CP combines species, appraisal and level

Combat Power is a compressed summary of a Pokémon’s battle stats. The number begins with the species form’s base Attack, Defense and Stamina from the Game Master. Your individual Pokémon adds an Attack, Defense and Stamina IV from 0 to 15. A CP multiplier, often shortened to CPM, then scales those totals for the Pokémon’s current level.

Forms matter. A regional, Mega or other alternate form can have a separate Game Master record. Choose the form shown in storage instead of assuming that every Pokémon with the same Pokédex number shares one stat line.

The established CP formula

The player community has validated this calculation against displayed game results:

floor((Base Attack + Attack IV) × √(Base Defense + Defense IV) × √(Base Stamina + Stamina IV) × CPM² ÷ 10)

The game applies a minimum of 10 CP. HP uses a related but simpler calculation: floor((Base Stamina + Stamina IV) × CPM), again with a minimum of 10.

Attack is not square-rooted, while Defense and Stamina are. That heavier Attack weighting explains why Attack IV can consume more of a Great or Ultra League CP budget. A low-Attack appraisal may fit an extra half-level beneath the cap and finish with more total bulk.

Pokémon level and the CP multiplier

The level displayed by calculators is the Pokémon’s level, not the Trainer level. Each power-up advances the Pokémon by one half-level. The CPM rises with level, and the formula squares it, so changing level affects every effective stat and the final CP.

The site stores reviewed multipliers locally. Its calculator does not need a live Niantic or community API while you use it, and a failed external service cannot prevent the calculation.

Why evolution changes CP

Normal evolution keeps the Pokémon’s IVs and level but replaces the current species base stats with those of the evolved form. The Pokémon GO Evolution Calculator performs both calculations with the same IV spread and CPM. A species whose evolved form has substantially higher base Attack will often show a pronounced CP jump.

Current CP alone cannot reveal one unique level and IV spread. Several combinations can floor to the same display value. When appraisal and level are unavailable, an honest evolution estimate is a possible interval rather than a guaranteed exact number.

Use the number with the right tool

Open the Pokémon GO CP Calculator for one auditable CP and HP result. Use the Stats Calculator when effective stats matter, the PvP IV Calculator for a league cap, and the Power Up Calculator before committing Stardust or Candy XL.

CP does not evaluate moves, type matchups, shields, breakpoints, weather or team role. It is an important roster number, but it is not a complete prediction of a battle.

Detailed player handbook

How to apply this Pokémon GO guide with confidence

Pokémon GO calculations combine species records, individual IVs, Pokémon level and a CP multiplier. Evolution changes the species base stats while normal powering up changes level; neither action should be described as rerolling IVs. League planning adds a CP cap, while Candy, Candy XL and Stardust determine whether a mathematically useful target is practical.

A strong build and blueprint planning workflow does more than produce a number. It preserves the inputs, explains the tradeoff and gives you a repeatable check when the game, your inventory or your goal changes. Use the sections below as a working notebook for How Pokémon GO CP Works, and update the baseline whenever new evidence replaces an assumption.

01 Establish a reliable baseline

Identify the exact species or form, record level in half-level increments and enter Attack, Defense and Stamina IVs separately. For an evolution, keep level and IVs fixed while changing the species record. For PvP, evaluate every eligible level beneath the selected cap and compare stat product within that one species and league.

Before entering anything, copy the relevant values exactly as the game displays them. Include the mode, platform, version and any active boosts or variants that can change the outcome. Save the first result before experimenting. That untouched baseline gives every later comparison a stable reference and makes input mistakes much easier to spot.

When a value is unknown, label it as an estimate and test a low and high case. Do not hide uncertainty behind extra decimal places. A transparent range is more useful than a precise-looking answer built from an unsupported assumption.

02 Compare options instead of chasing one score

Define dimensions, orientation, materials and the tolerance for asymmetry before placing the first block or point. Generate the smallest complete unit, verify its center and edges, then repeat it. A blueprint is most useful when each row or allocation can be checked independently rather than copied as one unexplained shape.

Create at least two realistic alternatives: the plan you can execute with current resources and the upgrade you are considering. Change one important input at a time, then write down what improved and what became worse. This prevents several simultaneous changes from receiving credit for the same improvement.

Look beyond the headline total. Time, reversibility, resource cost, risk and personal goals can change which option is actually better. The calculator provides structure for that decision; it does not remove the need to read the live game state.

03 Avoid the mistakes that create misleading answers

Off-by-one errors usually begin with mixing radius and diameter, including a center block inconsistently or mirroring from the wrong edge. Build reference axes first and count completed rows. For character builds, the equivalent mistake is spreading resources before the core threshold is reached.

Also check units and naming. Levels are not always total experience, percentages are not always multipliers, and two similarly named items may be different variants. If the result looks dramatically different from the game, assume an input or rule mismatch first. Re-enter the smallest possible example and confirm each step before restoring the full scenario.

Do not average incompatible sources merely to make them agree. Prefer the newest authoritative source for fixed mechanics and clearly dated community evidence for player-driven markets. Record which source supports each change so an update can be corrected without rebuilding the guide from memory.

04 Recheck the plan after updates

Check the Pokémon summary and appraisal before spending resources. Alternate forms, Shadows, Megas and game updates can change which record or modifier applies. Official help documents player-facing behavior, while the CP formula and Game Master fields are community interpreted; pages should label that distinction and show the review date.

Run a short control test after a major patch, season change or balance update. Use the same inputs as a saved baseline and compare the result with the current game. If the difference is repeatable, identify the smallest rule that explains it and update only that assumption. This is faster and safer than replacing every value at once.

Pay attention to dates on guides, videos and spreadsheets. A popular result can still describe an older version. When official notes are incomplete, mark the finding as observed and keep the test conditions visible until several independent repetitions support a firmer conclusion.

05 Work through a practical scenario

A low-Attack appraisal can look worse by total IV percentage yet reach another half level under the Great League cap. The resulting Defense and Stamina may raise stat product. That does not make it universally stronger, because moves, breakpoints and team matchups remain outside a pure IV ranking.

Start the worked example with the current state, not the desired result. Enter the baseline, duplicate it as a second scenario and modify only the decision being tested. Compare the difference, calculate the cost of the change and ask what would make the choice fail. If the plan still works under a conservative assumption, it is more likely to survive normal gameplay variation.

A successful blueprint can be paused and resumed without guessing. The player knows the total resource requirement, the next verified segment and which assumption controls the final shape or allocation. Small changes can be recalculated without discarding the whole project.

Final two-minute review

  • Are the game mode, version, platform and important variants recorded?
  • Did you preserve the original baseline before changing inputs?
  • Is every estimate labeled and tested as a range?
  • Did you compare the complete cost, risk and usefulness of each option?
  • Can you explain what new evidence would change the recommendation?
From reading to a decision

Apply this Pokémon GO guide in four passes
