What is a Mythic Plus Calculator?
A mythic plus calculator is an essential tool for World of Warcraft players who want to track their progress through the challenging Mythic+ dungeon system. This system, which scales infinitely in difficulty, provides players with a rating based on their speed and the level of the keystone they complete. Using a mythic plus calculator allows you to predict how much score you will gain from completing a specific run, helping you strategize which dungeons to prioritize for your seasonal goals.
Whether you are pushing for the “Keystone Master” (KSM) or “Keystone Hero” (KSH) achievements, understanding the math behind the points is vital. Many players mistakenly believe that just completing a higher level is always the best path, but the time taken and the performance on alternate affix weeks (Tyrannical and Fortified) play a massive role in your total standing.
Mythic Plus Calculator Formula and Mathematical Explanation
The rating system for Mythic+ has evolved. Currently, the calculation for a single dungeon run involves a base value determined by the level and a variable bonus based on the timer. The mythic plus calculator uses the following derivation:
- Base Score: 37.5 + (Keystone Level × 7.5)
- Time Bonus: Up to 7.5 points for finishing significantly under time (40% under par).
- Time Penalty: Points are deducted if you complete the dungeon after the timer expires, up to 15 points lost if 40% over.
Crucially, your total score for a single dungeon is calculated by taking 100% of your highest score (e.g., Tyrannical week) and adding 33.3% of your score from the other affix week (e.g., Fortified week).
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Level | Keystone Difficulty | Integer | 2 – 30 |
| Base Pts | Baseline points per level | Points | 52.5 – 262.5 |
| Time Bonus | Adjustment for speed | Points | -15.0 to +7.5 |
| Affix Multiplier | Secondary run weighting | Percentage | 33.3% |
Practical Examples (Real-World Use Cases)
Example 1: The Level 15 Run
Suppose you finish a +15 dungeon on time. The mythic plus calculator calculates the base points as: 37.5 + (15 * 7.5) = 150 points. If this is your first time in that dungeon for the season, and you do it on a Tyrannical week, your dungeon score becomes 150. When you later complete it on a +15 Fortified week, you get another 150, but it is weighted: 150 + (150 * 0.33) = ~200 total dungeon points.
Example 2: Over Time Completion
If you complete a +20 dungeon but miss the timer by 5 minutes on a 30-minute par, the mythic plus calculator will apply a penalty. The base points for +20 are 187.5. The penalty might reduce this to 180.0. It is still worth more than an on-time +18, but significantly less than a timed +20.

Key Factors That Affect Mythic Plus Calculator Results
- Keystone Level: The primary driver of score. Higher levels grant exponentially more difficult enemies but more points.
- Completion Time: Finishing at 60% of the timer yields the maximum 7.5 point bonus.
- Death Count: While deaths don’t directly reduce score points, each death removes 5 seconds from the timer, which might lead to a lower time bonus.
- Affix Weighting: Blizzard weights your best run at 100% and your second-best at 1/3 value.
- Season Scaling: Each season, the base numbers might shift slightly to accommodate new dungeons.
- Over-time Completion: You can still earn score if you finish within 40% of the par time, but it drops significantly after that.
Frequently Asked Questions (FAQ)
Q: Does completing a dungeon on both Tyrannical and Fortified weeks matter?
A: Yes! To maximize your score in the mythic plus calculator, you need completions on both types for every dungeon.
Q: What is the cap for the mythic plus calculator level?
A: Theoretically, there is no cap, but most players aim for levels 10-20 for rewards.
Q: Why did my score not go up after a run?
A: If the new run was lower level or much slower than your previous best for that affix, the score won’t update.
Q: How much score is needed for Keystone Master?
A: Usually 2000 points, which equates to timing roughly +15s on both affix weeks.
Q: Does the dungeon type matter for points?
A: No, all dungeons provide the same score for the same level and time percentage.
Q: Can I lose score?
A: No, your rating can only go up or stay the same; it never decreases.
Q: How does the time penalty work?
A: For every second over the timer, a small fraction of points is deducted from the base level value.
Q: Is there a difference between Raider.io and Blizzard score?
A: They use almost identical math now, though Raider.io might show more detailed historical data.
