What is a Mythic Plus Calculator?

A Mythic Plus (M+) calculator is a specialized tool for World of Warcraft players that computes the score received for completing a Mythic+ dungeon. This score, often called M+ Rating or IO score, is a primary metric used by players to gauge skill and experience. It determines eligibility for joining higher-level groups and is a key component of seasonal progression. This mythic plus calculator helps you understand exactly how your keystone level and completion time translate into rating points for a specific dungeon.

This tool is essential for anyone serious about pushing M+ keys. Whether you are trying to achieve the Keystone Master achievement, improve your character progression, or simply see how a potential run might impact your overall score, this calculator provides immediate and accurate feedback. It demystifies the scoring system, showing that the final rating is a combination of the keystone’s base value and a significant modifier based on how quickly you beat the dungeon timer.

Mythic Plus Score Formula and Explanation

The Mythic+ scoring system rewards players for completing higher keys and for doing so quickly. The total score for a single dungeon is calculated by taking your best run (either Fortified or Tyrannical) and adding one-third of the score from your best run on the other affix. This encourages players to master dungeons under both conditions.

A single run’s score is determined by three main components:

1. Base Score: Each keystone level has a set amount of base points. A +2 keystone provides a baseline, with each subsequent level adding a fixed number of points.
2. Affix Score: Extra points are awarded for the active affixes, which begin at level +2, +7, and +14.
3. Time Bonus/Penalty: Completing a run faster than the dungeon’s timer grants bonus points. The faster you are, the more points you get, up to a cap. Conversely, exceeding the timer deducts points. If a run is significantly over time (more than 40% of the dungeon timer), it awards 0 points.

Variables in the Mythic Plus Score Calculation

Variable	Meaning	Unit / Type	Typical Range
Keystone Level	The difficulty level of the dungeon.	Integer	2 – 30+
Base Score	The points awarded just for the keystone level itself.	Points	~30 to ~250+
Completion Time	The time taken to finish the dungeon.	Minutes, Seconds	15:00 – 50:00
Dungeon Timer	The target time for the dungeon to receive full credit.	Minutes, Seconds	30:00 – 45:00
Run Score	The total points for a single Fortified or Tyrannical run.	Points	0 – 350+
Total Dungeon Score	The combined score from your best Fortified and Tyrannical runs.	Points	0 – 400+

Practical Examples

Example 1: A Strong Timed Run

A player completes a +15 Algeth’ar Academy well within the time limit.

• Inputs (Fortified): Keystone Level: 15, Completion Time: 25:00
• Inputs (Tyrannical): Keystone Level: 14, Completion Time: 29:30
• Dungeon Timer for Algeth’ar Academy: 30:00
• Results: The Fortified run was significantly under the timer, granting a large time bonus on top of a high base score. The Tyrannical run was also timed, but slower. The final score would be the full score from the +15 Fortified run, plus 1/3 of the score from the +14 Tyrannical run. This highlights the value of pushing keys on both affix weeks to maximize your overall rating.

Example 2: A Depleted Key

A group struggles in a +18 Ruby Life Pools and finishes over the timer.

• Inputs (Fortified): Keystone Level: 18, Completion Time: 35:00
• Inputs (Tyrannical): Best run is a timed +17.
• Dungeon Timer for Ruby Life Pools: 33:00
• Results: Since the +18 Fortified run was over the timer, it receives a penalty to its score. Even though the keystone level is high, the final rating for that run might be lower than a well-timed +17. This shows why using a mythic plus calculator is important: it demonstrates that simply completing a high key isn’t enough; speed is a critical factor for a high score.

How to Use This Mythic Plus Calculator

Using this calculator is simple and provides instant results for your M+ runs. Follow these steps to determine your score for any given dungeon:

1. Select the Dungeon: Use the dropdown menu to choose the dungeon you ran. The calculator automatically loads the correct base timer.
2. Enter Fortified Run Details: Input the keystone level and your completion time (minutes and seconds) for your best Fortified run in that dungeon. If you haven’t done one, you can leave the time blank or the level at 0.
3. Enter Tyrannical Run Details: Do the same for your best Tyrannical run. The most accurate score comes from providing details for both weeks.
4. Interpret the Results: The calculator will instantly display the individual scores for your Fortified and Tyrannical runs, and combine them into the “Total Score for this Dungeon” at the top. This is the score that contributes to your overall M+ rating. The bar chart provides a quick visual comparison of your performance on each affix.

Key Factors That Affect Mythic Plus Score

Several factors beyond just the keystone level influence your final M+ score. Understanding them is key to improvement.

• Completion Time: This is the most significant factor after key level. Finishing a dungeon faster directly translates to more points. Aim to beat the timer by a comfortable margin.
• Deaths: Every death adds 5 seconds to your completion time. Minimizing deaths is a crucial part of timing high keys and achieving a better score.
• Group Composition: A balanced group with strong crowd control, interrupts, and a Bloodlust/Heroism effect is vital for handling difficult pulls and bosses efficiently. Check out our class guides for tips.
• Route Planning: An efficient route that meets the enemy forces requirement without pulling unnecessary or dangerous trash packs saves a significant amount of time.
• Affix Management: Properly handling weekly affixes (e.g., Sanguine, Raging, Bolstering) prevents wipes and time loss. Each set of affixes requires a different strategy.
• Completing Both Affixes: Your total score for a dungeon is heavily weighted by your performance on both Fortified and Tyrannical weeks. Neglecting one will significantly lower your potential rating.

Frequently Asked Questions (FAQ)

What is a good Mythic Plus score?
A “good” score is relative. Typically, achieving a score of 2000 grants the “Keystone Master” achievement and is a common goal. A score of 2500+ is considered high and is often required for joining +20 keys and higher.

How is my total score from all dungeons calculated?
Your overall Mythic+ rating, the one shown in the group finder, is the sum of your scores from each individual dungeon. This is why it’s important to run all dungeons on both affix weeks. Our advanced player stats page can show your progress.

Why did I get 0 score for my run?
If you complete a dungeon more than 40% over its timer, the run is considered “massively depleted” and awards zero points, regardless of the keystone level.

Does the score from the weaker affix really matter?
Yes. While it’s only worth one-third of the main run, that “off-spec” score adds up significantly across all dungeons and is often the difference between score plateaus.

How can I improve my mythic plus score?
Focus on consistently timing keys, then push to higher levels. Analyze your runs to see where time was lost (e.g., deaths, slow pulls). Learn optimal routes and how to handle affixes. Using a mythic plus calculator helps track progress.

Do I need to input both Fortified and Tyrannical runs?
For the most accurate calculation of your total dungeon score, yes. If you only want to see the score for a single run, you can fill out just one side.

Are dungeon timers always the same?
No, Blizzard can and does adjust dungeon timers between seasons or even during a season to balance difficulty. This calculator is kept up-to-date with the latest timers.

What’s more important: key level or time?
Both are crucial. A higher key level provides a higher base score, but a fast completion time provides a massive bonus. A well-timed +19 will almost always give more score than a depleted +20.
