A breakdown of how the osu! rework calculator adjusts different components of your score’s PP.
What is an osu! Rework Calculator?
An osu! rework calculator is a specialized tool designed for players of the rhythm game osu! to estimate how their performance points (PP) will change after a major update to the game’s scoring algorithm. The developers of osu! periodically “rework” the PP system to better reflect player skill, often by adjusting the weight of factors like accuracy, aim, speed, and combo. This osu! rework calculator simulates these changes, providing a valuable forecast for players curious about how their profile and rankings might be affected.
This tool is for any active osu! player, from those just starting to farm PP to top-level players. A common misconception is that every rework is a simple buff or nerf. In reality, reworks are complex and aim to rebalance the skills, meaning some of your scores might go up while others go down. This osu! rework calculator helps you understand that nuance.
osu! Rework Calculator Formula and Mathematical Explanation
The official osu! PP calculation is incredibly complex, but we can simulate its core principles. This osu! rework calculator uses a simplified model that reflects common rework goals, such as increasing the reward for high accuracy and penalizing misses more heavily.
The step-by-step logic is as follows:
- Establish a Base Value: The calculation starts with your score’s current PP, adjusted slightly by star rating, to create a ‘base pp’ for the rework.
- Apply an Accuracy Multiplier: A multiplier is calculated based on your accuracy. In this simulation, accuracy below 97% is nerfed (multiplier < 1.0), while accuracy above 99% is buffed (multiplier > 1.0). This reflects a common trend in reworks.
- Apply a Combo Multiplier: This multiplier assesses how much of the map’s total combo you achieved. Full combos (FCs) receive a 1.0x multiplier, while non-FCs are penalized based on how much combo was dropped.
- Subtract a Miss Penalty: A flat amount of PP is subtracted for each miss. Reworks often make misses more punishing, so this penalty scales aggressively with star rating.
This approach allows the osu! rework calculator to provide a realistic estimate of the rebalanced values.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| currentPP | The PP of the score before the rework. | pp | 50 – 1500 |
| accuracy | The play’s accuracy percentage. | % | 80.00 – 100.00 |
| starRating | The difficulty of the beatmap. | Stars (★) | 3.0 – 10.0 |
| comboRatio | Ratio of player’s combo to the map’s max combo. | Ratio | 0.5 – 1.0 |
| missCount | Total number of misses. | Count | 0 – 50 |
Practical Examples (Real-World Use Cases)
Example 1: The High-Accuracy Farm Map
- Inputs: Current PP: 350, Accuracy: 99.5%, Star Rating: 6.2, Combo: 1800/1800 (FC), Misses: 0.
- Analysis: Reworks often favor high-accuracy plays. The osu! rework calculator applies a significant buff via the accuracy multiplier. Since it’s a full combo, there is no combo penalty and no miss penalty.
- Estimated Output: The reworked PP would likely increase to around 375pp, as the system now better rewards the player’s precision.
Example 2: The Low-Accuracy Pass
- Inputs: Current PP: 500, Accuracy: 94.2%, Star Rating: 7.5, Combo: 1500/2500, Misses: 5.
- Analysis: This score relied on passing a difficult map, but with low accuracy and several misses. The osu! rework calculator applies a harsh accuracy nerf and a significant combo penalty for not achieving an FC. The 5 misses also subtract a large chunk of PP.
- Estimated Output: The reworked PP would likely drop significantly, potentially to around 430pp. This demonstrates the shift away from rewarding ‘bad’ passes on hard maps. Find out more with our osu pp calculator.

Key Factors That Affect osu! Rework Results
Several key factors determine how a score is affected when run through an osu! rework calculator. Understanding them is key to predicting changes.
- Accuracy: This is often the most important factor. Reworks almost always aim to make accuracy more important. Scores with 99%+ accuracy are often buffed, while those under 97% are often nerfed.
- Misses vs. Combo Breaks: Modern PP systems punish misses far more than combo breaks (slider breaks). A 1-miss play will almost always be worth much more than a 5-miss play, even if the combo is lower.
- Star Rating (SR): While SR determines the base potential of a map, its interaction with accuracy is key. A high-SR map played poorly will be worth less after a rework that emphasizes precision. A well-played medium-SR map may see a buff.
- Full Combo (FC): Achieving a full combo is a major threshold. A non-FC play will have a combo multiplier less than 1.0 in this osu! rework calculator, significantly reducing its value compared to an FC with similar accuracy.
- Aim vs. Speed PP: Some reworks target specific skills. A rework might nerf the PP gained from “speed” maps (streams) while buffing the PP from “aim” maps (jumps). Analyzing your top plays with a tool like a beatmap analyzer can reveal your exposure to such a change.
- Hidden (HD) Mod: Some reworks specifically rebalance mods. The Hidden mod, for example, has seen its multiplier adjusted in the past. This osu! rework calculator simulates a general rebalance, but specific mod changes can have a huge impact.
Frequently Asked Questions (FAQ)
1. Is this osu! rework calculator 100% accurate?
No. This is a simulation based on the principles of past reworks. The final, official PP values may differ as the exact formulas are complex and can be changed by the osu! developers before release. However, it provides a very strong and educational estimate.
2. Why did my PP go down on a high star rating map?
Your play likely had low accuracy or multiple misses. Reworks typically shift the focus from simply passing hard maps to playing them well. This osu! rework calculator simulates that by heavily penalizing poor accuracy on high-SR maps.
3. Why did a low star rating map give me more PP?
This can happen if you had an extremely high accuracy score (e.g., 99.8% or higher) on that map. Reworks often increase the reward for precision, which can sometimes push a well-played easier map above a sloppily-played harder map.
4. Does this calculator work for Taiko, Mania, or Catch?
This specific osu! rework calculator is designed and balanced for the standard osu! game mode. Other modes have entirely different calculation systems. You would need a separate calculator for them, like an osu!mania calculator.
5. What does “combo multiplier” mean?
The combo multiplier is a factor that reduces your score’s PP if you didn’t achieve a Full Combo (FC). It’s calculated as a ratio of your combo to the map’s max combo. The further you are from an FC, the lower the multiplier and the more PP you lose.
6. How often do PP reworks happen?
Major reworks happen periodically, sometimes once a year or even less frequently. There are constant small tweaks, but a large-scale rebalance that affects all scores is a significant event in the community.
7. Where can I find out more about map difficulty?
Understanding star rating is key to improving. Check out our guide on understanding star rating to learn more about how map difficulty is calculated and what it means for PP.
8. My aim is holding me back. How can I improve?
Many players struggle with aim consistency. Dedicated practice is key. We have compiled a guide on how to improve aim with tips and practice map suggestions.
