series of modifiers to get the final result. Because of a random factor, the final damage falls within a range of 85% to 100% of the maximum calculated value.

Variables Table

Key variables in the Pokémon damage calculation.

Variable	Meaning	Unit	Typical Range
Level	The level of the attacking Pokémon.	Level	1 – 100 (50 for VGC)
Base Power	The intrinsic power of the move being used.	Power	10 – 250
Attack (Atk)	The attacker’s effective Attack or Special Attack stat.	Stat Points	5 – 500+
Defense (Def)	The defender’s effective Defense or Special Defense stat.	Stat Points	5 – 500+
Modifiers	A multiplier for STAB, type effectiveness, items, abilities, etc.	Multiplier	0.25x – 6.0x+

Practical Examples

Example 1: Special Attacker vs. Special Wall

Imagine a Level 50 Gengar (Special Attack: 359) using Shadow Ball (Base Power: 80) against a Level 50 Blissey (HP: 713, Special Defense: 405). Gengar gets STAB. Let’s see the calculation.

• Inputs: Attacker Level 50, Atk 359, Base Power 80; Defender HP 713, Def 405; STAB enabled.
• Result: The damage calculator smogon would show approximately 138-164 damage.
• Interpretation: This is roughly 19.3% – 22.9% of Blissey’s health. It’s a 5-hit KO, proving Blissey’s effectiveness as a special wall.

Example 2: Physical Attacker vs. Physical Wall

Consider a Level 50 Scizor (Attack: 394) with a Choice Band using Bullet Punch (Base Power: 40) against a Level 50 Skarmory (HP: 334, Defense: 416). Scizor gets STAB, but the attack is Not Very Effective (0.5x).

• Inputs: Attacker Level 50, Atk 394, Base Power 40, Choice Band; Defender HP 334, Def 416; STAB enabled, 0.5x effectiveness.
• Result: The calculator would show approximately 40-48 damage.
• Interpretation: This is a tiny fraction of Skarmory’s health. You can find more team-building tips at our team builder guide. This interaction shows why switching is a critical part of competitive play.

How to Use This Damage Calculator Smogon

1. Enter Attacker’s Stats: Input the attacker’s Level, the relevant offensive stat (Attack for physical moves, Special Attack for special), and the Base Power of the move.
2. Enter Defender’s Stats: Input the defender’s total HP and the relevant defensive stat (Defense for physical, Special Defense for special).
3. Set Modifiers: Check the boxes for STAB or Critical Hit if they apply. Adjust the Type Effectiveness dropdown based on the matchup. For more on matchups, see our type chart guide.
4. Select Items and Boosts: Choose any relevant items for both Pokémon and set any active stat stages from moves like Swords Dance or Nasty Plot.
5. Calculate and Interpret: Click “Calculate Damage” to see the results. The output will show the damage range, the percentage of the defender’s HP, and the likely number of hits to KO (nHKO).

Key Factors That Affect Damage

• STAB (Same-Type Attack Bonus): A Pokémon using a move that matches its type gets a 50% power boost. This is a fundamental principle in offensive calculations.
• Type Effectiveness: Super-effective moves deal double (2x) or quadruple (4x) damage, while not-very-effective moves deal half (0.5x) or a quarter (0.25x) damage. This is arguably the most important factor.
• Items: Items like Choice Band and Life Orb significantly increase damage output, while defensive items like Eviolite boost a non-fully-evolved Pokémon’s defenses.
• Abilities: Many abilities influence damage, such as Guts boosting Attack when statused or Thick Fat reducing damage from Fire and Ice moves.
• Stat Changes: Moves like Dragon Dance or Calm Mind raise stats, dramatically increasing damage potential. Conversely, moves like Intimidate lower stats, reducing incoming damage.
• Critical Hits: A critical hit typically ignores the attacker’s negative stat changes and the defender’s positive stat changes, and multiplies the final damage by 1.5.

Frequently Asked Questions (FAQ)

1. What does “nHKO” mean?

It stands for “n-Hit Knockout,” where ‘n’ is a number. For example, a “2HKO” means it will take two hits to knock out the Pokémon.

2. Why is there a damage range and not a single number?

The Pokémon damage formula includes a random multiplier that ranges from 0.85 to 1.0, creating a slight variance in every attack’s damage.

3. How does this calculator handle stat boosts?

It applies the standard multipliers for each stat stage. For example, a +1 boost multiplies the stat by 1.5, while a -1 boost multiplies it by roughly 0.67. Our EV/IV guide explains how to maximize these stats.

4. What is the difference between a tank and a wall?

A “wall” is purely defensive, meant to absorb hits repeatedly. A “tank” is also bulky but has significant offensive pressure to threaten the opponent back.

5. Is STAB factored in before or after type effectiveness?

All multipliers (STAB, type effectiveness, item boosts, etc.) are applied at the end of the calculation, multiplying together to form the final “Modifier.”

6. Does this calculator work for all Pokémon generations?

This calculator uses the modern formula (Generation V and later). Earlier generations, like RBY, had slightly different mechanics.

7. Why is level 50 the default?

Level 50 is the standard for official Video Game Championships (VGC) and most Smogon formats, making it the most relevant for competitive play.

8. What’s the best way to improve my team using this tool?

Use the damage calculator smogon to run calculations for common threats in the metagame. This helps you ensure your Pokémon can survive key attacks and deal enough damage back. Check our metagame analysis for current threats.
