Pokémon Scarlet & Violet: Shiny Hunt Odds Planner (SV shiny odds calculator)

The base shiny odds in Pokémon Scarlet and Violet are 1 in 4,096 (approximately 0.024%) per encounter. This applies to all wild encounters, eggs, and static encounters without any boosts active. These are the standard Gen 9 shiny rates and have been consistent since Generation VI.

With the Shiny Charm equipped (obtained by completing the Pokédex), shiny odds improve to approximately 1 in 1,365 for wild encounters — roughly 3× better than the base rate. The Shiny Charm adds two extra "rolls" for a shiny check on each encounter.

Yes! The Shiny Charm stacks with Mass Outbreak bonus rolls. For example, a full 60+ cleared outbreak with the Shiny Charm reaches approximately 1/819 odds. When you add Sparkling Power Lv3 on top, the odds become approximately 1/512 — the best possible shiny odds in Scarlet and Violet.

Yes. Sparkling Power from sandwiches adds extra shiny rolls. Level 1 gives approximately 1/2,048 odds, Level 2 gives about 1/1,365, and Level 3 (the maximum) gives approximately 1/1,024 odds per encounter. It stacks with both the Shiny Charm and Mass Outbreak bonuses.

The best method depends on your goal. For the fastest overall shiny odds, combine Mass Outbreaks (60+ clears) + Sparkling Power Lv3 sandwich + Shiny Charm for approximately 1/512 odds. For specific Pokémon breeding, the Masuda Method + Shiny Charm gives 1/512 per egg. Use the calculator above to compare methods for your specific encounter rate.

It depends on context. The Masuda Method gives 1/683 odds per egg (or 1/512 with Shiny Charm), making it excellent for targeted species breeding. However, wild hunting with full boosts (outbreak + Sparkling Power Lv3 + charm) can also reach 1/512, and wild encounters are often faster per attempt. Use the calculator to compare based on your eggs-per-hour vs. encounters-per-hour rate. Also check our Pokémon GO Stardust Calculator for your GO resource planning.

At base odds (1/4,096), you need an average (mean) of 4,096 encounters for one shiny. The median (50% chance) is about 2,839 encounters. With full boosts at 1/512, the mean drops to 512 and the median to about 355. The calculator above computes both mean and median encounters for any combination of methods.

The best documented shiny odds in Pokémon Scarlet and Violet are approximately 1/512, achieved by combining: Mass Outbreak (60+ clears) + Sparkling Power Level 3 (sandwich) + Shiny Charm. The Masuda Method + Shiny Charm also reaches 1/512 for breeding.

Mass Outbreak shiny odds improve at two thresholds: after 30 clears, odds improve to approximately 1/2,048 (from the base 1/4,096). After 60 clears, odds improve further to approximately 1/1,365. These stack additively with Shiny Charm and Sparkling Power bonuses.

The sandwich must grant Sparkling Power specifically — other meal powers (like Encounter Power or Egg Power) do not affect shiny rates. The Sparkling Power level (1, 2, or 3) determines the bonus. The type of Sparkling Power (e.g., Fire, Water) only determines which Pokémon types get the boost, not the shiny odds themselves. Plan your sandwiches with our SV Sandwich Builder.

No. The Sparkling Power level (1, 2, or 3) determines the shiny odds bonus, not the type. Whether you have Sparkling Power: Fire, Water, or any other type, the shiny rate improvement is the same at each level. The type only affects which species get the boosted rate.

Mean encounters is the mathematical average (1/p) — the "expected value" if you repeated the hunt many times. Median encounters is the number of encounters needed for a 50% cumulative chance of finding at least one shiny. The median is always lower than the mean for shiny hunting because the distribution is right-skewed. For example, at 1/4,096 odds: mean = 4,096 but median ≈ 2,839.
