Osu Rework Calculator

What is an osu! Rework Calculator?

An osu! rework calculator is a tool designed to help players of the rhythm game osu! estimate how their total Performance Points (pp) and global rank might change following a major update to the pp system. The developers periodically “rework” the underlying formulas that calculate pp to better balance the game, reward a wider variety of skills, and fix exploits. A rework can significantly alter the value of a player’s existing scores, causing some to gain pp and others to lose it. This specific osu! rework calculator simulates these changes based on a defined set of adjustments.

This tool is for any active osu! player who is curious about the impact of pp changes. Whether you are a top player concerned about your rank or a casual player interested in how your skill set is valued, the osu! rework calculator provides valuable insights. A common misconception is that every rework is a nerf; in reality, reworks aim to rebalance, meaning skills that were previously undervalued (like high accuracy or complex rhythm) may receive significant buffs.

The osu! Rework Calculator Formula and Mathematical Explanation

The calculation logic of this osu! rework calculator is based on applying multipliers to your existing skill pp values and recalculating bonus pp. While every official rework has its own unique, complex formula, this tool uses a representative model to provide a realistic estimation.

The steps are as follows:

Input Existing PP: The calculator takes your current total pp from Aim, Speed, and Accuracy, which constitute the bulk of your weighted top performance pp.
Apply Skill Multipliers: Each skill component is multiplied by a specific factor. In this model, Accuracy is buffed (e.g., x1.12), Speed is slightly nerfed (e.g., x0.98), and Aim is moderately buffed (e.g., x1.05).
Recalculate Bonus PP: Bonus pp, derived from total score and play count, is also adjusted. The calculator uses a modified version of the standard bonus pp formula to reflect a potential rework.
Sum for New Total: The reworked skill pp values and the new bonus pp are summed to produce the final estimated pp total.

Variables Table

Variable	Meaning	Unit	Typical Range
Current Aim PP	The weighted total pp from aim-focused scores.	pp	1,000 – 15,000+
Current Speed PP	The weighted total pp from speed-focused scores.	pp	1,000 – 15,000+
Current Acc PP	The weighted total pp from accuracy-focused scores.	pp	1,000 – 15,000+
Play Count	The total number of maps played.	Count	10,000 – 200,000+

Variables used by the osu! rework calculator to estimate new pp values.

Practical Examples (Real-World Use Cases)

Example 1: The Accuracy-Focused Player

A player specializes in high-accuracy plays. Their pp distribution is heavily skewed towards accuracy.

Inputs: Aim PP: 3,000, Speed PP: 2,500, Acc PP: 6,000, Play Count: 80,000
Current Total PP (approx): 11,850 pp
Calculation with our osu! rework calculator:
- Reworked Aim: 3,000 * 1.05 = 3,150 pp
- Reworked Speed: 2,500 * 0.98 = 2,450 pp
- Reworked Accuracy: 6,000 * 1.12 = 6,720 pp
- Reworked Bonus PP: ~463 pp
Reworked Total PP (approx): 12,783 pp
Interpretation: This player sees a significant gain of over 900 pp because their primary skill (Accuracy) was heavily buffed by the rework.

Example 2: The Speed-Focused Player

Another player primarily farms high-speed, lower-accuracy maps.

Inputs: Aim PP: 4,500, Speed PP: 7,000, Acc PP: 1,500, Play Count: 120,000
Current Total PP (approx): 13,380 pp
Calculation with our osu! rework calculator:
- Reworked Aim: 4,500 * 1.05 = 4,725 pp
- Reworked Speed: 7,000 * 0.98 = 6,860 pp
- Reworked Accuracy: 1,500 * 1.12 = 1,680 pp
- Reworked Bonus PP: ~465 pp
Reworked Total PP (approx): 13,730 pp
Interpretation: This player still gains pp, but the gain is smaller (~350 pp). The nerf to Speed pp is offset by buffs to Aim, Accuracy, and Bonus pp, but their overall gain is less pronounced than the accuracy player’s. This demonstrates the rebalancing effect of a pp rework.

