Chemistry
Approximate calculation — the real numbers can differ slightly in game. Boosts never push a stat above 99.
Chem Style Boost Calculator for FC 27
Enter a player's six base ratings, pick a chemistry style, and see the boosted ratings — before you spend the coins. Approximate math, 0–3 chemistry scaling, capped at 99.
How the boost works
The short version: a chemistry style's boost is only as good as the player's own chemistry. At 3 chemistry you get the full boost, at 2 about two thirds, at 1 about one third, and at 0 nothing. Two-stat styles (Hunter, Shadow) give a bigger per-stat boost (+3) than three-stat styles (+2), and Basic gives a small +1 on everything. Style group assignments match our chemistry styles guide.
Terms explained
- Chemistry points
- The player's individual chemistry (0–3), built from links to teammates sharing league, club and nation. It decides how much of the style's boost actually applies.
- Boost scaling
- The approximation this calculator uses: 3 chemistry = full boost, 2 chemistry ≈ two thirds, 1 chemistry ≈ one third, 0 chemistry = no boost. Fractional boosts are rounded down, so a small stat boost at low chemistry can round to zero.
- Style groups
- Which attribute groups a style touches. Two-stat styles give +3 per stat, three-stat styles +2 per stat, and Basic +1 on all six. The groups are taken from each style's own page on this site — nothing guessed.
- 99 cap
- Ratings cannot exceed 99 in FC 27, so boosted values are capped. A 98 with a +3 boost lands at 99, not 101.
What about goalkeeper styles?
Glove, Wall, Cat, Shield and Basic GK boost goalkeeper-only attributes (diving, handling, kicking, reflexes, positioning and speed) — not the six outfield stats this calculator works with. That is why the style list above is outfield styles only. It is a deliberate choice, not an oversight.
Boost calculator FAQ
How does a player's chemistry scale the style boost in FC 27?
The boost scales with the player's own chemistry points: 3 chemistry gives the full boost, 2 chemistry gives about two thirds, 1 chemistry about one third, and 0 chemistry gives no boost at all. This is the community-observed approximation — always check the in-game numbers.
Does a chemistry style give any boost at 0 chemistry in FC 27?
No. At 0 chemistry the style gives no boost at all. The style only starts working at 1 chemistry, which is why getting a player to 3 chemistry matters more than picking the perfect style.
Why is 99 the maximum boosted rating in this calculator?
Ratings in FC 27 cannot go above 99, so any boost that would push a stat past 99 is capped. For example, a 98-rated stat with a +3 boost becomes 99, not 101.
Are the boost numbers on this page exact?
No — they are an approximation of EA's boost rules: +3 per boosted stat for two-stat styles, +2 for three-stat styles, and +1 on every stat for Basic, scaled down by the player's 0–3 chemistry. EA does not publish the exact formula, so treat the results as an estimate and confirm in game.
