Formula used: CP = floor( (Base Attack + Attack IV) × √(Base Defense + Defense IV) × √(Base Stamina + Stamina IV) × CPM² ÷ 10 ), with a minimum of 10. CPM is the official CP Multiplier for the Pokémon’s level. HP = floor(CPM × (Base Stamina + Stamina IV)), with a minimum of 10.
Choosing which Pokémon to evolve can be tricky when Candy and Stardust are limited. A Pokémon with impressive CP before evolution may not always be the best choice for your next Raid team or GO Battle League lineup. The Pokémon CP Calculator helps you make more informed decisions before committing valuable resources.

The GameInfo Pokémon GO Evolution Calculator estimates how strong your Pokémon will become after evolution. Enter the Pokémon’s species and current Combat Power to see the predicted CP range for its evolved form. This is particularly useful when comparing multiple Pokémon of the same species.
What Does a Pokémon CP Calculator Do?
A Pokémon CP Calculator is an online tool that estimates Combat Power using a Pokémon’s species, current CP, and underlying game statistics. The GameInfo Evolution Calculator focuses on one practical question: how much CP might your Pokémon gain when it evolves?
For example, imagine you have two Charmander with different CP values. Instead of spending Candy immediately, you can compare their predicted Charizard CP ranges and decide which one deserves priority.
The calculator is useful for:
- Casual Trainers: Choose which Pokémon to evolve while saving Candy and Stardust.
- Raid players: Compare potential attackers before investing in a team.
- PvP competitors: Check whether an evolved Pokémon might exceed a league’s CP limit.
- Collectors: Make better decisions when several Pokémon are available for evolution.
You can also use the GameInfo CP Calculator when you want to explore CP, HP, level and Individual Values (IVs) in greater detail.
How to Use the GameInfo Evolution Calculator

Using a Pokémon CP Calculator takes only a few steps. Before starting, open Pokémon GO and check the current CP displayed on your chosen Pokémon’s summary screen.
Step 1: Open the Evolution Calculator
Visit the GameInfo Evolution Calculator page. It works through a web browser, so you can access it on a compatible desktop computer, tablet or mobile device.
Step 2: Select Your Pokémon
Find the Pokémon selection field and enter the name of the Pokémon you want to evolve. For example, you might choose Eevee, Charmander, Bulbasaur or Machop.
Make sure you select the correct species and form. Different regional forms or special variants may have different evolution outcomes.
Step 3: Enter Its Current CP
Open your Pokémon’s summary in the game and copy its displayed Combat Power into the calculator’s CP field. Enter the number carefully because an incorrect value can affect the usefulness of your estimate.
Step 4: Calculate the Evolution Result
Select Calculate to view the estimated CP of the evolved Pokémon. Depending on the information available, the tool may display a range rather than one guaranteed number.
Step 5: Compare Before Spending Resources
If you have several candidates, check each one before evolving. Consider its predicted CP alongside its appraisal, intended battle role, evolution cost and available moves.
Practical tip: A higher predicted CP is not automatically better. For competitive battles, IV distribution, Pokémon species, moves and league restrictions can matter more than raw CP alone.
Understanding Pokémon CP IVs, Levels and Evolution Mechanics

