What is a Smogon Calculator?

A Smogon calculator is a tool used by Pokémon players to determine the amount of damage a specific move will do to a specific Pokémon. It takes into account a wide range of factors, including the Pokémon’s stats, abilities, items, and the current battle conditions. This allows players to make informed decisions during battles, such as whether to attack, switch Pokémon, or use a defensive move. The name “Smogon” comes from Smogon University, a popular website for competitive Pokémon battling.

Smogon Calculator Formula and Explanation

The core of the Smogon calculator is the Pokémon damage formula. While the exact formula can be complex, a simplified version is as follows:

Damage = ((((2 * Attacker's Level / 5 + 2) * Move Power * Attacker's Attack / Defender's Defense) / 50) + 2) * Modifiers

Where “Modifiers” include factors like type effectiveness, critical hits, and items. Our calculator uses a more comprehensive version of this formula to ensure accuracy.

Variable Explanations

Variable	Meaning	Unit	Typical Range
Level	The Pokémon’s level	–	1-100
Attack/Defense	The Pokémon’s respective stat	–	5-500+
Move Power	The base power of the move	–	10-250

Practical Examples

Example 1: Strong Attacker vs. Bulky Defender

Let’s say a level 100 Garchomp with an Attack stat of 394 uses the move “Earthquake” (100 power) against a level 100 Skarmory with a Defense stat of 379 and 334 HP. The Smogon calculator would show that this is likely a 2-hit knockout, allowing the Garchomp player to plan accordingly.

Example 2: Special Attacker vs. Special Wall

A level 100 Gengar with a Special Attack of 394 uses “Shadow Ball” (80 power) against a Blissey with a Special Defense of 405 and 714 HP. The calculator will show this does very little damage, indicating it’s a bad matchup for Gengar.

How to Use This Smogon Calculator

Using this calculator is straightforward:

1. Enter the level and relevant attacking stat (Attack or Special Attack) for the attacking Pokémon.
2. Input the base power of the move being used.
3. Enter the level, relevant defensive stat (Defense or Special Defense), and total HP for the defending Pokémon.
4. Click “Calculate” to see the damage range and knockout possibility.

Key Factors That Affect Damage

• Stats: The higher the attacker’s offensive stat and the lower the defender’s defensive stat, the more damage is dealt.
• Types: Super-effective moves deal double damage, while not-very-effective moves deal half.
• Abilities: Many abilities can boost or reduce damage, like Intimidate or Flash Fire.
• Items: Items like Choice Band or Life Orb can significantly increase damage output.
• Critical Hits: A critical hit ignores the attacker’s negative stat changes and the defender’s positive stat changes, and deals 1.5x damage.
• Weather and Terrain: Conditions like sun, rain, or electric terrain can power up certain types of moves.

Frequently Asked Questions

What are EVs and IVs?

EVs (Effort Values) and IVs (Individual Values) are underlying stats that contribute to a Pokémon’s final stats. For simplicity, our calculator uses the final stat values directly.

How accurate is this calculator?

This calculator uses a simplified formula for demonstration. For precise competitive calculations, we recommend a full-featured calculator like the one on Pokémon Showdown.

What does ‘guaranteed 2HKO’ mean?

It means the move will knock out the opponent in two hits, guaranteed, even with the lowest possible damage roll.

Where can I find a Pokemon’s base stats?

Websites like Smogon’s own strategy Pokedex or Bulbapedia are excellent resources for finding a Pokemon’s base stats, movepools, and abilities.

Why does the calculator give a damage range?

The damage formula in Pokémon includes a random factor, causing damage to vary slightly. The calculator shows the minimum and maximum possible damage.

Can I use this for doubles battles?

This calculator is designed for single battles. Doubles battles have additional factors, such as the “spread move” damage reduction, that are not accounted for here.

What if a move has a variable power?

For moves with variable power like “Grass Knot” or “Heavy Slam,” you’ll need to determine the move’s power in that specific situation before using the calculator.

How do I account for stat changes?

For now, you must manually adjust the stat values in the input fields to reflect any in-battle stat boosts or drops.
