Pokémon Evolution Calculator (Pokémon GO Style)
Estimate evolved CP, candy usage, and total XP from your evolution session.
Optional: enter how many duplicate Pokémon you plan to transfer first.
How this Pokémon evolution calculator works
This tool is designed for players who want quick estimates before evolving Pokémon. It combines three practical calculations: projected evolved CP range, how many evolutions you can afford with your candy, and how much XP you can earn from a mass-evolution session.
Evolution in Pokémon GO uses hidden level and IV values, so no calculator can guarantee an exact CP every time without full game data. That is why this page returns a minimum and maximum CP range based on known evolution multipliers.
The basic formulas
- Estimated evolved CP:
Current CP × Evolution Multiplier - Total candy available:
Candies + Transfer Candy - Evolutions possible:
floor(Total Candy ÷ Candy Cost) - Total XP:
Evolutions × XP per Evolution × Lucky Egg Multiplier
Why the calculator gives a CP range instead of one number
If you have ever evolved two Pokémon with similar CP and got slightly different results, that is normal. Several factors impact final CP:
- Attack, Defense, and HP IV spread
- Internal level rounding during CP conversion
- Family-specific evolution multipliers
- Game updates that may adjust balancing over time
A range gives a realistic planning window, which is exactly what you need for raid prep, Great League builds, and Stardust budgeting.
Common candy costs and multipliers
| Family | Example Step | Candy Cost | Typical CP Multiplier |
|---|---|---|---|
| Bulbasaur | Bulbasaur → Ivysaur | 25 | 1.53×–1.70× |
| Pidgey | Pidgey → Pidgeotto | 12 | 1.50×–1.75× |
| Eevee | Eevee → Vaporeon/Jolteon/Flareon | 25 | 2.00×–2.40× |
| Magikarp | Magikarp → Gyarados | 400 | 10.00×–12.00× |
Best practices for evolution planning
1) Evolve low-cost families during XP events
Pokémon that evolve for 12 candy (like Pidgey, Caterpie, and Weedle) are excellent when you are optimizing XP, especially with Lucky Egg and event bonuses. Use the calculator’s candy and XP output to plan your evolution chain before you start.
2) Save high-IV Pokémon for final forms
If your goal is raid damage or PvP value, evolve only your strongest candidates and avoid spending candy on weak IV specimens. CP alone can be misleading; IV quality and moveset matter.
3) Use transfer math before evolving
A lot of players forget transfer candy and underestimate how many evolutions they can perform. Add planned transfers in the calculator to get a more realistic total.
Example scenario
Suppose you have a 500 CP Pidgey, 60 candies, and 8 duplicates to transfer:
- Total candy becomes 68.
- Pidgey → Pidgeotto costs 12 candy.
- You can evolve 5 times (with candy left over).
- Estimated evolved CP lands around 750 to 875.
- At 1000 XP each, that is 5,000 XP (or 10,000 XP with Lucky Egg).
This kind of preview is useful when deciding whether to evolve now or wait for a bonus event.
FAQ
Does this work for every Pokémon game?
No. This calculator is tuned for Pokémon GO-style CP and candy evolution planning.
Can this guarantee my final CP?
No calculator can guarantee exact values without full hidden stats and in-game rounding details. Use this as a strong estimate for planning.
What should I do if my result is slightly different in-game?
Small differences are expected due to IV distribution and level math. If accuracy is critical, appraise first and evolve one test Pokémon.
