Pokémon Move Accuracy After Boost Calculator

Calculate the true accuracy of a Pokémon move after accounting for accuracy and evasiveness stage modifiers. Supports all generations from Red/Blue to Scarlet/Violet.

Interpreting Your Result

Reliable (100%+): Move will always hit unless interrupted. Gamble (70-85%): Standard for high-power moves. High Risk (<50%): Move is statistically likely to miss; consider switching or boosting.

✓ Do's

  • Use Hone Claws or Coil to fix low-accuracy moves like Stone Edge or Blizzard.
  • Switch out to reset negative accuracy stages (from Sand Attack or Mud-Slap).
  • Use moves that never miss (Swift, Aura Sphere) against Evasiveness-boosting teams.

✗ Don'ts

  • Don't use Focus Blast without an accuracy boost if you can't afford a miss.
  • Don't stay in against a Pokémon with Minsimize (evasiveness +2) unless you have a counter.
  • Don't forget that Switching resets all stat stages.

How It Works

The Pokémon Move Accuracy After Boost Calculator is a vital tool for competitive strategy. In Pokémon, moves are not just about power; they are about connecting. Accuracy (from the attacker) and Evasiveness (from the defender) work on a stage-based system from -6 to +6. These modifiers can turn a guaranteed 100% hit into a 33% gamble. This tool helps you calculate the "Net Stage" and resulting probability for any move in the game.

Understanding the Inputs

Base Accuracy: The base accuracy of the move (e.g., 70, 80, 100). Accuracy Stage: Your Pokémon's accuracy boost (-6 to +6). Evasiveness Stage: The opponent's evasiveness boost (-6 to +6).

Formula Used

Modified Accuracy = Base Accuracy × (Numerator / Denominator). Stage Multipliers: +1 (4/3), +2 (5/3), +3 (6/3), +4 (7/3), +5 (8/3), +6 (9/3). -1 (3/4), -2 (3/5), -3 (3/6), -4 (3/7), -5 (3/8), -6 (3/9).

Real Calculation Examples

  • 1Stone Edge (80%) with +1 Accuracy Boost: 80% × 1.33 = 106.6% (Guaranteed Hit).
  • 2Hydro Pump (80%) against +2 Evasiveness (Double Team): 80% × 0.6 = 48% Accuracy.
  • 3Focus Blast (70%) with -1 Accuracy (Sand Attack): 70% × 0.75 = 52.5% Accuracy.

Pokémon Move Accuracy After Boost Calculator: Mastering the Hit Roll

In the high-pressure environment of a Pokémon battle, "missing" is the most common cause of defeat. Whether it's a Focus Blast that whiffs exactly when you need it or a Stone Edge that fails three times in a row, accuracy is the invisible gatekeeper of victory. The Pokémon Move Accuracy After Boost Calculator is designed to remove the guesswork. By calculating the net modifiers of Accuracy stages and Evasiveness stages, trainers can determine if a 100% move is still a guaranteed hit or if it has become a 33% gamble.

Understanding the Stage System (Acc/Eva)

Both Accuracy and Evasiveness utilize a stage system ranging from -6 to +6. These stages operate on a specific set of fractions. When you use a move like Hone Claws, your Accuracy Stage increases by +1. When an opponent uses Double Team, their Evasiveness Stage increases by +1. The core calculation determines the "ratio" of these two numbers to find the final accuracy multiplier.

Comparison Table: Accuracy Multipliers per Stage

Stage Positive Stage Ratio Negative Stage Ratio Effective Percentage (of 100)
0 3/3 3/3 100%
+1 / -1 4/3 3/4 133% / 75%
+2 / -2 5/3 3/5 166% / 60%
+3 / -3 6/3 3/6 200% / 50%
+6 / -6 9/3 3/9 300% / 33.3%

The Net Stage Formula

To find the true accuracy of a move, you must first find the Net Stage. The formula is: Accuracy Stage - Evasiveness Stage. If the result is positive, use the numerator of (3 + Net). If the result is negative, use the denominator of (3 + |Net|).

Example:

If you have +1 Accuracy (Hone Claws) and your opponent has +2 Evasiveness (Double Team), your Net Stage is -1. A move with 80% base accuracy (like Hydro Pump) becomes 80% * (3/4) = 60%.

Common Moves and Items That Affect Accuracy

Our Accuracy Multiplier Calculator is essential for players using high-power, low-accuracy strategies. Common moves like Blizzard, Thunder, Fire Blast, and Focus Blast all sit in the 70-85% range. A single accuracy drop (e.g., from Leaf Tornado or Mud-Slap) can make these moves virtually unusable.

Recommended Items for Accuracy Correction:

  • Wide Lens: Increases accuracy by 10% (multiplicative). 70% becomes 77%.
  • Zoom Lens: Increases accuracy by 20% if the Pokémon moves after the opponent. 70% becomes 84%.
  • Victory Star (Ability): Increases accuracy of the user and allies by 10%.

Most Searched Results: Common Accuracy FAQ

  • "Can accuracy be boosted above 100%?" Yes. If a move's modified accuracy is 120%, it is a guaranteed hit. This is useful for counteracting an opponent's future Evasiveness boosts.
  • "Do Never-Miss moves ignore Evasiveness?" Yes. Moves like Aura Sphere, Aerial Ace, and Clear Smog (and several others) bypass the accuracy check entirely. They will land even if you are at -6 Accuracy and the opponent is at +6 Evasiveness.
  • "Does weather affect accuracy?" Yes. Thunder and Hurricane become 100% accurate in Rain. Conversely, Blizzard is 100% in Hail/Snow. In Sunny weather, Thunder and Hurricane drop to 50% accuracy.
  • "What is the cap for accuracy stages?" The cap for both stats is +6 and -6. Any further boosts or drops are ignored.

Risk Factors: RNG and "The Focus Blast Curse"

The "Focus Blast Curse" is a common meme in the Pokémon community, referring to the move's 70% accuracy feeling like 0% in critical moments. Using the Move Probability Calculator, you can see that a 70% move has a 30% chance to miss. Statistically, this means 1 out of every 3 uses will fail. When you factor in Evasiveness, that 1-in-3 becomes a 1-in-2 (50%). Understanding these risks is the difference between a mid-ladder player and a top-tier strategist.

Conclusion: Data Before Dice

Victory in Pokémon is a matter of minimizing the influence of luck. By using the Pokémon Move Accuracy After Boost Calculator, you convert "gut feelings" into hard data. Don't guess if your next Stone Edge will connect—know it. Use boosters, held items, and the stage system to your advantage, and never let a Leaf Tornado be the reason you lose a championship match. Data-driven trainers are winning trainers.

Frequently Asked Questions

Usage of This Calculator

Who Should Use This?

Competitive Pokémon trainers (VGC/OU), Speedrunners planning battle routes, and players frustrated by missing high-stakes moves.

Limitations

The calculator assumes the Move is not a "Never-Miss" move. It also does not account for specific weather-based changes (like Thunder in Rain).

Real-World Examples

The Sleep Powder Sweep

Scenario: A Venusaur with +1 Accuracy (from Coil or item) uses Sleep Powder (75%).

Outcome: 75% × 1.33 = 100% accuracy. The Venusaur now has a guaranteed sleep move.

Minimize Muk

Scenario: An opponent Muk uses Minimize (+2 Evasiveness). You use Earthquake (100%).

Outcome: 100% × 0.6 = 60% accuracy. You have a 40% chance to miss your most reliable move.

Summary

Master the math of the Hit Roll. Use the Pokémon Move Accuracy After Boost Calculator to find the true probability of your moves after Accuracy and Evasiveness stages.
