What is an osu! Rework PP Calculator?

An osu! rework calculator is a specialized tool designed to estimate the Performance Points (PP) a player would earn for a score under a new or updated version of osu!’s PP system. The game’s developers periodically “rework” the formula to better balance scoring across different skills like aim, speed, and accuracy. This means a score’s PP value can change significantly overnight. Our osu! rework calculator helps you anticipate these changes and understand how your top plays might be affected, which is crucial for any player serious about their rank.

This tool should be used by any competitive osu! player, from those breaking into 5-digit ranks to top players trying to optimize their profiles. A common misconception is that reworks always “nerf” farm maps; in reality, they often buff undervalued skills, making a different class of maps more rewarding. This osu! rework calculator clarifies that.

osu! Rework PP Calculator: Formula and Mathematical Explanation

The core of any osu! rework calculator is its formula. While the official formula is incredibly complex, we can understand it through a simplified model. The calculation is a multi-step process that evaluates different aspects of your play.

1. Base Difficulty Calculation: First, the calculator determines the base PP values for the three core skills: Aim, Speed, and Accuracy. These are derived from the map’s star rating (SR).
   • Aim PP is calculated from the map’s aim SR, rewarding precision on jumps and complex patterns.
   • Speed PP comes from the speed SR, rewarding the ability to handle fast streams and high BPM sections.
   • Accuracy PP is derived from the map’s Overall Difficulty (OD) and rewards maintaining high accuracy.
2. Total Base PP: These base values are combined using a weighted formula, typically an exponential sum, to find the “perfect score” PP before penalties. A common approach is (Aim^1.1 + Speed^1.1 + Acc^1.1)^(1/1.1).
3. Scaling and Penalties: This is where your personal performance comes in. The base PP is heavily scaled by:
   • Accuracy Modifier: A massive penalty is applied for lower accuracies. An accuracy of 95% might yield only 70-80% of the possible PP from a 100% score.
   • Combo Modifier: A significant portion of PP is tied to combo. Breaking combo reduces the potential PP, scaled by how much of the map’s max combo you achieved.
   • Miss Penalty: Each miss applies an exponential penalty, often around 0.95^misses, quickly diminishing the final PP value.

Understanding these factors is key to using an osu! rework calculator effectively. It’s not just about passing a map; it’s about how well you do it.

osu! Rework Calculator Variables

Variable	Meaning	Unit	Typical Range
Aim/Speed Stars	Difficulty rating for aim or speed skill.	Stars (SR)	2.0 – 10.0+
Accuracy	Player’s score accuracy.	Percentage (%)	80.00 – 100.00
Combo	Player’s highest combo achieved vs. the map’s max.	Count	0 – 5000+
Misses	Number of missed circles or slider ends.	Count	0 – 50+

Practical Examples of the osu! Rework PP Calculator

Let’s look at two scenarios to see how the osu! rework calculator works in practice.

Example 1: High Accuracy, One Miss

• Map Stats: 6.5 Aim SR, 6.2 Speed SR, 2000 Max Combo
• Player Score: 99.5% Accuracy, 1850 Combo, 1 Miss

The osu! rework calculator would first determine the high base PP from the 6-star ratings. The 99.5% accuracy retains most of the potential value. However, the combo break at 1850/2000 and the single miss will apply a noticeable penalty. The final estimated PP might be around 550pp, whereas a full combo (FC) might have been over 620pp. This shows how crucial maintaining combo is.

Example 2: Low Accuracy, Full Combo

• Map Stats: 7.0 Aim SR, 7.0 Speed SR, 1500 Max Combo
• Player Score: 96.0% Accuracy, 1500 Combo (FC), 0 Misses

In this case, the player achieved a full combo, which is a huge bonus. However, the 96% accuracy will severely reduce the PP. An osu! rework calculator would show that even though the map is harder and it was an FC, the low accuracy might result in a score around 520pp. This highlights that after the rework, accuracy is often weighted more heavily than ever before. Using an osu! rework calculator can help a player decide whether to grind for higher accuracy on an existing FC.

How to Use This osu! Rework PP Calculator

1. Enter Map Difficulty: Input the Aim and Speed star ratings for the map. You can get these from in-game or from sites like the osu! Beatmap Analyzer.
2. Enter Your Score Details: Fill in your accuracy, your max combo, the map’s max combo, and your miss count. Be as precise as possible.
3. Analyze the Results: The osu! rework calculator will immediately display the total estimated PP. Pay close attention to the intermediate values for Aim, Speed, and Accuracy PP to see where the value is coming from.
4. Review the Chart and Table: Use the dynamic chart and breakdown table to understand how your PP would change with different accuracies. This is vital for deciding if it’s worth replaying a map for a 1% accuracy improvement.

Key Factors That Affect osu! Rework Calculator Results

• Accuracy: This is arguably the most important factor. The rework formulas are increasingly punishing for low accuracy. A 1% gain from 98% to 99% can be worth more PP than a 1% gain from 90% to 91%.
• Combo: Missing near the end of a map is less punishing than missing at the beginning. The calculator’s combo scaling reflects that a high percentage of the map’s max combo is crucial.
• Misses: The exponential penalty on misses means that the first miss is the most costly. Going from 1 miss to 0 (an FC) provides a massive PP boost.
• Map Difficulty (SR): Higher star ratings provide a higher base PP value to be scaled. This is the foundation of any score. Check our guide on Choosing the Right PP Maps.
• Map Length: Longer maps often have a bonus that rewards stamina, though recent reworks have tried to balance this to avoid over-weighting marathon maps.
• Mods: Mods like Hidden (HD), Hard Rock (HR), and Double Time (DT) apply multipliers to the final PP value. This calculator assumes no mods, but you can learn more at our Mod Multiplier Guide.

Frequently Asked Questions (FAQ)

1. Is this osu! rework calculator 100% accurate?

No, it provides a highly educated estimate. The official calculation is closed-source and runs on the server, but this tool uses a robust model based on the known principles of the rework.

2. Why did my PP go down after a rework?

Your top scores were likely on maps that were considered over-weighted by the old system (e.g., short, farmable jump maps). The rework re-balances PP to reward a wider range of skills.

3. Does Overall Difficulty (OD) affect the PP from this calculator?

Yes, indirectly. Higher OD makes achieving high accuracy more difficult, which in turn lowers your accuracy input and thus your final PP. The base Accuracy PP value is also derived from OD.

4. How does this osu! rework calculator handle mods?

This calculator is “mod-neutral.” To estimate a modded score, you would first find the modded star rating and OD before inputting them. For example, DT increases SR significantly.

5. What’s the difference between Aim and Speed stars?

Aim stars measure the difficulty of cursor movement (jumps, patterns), while Speed stars measure the required tapping speed and stamina (streams). A good player needs both.

6. Can I see how much PP I will gain overall?

This tool calculates PP for a single score. To see your total rank change, you would need a tool that analyzes your top 100 plays, like our osu! Profile Analyzer.

7. Where can I find the star rating for a map?

You can find it in-game by selecting a map, or on the official osu! website on the beatmap’s page. Third-party tools can also provide a more detailed breakdown.

8. Why is a full combo (FC) so important?

An FC (0 misses and max combo) avoids both the miss penalty and the combo scaling penalty, unlocking the score’s maximum potential PP for that accuracy. It’s a huge milestone for any score.
