How Many MMR Points Are in One Dota 2 Rank Medal Tier

Updated 2026-07-13

How much MMR is one Dota 2 rank medal star worth?

A single star inside a Dota 2 rank medal is commonly estimated at roughly 150-200 MMR, though this figure is approximate and periodically rebalanced by Valve rather than a fixed, published constant. Per the Dota 2 ranked system as documented on Liquipedia, the seven medal tiers below the top — Herald, Guardian, Crusader, Archon, Legend, Ancient, and Divine — each contain five numbered stars, so a full medal tier spans roughly five times that per-star figure, somewhere in the neighborhood of 750-1,000 MMR band-width, before a player crosses into the next tier up.

The one deliberately imprecise word in that estimate matters: 'roughly.' Valve has never published an exact, permanent MMR-per-star number, and the width of each band is not guaranteed to stay fixed release to release — Valve periodically rebalances rank distribution to keep medals meaningfully spread across the player population as the game's overall skill curve shifts over time. Any specific number quoted for MMR points per rank medal star, including the one in this article, should be treated as a useful approximation for converting a medal into a rough strength estimate, not a permanent conversion table.

How is a Dota 2 rank medal actually structured?

Each Dota 2 rank medal below the top tier is structured with five numbered stars, and a player's hidden MMR determines both which of the eight medal tiers they fall into and which of the five stars within that tier they currently hold. The eight tiers, from lowest to highest, are Herald, Guardian, Crusader, Archon, Legend, Ancient, Divine, and Immortal — Immortal is the exception to the star structure entirely, since Immortal players are ranked on the numeric regional Immortal leaderboard rather than being assigned a star count at all. A medal updates the moment a ranked win or loss pushes a player's hidden MMR across a star or tier threshold; there is no seasonal recalculation anymore, and recalibration after time away from ranked is optional rather than forced.

Why treat any specific MMR-per-star number as approximate?

Treat any specific MMR-per-star number as approximate because Valve controls the medal-to-MMR mapping internally and has changed rank distributions before, and nothing published guarantees the band width stays constant going forward. A number that was roughly accurate at one point in the game's history is not a permanent conversion table — it is a snapshot that can drift as Valve rebalances how medals map to the player population over time. Anyone using an MMR-per-star estimate for team balancing should treat it as a rough sizing tool for converting a medal gap into an approximate strength gap, not as a precise input worth defending down to the exact point.

This is also why star-level precision matters less than tier-level judgment for most balancing purposes. A player one star above another inside the same medal tier is a small, genuinely uncertain gap given how approximate the per-star figure is. A player several full medal tiers above another — Archon versus Divine is a three-tier jump, for instance — is a large and much more confidently real gap, because it spans many star-boundaries' worth of approximate MMR regardless of how wide any single star turns out to be.

How does a balancer use medal width without treating it as exact?

A balancer uses medal width as a rough strength estimate rather than an exact number by combining rank tier with recent win rate, which softens the imprecision an approximate per-star figure carries on its own. Dota 2 Groups converts each player's rank tier into a strength score using this kind of banded estimate, then adjusts it with win rate to place a player more accurately inside their tier than a star count alone could — a player near a star boundary with a strong recent win rate is treated as closer to the next star up, without needing to know the exact, unpublished MMR-per-star figure to make that adjustment.

This is also why the balance score is expressed as a percentage of total-strength parity rather than a claimed exact MMR gap in points — the underlying medal-to-strength conversion is intentionally approximate, so the balance score compares two teams' totals relative to each other rather than asserting a precise MMR figure for any individual player. That relative comparison holds up even if Valve quietly adjusts exactly how wide a star is.
