Overview

FNCS rating: official events over the last year, 1.00 is the average lobby level. Rating = 0.3 × impact + 0.25 × K/D + 0.3 × points per match + 0.15 × survival; impact = 0.5 × kills + 0.35 × damage + 0.15 × damage trade, all relative to the lobby. In duos and trios Epic gives team numbers, so each member gets an equal share. Epic gives no damage for Divisional Cup, so it shows a dash.
Frame and number color is the stat level: red — low, yellow — average, green — above average, purple — far above (like the Unreal rank). Thresholds are a ROSTERA estimate from typical Fortnite tracker values (K/D around 1 and 2–5% wins is an average player), not Epic data; season counters have their own, lower thresholds.
Peak is the highest rank of the season, final is the rank at the season end (Epic data).
Matches may be grouped: Epic does not return single matches, a session is what changed between two profile refreshes.

How it is calculated

Epic does not report deaths, so K/D = kills ÷ (matches − wins).
The mode is inferred from Epic's playlist code — a heuristic, rare modes end up in “Other”.
Win % = wins ÷ matches × 100.
Kills per match = kills ÷ matches.
Time played is the Epic “minutes played” counter per playlist and input. For many matches from Fortnite’s early years Epic did not record time (under a minute per match) — for those, time is filled in with the player’s own average where time was recorded (excluding Creative). Creative and Playground count toward total time.
No zeros for unknowns: with no matches, ratios are not calculated.

Where these numbers come from

From the source (api-fortnite.com): matches, wins, kills, time played, last played.
Calculated by ROSTERA: win %, K/D, kills per match, modes from playlist codes, changes between snapshots.
Stored by the site: stat snapshots and name history since Oct 26, 2026
Season numbers and dates come from the API, names from a ROSTERA fallback list.
