Pokémon Speed Calculator Formula
The Speed stat is calculated using a standard formula applied to all non-HP stats (Attack, Defense, Special Attack, Special Defense, and Speed) in Generation III onwards.
$$\text{Final Speed} = \left\lfloor \left( \left\lfloor \frac{(2 \times \text{Base Speed} + \text{IV} + \left\lfloor \text{EV}/4 \rfloor \right) \times \text{Level}}{100} \right\rfloor + 5 \right) \times \text{Nature Multiplier} \right\rfloor$$

Variables Explained
- Base Speed (BS): The inherent Speed value of the Pokémon species (ranges from 1 to 255).
- Level (L): The current level of the Pokémon (typically 50 or 100).
- Individual Value (IV): A random value assigned when the Pokémon is obtained, ranging from 0 (lowest) to 31 (highest).
- Effort Value (EV): Points gained from battling, maxing out at 252 for a single stat (or 508 total).
- Nature Multiplier (N): A 1.1 (beneficial), 1.0 (neutral), or 0.9 (hindering) multiplier applied by the Pokémon’s Nature.

What is the Pokémon Speed Stat?
The Speed stat (Spd) is arguably one of the most critical stats in competitive Pokémon battling. It determines which Pokémon attacks first during a turn. If two Pokémon use moves of the same priority, the one with the higher Speed stat moves first. This is crucial for gaining an advantage, whether by applying status effects, setting up defenses, or landing a decisive knockout blow before the opponent can react.
Unlike stats like Attack or Defense, the Speed stat is often “all or nothing.” A difference of even a single point can determine victory or defeat. Therefore, maximizing Speed is common for offensive Pokémon, using a beneficial Nature (Timid or Jolly) and 252 EVs. Conversely, low Speed is desired for strategies involving moves like Trick Room, where the slowest Pokémon moves first.
How to Calculate Speed (Example)
Let’s calculate the Speed of a Dragonite (Base Speed 80) at Level 50, with maximum investment (252 EVs, 31 IVs) and a beneficial Nature (Jolly/Timid, N=1.1).
- Determine EV Contribution: $\lfloor 252/4 \rfloor = 63$.
- Calculate Intermediate Term: $2 \times 80 + 31 + 63 = 160 + 31 + 63 = 254$.
- Apply Level Scaling: $\lfloor (254 \times 50) / 100 \rfloor = \lfloor 12700 / 100 \rfloor = 127$.
- Add Base Offset: $127 + 5 = 132$.
- Apply Nature Multiplier: $132 \times 1.1 = 145.2$.
- Final Result (Floor): $\lfloor 145.2 \rfloor = 145$.
The Dragonite’s final Speed stat is 145.
Frequently Asked Questions (FAQ)
The highest base Speed is 160 (Regieleki). When maximized (Level 100, 252 EVs, 31 IVs, 1.1 Nature), its final Speed stat reaches 504.
In the formula, every 4 Effort Values contribute exactly 1 point to the final stat at Level 100. At Level 50, 8 EVs contribute 1 point, reflecting the level scaling.
The Natures that boost Speed (1.1x multiplier) while lowering another stat are Timid (lowers Attack) and Jolly (lowers Special Attack).
No, the Speed stat only determines turn order. Critical Hit rate is determined by the move used and specific items (like Scope Lens) or abilities.