How to Use This osu! Rework Calculator

Using this osu! rework calculator is straightforward. Follow these steps to get your estimation:

Find Your PP Stats: Go to your osu! profile page. While the main page shows your total pp, you’ll need a browser extension like “osu!plus” to see the detailed breakdown of your Aim, Speed, and Accuracy pp from your top plays.
Enter the Values: Input the Aim, Speed, and Acc pp values into the corresponding fields in the calculator.
Enter Play Count: Find your total play count on your profile and enter it.
Review the Results: The calculator will instantly update, showing your estimated new total pp. The primary result highlights the new total, while the intermediate values show the change in pp and the difference in bonus pp.
Analyze the Chart: The bar chart provides a visual comparison of your pp components before and after the simulated rework, helping you quickly see which skills are most affected. Using an osu! rework calculator like this one is key to understanding your new standing.

Key Factors That Affect osu! Rework Results

Several factors determine whether you will gain or lose pp in a rework. Understanding them can help you adapt your playstyle. Using an osu! rework calculator helps visualize these factors.

Skill Balance: If your pp is heavily concentrated in a skill that gets nerfed (e.g., speed), you are more likely to lose pp or gain less. A balanced profile is more resilient to changes.
Accuracy Percentage: Reworks frequently increase the reward for high accuracy (99%+). Players with consistently high accuracy on their top plays tend to benefit the most.
Map Type Diversity: Players who only play one type of map (e.g., short farm maps) are vulnerable. Reworks often buff scores on longer, more stamina-intensive maps or technically complex maps.
Use of Mods: Some reworks adjust the pp multipliers for mods like Hidden (HD), Hard Rock (HR), or Flashlight (FL). A buff to a mod you frequently use can lead to large pp gains. For more info, check out our osu! Mod Guide.
Bonus PP Contribution: While minor for top players, bonus pp can be a factor. Reworks might change the formula, and having a high play count can provide a slightly larger cushion.
Star Rating (SR) Changes: The core of any rework is changing how map difficulty (SR) is calculated. If maps you have top scores on are re-rated higher, your pp will increase, and vice-versa. Our osu! rework calculator simulates the end result of these SR changes.

Frequently Asked Questions (FAQ)

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

No. This calculator uses a simplified, hypothetical model to provide a reasonable estimate. The official pp rework formulas are incredibly complex and are not public until implemented. This tool is for educational and entertainment purposes. For official numbers, always refer to your profile after the rework is complete.

2. Will I lose my rank after a pp rework?

It’s possible. Since pp reworks affect every player, the entire ranking ladder shifts. If you gain pp but players around you gain more, you could still lose ranks. Conversely, you could lose pp but gain ranks if others lose more. Using this osu! rework calculator gives you a hint of where you might land.

3. Why do developers rework the pp system?

The main goals are to balance the game, ensure all types of skills are rewarded fairly, and reduce the effectiveness of “farming” specific map types that give disproportionately high pp. It keeps the competitive scene healthy and evolving.

4. Where can I find my Aim, Speed, and Accuracy pp values?

The official osu! website does not display this breakdown. You will need to use a third-party browser extension like “osu!plus” or a site that analyzes player data. These tools inspect your top 100 plays and show the pp composition.

5. Does this calculator account for changes to specific mods like HD or FL?

This particular osu! rework calculator models the changes at the skill-type level (Aim, Speed, Acc) rather than the mod level. However, mod changes are a key part of official reworks and would be implicitly included in the changing value of your top plays.

6. What’s the difference between weighted pp and raw pp?

Your single highest pp score gives you 100% of its value. Your second-best score gives 95%, the third 90%, and so on. “Weighted pp” is the final pp you get from a score after this reduction is applied. The values you enter into the calculator should be the sum of these weighted values.

7. Why did my friend with lower skill gain more pp than me?

This often happens when your friend’s top scores align better with the goals of the rework. For example, if they had many high-accuracy scores that were previously undervalued, a rework buffing accuracy would benefit them immensely, even if their total pp was lower than yours to begin with.

8. How often do pp reworks happen?

There is no fixed schedule. Minor tweaks and major reworks happen periodically, sometimes with years in between major changes. They are announced on the official osu! blog and community forums. Keep an eye on community hubs to stay updated, and use an osu! rework calculator when news breaks.