A Pokémon CP Calculator becomes much more useful when you understand what determines Combat Power. Two Pokémon of the same species can have different CP values because their levels and Individual Values are not necessarily identical.
What Determines Combat Power in Pokémon GO?
Combat Power, commonly called CP, is a combined measure of a Pokémon’s battle statistics. Pokémon GO uses three main attributes to calculate it:
- Attack: Influences the damage a Pokémon can deal.
- Defense: Helps determine how much damage it can withstand.
- Stamina: Represents its underlying endurance and contributes to its HP.
Each species has its own base stats. Individual Pokémon also have Individual Values (IVs), which provide additional points to their Attack, Defense and Stamina. Each IV ranges from 0 to 15.
For instance, a Pokémon with 15 Attack, 15 Defense and 15 Stamina IVs has a perfect IV spread, commonly written as 15/15/15. However, perfect IVs do not automatically make a Pokémon the best choice for every battle format.
The Pokémon GO CP Formula Explained
The underlying CP calculation combines base stats, IVs and a level-dependent CP multiplier (CPM). In simplified mathematical form, the formula is:
[
\mathrm{CP}=\left\lfloor
\frac{(B_A+IV_A)\sqrt{B_D+IV_D}\sqrt{B_S+IV_S}\times CPM^2}{10}
\right\rfloor
]
Here:
- (B_A), (B_D) and (B_S) represent the species’ base Attack, Defense and Stamina.
- (IV_A), (IV_D) and (IV_S) are the corresponding individual values.
- (CPM) is the multiplier associated with the Pokémon’s level.
- The floor symbol means the result is rounded down to a whole number.
Attack has a particularly strong influence on CP because it enters the formula directly, while Defense and Stamina enter through square roots. This explains why CP alone does not provide a complete measure of competitive usefulness.
Why Pokémon Level Matters
A Pokémon’s level affects its CP multiplier. Powering up a Pokémon increases its level and generally raises its CP, provided the game permits another power-up.
Pokémon GO allows levels to increase in half-level increments, with the standard maximum currently reaching level 50 under the usual level-up requirements. Certain special mechanics and temporary bonuses can affect the CP you see in battle, so distinguish a Pokémon’s underlying level from temporary effects.
A Pokémon CP Calculator can help estimate the result of an evolution, but a calculator that only receives species and current CP may not know the Pokémon’s exact IVs or level. This is why it can return a range instead of a guaranteed result.
Should You Evolve or Power Up First?
One of the most common questions among Trainers is whether powering up a Pokémon before evolution produces a better result. For the same Pokémon, with the same underlying IVs and level, evolving first or powering up first does not change its final CP simply because the order was different.
Evolution changes the Pokémon’s species and therefore its base stats. Powering up changes its level. The resulting CP depends on the evolved species, IVs and final level rather than the order in which you perform those two actions.
Comparing Both Approaches
| Approach | Main advantage | Potential drawback |
|---|---|---|
| Evolve first | Lets you inspect the evolved Pokémon and its resulting moves before investing more Stardust | You may need to power it up later |
| Power up first | Can be useful when a task specifically requires powering up a Pokémon | You may spend Stardust before confirming that the evolved Pokémon suits your needs |
For most Trainers, evolving first is a sensible resource-management habit when there is no reason to power up beforehand. Check the resulting Pokémon’s moves, battle role and CP before committing additional Stardust.
Remember that evolution can change a Pokémon’s moves. Do not assume that a particular move will remain available after evolution; check the current moveset and game mechanics before spending resources.
Using a Pokémon CP Calculator for Great League and Ultra League
A Pokémon’s predicted CP after evolution is especially important when preparing a team for the GO Battle League. A Pokémon that becomes stronger in a Raid may not fit the CP restrictions of a particular PvP league, so check the estimated result before evolving.
Great League: The 1,500 CP Limit
The Great League generally restricts eligible Pokémon to 1,500 CP or less. If your Pokémon’s predicted evolution range crosses this threshold, do not assume that the evolved form will qualify.
For example, suppose a Pokémon CP Calculator estimates an evolved CP between 1,460 and 1,520. The Pokémon might remain below the limit, but it could also exceed it. You need more precise information before making a decision.
Ultra League: The 2,500 CP Limit
The Ultra League generally has a maximum of 2,500 CP. When planning an evolution for this format, compare the predicted CP range with the league limit and consider whether the evolved species is useful in your intended team.
A result of 2,420–2,480 CP would fall below the standard cap across that estimated range. However, CP eligibility alone does not establish whether a Pokémon is competitive.
Which IVs Are Best for PvP?
For many Pokémon in Great League and Ultra League, a lower Attack IV combined with higher Defense and Stamina can allow the Pokémon to reach a higher level without exceeding the CP cap. This can result in greater overall bulk.
A spread such as 0/15/15 is often used as an illustrative PvP IV target, but it is not universally optimal. The best spread depends on the species, its stat distribution, the league and specific battle match-ups. Some Pokémon perform better with higher Attack.
For more precise planning, combine your Pokémon CP Calculator results with an IV checker and a species-specific PvP ranking resource.
How to Interpret an Evolution CP Range
Why does a Pokémon CP Calculator sometimes display two possible CP values instead of one exact answer?
The reason is that a Pokémon’s displayed CP does not uniquely identify its level and IV combination. Different combinations of these values can produce the same current CP but lead to different predicted CP values after evolution.
Use the range as a planning guide rather than a promise.
| Calculator result | What it means | Recommended action |
|---|---|---|
| Entire range below the league cap | The estimated outcomes remain within the standard CP limit | Check species suitability and moves |
| Range crosses the cap | Some possible outcomes may exceed the limit | Inspect IVs and level before evolving |
| Entire range above the cap | The estimated outcomes exceed the standard limit | Consider another candidate for that league |
| High predicted CP for Raids | The evolved Pokémon may have a useful CP for general battling | Compare Attack IVs, moves and species performance |
Important: A higher CP prediction does not automatically mean a better Pokémon. For Raids, Attack and suitable moves are important considerations; for CP-capped PvP, bulk and individual match-ups may matter more.
Common Pokémon CP Calculator Mistakes
Even a reliable calculator can lead to poor decisions if its results are interpreted incorrectly. Avoid these frequent errors.
1. Choosing only by CP. A high-CP Pokémon may have an unsuitable moveset or perform poorly in the role you need. Consider its species, IVs and intended use.
2. Treating an estimate as an exact result. When the tool displays a range, it is accounting for uncertainty in the information supplied. Use a more detailed IV and level check if the exact result matters.
3. Ignoring the evolved species. Evolution changes base stats, and the resulting Pokémon may serve a different battle role. Research the final form rather than judging only the pre-evolution.
4. Spending Stardust too early. If you have several candidates, compare them first. Evolving a Pokémon does not require you to power it up immediately.
5. Assuming perfect IVs are always best. A 15/15/15 Pokémon is excellent for many purposes, but a lower-Attack IV spread can be advantageous in some CP-limited PvP formats.
6. Forgetting evolution requirements. Some Pokémon require specific items, conditions or other steps to evolve. Check the in-game evolution button and current requirements before spending resources.
FAQs
Final Advice: Calculate Before You Commit
The GameInfo Pokémon Evolution Calculator is a practical starting point for deciding which Pokémon to evolve. Use its CP estimate to compare candidates, then check their appraisal and intended role before spending Candy or Stardust.
For PvP, confirm that the evolved Pokémon meets the relevant league cap and has suitable IVs and moves. For Raids, prioritise effective attackers rather than relying on CP alone. A little preparation can help you make better use of every evolution.
