The WN8 Rating
WN8 is the community-standard skill rating for World of Tanks. It scores a player against the expectedperformance for each tank they drive, so a strong game in a weak tank counts for more than an average game in a meta tank. We compute it in our Rust engine using XVM's published expected-values table.
Performance, not raw output
Each tank has expected damage, frags, spots, defence, and win rate. WN8 measures how far above (or below) those expectations you play, weighted by how many battles you have in each tank.
Damage anchors the score
Damage carries the most weight, and the frag / spot / defence terms are capped relative to your damage ratio — so you can't farm a high WN8 on kills or spotting without doing the damage to back it up.
rDAMAGE = avgDamage / expDamage
rWIN = winRate / expWinRate
rFRAG = avgFrags / expFrags
rSPOT = avgSpots / expSpots
rDEF = avgDef / expDef
rDAMAGEc = max(0, (rDAMAGE − 0.22) / (1 − 0.22))
rWINc = max(0, (rWIN − 0.71) / (1 − 0.71))
rFRAGc = max(0, min(rDAMAGEc + 0.2, (rFRAG − 0.12) / (1 − 0.12)))
rSPOTc = max(0, min(rDAMAGEc + 0.1, (rSPOT − 0.38) / (1 − 0.38)))
rDEFc = max(0, min(rDAMAGEc + 0.1, (rDEF − 0.10) / (1 − 0.10)))
WN8 = 980 × rDAMAGEc
+ 210 × rDAMAGEc × rFRAGc
+ 155 × rFRAGc
+ 75 × rDEFc
+ 145 × min(1.8, rWINc)The clamped ratios (the c suffix) floor negatives at zero and tie frags/spots/defence to your damage ratio. Account WN8 is computed on the battle-aggregate — summed actual vs expected×battles across every tank — not as an average of per-tank WN8.
XVM's published table
We use the official per-tank expected values for damage, frags, spots, defence, and win rate maintained by XVM (modxvm.com), loaded from their daily wn8exp.json feed and read directly by the engine.
Tanks without an expected-values row show no WN8 until XVM adds them (newly-released vehicles can lag by a few days).
- WN8 never counts assistance (spotting/tracking) damage, which systematically undervalues scouts. Our WNX rating addresses exactly that — see the WNX reference.
- A handful of battles isn't a stable WN8. The rating settles as your sample grows; recent-window WN8 can swing hard on a few games.
- WN8 is a community standard, not a Wargaming metric. If XVM revises the expected-values table upstream, the numbers here shift once that table is refreshed.
