How Ratings Work

Ratings are 0 to 100 scores that show how you compare to the rest of the universe. Different rating categories are calculated in different ways, so the best way to climb depends on which category you care about.

The Important Idea

Most rating categories are not raw totals. They are normalized scores.

That means your rating depends on:

your own value
the current top value in the universe
sometimes the current bottom value in the universe

So a rating can change even when your account does not, because other players also keep moving.

Economy, Research, And Military Ratings

These three categories use the same style of formula. They read your current values from the live highscore tables and normalize them between the current minimum and maximum values in the universe.

rating
  = ((your_value - universe_min) / (universe_max - universe_min)) × 100

Plain-English Version

the current lowest valid score in the universe maps to 0
the current highest valid score maps to 100
everyone else falls somewhere in between

These categories currently use:

Economy Rating: your economy highscore
Research Rating: your research highscore
Military Rating: your military highscore

If there is only one valid score or everyone has the same value, a positive value rates 50 and zero rates 0 rather than dividing by zero. The selected galaxy's rankings and Ratings are separate from account-wide G.

Credits Rating

Credits uses the same 0–100 min/max formula, based on the current Credit balances of empires in your selected galaxy. The lowest balance scores 0 and the highest scores 100. If all balances are equal, a positive balance scores 50; zero balances score 0. Other galaxies and account-wide G are excluded.

Spending can lower your Credits rating; earnings can raise it. Ratings refresh hourly, so the category is a snapshot rather than your live wallet balance. Credits appears in your profile, radar, comparison and trend charts. History starts when the metric is first recorded; earlier snapshots stay blank. Credits does not contribute to your Overall rating.

Combat Rating

Combat Rating is more complex. It averages four separate combat performance scores, each compared against the current seasonal maximum.

The four pieces are:

win rate
total battles fought
total damage dealt
total resources raided

Win Rate Score

win_rate = battles_won / total_battles

win_rate_score
  = (your_win_rate / best_season_win_rate) × 100

The Other Three Combat Scores

Each one is relative to the current seasonal leader:

relative_score = (your_value / season_max_value) × 100

Final Combat Rating

combat_rating
  = average(
      win_rate_score,
      battles_score,
      damage_score,
      loot_score
    )

What This Means

winning efficiently matters
simply farming a high battle count also matters
damage and loot both matter separately

You cannot maximize Combat Rating with only one kind of activity.

Expansion Rating

Expansion Rating is based on how many holdings you own compared with the current largest empire in the universe.

expansion_rating
  = min(100, (your_total_holdings / universe_max_count) × 100)

This means:

your station holdings count
historical pre-conversion snapshots can include planets and moons
expansion is relative to the current biggest empire

Achievement Rating

Achievement Rating uses your total earned achievement points, but the current implementation does not compare you to the live universe max.

Instead, it currently normalizes against a fixed benchmark:

achievement_rating
  = (your_achievement_points / 5000) × 100

clamped to the 0 to 100 range.

That means Achievement Rating behaves more like progress toward a designed target than a live competitive ladder.

Overall Rating

Overall Rating is a weighted average of the category ratings.

Current weights:

Economy: 0.18
Military: 0.18
Research: 0.14
Combat: 0.18
Expansion: 0.14
Achievement: 0.10

Because those weights add up to 0.92, the game divides by the total weight to normalize the final answer:

overall_rating
  = (
      economy × 0.18
      + military × 0.18
      + research × 0.14
      + combat × 0.18
      + expansion × 0.14
      + achievement × 0.10
    ) / 0.92

Example

If your ratings are:

Economy 80
Military 70
Research 50
Combat 60
Expansion 40
Achievement 50

Then:

overall
  = (80×0.18 + 70×0.18 + 50×0.14 + 60×0.18 + 40×0.14 + 50×0.10) / 0.92
  = 60.2

How To Improve Each Rating

Economy

grow mines consistently
expand to more stations
protect your economy from repeated raids

Military

keep fleet value high
rebuild after losses quickly
protect ships from avoidable combat losses

Combat

win often
keep raiding
deal damage consistently during the season

Research

maintain RP income and invest in completed technology levels
prioritize long-term multiplier techs instead of only unlocks

Expansion

colonize aggressively
add stations within your capacity; new moons do not form in station mode

Achievement

chase point-rich milestones across several game areas

Important Caveats

Ratings are relative, so they can move when other players move.
A high overall rating does not always mean you are first in any single category.
Expansion and Achievement behave differently from Combat.
Achievement Rating currently uses a fixed 5,000-point benchmark, not a live universe leader.
