How To Use the Pokémon Damage Calculator

Here is what each box means and what you should put in it.

Pick the Game and Mode

Generation tabs (RBY to S/V): choose the game you play. The rules change with the game.
One vs One: one attacker against one defender. Best for most people.

Champions: use this tab for Pokémon Champions.

Choose the Pokémon

Pokémon 1 is the attacker and Pokémon 2 is the defender. Type a name in the top box and pick it from the list.
Type / Tera Type: filled for you. Tick the Tera box if the Pokémon is Terastallized.
Forme: pick a different form if the Pokémon has one.
Level: 100 for most battles, 50 for official Doubles.

Set the Stats

Base: comes with the Pokémon. Leave it as it is.
IVs: from 0 to 31. Most players use 31.

What Is a Pokémon Damage Calculator?

A Pokémon damage calculator tells you how much damage one Pokémon will do to another. You give it the two Pokémon, their moves, items and stats. It gives you back the exact damage, shown as a range and as a percent of the target’s HP.

Players use a damage calc to answer simple questions. Will my Pokémon survive that move? How many hits does it take to KO? Is it worth giving my Pokémon a Choice item? You can guess in a battle, or you can check the numbers first. The numbers are better.

Why Use a Damage Calculator?

Build a better team. See which EV spread makes your Pokémon take a hit it would otherwise miss.
Learn what you are facing. Test the Pokémon you meet most on ladder and see what beats them.
Save time. No need to do math by hand or lose a match to find out a move did too little.
Plan your turns. Know if a move is a sure 2HKO or only a coin flip.

How Is Damage Calculated in Pokémon?

From Gen 3 onward the base idea is the same. The game first finds a base number from the level, the move power and the attack and defense stats:

Damage = (((2 × Level ÷ 5 + 2) × Power × Attack ÷ Defense) ÷ 50 + 2) × Modifiers

This is the Pokémon damage formula in short. After that, the game multiplies the number by a set of modifiers. These are the common ones:

Modifier	What it does
Random roll	Damage is 85% to 100% of the full number (16 possible values)
STAB	1.5× when the move type matches the Pokémon’s type
Type matchup	0×, 0.25×, 0.5×, 1×, 2× or 4×
Critical hit	1.5× in newer games (2× in older ones)
Burn	Cuts physical damage in half
Weather	Sun and Rain boost or cut Fire and Water moves
Doubles spread move	0.75× when a move hits more than one target

Abilities, items, screens, terrain and many other effects add their own numbers on top. That is why a calculator is so useful. You pick the options, and it does all the math in the right order.

Good to know: the older games work a little differently. In Gen 1 (RBY), for example, critical hits depend on the Speed stat. Pick the right generation tab so the calculator uses the right rules.

How To Calculate Pokémon Damage Step by Step

Choose the generation tab for the game you play.
Pick the attacker in Pokémon 1 and the defender in Pokémon 2.
Set level, EVs, nature, ability and item for both.
Turn on the weather, terrain and screens that are active.
Click a move and read the result line.

If the line says “guaranteed 2HKO”, the move always KOs in two hits. If it says a percent chance, then it only works on some of the random rolls.

Understand the Result

Damage range

You see two numbers, like 162–192. The first is the lowest roll and the second is the highest. The percent next to it is the share of the target’s HP.

KO chance

The tool tells you if a move is a sure KO, a possible KO or not a KO. When it takes more than one hit, the calculator adds up the hits and checks every roll combination to give you the chance.

Possible damage amounts

This is the full list of the 16 random rolls. It is handy when you need to know exactly which rolls KO.

Use It as a Pokémon Stat Calculator

The boxes for base stats, IVs, EVs and nature also work as a quick Pokémon stat calculator. Change the EVs or the nature and the final stat updates next to it. You do not need a separate tool to find out what Speed or Defense a build ends up with.

Singles, Doubles and Pokémon Champions

In Singles you only need the field effects on each side. In Doubles, switch the field to Doubles and turn on helpers like Helping Hand, Friend Guard, Tailwind and Battery. For Pokémon Champions, click the Champions tab at the top. There is also a Random Battles tab and an Other Metagames tab if you play those.

Tips To Get the Most From It

Always check the nature and item. They change the result more than most people think.
Test the worst case. Use the highest roll and a critical hit to see if your Pokémon still lives.
Save good sets with Export so you can load them again in one click.
Make sure the level matches your format. Level 50 and level 100 give very different numbers.

Frequently Asked Questions

Quick answers about the Pokémon damage calculator.

The game takes the attacker’s level, the move power, and the attack and defense stats. It mixes them in one formula, then multiplies the result by things like STAB, type matchup, critical hit, weather, burn and a small random number. This calculator does all of that for you.

Pick your attacker in the Pokémon 1 box and the defender in the Pokémon 2 box. Set the level, EVs, nature, ability and item. Then click a move. The result line at the top shows the damage range, the percent of HP and how many hits it needs to KO.

Every attack gets a random roll between 85% and 100% of full damage. That gives 16 possible damage numbers. The calculator shows the lowest and the highest, so you can see the best and worst case.

The first games use older rules. For example, critical hits depend on the Speed stat of the attacker, and the random part works a little differently. Click the RBY tab at the top and the calculator switches to the Gen 1 rules.

When more than one hit is needed, it adds up the damage from each hit and checks all the possible roll combinations. The chance of a KO is the share of combinations that reach the target’s HP. The rest is the chance the move fails to KO.

Use the Import / Export box. Get your Pokémon as text from your game tool, teambuilder or emulator script, paste it in the box and press Import. The Pokémon loads with its moves, EVs, nature and item. You can also press Export to copy a set and save it.
